The U.S. Environmental Protection Agency (EPA) is charged by Congress with protecting the nation's
land, air, and water resources. Under a mandate of national environmental laws, the Agency strives to
formulate and implement actions leading to a compatible balance between human activities and the ability
of natural systems to support and nurture life. To meet this mandate, EPA's research program is
providing data and technical support for solving environmental problems today and building a science
knowledge base necessary to manage our ecological resources wisely, understand how pollutants affect
our health, and prevent or reduce environmental risks in the future.

The National Risk Management Research Laboratory (NRMRL) is the Agency's center for investigation
of technological and management approaches for preventing and reducing risks from pollution that
threaten human health and the environment.  The focus of the Laboratory's research program is on
methods and their cost-effectiveness for prevention and control of pollution to air, land, water, and sub-
surface resources; protection of water quality in public water systems; remediation of contaminated sites,
sediments and groundwater; prevention and control of indoor air pollution; and restoration of ecosystems.
NRMRL collaborates with both public and private sector partners to foster technologies that reduce the
cost of compliance and to anticipate emerging problems. NRMRL's research provides solutions to envi-
ronmental problems by developing and promoting technologies that protect and improve the environment;
advancing scientific and engineering information to support regulatory and policy decisions; and provid-
ing the technical support and information transfer to ensure implementation of environmental regulations
and strategies at the  national, state, and community levels.

This publication has been produced as part of the Laboratory's strategic long-term research plan.
It is published and made available by EPA's Office of Research and Development to assist the user
community and to link researchers with their clients.

                                         ABSTRACT


This report documents the activities performed during and the results obtained from the arsenic removal
treatment technology demonstration project at Oregon Institute of Technology (OIT) at Klamath Falls,
OR. The objectives of the project were to evaluate:  (1) the effectiveness of three point of entry (POE)
adsorptive media (AM) systems, all manufactured by Kinetico, and two types of point of use (POU) AM
units, one manufactured by Kinetico and the other by AdEdge, in removing arsenic to meet the maximum
contaminant level (MCL) of 10 |o,g/L, (2) the reliability of these POE/POU treatment systems/units for use
at small water facilities (3) the required system operation and maintenance (O&M) and operator skill
levels, and (4) the capital and O&M cost of the technology. The project also characterized the water in
the  distribution system and residuals generated by the treatment process. The types of data collected
included system operation, water quality, process residuals, and capital and O&M cost.

The three POE systems included one 30-gal/min (gpm) system installed in Purvine Hall, one 60-gpm
system installed in the Residence Hall, and one 60-gpm system installed in the College Union.  The 30-
gpm system had two parallel treatment trains, each consisting of two 18-in x  65-in fiber reinforced plastic
(FRP) vessels configured in series. Each vessel contained 5 ft3 of ArsenXnp (without underbedding), an
iron-modified/resin-based media manufactured by Purolite. Each 60-gpm system consisted of two 36-in
x 72-in FRP vessels configured in series.  The Residence Hall system contained 20 ftVvessel of ARM 200
media (without underbedding), an iron oxide/hydroxide media developed by Engelhard Corporation.
Because of an unexpected short run length, the lead vessel was first rebedded with ARM 300 (a newer
version of ARM 200 media) and then rebedded, along with the lag vessel, with E33-S.  E33-S is an iron-
based media developed by Lanxess, formerly Bayer AG. The College Union system contained 16 and
19.5 ft3 of Adsorbsia™ GTO™ (a titanium dioxide-based media) in the lead and lag vessels, respectively.
About 4 and 0.5 ft3 of Adsorbsia™ GTO™ media were washed from each vessel  during initial system
backwash, resulting in a large quantity of milky white effluent to be discharged to the sewer.

At the design flowrates of 30 and 60 gpm, the POE systems had a design hydraulic loading rate of 8.5
gpm/ft3 and a design empty bed contact time (EBCT) of 2.5 min/vessel.  Because  the systems were
operated on demand, actual flowrates were based on user consumption and could  vary significantly from
(but mostly lower than) the respective design flowrates. As such, actual hydraulic rates could be much
lowerthan the design value of 8.5 gpm/ft3 and actual EBCTs much longerthan the design value of 2.5
min.

Source water at OIT was supplied by two wells, i.e., Wells No. 1 and No. 4, with  Well No. 1 as the
primary well. After being chlorinated with a gas chlorine addition system, chlorinated water was stored
in a 250,000-gal aboveground  storage tank before being distributed to the campus. At each building,
water pressure was reduced to  50 to 76 lb/in2 (psi) by a pressure reducing valve before water was  allowed
to flow into the adsorption system. The inlet water contained 24.7 to 35.8 (ig/L of total arsenic, existing
predominately as soluble As(V). Iron and manganese concentrations were low, typically less than method
detection limits (MDLs) at 25 and 0.3 (ig/L, respectively.  pH values ranged from 7.3 to 8.5 and averaged
8.0.  The only competing anion in the inlet water was silica with concentrations ranging from 27.8 to 31.5
mg/L (as SiO2).

The performance evaluation studies for the ArsenXnp and ARM 200 systems began on December 12,
2005. Because of the issues with media backwashing, the Adsorbsia™ GTO™ system required
rebedding after initial media loading. Based on its pilot test results, Dow Chemical  performed media
backwashing in February 2006. The performance evaluation study for the Adsorbsia™ GTO™ system
did  not begin until February 17, 2006.  The ArsenXnp system operated for a total of  1,353 days without
media changeout. The ARM 200 system operated for 406 days.  Because of early arsenic breakthrough,
                                              IV

the lead vessel was rebedded with ARM 300 media on January 24, 2007, and then with E33-S media,
together with the lag vessel, on October 3, 2007. The Adsorbsia™ GTO™ system operated for a total of
1,286 days without media changeout.

Under on-demand conditions with varying system flowrates and water usage, E33-S media performed the
best, achieving approximately  50,000 bed volumes (BV) before reaching 10 ug/L arsenic in vessel
effluent. Adsorbsia™ GTO™ media was the next best performer, achieving 33,500 BV. ARM 200,
ARM 300, and ArsenXnp media had a rather common media life spanning from 13,940 to 16,200 BV.

Little or no pressure rise was observed across the adsorption vessels during the performance evaluation
studies, therefore, the POE systems did not require backwash. However, one backwash was performed
for all three systems on  May 16 or 17, 2006. Backwash wastewater and solids samples were collected
and analyzed for pH, total dissolved solids (TDS), total suspended solids (TSS), and/or metal contents.

Results of the distribution system water sampling indicated that arsenic concentrations decreased
significantly from an average of 29.2 ug/L before system startup to an average of 0.8 and 0.6 ug/L in
Purvine Hall and the College Union, respectively, after system startup. Distribution system water
samples in the Residence Hall  essentially mirrored ARM 200 system effluent. Post-baseline lead
concentrations ranged from <0.1 to 1.6  ug/L, which were below the action level of  15 ug/L. Post-
baseline copper concentrations ranged from 39.7 to 448 ug/L, which were below the action level of 1,300
Eight Kinetico POU units were installed either under a sink or inside a drinking water fountain in eight
different buildings on campus, but only three were monitored for their performance.  Each POU unit used
a single cartridge to house 600 mL of ARM 200 media for arsenic removal. A shut-off assembly and an
indicator on the outside of the filter head were used to measure and show the relative remaining cartridge
capacity, based on a maximum capacity of 500 gal. When 500 gal of water was processed, the shut-off
assembly was completely closed, preventing any more water from passing through the cartridge. About
1 1 months into the performance evaluation study, OIT began to install 40 AdEdge E33-S POU units and
replace the eight Kinetico units with AdEdge units.

Total arsenic concentrations were consistently reduced to below 1.0 ug/L by two Kinetico ARM 200
POU units after treating up to 740 gal of water. The third ARM 200 unit removed arsenic to <2. 1  ug/L
after treating 500 gal of water; its effluent concentration rose steadily to 6.0 ug/L after treating 1,000 gal
of water. Arsenic was consistently removed to the MDL by three AdEdge E33-S POU units after treating
500 gal of water. The E33-S unit could treat up to 3,000 gal of water.

The normalized capital cost was $l,862/gpm ($1.29/gpd) for the ArsenXnp system, $992/gpm ($0.69/gpd)
for the ARM 200 system, and $l,221/gpm ($0.85/gpd) for the Adsorbsia™ GTO™ system.  Based on the
actual annual water use rate, the unit capital cost was $10.77/1,000 gal for the ArsenXnp system,
$0.93/1,000 gal for the ARM 200 system, and $4.14/1,000 gal for the Adsorbsia™ GTO™ system. The
operation and maintenance (O&M) cost included the  cost for replacing media and the cost of labor to
operate the system. Media replacement is the major cost for an adsorptive media system.  Using vendor
provided quotes, a series of cost curves was constructed for all media tested (excluding ARM 300) in
terms of media cost per 1,000 gal of water treated as a function of the projected media run length to the  10
ug/L arsenic breakthrough.

The authors wish to extend their sincere appreciation to the Facilities Services Department at Oregon
Institute of Technology and Mr. Scott Keiffer, the Facility Operator, who monitored the treatment system
and collected samples from the treatment and distribution systems throughout the study. This
performance evaluation would not have been possible without their support and dedication.

                                    1.0 INTRODUCTION
1.1        Background

The Safe Drinking Water Act (SDWA) mandates that the U.S. Environmental Protection Agency (EPA)
identify and regulate drinking-water contaminants that may have adverse human health effects and that
are known or anticipated to occur in public water supply systems. In 1975, under the SDWA, EPA estab-
lished a maximum contaminant level (MCL) for arsenic (As) at 0.05 mg/L. Amended in 1996, the
SDWA required that EPA develop an arsenic research strategy and publish a proposal to revise the
arsenic MCL by January 2000. On January 18, 2001, EPA finalized the arsenic MCL at 0.01 mg/L (EPA,
2001).  To clarify the implementation of the original rule, EPA revised the rule text on March 25, 2003, to
express the MCL as 0.010 mg/L (10 (ig/L) (EPA, 2003). The final rule required all community and non-
transient, non-community water systems to comply with the new standard by January 23, 2006.

In October 2001, EPA announced an initiative for additional research and development of cost-effective
technologies to help small-community water systems (< 10,000 customers) meet the new arsenic standard
and to provide technical assistance to operators of small systems for reducing compliance cost. As part of
this Arsenic Rule Implementation Research Program, EPA's Office of Research and Development (ORD)
proposed a project to  conduct a series of full-scale, onsite demonstrations of arsenic removal
technologies, process modifications, and engineering approaches applicable to small systems. Shortly
thereafter, an announcement published in the Federal Register requested water utilities interested in
participating in Round 1 of this EPA-sponsored demonstration program to provide information on their
water systems. In June 2002, EPA selected 17 of the 115 candidate sites to host the demonstration
studies.

In September 2002, EPA solicited proposals from engineering firms and vendors for cost-effective arsenic
removal treatment technologies for the 17 host sites.  EPA received 70 technical proposals for the 17 host
sites, with each site receiving one to six proposals. In April 2003, an independent technical panel
reviewed the proposals and recommended to EPA the technologies they determined to be acceptable  for
the demonstration at each site. Because of funding limitations and other technical reasons, only  12 of the
17 sites were selected for the demonstration project.  Using the information provided by the review panel,
EPA, in cooperation with the host sites and the drinking-water programs of the respective states, selected
one technical proposal for each site.

In 2003, EPA initiated Round 2 arsenic technology demonstration projects that were partially funded with
Congressional add-on funding to the EPA budget. In June  2003, EPA selected 32 potential demonstration
sites, and the water system at Oregon Institute of Technology (OIT) in Klamath Falls, OR was one of
those selected.

In September 2003, EPA again solicited proposals from engineering firms and vendors for arsenic-
removal technologies. EPA received 148 technical proposals for the 32 host  sites, with each site
receiving two to eight proposals.  In April 2004, EPA convened another technical panel to review the
proposals and provide recommendations to EPA; the  number of proposals per site ranged from none  (for
two sites) to four. At the sites receiving at least one proposal, the final selection of the treatment
technology was made through a joint effort by EPA, the state regulators, and  the host site.  Since then,
four sites have withdrawn from the demonstration program, reducing the number of sites to 28. Three
point of entry (POE) adsorptive media (AM) systems and eight point of use (POU) AM units, all
manufactured by Kinetico, were selected in October 2004 for demonstration at the OIT facility.  The  three
POE systems separately contained ArsenXnp, ARM 200, and Adsorbsia™ GTO™ media manufactured by
Purolite, Engelhard Corporation, and Dow Chemical, respectively. About 11 months into the study,  OIT

-------
began to install 40 additional AdEdge POU AM units and replace the eight Kinetico units with AdEdge
units.

As of January 2010, 39 of the 40 systems were operational and the performance evaluation of all 39
systems was completed.

1.2        Treatment Technologies for Arsenic Removal

The technologies selected for the Round 1 and Round 2 demonstration host sites include 25 AM systems
(the OIT site has three AM systems), 13 coagulation/filtration (C/F) systems, two ion exchange (IX)
systems, 17 POU units (including nine under-the-sink reverse osmosis [RO]  units at the Sunset Ranch
Development site and eight AM units at the OIT site), and one system modification. Table 1-1
summarizes the locations, technologies, vendors, system flowrates, and key source water quality
parameters (including As, iron [Fe], and pH) at the 40 demonstration sites. An overview of the
technology selection and system design for the 12 Round 1 demonstration sites and the associated capital
costs is provided in two EPA reports (Wang et al., 2004; Chen et al., 2004), which are posted on the EPA
Web site at http://www.epa.gov/ORD/NRMRL/wswrd/dw/arsenic/index.html.

1.3     Project Objectives

The overall objective of the arsenic demonstration program is to conduct full-scale arsenic treatment
technology demonstration studies on the removal of arsenic from drinking-water supplies.  The  specific
objectives are to:

        •   Evaluate the performance of the arsenic removal technologies for use on small systems.

        •   Determine the required system operation and maintenance (O&M) and operator skill levels.

        •   Characterize process residuals produced by the technologies.

        •   Determine the capital and O&M costs of the technologies.

This report summarizes the performance of the POE AM systems and POU AM units at OIT in Klamath
Falls, OR, from December  12, 2005, through December 16, 2009.  The types of data collected include
system operation, water quality (both across the treatment train and in the distribution system), residuals,
and capital and O&M cost.

                            2.0 SUMMARY AND CONCLUSIONS
Based on the information collected from operation of the Kinetico POE/POU treatment systems/units at
Klamath Falls, OR from December 12, 2005 through August 26, 2009, the following summary and
conclusions are provided relating to the overall objectives of the treatment technology demonstration
study.

Performance of the arsenic removal technology for use on small systems:

        •   Under on-demand conditions with varying water flowrates and use rates, E33-S and
           Adsorbsia™ GTO™ media achieved a run length of 50,000 and 33,500 bed volumes (BV),
           respectively, before reaching 10 ug/L arsenic breakthrough.  ARM 200, ARM 300, and
           ArsenXnp media had shorter media life spanning from 13,940 to 16,200 BV.

        •   The ARM 200 POU units consistently removed arsenic to <6.0 (ig/L after treating up to
           1,000 gal of water.  The E33-S POU units  could treat up to 3,000 gal of water with arsenic
           concentrations below the MCL.

        •   The initial backwash after media loading required up to 115 BV of backwash water for
           Adsorbsia™ GTO™ media while ARM 200 and ArsenXnp media required only a few BV of
           backwash water.

        •   Media backwashing during prolonged system operation (up to 3 to 4 years) did not appear to
           be necessary.

        •   Arsenic concentrations in the distribution system (downstream from the treatment systems)
           appeared to mirror those in system effluent.  Post-baseline lead and copper levels were
           significantly below the respective action levels.

Required system O&M and operator skill levels:

        •   Under normal operation, the daily demand on the operator was typically 30 min to
           visually inspect the system and record operational parameters for each of the three
           POE systems.

        •   Daily operation of the system did not require additional skills beyond those
           necessary to operate the existing water supply equipment. OIT is classified by the
           State of Oregon as an "S" class water treatment system and the operator has a
           matching certificate.

Characteristics of residuals produced by the technology:

        •   Residuals produced by the operation of the treatment system included backwash
           wastewater and spent media.

        •   The POE systems were backwashed only once during close to four years of system
           operation. A total of 1,540-gal backwash wastewater was produced from the
           backwash event, which contained up to 91.6 g of solids.

-------
Capital and O&M cost of the technology:

       •   Using the system's rated capacity, the normalized cost was $l,862/gal/min (gpm)
           (or $1.29/gal/day [gpd]) for the Purvine Hall system, $992/gpm (or $0.69/gpd) for
           the Residence Hall system, and $l,221/gpm (or $0.85/gpd) for the College Union
           system.

       •   Media replacement is a major cost for operating an AM system. Among the four
           media with vendors'  quotes, the unit media cost is $300/ft3 for E33-S, $468/ft3 for
           ARM 200, $595/ft3 for ArsenXnp, and $678/ft3for Adsorbsia™ GTO™.

General Project Approach
Table 3-1 summarizes pre-demonstration activities and completion dates. Following the pre-
demonstration activities, the performance evaluation study of the POE/POU treatment systems/units
began on December 12, 2005 (evaluation of the Adsorbsia™ GTO™ system did not begin until February
17, 2006), and ended on December 16, 2009. Table 3-2 summarizes the types of data collected and
considered as part of the technology evaluation process.  The overall performance of the systems/units
was evaluated based on their abilities to consistently remove arsenic to below the MCL of 10 |og/L. This
was monitored through the collection of water samples across treatment trains, as described in a study
plan (Battelle, 2006). The reliability of the systems/units was evaluated by tracking unscheduled system
downtime and the frequency and extent of repair and replacement. The plant operator recorded
unscheduled downtime and repair information on a Repair and Maintenance Log Sheet.

O&M and operator skill requirements were assessed through quantitative data and qualitative
considerations, including the need for pre- and/or post-treatment, level of system automation, extent of
preventative maintenance activities, frequency of chemical and/or media handling and inventory, and
general knowledge needed for relevant chemical processes and related health and safety practices.
Staffing requirements for the system operation were recorded on an Operator Labor Hour Log Sheet.

The quantity of aqueous and solid residuals generated was estimated by tracking the volume of backwash
wastewater produced during each backwash cycle. Backwash wastewater was sampled and analyzed for
chemical characteristics.
The cost of the system was evaluated based on the capital cost per gpm (or gpd) of design capacity and
the O&M cost per 1,000 gal of water treated. This task required tracking the capital cost for equipment,

3.2
System O&M and Cost Data Collection
The plant operator performed daily, weekly, and monthly system O&M and data collection according to
instructions provided by the vendor and Battelle.  On a regular basis, the operator recorded POE system
operational data such as pressure, flowrate, and throughput readings (see Appendix A) on a System
Operation Log Sheet, checked the position of all manual valves, and conducted visual inspections to
ensure normal operation of the systems/units.  If any problem occurred, the operator contacted the
Battelle Study Lead, who determined if the vendor should be contacted for troubleshooting. The plant
operator recorded relevant information, including the problems encountered, course of actions taken,
materials and supplies used, and associated cost and labor incurred on the Repair and Maintenance Log
Sheet. On a regular basis, the  plant operator measured onsite temperature, pH, dissolved oxygen (DO),
oxidation-reduction potential (ORP), and residual chlorine, and recorded the data on an Onsite Water
Quality Parameters Log Sheet. Backwash data also were recorded on a Backwash Log Sheet.

The capital cost for the POE/POU arsenic removal systems/units consisted of the expenditure for
equipment, site engineering, and system installation.  The O&M cost consisted of the cost for media
replacement and labor. There were no electrical components associated with the POE systems. Labor
hours for various activities such as the routine system O&M, system troubleshooting and repair, and
demonstration-related work, were tracked using an Operator Labor Hour Record. The routine system
O&M included activities such  as completing field logs, ordering supplies, performing system inspections,
and others as recommended by the vendor. The labor for demonstration-related work, including activities
such as performing field measurements, collecting and shipping samples, and communicating with the
Battelle Study Lead and the vendor, was  recorded, but not used for cost analysis.

3.3        Sample Collection Procedures and Schedules

Three POE systems and eight POU units were initially installed for the demonstration study. One each
POE system was installed at the Purvine Hall, the Residence Hall, and the College Union. The Purvine
Hall houses a number of classrooms, laboratories, offices, and the Oregon Renewable Energy Center.
The Residence Hall provides domitory facilities for 250 students. The College Union houses a bookstore,
post office, campus dining, and offices for admissions, financial aid, information, and student affairs.

All three POE systems were monitored for their performance.  Samples were collected at the wellhead,
across the treatment plant, during adsorption vessel backwash, and from the distribution system.  Among
the eight POU units installed, only three located in the University Advancement building, Snell Hall, and
the Facility Service building were monitored for their performance. Performance of these units was
monitored by tracking arsenic concentrations in unit effluent.  Table 3-3 shows sampling schedules and
analytes measured during each sampling event.

Figures 3-1 to 3-4 present flow diagrams of the treatment systems, along with the analytes and schedules
for each sampling location.  Specific sampling requirements for analytical methods, sample volumes,
containers, preservation, and holding times are presented in Table 4-1 of the EPA-endorsed Quality
Assurance Project Plan (QAPP) (Battelle, 2004).  The procedure for arsenic speciation is described in
Appendix A of the  QAPP.

3.3.1       Source Water. During the initial site visit on October 27, 2004, one set of source water
samples was collected from Well No. 1 and speciated using an arsenic speciation kit (Section 3.4.1). The
samples were analyzed for detailed water quality analyses with analytes listed in Table 3-3. The  sample
tap was flushed for several minutes before sampling; special care was taken to avoid agitation, which
might cause unwanted oxidation.

3.3.2       Treatment Plant Water.  Samples were initially collected from the POE systems biweekly
on an eight-week cycle and from the POU units monthly.  Over the course of the study, the sampling
frequency decreased to monthly, bimonthly, and quarterly for the POE systems and to quarterly for the
POU units.

       •   Purvine Hall (Figure 3-1).  The system performance evaluation began on January 11, 2006.
           Speciation samples were collected during the first sampling event at the inlet (IN) and
           combined effluent (TT) locations. Afterwards, samples were collected bi-weekly for two
           eight-week cycles with speciation and other analytes analyzed at IN and TT at the beginning
           of the cycle and total arsenic analyzed at IN and after Vessels Bl, Al, B2, and A2 (TB1,
           TA1, TB2, TA2) for the next three bi-weekly sampling events (note that Vessels Bl  and B2
           were at the lead position).  Starting on May 9, 2006, samples were collected bi-weekly for six
           four-week cycles with a speciation event at IN and TT at the beginning of the cycle and total
           arsenic at IN, TB1, TA1, TB2, and TA2 during the other sampling event in each four-week
           cycle.  Samples were collected bi-monthly from January 10, 2007, through May 2, 2007, at
           the five locations for total arsenic. On August 1, 2007, samples were collected quarterly until
           August 26, 2009.

       •   Residence Hall (Figure 3-2). The first samples were collected on January 11, 2006, at IN
           and after Vessels B and A (TB and TA) (note that Vessel B was at the lead position).
           Afterwards, samples were collected bi-weekly at all three locations for two eight-week cycles
           with speciation at the beginning of the cycle and total arsenic during the remaining three bi-
           weekly samplings events.  Starting on May 9, 2006, samples were collected bi-weekly for six
           four-week cycles with a speciation event at the beginning of the cycle and total arsenic during

           bi-monthly for total arsenic only leading up to rebedding with ARM 300 media on January
           24, 2007.  Following rebedding, samples were collected monthly until June 1, 2007.  On July
           11, 2007, the system was placed in bypass until rebedding with E33-S on October 3, 2007.
           The system was sampled quarterly between December 18, 2007, and August 26, 2009.

       •   College Union (Figure 3-3). On March 1, 2006, samples were collected at IN, TA, and TB
           for total arsenic (note that Vessel A was in the lead position). After the first sampling event,
           samples were collected bi-weekly  on an eight-week cycle with speciation performed at all
           locations at the beginning of the cycle and total arsenic during the remaining three bi-weekly
           sampling events.  Starting on May 9, 2006, samples were collected bi-weekly for six four-
           week cycles with speciation performed at all locations at the beginning of the cycle and total
           arsenic during the other sampling events. Samples were collected bi-monthly from January 1,
           2007 through May 5, 2007. On August 1, 2007, samples were collected quarterly until
           August 26, 2009.

For all sampling events, pH, temperature, DO, and ORP were measured onsite using a VWR SymPhony
handheld meter. Free chlorine residuals also were measured onsite using a Hach handheld colorimeter.
DO and ORP were not measured from February 13, 2008, through August 26, 2009.

Three of the eight POU units located in the University Advancement building (POU 1), Snell Hall (POU
2), and the Facility Services building (POU 3)  were designated for monthly sampling from January 12,
2006, through June 6, 2006 and quarterly from August 1, 2007, through December 16, 2009. On

-------
February 13, 2008, the POU unit at Snell Hall was moved to Cornett Hall.  Samples were collected after
cartridge filters for total arsenic analyses. Total flow measurements for the three POU units were
recorded through Kent meters. On November 15, 2007, May 25, 2008, and August 15, 2008, the three
Kinetico POU units were replaced with AdEdge POU units loaded with E33-S.

3.3.3       Backwash Wastewater and Solids.  During the performance evaluation study, the three
POE systems were backwashed once on May 16 or 17, 2006. One backwash wastewater sample was
collected from each adsorption vessel. The procedure involved diverting a portion of backwash
wastewater from the backwash discharge line to a 32-gal plastic container over the duration of the
backwash for each vessel. After the content in the container had been thoroughly mixed, a composite
sample was collected and/or filtered onsite with 0.45-(im disc filters.  Analytes for the backwash
wastewater samples are listed in Table 3-3.

The content in the 32-gal plastic container was allowed to settle and the supernatant was carefully
siphoned using a piece of plastic tubing to avoid agitation of settled solids in the container.  The
remaining solids/water mixture was then transferred to a 1-gal plastic jar.  After solids in the jar were
settled and the supernatant was carefully decanted, one aliquot of the  solids/water mixture was air dried
before being acid-digested and analyzed for the metals listed in Table 3-3.

3.3.4       Distribution System Water. Water samples were collected from the distribution system to
determine the impact of the three POE arsenic treatment systems on its water chemistry, specifically, the
arsenic, lead and copper levels. Prior to system startup, four monthly baseline distribution water samples
were collected from three locations within the distribution system from July to September 2005.
Following system startup, distribution system sampling continued on  a monthly basis at the same three
locations from January 25, 2006 to April 4, 2007. Analytes for the distribution system sampling are
presented in Table 3-3.

The three distribution system sampling locations were at Purvine Hall, the Residence Hall, and the
College Union. These three locations were part of OIT's historic sampling network for the Lead and
Copper Rule (LCR).  The system operator collected the first draw distribution system samples following
an instruction sheet developed by Battelle in accordance with the Lead and Copper Monitoring and
Reporting Guidance for Public Water Systems (EPA, 2002). The operator recorded the date and time of
last water use before sampling and the date and time of sample collection for calculation of the stagnation
time.  All samples were collected from a cold water faucet that had not been used for at least 6 hr to
ensure that stagnant water was sampled. The samples were analyzed  for the analytes listed in  Table 3-3.
Arsenic speciation was not performed for the distribution system water samples.

3.3.5       Residual Solids. Three ARM 200 spent media samples were collected from the lead vessel
(Tank B) during media changeout at the Residence Hall on January 24, 2007. Spent media was sampled
from the top (i.e.,  0 to 4 in into the bed), middle (i.e., 22 to 26 in), and bottom (i.e., 35 to 39 in) of the
media bed using a 6.5-horsepower (hp) wet/dry shop vac that had been thoroughly cleaned and
disinfected before sampling. The media collected from each target layer was transferred from the shop
vac to a clean 5-gal bucket and mixed carefully with a small garden spade. A composite sample from
each layer was collected into a wide-mouth, 1-gal plastic container and sent to Battelle for analysis.
Metal analyses were conducted on air dried and acid digested samples (see analytes in Table 3-3) and
toxicity characteristic leaching procedure (TCLP) tests were conducted on unprocessed samples following
the protocol described in the QAPP (Battelle, 2004).

3.4        Sampling Logistics

All sampling logistics, including arsenic speciation kit preparation, sample cooler preparation, and sample
shipping and handling are discussed below.

3.4.1       Preparation of Arsenic Speciation Kits. The arsenic field speciation method uses an anion
exchange resin column to separate soluble arsenic species, i.e., As(V) and As(III) (Edwards et al., 1998).
Resin columns were prepared in batches at Battelle laboratories in accordance with the procedures
detailed in Appendix A of the QAPP (Battelle, 2004).

3.4.2       Preparation of Sampling Coolers. For each sampling event, a sample cooler was prepared
with the appropriate number and type of sample bottles, disc filters, and/or speciation kits.  All sample
bottles were new and contained appropriate preservatives. Each sample bottle was affixed with a pre-
printed, colored-coded, waterproof label consisting of the sample identification (ID), date and time of
sample collection, collector's name, site location, sample destination, analysis required, and preservative.
The sample ID consisted of a two-letter code for the demonstration site, the sampling date,  a two-letter
code for a specific sampling location, and a one-letter code for designating the arsenic speciation bottle (if
necessary). The sampling locations at the treatment plant were color-coded for easy identification. The
labeled bottles for each sampling location were placed in separate zip loc bags (each corresponding to a
specific sample location) and packed in the cooler. When needed, the sample cooler also included bottles
for the distribution system sampling.

In addition, all sampling- and shipping-related materials, such as disposable gloves, sampling instructions,
chain-of-custody forms, prepaid/addressed FedEx air bills, and bubble wrap, were placed in each cooler.
The chain-of-custody forms and airbills were complete except for the operator's signature and the sample
dates and times.  After preparation, the sample cooler was sent to the site via FedEx for the following
week's sampling event.

3.4.3       Sample Shipping and Handling.  After sample collection, samples for offsite analyses were
packed carefully in the original coolers with wet ice and shipped to Battelle. Upon receipt, the sample
custodian checked sample IDs against the chain-of-custody forms and verified that all samples indicated
on the forms were included and intact. The Battelle Study Lead addressed discrepancies noted by the
sample custodian with the plant operator. The  shipment and receipt of all coolers by Battelle were
recorded on a cooler tracking log.

Samples for metal analyses were stored and analyzed at Battelie's Inductively Coupled Plasma-Mass
Spectrometry (ICP-MS) laboratory. Samples for other water quality analyses were packed  in  separate
coolers and picked up by couriers from American Analytical Laboratories (AAL) in Columbus, OH and
Belmont Labs in Englewood, OH,  both of which were under contract with Battelle for this demonstration
study.  The chain-of-custody forms remained with the samples from the time of preparation through
analysis and final disposition. All  samples were archived by the appropriate laboratories for the
respective duration of the required hold time, and disposed of properly thereafter.

3.5        Analytical Procedures

The analytical procedures described in Section 4.0 of the QAPP (Battelle, 2004) were followed by
Batte lie's ICP-MS laboratory, AAL, and Belmont Labs.  Laboratory quality assurance/quality control
(QA/QC) of all methods followed the prescribed guidelines. Data quality in terms of precision, accuracy,
method detection limits (MDLs), and completeness met the criteria established in the QAPP (i.e., relative
percent difference [RPD] of 20%, percent recovery of 80 to 120%, and completeness of 80%). The QA data
                                               17

-------
associated with each analyte will be presented and evaluated in a QA/QC Summary Report to be prepared
under separate cover upon completion of the Arsenic Demonstration Project.

Field measurements of pH, temperature, DO, and ORP were conducted by the plant operator using a
handheld field meter, which was calibrated for pH and DO prior to use following the procedures provided
in the user's manual.  The ORP probe also was checked for accuracy by measuring the ORP of a standard
solution and comparing it to the expected value.  The plant operator collected a water sample in a clean,
plastic beaker and placed the probe in the beaker until a stable value was obtained. The plant operator also
performed free and total chlorine measurements  using Hach chlorine test kits following the user's  manual.

                              4.0 RESULTS AND DISCUSSION
4.1
Site Description
4.1.1       Pre-existing Facility. The OIT-Klamath Falls campus (Figure 4-1) is located just east of the
Cascade Mountains in southern Oregon. The non-transient, non-community water system supplies water
to a population of 3,315 via 15 connections to individual buildings. The average daily use for the year of
2003 to 2004 was 167,000 gpd and the peak daily use was 350,000 gpd. A large quantity of water was
used for outdoor irrigation and landscaping due to the dry climate. Only 20,000 to 60,000 gpd was used
by facilities such as dormitories, classrooms, laboratories, and offices for drinking, sanitary, and
teaching/research purposes.

Source water is groundwater supplied by two wells, Wells No. 1 and No. 4, located on the east side of the
campus. Well No. 1 is the primary supply well and Well No. 4 is a backup well. Figure 4-2 shows the
Well No. 1 pump house. Well No. 1 was drilled to a depth of 1,205 ft below ground surface (bgs) with a
screen interval from 455 ft to 1,205 ft bgs.  The well casings are  8-in in diameter from the surface to 685
ft bgs and 6-in in diameter from 685 ft to 1,205 ft bgs. Well No. 1 is equipped with a 60-hp closed line
shaft turbine pump rated for 300 gpm at a total dynamic head (TDH) of 600 ft of water or 260 lb/in2 (psi).
Well No. 4 has a total depth of 1,224 ft with a screen interval from 300 ft to 1,221 ft bgs.  The well
casings are 12-in in diameter from the surface to  732 ft bgs, 10-in in diameter from 732 ft to 1,037 ft bgs,
and 8-in in diameter from 1,037 ft to 1,224 ft bgs. It is equipped with a 75-hp submersible pump rated for
250 gpm at a TDH of 530 ft of water or 230 psi.  The static water level was measured at 449 ft bgs in
Well No. 1 and 315 ft bgs in Well No. 4. Well No. 1 typically operates approximately 2.5 hr/day in
winter and 12 hr/day in summer to meet the water demand.

The existing water treatment includes wellhead chlorination using chlorine gas to maintain a free chlorine
residual level of 0.25 to 0.35 mg/L (as C12).  Figures 4-3 and 4-4 show an existing chlorine gas storage
unit and a chlorine addition system for Well No.  1.  The chlorinated water is stored in a 250,000-gal
aboveground storage tank located near the pump  house (Figure 4-5) before being distributed to the
campus.

4.1.2       Distribution System.  The distribution system at OIT supplies water to 13 buildings on the
campus.  Chlorinated water from the Well No. 1 pump house flows to the 250,000 gal storage tank before
entering the distribution system. Chlorinated water from the Well No. 4 pump house feeds directly into
the distribution system with excess water going to the storage tank. The distribution piping consists of
10-in asbestos cement, 8-in polyvinyl chloride (PVC), and 6-in ductile iron piping. The size and material
of the plumbing as well as the system pressure at each building inlet are presented in Table 4-1. Once
entering a building, the system pressure is reduced to 50 to 76 psi by a pressure reducing valve. Figure 4-
6 shows a photograph of a pressure reducing valve at one building inlet.
                  Figure 4-6. Pressure Reducing Valve at a Building Entry Point
The routine distribution system sampling at OIT included coliform (once a month), lead and copper (once
every three years), and asbestos (once every nine years). In December 2004, OIT conducted lead and
copper sampling at 20 locations. The 90th percentile results were below the respective action levels of 15
and 1,300 ug/L. As part of the EPA demonstration study, one location each in Purvine Hall, the
Residence Hall, and the College Union was selected for monthly distribution sampling before and after
installation of the POE treatment systems.  These locations are part of OIT's historic LCR sampling
network. In addition, OIT conducted routine sampling at the distribution system entry points of Well No.
1 and Well No. 4 for arsenic, inorganic chemicals (IOC), nitrate, nitrite, volatile organic compounds
(VOCs), synthetic organic compounds (SOCs), and disinfection byproducts (DBP) from yearly to once
every nine years as directed by the Oregon DHS DWP.

4.1.3       Source Water Quality.  Source water samples were collected from Well No. 1 on
October 27, 2004, and analyzed for the analytes shown in Table 3-3. The analytical results are presented
in Table 4-2 and compared to the data (for both Wells No.  1 and No. 4) provided by OIT to EPA for the
demonstration site selection and the data independently collected by Kinetico.  Based on the data
presented in Table 4-2, water quality of the two wells was similar.

Arsenic. Total arsenic concentrations in source water (from both wells) ranged from 27.0 to 36.0 (ig/L.
Based on the October 27, 2004, speciation results, out of 32.8 |o,g/L of total arsenic, 32.5 |o,g/L existed as
As(V). Although pre-chlorination was not required, the existing wellhead chlorination system continued
to be used to disinfect water throughout the study period.

Iron and Manganese. Iron and manganese concentrations in source water were low, typically less than
their MDLs of 25 and 0.1 |o,g/L, respectively.  In general, AM technologies are best suited to water with
                                                23

-------
low iron levels (i.e., less than 300 |o,g/L, which is the secondary maximum contaminant level [SMCL] for
iron).

pH.  The pH of raw water ranged from 7.6 to 8.0. Typically, the target pH range for the use of AM for
arsenic removal is between 5.5 to 8.5. A pH value of 7.6 to 8.0 is within this range; therefore, pH
adjustment was not included for the arsenic treatment system.

Competing Anions. Arsenic adsorption could be influenced by the presence of competing anions such as
silica and phosphate.  Analysis of source water indicated silica levels at 30.3 to 34.2 mg/L (as SiO2) and
orthophosphate levels below 0.5 mg/L (as PO4).  Concentrations of these anions were monitored on a
regular basis during the system performance evaluation.

Other Water Quality Parameters. Nitrate was measured between 0.6 and 0.8 mg/L (as N).  Nitrite,
ammonia, and fluoride were either below or close to their respective detection limits.

Table 4-3 presents historical treated water quality data from July 2001 through August 2005 obtained
from the Oregon DHS DWP. These treated water quality data were similar to the source water quality
data presented in Table 4-2. Total arsenic concentrations of the treated water ranged from 27 to 38 |o,g/L.
No arsenic speciation data were available.

Treatment Process Description
4.2.1       POE/POU Approaches.  Kinetico originally proposed a centralized treatment system at the
wellhead.  This approach was replaced with one using three smaller POE systems during the January 19,
2005, project planning meeting attended by OIT, Kinetico, EPA, and the Oregon DHS DWP. The POE
approach was selected because (1) a POE system can be placed in an existing maintenance room in each
building, thus eliminating the need for a new treatment building to house a wellhead treatment system and
(2) a POE system only treats the water entering the building, not the water for irrigation and landscaping,
thus reducing the amount of water treated and the associated operational cost. Water usage and flowrate
information was not available during the system sizing and design phase of the project due to the lack of
water meters in any of the buildings. Weber Elliot Engineers and Kinetico provided flow estimates based
on fixture counts in each building. Table 4-3 summarizes these estimates.

To more accurately estimate flowrates, a portable ultrasonic flow meter (Greyline Instruments, Inc.) was
used for 24-hr real-time flow measurements in two buildings: the Residence Hall from March 28 to 29,
2005 (Figure 4-7) and Purvine Hall from April 4 to 5, 2005 (Figure 4-8). Flow measurements were made
by strapping the ultrasonic flow meter onto the entry piping in each building.  The measurements
indicated that the total water usage at the Residence Hall was 14,456 gal with flowrates ranging from 0 to
156 gpm and averaging 19.4 gpm. The total water usage at Purvine Hall was 2,073 gal with flowrates
ranging from 0 to 62 gpm and averaging 8.4 gpm. Although these one-time measurements might not be
                                              24

representative of the year-long use, they appeared to be more accurate than the estimates based on
building fixture counts provided by Weber Elliot Engineers and Kinetico. A decision was then made by
EPA to install three POE AM systems and eight POU AM units for this demonstration study. The size
and location of the POE systems are listed as follows:

       •   A 30-gpm ArsenXnp system in Purvine Hall
       •   A 60-gpm ARM 200 system in the Residence Hall
       •   A 60-gpm Adsorbsia™ GTO™ system in the College Union

Due to early arsenic breakthrough, ARM 200 media was changed out on two occasions with ARM 300
and E33-S. The eight Kinetico POU units were replaced with AdEdge POU units loaded with E33-S;
another 40 AdEdge POU units also were installed in various campus buildings.

4.2.2       Adsorptive Media. The three POE systems initially employed one of three adsorptive
media: (1) ArsenXnp, an iron-modified/resin-based media manufactured by Purolite; (2) ARM 200
(Ultrasorb-F as branded by Kinetico), an iron-based media manufactured by Engelhard Corporation; and
(3) Adsorbsia™ GTO™, a titanium dioxide-based media manufactured by Dow Chemical. The system
loaded with ARM 200 was rebedded with ARM 300, an iron-based media also manufactured by
Engelhard Corporation, and then E33-S, an iron-based media manufactured by Lanxess (formerly Bayer
AG).  The eight POU units used ARM 200 media initially, but were replaced with AdEdge POU units
loaded with E33-S.  All adsorptive media are listed by NSF International (NSF) under Standard 61 for use
in drinking water, and their physical and chemical properties are summarized in Table 4-4. More detailed
descriptions of the media are provided below.

ArsenXnp. ArsenXnp media was developed by SolmeteX, Inc. and manufactured and distributed by
Purolite, Inc. under an exclusive license from Lehigh University.  It has a base structure of macro-porous
polystyrene/divinylbenzene impregnated with nanoparticles containing hydrous iron oxide functional
groups.  The media adsorbs both As(V) and As(III), with a higher capacity for As(V). It also removes
other contaminants, such as vanadium, molybdenum, chromium, and uranium. The media has good
mechanical strength and attrition resistance and does not generate fines during long-term vessel operation.
The media can handle water with a pH range from 4 to 9.  ArsenXnp media can be regenerated multiple
times with a dilute caustic NaOH/NaCl solution. However, media regeneration and reuse were not
planned for the OIT site.

ARM 200 and ARM 300 Media. Developed by Engelhard Corporation, ARM 200 media is a granular
iron oxide/hydroxide media designed to remove dissolved arsenic from drinking water supplies via
adsorption onto its surface. Kinetico marketed the media as Ultrasorb-F. ARM 200 adsorbs both
As(V) and As(III) in a pH range from 5 to 9.  The media is less effective for As(III) and at the upper
                                              27

end of the pH range. ARM 300 media is similar to ARM 200, but has a lighter bulk density (i.e., 35 to
40 vs. 45 to 50 lb/ft3) and somewhat broader size distribution (12 x 50 vs. 12 x 40 U.S. standard mesh).

Adsorbsia™ GTO™ Media. Adsorbsia™ GTO™ is a white, free-flowing granular titanium oxide-based
media manufactured by Dow Chemical. The media is capable of adsorbing both As(V) and As(III), with
a higher capacity for As(V). It adsorbs arsenic at a pH range of 6.5 to 8.5, but the adsorption is less
effective at the upper end of the range. According to the vender, the media's capacity for arsenic may be
independent of anion ions such as sulfate, phosphate, and vanadium.  However, the presence of silica can
reduce arsenic removal.  Source water at OIT contained 30.3 to 34.2 mg/L of silica (as SiO2); its impact
on arsenic adsorption was closely monitored. Adsorbsia™ GTO™ cannot be regenerated.

E33-S. Bayoxide E33-S media (branded as AD-33 by AdEdge), is an iron-based AM developed by
Lanxess (formerly Bayer AG) for the removal of arsenic from drinking water supplies. The media is
available in both granular and pelletized forms and delivered in a dry, crystalline form. The pelletized
media is 25% denser than its granular counterpart (i.e., 35 vs. 28 lb/ft3).

4.2.3       Treatment Process Description

4.2.3.1     Key Process Steps/System Components.  The major process steps and system components of
the water system at OIT are discussed as follows:


       •   Intake. Raw water was supplied by two wells, with Well No. 1 being the primary well and
          Well No. 4 being the backup well. Based on the water meter at the Well No.  1 pump head,
          the total water consumption during the first year of performance evaluation study was
          approximately 55,085,000 gal,  compared to the 8,184,000 gal of water treated by the three
          POE systems combined.  The majority of water consumption on campus was for irrigation.

       •   Prechlorination. The pre-existing wellhead chlorination system was used to disinfect  water.
          Gas chlorine was used to maintain a target free chlorine residual level of 0.35 to 0.4 mg/L (as
          C12). Chlorine gas cylinders (150 Ib) were kept in a room partitioned from the rest of the Well
           1 pump house.  The chlorine gas feed rate was  regulated at 2.4 Ib/day using a panel-mounted
          VI00 chlorinator (Wallace & Tiernan). A dual-cylinder scale was used to monitor the
          chlorine gas consumption. Chlorine gas was injected to a side stream where an injector was
          used to create a venturi effect to mix chlorine gas with carrier water.  Chlorinated water then
          was blended with source water prior to entering a 250,000-gal aboveground storage tank.

       •   Water storage. Chlorinated water was temporarily stored in the existing 250,000-gal
          aboveground storage tank located on a hill near the Well No. 1 pump house before being
          distributed to the campus.

       •   Distribution main and entry piping.  The distribution main delivered water by gravity from
          the storage tank to the 13 buildings on campus. Upon entering a building, the system pressure
          was reduced to between 50 to 76 psi using pressure reducing valves (see Table 4-1). The inlet
          piping to Purvine Hall, the Residence Hall, and the College Union consisted of 3-in copper, 4-
          in copper, and 3-in copper, respectively, which was plumbed separately to the 30- gpm
          ArsenXnp, 60 gpm ARM 200, and 60-gpm Adsorbsia™ GTO™ systems. Figure 4-9 shows
          the inlet and exit piping to and  from the 30-gpm ArsenXnp system at Purvine Hall.
                                              28

POE/POU adsorptive media systems.  The POE treatment systems and POU units are
discussed in detail in Sections 4.2.3.2 and 4.2.3.3, respectively.

Hydropneumatic tank. A 132-gal hydropneumatic tank (Amtrol Model WX-450-C) was
installed downstream of each POE treatment system to meet demand and provide water for
backwashing. The 24-in x 865/8-in tank had a steel shell coated with blue enamel paint on top
of red oxide primer and an inner bladder constructed of heavy duty butyl rubber.  The tank
was pre-charged at the factory with air at 25 psi, a pressure lower than the inlet piping
pressure (i.e., the pressure after the respective pressure reducing valve).
Building distribution system.  The effluent piping from each POE system and
hydropneumatic tank was tied into the exit piping to provide treated water to the distribution
system inside each building.
                                   29

-------
4.2.3.2     POE Treatment Systems. All three POE arsenic removal systems are fixed-bed adsorption
systems, each consisting of one or two parallel treatment trains. Each treatment train consisted of two
adsorption vessels configured in series.

For series operation, the media in the lead vessel is removed and disposed of when it completely exhausts
its capacity or when the effluent from the lag vessel reaches  10 (ig/L of arsenic. Upon rebedding, the lead
vessel is switched to the lag position and the lag vessel is switched to the lead position. In general, the
series operation better utilizes the media capacity when compared to parallel operation because the lead
vessel may be allowed to exhaust completely prior to changeout.

When comparing the performance of the lead vessel (series operation) with that of two smaller in-parallel
vessels of a similarly-sized system (parallel operation), the number of BV treated by the system is
calculated based on the media volume in the lead vessel for the series operation and in both vessels for the
parallel operation.  The calculation does not use the media volume in the lead and lag vessels because this
approach considers the two vessels as one large vessel, which has twice as much media than the in-
parallel system.  The media volume in the lead vessel  is equal to the  sum of the media volume  in each of
the two vessels in parallel; the flow through the lead vessel is equal to the sum of the flow through each of
the two vessels in parallel; and the empty bed contact time (EBCT) in the lead vessel is the same as the
EBCT in each of the two vessels in parallel. BV following the  lag vessel were calculated based on the
combined media volume in both the lead and lag vessels.

ArsenX"p System. The ArsenXnp system installed in Purvine Hall had two parallel treatment trains, each
consisting of two pressure vessels configured in series. The process  equipment included four 18-in x 65-
in vessels and associated piping/valves, sample ports,  and pressure and flow instrumentation.  Rated at
150 psi working pressure, the pressure vessels featured a fiber reinforced plastic (FRP) outer shell and
polyethylene inner shell. Each vessel had a 6-in top and bottom flange opening and was equipped with a
diffuser-style upper distributor and a hub and lateral-style lower distributor.

The system performance was monitored by inlet and outlet pressure, pressure differential across each
vessel, treated water flowrate and volume through each train, and wastewater flowrate and volume during
backwash. The flowrate was monitored through an inline vertical rotameter with a polysulphone tube
housing. The volume of treated water or backwash  wastewater was measured using  an Amco Bronze
water meter (Model C-700-1.5). The system also featured schedule 80 PVC solvent bonded plumbing,
valves, and sampling ports.  The wall-mounted, pre-plumed plumbing was l!/2-in in diameter, which inter-
connected various system components. The piping  size at the tie-in point to the water inlet, outlet, and
sewer were 3, 3, and l!/2-in, respectively. Figure 4-10 shows the wall-mounted plumbing and pressure
and flow instrumentation.

The treatment system was an on-demand system and the flowrate and volume of water treated  were based
on user consumption. Each treatment train was equipped with a 15-gpm flow-limiting device to prevent
overrun. Thus, actual flowrates through each treatment train could range from 0 to 15 gpm based on
demand. The system was manually operated and there was no electrical connection associated with the
system. All flow meters and pressure gauges were mechanical  and all valves were manual.

Table 4-5  presents the system's design specifications.  Each tank was filled with 5 ft3 of ArsenXnp media
without underbedding support.  At the design flowrate of 30 gpm, it yielded a hydraulic loading rate of
8.5 gpm/ft2 and an EBCT of 2.5 min/vessel. However, actual hydraulic loading rates and EBCTs could
vary significantly because this was an on-demand system. The working capacity as projected by the
vendor was 52,750 BV, which is equivalent to 3,945,700 gal of water treated (1 BV = 5 ft3 = 37.4
gal/train or 74.8 gal for both trains). Based on a daily use rate of 2,000 gal from the  24-hr real-time flow
measurement performed on April 4 and 5, 2005 (see section 4.1), arsenic breakthrough at 10 ug/L
                                              30

following the lead vessels would occur after 65 months of system operation. During the system
performance evaluation study, the vessels were not rebedded as arsenic concentrations from the lag
vessels were <1.0 (ig/L.

Media backwash was an entirely manual process, involving physically opening and closing 2-in ball
valves. The vendor recommended that the treatment system be backwashed on a regular basis to remove
particulate accumulating in the media beds.  Backwash can be initiated when the differential pressure
(Ap) of any tank is 10 psi greater than that of a clean bed, after processing 10,000 BV of water, or after 60
days of operation. Each train in parallel can be backwashed independently or together. A manual valve
on the treated water line of each train (HV-7 for Train 1 and HV-20 for Train 2) was closed to isolate the
train for backwash; the other train continued to treat water and meet the demand along with the
hydropneumatic tank. Further, only one vessel in a train was backwashed at a time while the other vessel
in that train continued to treat water. The recommended backwash flowrate was  12 gpm, equivalent to a
hydraulic loading rate of 6.8 gpm/ft2. The backwash flowrate was monitored through the rotameter on the
wastewater outlet and adjusted using the metering valve on the wastewater discharge line. The flowrate
should be reduced if full-sized media granules were observed to escape the vessels. At a recommended
                                              31

backwash duration of 12 min for each vessel, approximately 144 gal of backwash wastewater would be
produced during each vessel backwash. A total of 576 gal of wastewater would be discharged to the

backwashedonce.

ARM 200 System. The ARM 200 system installed in the Residence Hall consisted of two 36-in x 72-in
vessels configured in series. Each vessel had a 6-in top and a 6-in bottom flange opening and was
equipped with a diffuser-style upper distributor and a hub and lateral-style lower distributor. The pressure
vessels were constructed of FRP and rated at 150 psi working pressure. The vessels were bolted to the
concrete floor. The piping size was 2-in within the system, 4-in at the system inlet and outlet tie-ins, and
2-in at the tie-in to the sewer. Similar to the ArsenXnp system, flowrates were monitored through inline
vertical rotameters and volumes of treated water and backwash wastewater were measured using Amco
Bronze water meters (Model C-700-2).  Figure 4-11  presents a photograph of the ARM 200 system.
                                              32

-------
                        Figure 4-11. ARM 200 System in Residence Hall
Table 4-6 presents key design features of the system. At the start of the study, each vessel was loaded
with 20 ft3 of ARM 200 media with no underbedding media support. The system was operated on-
demand with a minimum combined EBCT of 2.5 min and a maximum hydraulic loading rate of
8.5 gpm/ft2, both based on a design flowrate of 60 gpm. Switching of the lead and lag vessel positions
was controlled by a series of 2-in PVC ball valves.

The working capacity estimated by the vendor was 62,600 BV (or approximately 9,365,000 gal of water
[1 BV = 20 ft3 = 149.6 gal in lead vessel]).  Based on a daily use rate of 15,000 gal (from the 24-hr real
time flow measurement performed prior to the demonstration study [see section 4.2]), arsenic
breakthrough at 10 (ig/L following the lead vessel would occur after approximately 21 months of system
operation.

Due to unexpectedly rapid arsenic breakthrough from the adsorption vessels, ARM 200 media in the lead
vessel was rebedded with ARM 300 and the newly rebedded lead vessel was placed in the lag position.
Both the lead and lag vessel were rebedded with E33-S media due to a short run length again. The short
run length observed is discussed in detail in Section 4.5.2.2.

Manual backwash was recommended by the vendor to remove particulate using water in the
hydropneumatic tank. The backwash triggers were the same as those used by the ArsenXnp system. Only
one vessel was backwashed at a time while the other vessel continued to treat water used for backwash.
The recommended backwash flowrate was 50 gpm (or 7.0 gpm/ft2) and the recommended backwash
duration was 12 min for each vessel.  Therefore, approximately 600 gal of backwash wastewater would be
                                             33

Adsorbsia™ GTO™ System. The 60-gpm system at the College Union was designed and built in the
same fashion as the system in the Residence Hall.  The only difference was that it was used to evaluate a
different type of media (i.e., Adsorbsia™ GTO™). Based on the vendor-estimated working capacity and
a daily use rate of 15,000 gal, the media would last for 20 months, after treating approximately 8,998,400
gal of water (1 BV = 20 ft3 = 149.6 gal in the lead vessel). The system was backwashed in a similar
                                             34

manner as the 60-gpm ARM 200 system at the Residence Hall. Table 4-6 summarizes the system design
specifications.  Figure 4-12 presents a photograph of the system.

4.2.3.3     POU Units.  Each Kinetico POU unit used a single cartridge to house 600 mL of ARM 200
media for arsenic removal. The cartridge housing had exterior dimensions of 70 mm x 320 mm and %-in
female National Pipe Thread (NPT) threads for direct connections to an incoming cold water line and an
exit line.  Treated water was delivered from the exit line to a separately installed faucet. The POU units
were installed either under a sink or inside a drinking water fountain as shown in Figure 4-13.

As untreated water flowed into the feed water inlet, it was allowed to past a turbine, which was connected
to a gear to gradually close a measured shut-off assembly.  An indicator on the outside of the filter head
showed the relative remaining cartridge capacity, based on a maximum capacity of 500 gal. When 500
gal of water was processed, the measured shut-off assembly was completely closed, preventing any more
water from passing through the cartridge. Eight POU systems were installed in eight buildings on campus
as summarized in Table 4-7.

About 11 months into the performance evaluation study, OIT began to replace the Kinetico ARM 200
POU units with AdEdge E33-S POU units.  On November 15, 2007, May 25, 2008, and August 15, 2008,
AdEdge POU units were installed at the University Advancement, Cornett Hall, and the Facility Services
building,  respectively.  Overall, OIT replaced the eight Kinetico units with AdEdge units and installed 40
additional units.

The AdEdge POU units were comprised of a polypropylene housing. They had a 3/s-in inlet and a %-in
outlet.  The approximate flowrate with a system inlet pressure of 60 psi was 1 gpm. The working
pressure ranged from 20 to 125 psi. The unit had a height of 13 in and a diameter of 6.75 in.  Figure 4-14
shows the AdEdge housing and filter cartridge. Table 4-8 summarizes design specifications of the
Kinetico and AdEdge POU units.

4.3.1       System Permitting. Engineering plans for the system permit application were prepared by
Weber Elliott Engineers, a Kinetico subcontractor (also serving as the engineer for OIT) located in
Eugene, OR.  The plans included diagrams and specifications of the three POE systems and eight POU
units, as well as drawings detailing the connections of the new  systems/units to the tie-ins in each
building. The engineering package was certified by a Professional Engineer registered in the State of
Oregon and submitted to Oregon DHS for review and approval on October  13, 2005.  The permit was
issued by Oregon DHS on October 31, 2005, and was received by Battelle on November 1, 2005.

4.3.2       Building Construction. The three POE systems were placed into the existing mechanical or
storage room of each building. Necessary arrangements were made to accommodate the treatment
systems and pipe/conduit supports were hung from the ceiling and/or attached to the walls. Plumbing was
modified to provide connections from the new treatment systems to the building distribution entry points
and sewer system. In particular, the two connections (i.e., south and north)  to the campus water
distribution network in the College Union were combined for a single inlet tie-in to the Adsorbsia™
GTO™ system in that building.

4.3.3       System Installation, Startup, and Shakedown. The treatment systems arrived at OIT on
October 28, 2005. Quality Water Systems, a local subcontractor to  Kinetico, performed off-loading and
installation of the systems.  The installation activities, which lasted about one week, included placing the
POE systems and 132-gal hydropneumatic tanks in each of the three buildings and connecting system
piping at the tie-in points.

Upon completion of system installation, JOB Consulting, a subcontractor to Kinetico, traveled to the site
on December 5 through 10, 2005, to perform system inspections, hydraulic  testing,  and media loading.
Before media loading, empty vessels were hydraulically tested to check pressure loss at normal flowrates
and observe the flow patterns for uniformity. The media were then  loaded separately through the 6-in
                                              38

flange openings on top of the vessels. No underbedding media support was used for any of the vessels.
Figure 4-15 shows loading of media into one of the vessels in the Residence Hall.  After media loading,
the vessels were backwashed one at a time to remove media fines. For the 30-gpm ArsenXnp system in
the Purvine Hall and the 60-gpm ARM 200 system in the Residence Hall, backwash wastewater ran clear
within a few BV. The Adsorbsia™ GTO™ media in the College Union, however, would not run clear.
                     Figure 4-15. Media Loading into an Adsorption Vessel
Freeboard measurements for the ArsenXnp and ARM 200 systems were taken after media backwash and
the results are summarized in Table 4-9.  Freeboards were measured from the top of the flange to the top
of the media beds.  For the ArsenXnp system, 31.0 to 33.3 in freeboards were measured; these freeboard
measurements resulted in a bed depth of 36.7 to 39.0 in. (Note that bed depths were measured by
subtracting the freeboard from the distance from the bottom of the tank to the top of the flange [i.e., 70
in].) Measurements for the bed depth appeared to be inflated when compared with the design value of 34
in (see Table 4-5).  This was caused by the displacement of media by the lower distributor at the bottom
of each vessel. The ARM 200 system had a bed depth of 48.5 to 50.0 in, compared to the design value of
34 in (see Table 4-6).  The higher actual bed depth values were caused, again, by the displacement of
media by the laterals at the bottom of each vessel. Note that both ArsenXnp and ARM 200 media were
loaded directly into the adsorption vessels without the use of any underbedding support. Because of
issues related to backwashing of Adsorbsia™ GTO™ media, the freeboard measurements and resulting
bed depths obtained during the initial media loading were not considered valid.

After the freeboard measurements, the vendor inspected the systems for leaks, tested individual vessels
and treatment trains for balanced flows, and sanitized the systems with a strong NaOCl solution to a
minimum chlorine residual of 40 mg/L (as C12). By late afternoon on December 10, 2005, the three POE
systems were put online for a test run over the weekend. On the following Monday, "milky" water was
found in the Adsorbsia™ GTO™ system effluent and the system was immediately taken offline.  The

other two POE systems continued to be online and the performance evaluation of these systems officially
began on December 12, 2005.

After discussing the milky white effluent issue with the media manufacturer, Dow Chemical, Kinetico
informed Battelle that Dow Chemical's decision was to rebed the vessels (thinking that the media could
have come from "a bad batch"). Dow Chemical also requested that a garnet underbedding support be
provided in the vessels before rebedding (thinking that the media could have leaked through the bottom
laterals).

According to Kinetico, an underbedding support should have particle sizes between 8 and 50 mesh and a
density over 75 lb/ft3. The underbedding support also should be  installed to a depth about 1 to 2 in above
the bottom laterals. On January 5, 2006, Dow Chemical visited OIT to rebed the vessels at the College
Union.  Prior to rebedding, the previously installed Adsorbsia™  GTO™ media was vacuumed out of the
two vessels and sent to a local landfill for  disposal. The acceptance of the waste was based on Dow
Chemical's TCLP and California Waste Extraction Test (WET) test results using challenge water.  Figure
4-16 shows the Adsorbsia™ GTO™ media after being removed  from the adsorption vessels.

Before media loading, 30 x 40 mesh garnet was installed to provide media support in both vessels.
Following media loading, the lead vessel (Vessel A) was backwashed at 30 gpm for 4 hr and 8.8 gpm for
2 hr for  a total of 55 BV (see Table 4-10). The bed expansion at 30 gpm was roughly 25%.
Approximately 3.5 ft3 of media (or 17% of the total bed volume) was lost even though the bed expansion
was much less than the 66% projected expansion before any media was lost. Non-uniform flow was
suggested by Dow Chemical as a possible cause for the media loss. The lag vessel (Vessel B) was
backwashed the next day at 20 gpm for 1.5 hr before it was terminated due to concerns over high pressure
drop (twice the projected value) across Vessel A in the service mode (Vessel A was in the service mode
when Vessel B was being backwashed). The backwash wastewater appeared turbid from both vessels.
The system remained offline.

Two Battelle staff members traveled to Klamath Falls, OR to conduct system inspections and provide
operator training on data and sample collection on January 10 and 11, 2006.  During the visit, Battelle
collected effluent samples from the newly rebedded Adsorbsia™ GTO™ system at four different service
flowrates, i.e., 5, 30, 45, and 60 gpm. As shown in Figure 4-17, the effluent samples became cloudier as
system flowrates increased incrementally from 30 to 60 gpm. Turbidity measurements also increased
correspondingly from 3 nephelometric turbidity unit (NTU) (at 45 gpm) to 64 NTU (at 60 gpm) (see
Table 4-11). Ap readings across both vessels increased significantly from 5 to 6 psi (at 45 gpm) to 8 to 11
psi (at 60 gpm), indicating that the media was not sufficiently cleaned of fines during the backwash
attempts on January 5 and 6, 2006. Backwashing the lead vessel was attempted using treated water from
the lag vessel at approximately 20 gpm.  However,  after about 1 min into the backwash, the backwash
effluent water turned milky and bulk media were seen entering the bottom of the backwash flowmeter
(Figure 4-18). The backwash attempt was terminated immediately.

On February 17, 2006, Dow Chemical returned to the site to perform media backwash again. The visit
followed a media backwash pilot-scale study conducted at its Midland facilities in Michigan. The lead
vessel (Vessel A) was backwashed at 55 to 60 gpm (or 7.7 to 8.5 gpm/ft2) for 2.5 hr for atotal of 60 BV
(see Table 4-10). To achieve the target backwash flowrate of 60 gpm, the flowrate was slowly increased
over a few minutes. At this flowrate, bed expansions would range between 30 to 35%. The backwash
effluent showed signs of clearing, but maintained a cloudy appearance over the course of the backwash.
Following backwash, the lead vessel was put into the downflow service mode (to drain) at 60 gpm and the
effluent was visibly clear with the turbidity measured at <1 NTU after 10 min.  Due to the various
episodes happening to Vessel A, approximately 4 ft3 of the media was lost from the vessel.

The lag vessel (Vessel B) was then backwashed at 55 to 62 gpm (7.7 to 8.7 gpm/ft2) for 4 hr for a total of
96 BV.  A turbidity of <1 NTU was measured from the effluent after the lag vessel was put into service
                                             42

(to drain) at 60 gpm for 10 min. The amount of media lost from the vessel was 0.5 ft3, or 1 in of the
media bed. The pressure loss across the two vessels was 8 psi at a service flowrate of 60 gpm.

The system was then placed in the lead/lag position (inlet to Vessel A, to Vessel B, and then to the
distribution system) on February 17, 2006, and the performance evaluation study on the Adsorbsia™
GTO™ system officially began on the same day.
4.4
System Operation
4.4.1       Service Operation. Operational parameters of the treatment systems were tabulated and are
attached as Appendix A. Key parameters are summarized in Table 4-12, and discussed in detail below.

4.4.1.1    ArsenX"p System. The performance evaluation study on the ArsenXnp system in Purvine Hall
began on December 12, 2005, and ended on August 26, 2009.  The system operated for a total of 1,353
days, treating 1,814,428 gal (or 24,254 BV) of water (1 BV = 5 ft3/train = 37.4 gal/train or 74.8 gal for
both trains; see arsenic breakthrough behavior in Section 4.5.2.1). Significantly imbalanced flow between
the two parallel trains was observed, with 878,214 gal treated by Train 1 and 936,214 gal treated by Train
2. More detailed discussions about this imbalanced flow are provided in Section 4.4.5.

During the first year of system operation, the average daily demand was 2,077 gal, very close to the
2,073 gal use rate measured during the 24-hr real-time flow measurement on April 4 and  5,  2005.  The
daily demand dropped to 1,542 gal after 2 years of system operation. The average daily demand through
the entire study period was 1,341 gal. The  higher daily demand during the first year of system operation
was due to a higher setting on a trap primer, a solenoid valve that discharged treated water to the drain to
prevent sewer gas from entering the building.

      (a) System went on being rebedded twice with ARM 300 and E33-S media.
      (b) System on-demand; operating time not tracked.
Instantaneous on-demand flowrates to each of the parallel trains ranged from 0.5 to 15 gpm with
combined flowrates ranging from 1 to 27 gpm and averaging 7 gpm. At these flowrates, hydraulic
loading rates ranged from 0.3 to 7.5 gpm/ft2 and averaged 1.9 gpm/ft2, compared to the design value of
8.5 gpm/ft2. Based on the flowrates to the individual trains and system, EBCTs in each vessel varied
from 2.8 to 74.8 min (or 10.7 min on average).

Inlet pressure readings for Trains 1 and 2 ranged from 45 to 67 psi with both averaging 57.0 psi. Outlet
pressure readings for Trains 1 and 2 ranged from 40 to 65 psi with both averaging 57.4 psi. The Ap
across each adsorption vessel remained at 0 psi throughout the performance evaluation study.

4.4.1.2    ARM 200/ARM 300/E33-S System.  The evaluation of ARM 200 media in the Residence
Hall began on December 12, 2005. In 406 days, the system treated 6,698,103 gal (or 44,767 BV) of
water.  (Bed volumes were calculated based on 20 ft3 of media in the lead vessel; see Section 4.5.2.2 for
arsenic breakthrough.) The average daily demand was 16,498 gal, compared to the 14,456 gpd measured
during the 24-hr real-time flow measurement on March 28 and 29, 2005.  Due to the on-demand system
configuration, the flowrates through the ARM 200 system ranged from 1 to 60 gpm and averaged 20.0
                                              44

-------
gpm.  Based on the flow to the system, EBCTs varied from 2.5 to 150 min ( 7.5 gpm [on average]);
hydraulic loading rates varied from 0.1 to 8.5 gpm/ft2 (2.8 gpm/ft2 [on average]).

Inlet pressure readings for the system ranged from 50 to 62 psi and averaged 58.5 psi; outlet pressure
readings ranged from 30 to 62 psi and averaged 54.9 psi. The average Ap across the system was 3.6 psi.
Pressure drops across each ARM 200 vessel were negligible.

The lead vessel (Vessel B) was rebedded with ARM 300 media on January 24, 2007, due to early arsenic
breakthrough from the lead and lag vessels (see Section 4.5.2.2).  Upon rebedding, the vessel containing
ARM 300 was placed in the lag position and the vessel containing partially exhausted ARM 200 media in
the lead position. The ARM 200/ARM 300 test lasted from January 24, 2007, through July 9, 2007, with
the system treating 5,325,660 gal of water (or 35,595 BV). (Bed volumes, again, were calculated based
on 20 ft3 of media in the lead vessel; see discussions of arsenic breakthrough in Section 4.5.2.2)  The
average daily demand was  32,082 gal, which was about twice the amount experienced previously during
the ARM 200 test run. A pipe break at the Residence Hall apparently contributed to the higher water
demand experienced during the ARM 200/ARM 300 test.

As expected, flowrates measured during the ARM 200/ARM 300 test run were higher than the ARM 200
test run, ranging from 14 to 58 gpm and averaging 35.3 gpm.  Correspondingly, EBCTs were shorter
(ranging from 2.6 to 10.7 min and averaging 4.2 min) and hydraulic loading rates were higher (ranging
from 2.0 to 8.2 gpm/ft2 and averaging 5.0 gpm/ft2).  Inlet and outlet pressure readings for the system
averaged 53.6 and 45.4 psi, respectively.  The  resulting pressure drop across the system was 8.2 psi (on
average), which is higher than that observed previously for the ARM 200 system. Pressure losses across
the vessels remained to be negligible, most likely due to errors associated with the pressure gauges.

On July 11, 2007, the system was placed in bypass as the system effluent had exceeded the arsenic MCL
in May 2007. On October 3, 2007, the lead and lag vessels were rebedded with E33-S media. The E33-S
test ran began on October 3, 2007, and ended on August 26, 2009. In 693 days, the system treated
approximately 12,170,210 gal of water (or 81,341 BV).  The average daily demand was 17,562 gal, close
to that observed during the ARM 200 test run.

Operational parameters, including flowrates, EBCTs, hydraulic loading rates, system inlet/outlet pressure
and system differential pressure, measured during the E33-S test run were very close to those measured
during the ARM 200 test run.

4.4.1.3    Adsorbsia™ GTO™ System. Due to the difficulties encountered during the initial media
backwash, the Adsorbsia™ GTO™ system wasn't placed online until February 17, 2006.  During the
1,286 days of system performance evaluation,  the system treated 5,889,749 gal of water. This total
throughput corresponded to 49,212 BV based on 16 ft3 of media in the lead vessel (the lag vessel had 19.5
ft3 of media  [see Table 4-12].) The average daily demand was 4,580 gal. The average daily demand
appeared to increase over time, with 3,776 gal treated, for example, during the first six months of system
operation and 5,162 gal treated during the last year of system operation.

The instantaneous flowrates ranged from 1 to 34 gpm and averaged 6.7 gpm.  Because of the low
flowrates, EBCTs were long (ranging from 3.5 to 120 min  and averaging 17.9 min) and hydraulic loading
rates were low (ranging from 0.1 to 4.8 gpm/ft2 and averaging 0.9 gpm/ft2). Inlet and outlet pressure
readings averaged 60.8 and 59.7 psi, respectively, resulting in only 1.1 psi pressure loss across the
system.  Pressure drops across the vessels were 0 psi throughout the study.

4.4.2       Media Loading and Removal. After the initial media loading, only the ARM 200 system
was rebedded with its lead vessel replaced with ARM 300 media and then placed in the lag position. The
                                              45

-------
ARM 200/ARM 300 system was then rebedded with E33-S media. Rebedding of the lead vessel with
ARM 300 media was performed by Kinetico's local subcontractor, Quality Water System. Before the
removal of spent media, the freeboard was measured as 25.8 in from the top of the flange to the media
surface, which was close to the freeboard (26 in) measured during initial media loading in December 2005.
Spent media samples were collected at the top, middle, and bottom sections of the media bed at depths of 0
to 4, 22 to 26, and 35 to 39 in., respectively.  The vessel was rinsed and any remaining media removed
from the bottom of the vessel. The vessel was then half filled with water before virgin media was poured
through a large funnel from the top of the tank. After the vessel was completely filled with water and the
media was soaked for 1 hr, the vessel was backwashed with 1,440-gal of treated water from Vessel A.
After backwashing, freeboard measurements were taken, and the newly-rebedded Vessel B was placed in
the lag position. The freeboard was 27 in after ARM 300 media loading. On October 3, 2007, the ARM
200/ARM 300 media in the lead and lag vessels were rebedded with E33-S.  The same local subcontractor
rebedded the vessels following the procedure used during the first media changeout.

4.4.3       Backwash Operation. Kinetico recommended that the three POE systems be backwashed
on a regular basis to remove particulates and media fines accumulating in the media beds. Backwash
could be initiated when the pressure differential of any tank was 10 psi greater than that of a clean tank,
after processing 10,000 BV of water,  or after 60 days of operation. Due to negligible pressure drops
across adsorption vessels, the three POE systems were backwashed only once on May 16 or 17, 2006.
Table 4-13 summarizes backwash flowrates and durations and amounts of wastewater produced during
backwash of each of the POE systems.  Backwash flowrates for the two 60-gpm systems ranged 8 to 40
gpm (or 1.1 to 5.7 gpm/ft2), which were significantly lower than the design value of 50 gpm (7.0 gpm/ft2).
The operator used lower backwash flowrates to avoid losing any media during backwash. When
backwashing Adsorbsia™ GTO™ media at 40 gpm, backwash wastewater looked slightly milky. After 4
min into backwash, the operator reduced the flowrate from 40 to 8 gpm.

4.4.4       Residual Management.  Residuals produced by the operation included backwash water and
spent media. There was only one backwash event for each of the three POE systems during the system
performance evaluation.  Approximately 1,540 gal of wastewater was generated, with 580, 480, and 480
gal from the ArsenXnp, ARM 200, and Adsorbsia™ GTO™ systems, respectively.  The backwash
wastewater was discharged to the city sanitary sewer.

On January 24, 2007, approximately 20 ft3 of spent ARM 200 media in the lead vessel at the Residence
Hall was rebedded with ARM 300. The spent media passed TCLP tests (Section 4.5.8), and was disposed
of by Waste Management, Inc. On October 3, 2007, spent ARM 200 and ARM 300 in the lead and lag
vessels were rebedded with E33-S. The spent media was stored at OIT.  In December 2009, the operator
sent an ARM 300 spent media sample to Battelle for TCLP analysis by Belmont Labs.  The spent ARM
300 media passed the TCLP test.

4.4.5       System/Operation Reliability and Simplicity. During the system performance evaluation,
there were no major operational issues except for a few minor leaks, imbalanced flow from the parallel
treatment trains, and a malfunctioned totalizer. Water-dripping leaks were noticed at several union/valve
thread connections of the 30-gpm ArsenXnp system at Purvine Hall right after the system startup and were
repaired on February 28,  2006.

Imbalanced flow was observed between the two treatment trains  of the ArsenXnp system, with each train
treating 878,214 and 936,214 gal of water.  Before the flow restriction valve on each train was adjusted
on February 1, 2006, approximately 40% and 60% of the flow passed through Trains 1 and 2,
respectively. Following the adjustment, the flows through both trains were close with an average of
47.3% and 52.7% passing through Trains 1 and train 2, respectively.

A totalizer malfunction occurred on the  Adsorbsia™ GTO™ system at the College Union on May 18,
2006. The flow totalizer (Kent positive displacement meter) installed on the treated water side of the 60-
gpm system failed to register any flow when the water flowrate was at or below 10 gpm. Clogging of the
meter with particles was thought to be the problem.  The system was restarted in an attempt to flush away
any particles that might have been present; however, the problem persisted until the vendor replaced the
malfunctioned totalizer on July 18, 2006. During the period of totalizer malfunction, the average daily
flow rate calculated based on the meter  reading was 2,108 gal, compared to 4,580 gal prior to the totalizer
malfunctioning. Because the number of consumers and their daily activities remained essentially
unchanged during these two periods, the 54% decrease in average daily usage was likely caused by the
malfunctioning totalizer.  The average daily water usage  of 4,580 gal also was supported by additional
data collected after replacement of the totalizer. As such, the treated water throughput during the period
from May 18 to July 18, 2005, was adjusted based on an average daily water usage of 4,580 gal.

The system O&M and operator skill requirements are discussed below in relation to pre- and post-
treatment requirements, levels of system automation, operator skill requirements, preventive maintenance
activities, and frequency of chemical/media handling and inventory requirements.

4.4.5.1     Pre- and Post-Treatment Requirements. There was no pre- or post-treatment required for
the systems. The pre-existing centralized chlorination system at the wellhead continued to be used for
disinfection purposes.

4.4.5.2     System Automation. The POE systems were designed for complete manual operation.  There
was no electrical connection associated  with the system;  all flow meters and pressure gauges were
mechanical and all valves were manual.  Pressure was the driving force for water flowing through the
treatment systems. During system backwash, manual valves had to be physically opened and closed to
change flow paths and adjust flowrates.
                                              47

-------
4.4.5.3     Operator Skill Requirements.  Under normal operating conditions, the daily demand on the
operator was about 30 min for visual inspection of the system and recording of operational parameters
such as pressure, volume, and flowrate on field log sheets. The O&M of the POE systems required
minimal additional operator skills beyond those required for small system operators, such as a solid work
ethic, basic mathematical skills, ability to understand chemical properties, familiarity with electronic and
mechanical components, and ability to follow written and verbal instructions. Understanding of and
compliance with all occupational and chemical safety rules and regulations  also were required.  Since all
systems were of complete manual operation, the operator was required to understand system piping and
be able to follow the valve chart to operate the system under service and backwash modes after receiving
proper training by the vendor.

All Oregon public water systems, both community and non-transient non-community water systems, must
be under the supervision of a certified operator.  The Oregon DHS Drinking Water Program classifies
water distribution systems and treatment plants into two types according to  their complexity or size and
establishes minimum standards for personnel responsible for operating these systems.  Systems with 149
and fewer connections, either using groundwater as  their only source or purchasing all their water from
another public water system without adding any additional treatment, require an "S" certification; those
with 150  or more connections require certification at "Levels 1 to 4"  for treatment and/or distribution.
The operators of systems with "S" certification are required to attend a small water system training course
once every three years and submit a new Small Water System Operator Application with proof of training
attendance. The OIT Water System is classified as an "S" system and the plant operator attends a training
course once every three years to be qualified as a small water system operator.

4.4.5.4     Preventive Maintenance Activities.  Preventive maintenance tasks recommended by the
vendor included daily to monthly visual inspection of the piping, valves, tanks, flow meters, pressure
gauges, and other system components. Chlorine residual across the treatment train also was checked on a
regular basis using a Hach colorimeter, even though the addition of chlorine was only for disinfection
purposes, and not required by the systems.

4.4.5.5     Chemical Handling and Inventory Requirements. No chemicals were required for the
system operation.

4.5        System Performance

Performance of the three POE systems was evaluated based on analyses of water samples collected across
the treatment trains, from the media backwash, and from the distribution system.  The three POU units
were evaluated by collecting effluent water samples for arsenic analysis. The performance evaluation
studies began on December  12, 2005, for the ArsenXnp system in Purvine Hall and the  ARM 200 system
in the Residence Hall, and on February 17, 2006, for the Adsorbsia™ GTO™ system at the College
Union. The evaluations for all three POE systems were completed on August 26, 2009.

For the ArsenXnp system in Purvine Hall, water samples were collected at six locations: IN, TB1, TA1,
TB2, TA2, and TT (with Vessels TB1 and  TB2 at the lead position).  Sampling was conducted on 36
occasions (including three duplicate sampling events) with field speciation performed at IN and TT for
eight of the 36 occasions.

Sampling in the Residence Hall was conducted on 28 occasions (including three duplicate sampling
events) during the ARM 200 test from January 11, 2006, through January 10, 2007, with field speciation
performed for eight of the 28 occasions.  On January 24, 2007, ARM 200 media in the lead vessel (Vessel
B) was replaced with ARM 300 and the newly-rebedded vessel was placed  in the lag position. Sampling
was conducted on five occasions for the ARM 200/ARM 300 test from February 7, 2007, through June 1,
                                              48

-------
2007, with no field speciation performed during the test.  On July 11, 2007, the system was placed in
bypass until media rebedding. On October 3, 2007, ARM 200 and ARM 300 media in the lead (Vessel
A) and lag vessels (Vessel B) were replaced with E33-S.  Sampling was conducted on eight occasions
from December 18, 2007, through August 26, 2009, with no field speciation performed. Water samples
were collected at IN, TB, and TA for all sampling events.

The late system startup for the Adsorbsia™ GTO™ system at the College Union did not limit the number
of sampling events during the system performance evaluation study. Sampling was conducted on 32
occasions (including three duplicate sampling events) from March 1, 2006, through August 26, 2009,
with field speciation performed on seven of the 32 occasions. Water samples were collected at the
wellhead and following Vessels A and B at IN, TA, and TB for all sampling events.

Tables 4-14 through 4-16 summarize arsenic, iron, manganese, and/or titanium analytical  results for the
ArsenXnp, ARM 200/ARM 300/E33-S, and Adsorbsia™ GTO™ systems, respectively.  Tables 4-17
through 4-19 summarize other water quality parameter results for the three systems. Appendix B contains
a complete set of analytical results collected during the system performance  evaluation. The results of the
water samples collected are discussed below.

4.5.1       Inlet Water to POE Systems.  Inlet water data were extracted from Tables 4-14 to 4-19 and
summarized in Table 4-20. The historic source water data (before chlorination) also were reproduced
from Table 4-3 for comparison. As expected, results of inlet water sampling in each of the three buildings
were similar, as all three buildings received their inlet (chlorinated) water from the same storage tank.

      Outliers excluded from average if all other values are less than the detection limit.
Total arsenic concentrations in inlet water (with samples collected from all three buildings) ranged from
24.7 to 35.8 |o,g/L and averaged 29.7 |o,g/L.  Soluble As(V) was the predominating species, ranging from
26.3 to 35.6 ug/L and averaging 29.8 ug/L.  Soluble As(III) and particulate arsenic concentrations were
low, averaging 0.2 and 0.7 ug/L, respectively. The concentrations of arsenic species in inlet water
sampled during the system performance evaluation were consistent with those of the historical source
water sampling.  Because the inlet water was chlorinated (with 0.3 mg/L of free chlorine [as C12], on
average), it was highly oxidizing, as reflected by high ORP readings (498 mV [on average]) and high DO
levels (3.4 mg/L [on average]).

Similar to the historic results, iron and manganese concentrations in inlet water were low, typically less
than the MDLs at 25 and 0.3 ug/L, respectively.  pH values of the inlet water ranged from 7.3 to 8.5 and
averaged 8.0, which is at the higher end of the commonly recommended range of 5.5 to 8.5 for arsenic
removal by adsorptive media.  Media run lengths at pH 8.0 most likely would be shorter than the runs at
                                               51

for
lower pH values.  Lowering pH values prior to adsorption can prolong the adsorption runs, but often is
avoided by small system operators because of the need to handle acids and bases. When benefits of
lowering pH values are out-weighed by concerns over the handling of acids and bases, pH adjustments
are not performed.

Competing anions such as silica and phosphorus were measured in source water during the initial site
visit and in inlet water during the performance evaluation study. Analysis of inlet water showed silica
levels at 27.8 to 31.5 mg/L (as SiO2), compared to 30.3 to 34.2 mg/L (as SiO2) in source water during the
initial site visit. Silica adsorption by the five adsorptive media tested is discussed in detail in
Section 4.5.2.  Total phosphorus in inlet water was below its MDL of 10 (ig/L, consistent with the
measurements of orthophosphate levels measured (below the MDL of 0.06 mg/L  [as PO4]) during the
initial site visit.

Other analytes measured were either low or close to or below their respective MDLs. Their effects on
arsenic removal by the media evaluated were expected to be minimal.

Treated Water Following Media Adsorption
4.5.2.1     ArsenX"p. Figure 4-19 presents arsenic breakthrough curves at TB1, TA1, TB2, TA2, and
TT. Arsenic breakthrough at 10 (ig/L following the lead vessels (TB1 and TB2) occurred after treating
approximately 594,440 and 609,700 gal of water (or 15,900 and 16,300 BV), respectively.  (BV was
calculated based on 5 ft3 of media in a lead vessel.)  These run lengths represented only approximately
30% of the 52,750-BV run length estimated by the vendor.  By the end of the performance evaluation
study, arsenic levels following the two lead vessels were approaching those in inlet water. At this time,
the system had treated 1,814,428 gal (or 24,254 BV [1 BV = 10 ft3 of media in both lead vessels]) of
water.  The run-length differences observed between the two trains were caused by the imbalanced flow
experienced during the initial stage of system operation (see Section 4.4.5).

At the end of the performance evaluation study, arsenic concentrations following the lag vessels (TA1 and
TA2) were 0.4 ug/L.  Since then, the system continued to treat and provide drinking water to taps in
Purvine Hall.

Figure  4-20 presents silica breakthrough curves from the treatment system. Silica broke through from the
treatment system soon after system startup. Complete silica breakthrough  occurred at approximately
5,000 BV (1 BV = 10 ft3 of media in both lead vessels).  Silica adsorption has been observed at a number
of arsenic demonstration sites using AM; a review of silica adsorption at these sites was documented in a
system performance evaluation  report authored by Chen et al. (2010).

4.5.2.2     ARM200/ARM300/E33-SMedia.  Figure 4-21 presents breakthrough curves following the
lead and lag vessels. Total arsenic concentrations exceeded 10 (ig/L after the lead vessel (TB) containing
ARM 200 had treated 2,085,000 gal (or 13,940 BV) of water. (BV was calculated based on 20 ft3 of
media in the lead vessel.)  The BV was only 22% of the vendor-estimated run length of 62,600 BV.
Since then, total arsenic concentrations following the lead vessel fluctuated between 9.9 and 12.6 (ig/L
before spiking to 17.6, 28.5, and 30.3 (ig/L at 27,800, 36,200, and 39,400 BV, respectively.  By the end of
the ARM 200 test, total arsenic concentrations following the lead vessel had reached the inlet water level
of approximately 30 (ig/L. At this time, the lead vessel had treated approximately 6,698,000 gal of water
(or 44,770 BV [1 BV = 20 ft3 = 149.6 gal]).

         Figure 4-21.  Total Arsenic Breakthrough from ARM 200 and/or ARM 300 Media
Breakthrough of total arsenic at 10 (ig/L following the lag vessel (TA) containing ARM 200 media
occurred at 34,078 BV (1 BV = 20 ft3 of media in one vessel). Considering the lead and lag vessels as
one large vessel, breakthrough at 10 (ig/L in system effluent would occur at 17,039 BV (1 BV = 40 ft3 of
media in both vessels). The difference between the two-vessel and one-vessel run lengths (17,039 vs.
13,940 BV) likely was caused by twice as long EBCT for the lead/lag system. By the end of the ARM
200 test, the total  arsenic concentration in the system effluent had reached 19.5 (ig/L.

Because of the unexpected early arsenic breakthrough, the system was taken offline and the lead vessel
was rebedded with ARM 300 when the lag vessel had an arsenic effluent concentration of 19.5 (ig/L.
After vessel switching (with partially spent ARM 200 in the lead position and virgin ARM 300 in the  lag
position), the system was put online on January 24, 2007. The lead vessel containing partially spent
ARM 200 (TA) continued to remove arsenic but the percentage removal was diminishing from about 21%
                                                59

-------
at 3,200 BV (since rebedding and vessel switching) to <9% at 31,300 BV (1 BV = 20 ft3 = 149.6 gal).
Total arsenic concentrations from the lag vessel (TB) reached 9.5 (ig/L on April 4, 2007 after treating
2,327,650 gal (or 15,557 BV) of water. This run length was very close to that (13,940 BV) for ARM 200.

Because of the short run lengths experienced with both ARM 200 and ARM 300 media, the system was
put in the standby mode on July 11, 2007, pending results of a series of rapid small-scale column tests
(RSSCTs) funded under another EPA task order. The RSSCTs evaluated the run lengths of five different
adsorptive media (i.e., ArsenXnp, ARM 200, GFH [a granular ferric hydroxide media developed by GEH
Wasserchemie Gmbh and marketed by Siemens], Metsorb [a titanium dioxide-based media developed by
HydroGlobe], and E33-S) using 100 x 140 U.S. standard mesh media fractions packed separately in 1.1-
cm x 30.5-cm glass columns. The results indicated that E33-S was able to achieve a useful run length of
approximately 40,000 BV, while the rest would achieve only 12,000 to 20,000 BV. As such, E33-S was
used to rebed both lead and lag vessels on October 3, 2007, and the system was put back online
immediately for additional testing.

E33-S media treated approximately 7,480,000 gal (or 50,000 BV [1 BV = 20 ft3 = 149.6 gal]) of water
before effluent concentrations from the lead vessel exceeded the 10-(ig/L MCL (see Figure 4-22). This
run length was 20% longer than the RSSCT-projected run length and much longer than those achieved by
ARM 200 (13,940 BV), ARM 300 (16,200 BV [with 8.6 to 20.1% of arsenic already removed by ARM
200 media]), and ArsenXnp (16,000 BV). During the last sampling event on August 26, 2009, the arsenic
concentration following the lag vessel was 3.1 (ig/L. By now, the system had treated 12,170,210 gal of
water (equivalent to 40,670 BV based on 40 ft3 of media in both vessels).

Removal of silica (as SiO2) by ARM 200 was observed during the initial stage of the ARM 200
adsorption run. Because only two samples were collected during the first three months of system
operation and because silica concentrations had already reached inlet levels during the second sampling
event (at approximately 9,400 BV), precise silica breakthrough behavior may not be determined using the
available data (see Figure 4-23).

4.5.2.3     Adsorbsia™ GTO™. Figure 4-24 shows total arsenic breakthrough from Adsorbsia™
GTO™ media.  Total arsenic concentrations following the lead vessel (TA) remained below 1.1 (ig/L
after the system had treated 2,571,229 gal of water (or 21,484 BV based on 16 ft3 of media in the lead
vessel). Since then, total arsenic concentrations rose sharply to 10 (ig/L after treating an additional
12,000 BV of water. Afterwards, total arsenic concentrations continued to increase to 24.3  ug/L in 7,200
BV. During the last sampling event of the system performance evaluation study, the arsenic
concentration following the lead vessel was 21.1 ug/L, which was within 22% to the inlet level; the
arsenic concentration following the lag vessel (TB) was 0.6 ug/L. At this time, the system had treated
5,889,749 gal of water (equivalent to 21,872 BV based on 36 ft3 of media). The vendor-estimated media
life was 60,150 BV, which was about 80% higher than the run length achieved by the lead vessel.

Silica did not seem to compete with arsenic for adsorption sites, as evidenced by the same level of silica
in the treated water.

4.5.2.5     POU Units. Figures 4-25 and 4-26 show total arsenic concentrations following three POU
units loaded with ARM 200 media and three POU units loaded with E33-S, respectively.  Total arsenic
was consistently removed to less than 1.0 (ig/L from ARM 200 Units 1 and 2 after treating approximately
400 and 740 gal of water, respectively. ARM 200 Unit 3 effectively removed arsenic to <2.1 (ig/L after
treating 500 gal, but the effluent arsenic concentrations rose steadily to 6.0 after treating approximately
1,000 gal. Arsenic was consistently removed to the MDL level by the three E33-S POU units after
treating approximately 500 gal.  A follow-on study that allowed inlet water to flow through an E33-S
POU unit at about 1 gpm showed the concentration reduction to <10 ug/L by the unit during the first
3,000 gal of throughput (Figure 4-27).

4.5.6       Backwash Wastewater Sampling.  Table 4-22 summarizes analytical results of the
backwash wastewater sampling during backwash of the three POE systems on May 16 or 17, 2006. The
unfiltered samples were analyzed for pH, TDS, TSS,  and total arsenic, iron, and manganese.  Filtered
samples using 0.45-|o,m disc filters were analyzed for soluble arsenic, iron, and manganese. Backwash
solid results are presented in Table 4-23.

4.5.6.1     ArsenX"p System. The lead vessels (TB1 and TB2) were backwashed using treated water
from the lag vessels (TA1 and TA2) in the same  train.  Similarly, the lag vessels (TA1 and TA2) were
backwashed using treated water from the lead vessels (TB1 and TB2) in the same train. The  treated water
from the lag and lead vessels contained, at the time, no more than 0.1 |o,g/L of total arsenic. Wastewater
collected from the two lead vessels contained 15.2 and 14.3 (ig/L of total arsenic, respectively, existing
primarily in the soluble form (this is contrary to what would be expected). Wastewater collected from the
two lag vessels contained only 0.2 (ig/L of total arsenic, similar to the level in the treated water. Solids in

the backwash wastewater, as reflected by TSS at 4 to 60 mg/L, most likely were media fines measured as
particulate iron (at 389 to 2,758 (ig/L).  The unusually low TSS value (4 mg/L) measured at TB2 might
have been the result of sampling errors caused by insufficient mixing of the solids/water mixtures in the
backwash water collection containers immediately before sampling.  Based on an average TSS level of 42
mg/L (excluding the 4 mg/L outlier) and the quantity of backwash wastewater produced (144 gal/vessel),
approximately 91.6 g of solids was discharged during the backwash event. The discharged solids
contained negligible amount of arsenic (due to the low particulate arsenic concentrations in the
wastewater) and 5.2 g of iron (5.6% by weight), which does not reconcile well with the  91.6-g TSS
measured in the wastewater sample or the 18.7% iron measured in the backwash solids (see Table 4-25).
The solids analysis showed low arsenic and manganese loadings at 0.04% and 0.11%, respectively.

4.5.6.2     ARM200 System. Backwash was performed using treated water from the other vessel in the
treatment system.  At the time of backwash, the treated water from the lead and lag vessels contained no
more than 11.1 and 0.3 (ig/L of arsenic, respectively. However, the backwash water from the lead and lag
vessels contained 19.0 and 13.9 (ig/L of arsenic, respectively. Again, the majority of arsenic in the
wastewater existed as soluble arsenic. As expected, more arsenic was found from the lead than the lag
vessel, due the higher arsenic loading in the lead vessel (even though the treated water from the lag vessel
used for backwashing the lead vessel contained less arsenic). The TSS levels were 6 and 34 mg/L for the
lead and lag vessels, respectively. The low TSS value found for the lead vessel might be the result of
sampling errors as discussed above. Based on the TSS levels (6 and 34 mg/L) and the quantity of
backwash water produced (350 and 136 gal), approximately 25.4  g of solids was discharged during the
backwash event.  The discharged solids contained 3.6 g of iron (or 14.1% by weight) but negligible
amounts of arsenic and manganese.  Similar to the ArsenXnp solid results, the individual elemental results
do not reconcile well with the TSS results or backwash solids results (i.e., 41% iron, 0.3% manganese,
and 0.04% arsenic).

4.5.6.3     Adsorbsia™ GTO™ System. Similar to the ARM 200 system in the Residence Hall,
backwash of the Adsorbsia™ GTO™ system was performed using treated water from the  other vessel in
                                              65

the treatment system. At the time of backwash, the treated water from the lead and lag vessels contained
no more than 0.6 and 0.1 (ig/L of arsenic, respectively.  Backwash water analytical data indicated more
arsenic from the lead vessel (i.e., 10.9 vs. 1.3 ug/L) due to more arsenic loading.  The majority of the total
arsenic in the backwash water was in the soluble form.  Based on the TSS levels (120 and 62 mg/L) and
the quantity of backwash water produced (240 gal/vessel), approximately 165g of solids was discharged
during the backwash event. Because titanium was not analyzed, its amount in backwash wastewater
could not be estimated.  However, based on the amounts measured in backwash solids, over 34% of the
solids could be present as titanium.

4.5.7       Distribution System Water Sampling.  Prior to the installation/operation of the three POE
treatment system, first draw baseline distribution system water samples were collected at three locations
on July 13, August 4, August 24, and September 14, 2005. Following the installation of the treatment
system, distribution water sampling  continued on a monthly basis until April 4, 2007. Table 4-24
summaries results of the distribution system sampling.

The most noticeable change in the distribution water samples after system startup was decreases in
arsenic concentration at all three locations.  Baseline arsenic concentrations for all three locations ranged
from 25.6 to 36.0 (ig/L and averaged 29.2 (ig/L. After system startup, arsenic concentrations ranged from
<0.1 to 1.7 (ig/L and averaged 0.8 (ig/L (excluding one outlier at 7.3 (ig/L on April 4, 2007) in Purvine
Hall and ranged from <0.1 to 1.4 (ig/L and averaged 0.6 (ig/L (excluding one outlier at 3.6 (ig/L on March
8, 2007) in the College Union.  Distribution system water samples in the Residence Hall essentially
mirrored ARM 200 system effluent (although arsenic concentrations in the distribution system water
samples taken during the first several months of system operation were, in general, higher than those in
the system  efflent, suggesting resuspension, solublization, and/or desorption of arsenic-laden
particles/scales in the distribution system). Arsenic concentrations exceeded the 10 (ig/L MCL on
December  13, 2006 and January 10, 2007, before the lead vessel was rebedded with ARM 300 on January
24, 2007.

Post-baseline lead concentrations ranged from <0.1 to  1.6 (ig/L, with none of the samples exceeding the
action level of 15 (ig/L. Post-baseline copper concentrations ranged from 39.7 to 448 (ig/L across all
sampling locations, with no sample exceeding the 1,300 (ig/L action level.  The arsenic treatment systems
do not seem to affect lead or copper concentrations in the distribution system.

Measured pH values ranged from 7.5 to 8.1 and averaged 7.9 at all three locations. Alkalinity levels
ranged from 104 to 137 mg/L (as CaCO3). The arsenic treatment systems do not seem to affect these
water quality parameters in the distribution system.

4.5.8       Spent Media Sampling.  Three ARM 200 spent media samples were collected from the top,
middle, and bottom of the lead vessel in the Residence Hall during the media changeout on January 24,
2007. Tables 4-25 and 4-26 present metals and TCLP  results, respectively.  Arsenic, barium, and
chromium were detected at concentrations slightly higher than their respective detection limit. The other
TCLP metals were less than the respective MDLs. Because the media passed the TCLP test, it can be
disposed of as non-hazardous waste.

The ICP-MS results of the spent media indicated that the media contained mostly iron at 569 mg (as Fe)/g
of dry media or 56.9% by weight. The chemical formula that best represents the iron media was not
available from the product literature. The spent media also contained trace levels of Al, Ca, Cu, Mg, Mn,
P, and Si at 0.58, 11.8, 0.65, 1.0, 1.7, 0.54, and 0.42 mg/g, respectively. Some of these elements were
detected in inlet water and apparently were removed by ARM 200 media. The spent media also removed
some Al, Cu, Pb, and Zn from inlet water, as evidenced by the decreasing loadings from the top to the
bottom of the media bed.  It is not clear what mechanisms were involved in the  removal of these cations.

The arsenic loading on the spent media based on the ICP-MS results was 0.83 mg/g (average across bed
from Table 4-25). For comparison to the spent media results, the adsorptive capacity was calculated by
dividing the arsenic mass removed by the amount of dry media in the lead vessel. The arsenic mass
removed was estimated by multiplying the average throughput to the 10-(ig/L breakthrough (15,490 BV,
see Table 4-21) by the average arsenic level in inlet water (29.7 ug/L). The dry weight of the media, i.e.,
874 Ib, was calculated based on a wet weight of 950 Ib (i.e., 20 ft3 of media at 47.5 lb/ft3)  and a moisture
content of 8% (Table 4-3). Using this approach, the arsenic loading for the spent media was 0.66 mg/g of
dry media.  The ICP-MS analysis appeared to over-recover by 26%.

4.6        System  Cost

The system cost was evaluated based on the capital cost per gpm (or gpd) of the design capacity and the
O&M cost  per 1,000 gal of water treated. Capital cost for the treatment system included the expenditure
for equipment, site engineering, and system installation, shakedown, and startup.  O&M cost included the

expenditure for media replacement and labor. The cost associated with the plumbing modification was
not included in the capital cost because it was out of the scope of the demonstration project, and was
funded separately by OIT.

4.6.1       Capital Cost. The total capital investment for the Kinetico POE systems and POU units was
$198,958, which included $142,448 (71.6%) for equipment, $33,560 (16.9%) for site engineering, and
$22,950 (11.5%) for installation. Table 4-27 presents cost breakdowns provided by the vendor. The
equipment cost was broken down for major cost components such as adsorptive media, filter vessels,
hydropneumatic tank, process valves and piping, labor, and shipping for each system.

The site engineering cost included the cost for preparing a process design report and required engineering
plans, including a general arrangement drawing, piping and instrumentation diagram (P&ID), inter-
connecting piping layouts, tank fill details, and other associated drawings. After being certified and
stamped by an Oregon-registered professional engineer, the plans were submitted to Oregon DHS for
permit review and approval.

To calculate the normalized capital cost based on the design capacity of each POE system, the composite
engineering cost and installation cost provided by the vendor were broken down proportionally for each
system based on the ratio calculated from their equipment cost breakdown. The rearranged cost
breakdowns for each POE system are summarized in Table 4-28.

       (a) Including shipping and labor cost.
4.6.1.1     ArsenX"p System. The capital cost of $55,847 was normalized to $l,862/gpm ($1.29/gpd) of
design capacity using the system's rated capacity of 30 gpm (or 43,200 gpd).  The capital cost also was
converted to an annualized cost of $5,271/yr using a capital recovery factor (CRF) of 0.09439 based on a
7% interest rate and a 20-yr return period.  Assuming that the system operated 24 hr/day, 7 day/wk, and
365 day/yr at the design flowrate of 30 gpm, the unit capital cost would be $0.33/1,000 gal. During the
system performance evaluation, the system treated an average of 489,480 gal/yr (see Table 4-12); at this
reduced rate of usage, the unit capital cost increased to $10.77/1,000 gal.

4.6.1.2     ARM200 System.  The capital cost of $59,516 was normalized to $992/gpm ($0.69/gpd) of
design capacity using the system's rated capacity of 60 gpm (or 86,400 gpd).  The capital cost also was
converted to an annualized cost of $5,618/yr using a CRF of 0.09439 based on a 7% interest rate and a
20-yr return period. Assuming that the system operated 24 hr/day, 7 day/wk, and 365 day/yr at the design
flowrate of 60 gpm, the unit capital cost would be $0.18/1,000 gal.  The system was operated on demand,
producing 6,698,103 gal of water in 406 days during the ARM 200 test (see Table 4-12). At this reduced
rate of operation  (i.e., 6,021,694 gal/yr), the unit capital cost increased to $0.93/1,000 gal.

4.6.1.3     Adsorbsia™ GTO™ System.  The capital cost of $73,258 was normalized to $l,221/gpm
($0.85/gpd) of design capacity using the system's rated capacity of 60 gpm (or 86,400 gpd).  The capital
cost also was converted to an annualized cost of $6,915/yr using a CRF of 0.09439 based on a 7% interest
rate and a 20-yr return period. Assuming that the system operated 24 hr/day, 7 day/wk, and 365 day/yr at
the design flowrate of 60 gpm, the unit capital cost would be $0.22/1,000 gal. During the evaluation
study, the system produced 5,889,749 gal of water in 1,286 days (or 1,671,663 gal/yr; see Table 4-12); at
this reduced rate  of usage, the unit capital cost increased to $4.14/1,000 gal.

4.6.2       Operation and Maintenance  Cost. The O&M cost included the cost for replacing media
and the cost of labor to operate the systems, as summarized in Table 4-29 for the three POE systems.
Media replacement is a major cost for operating an adsorptive media system.  According to vendor
estimates, it would cost $11,900 to replace  20 ft3 of ArsenXnp, $18,700 to replace 40 ft3 of ARM 200,
$12,000 to replace 40 ft3 of E33-S, and $27,100 to replace 40 ft3 of Adsorbsia™ GTO™.  Therefore, the
unit cost from the lowest to the highest would be $300/ft3 for E33-S, $468/ft3 for ARM 200, $595/ft3 for
ArsenXnp, and $678/ft3for Adsorbsia™ GTO™. These estimates do not include the cost for labor, travel,
freight, spent media analysis, and media disposal. These costs are expected to be similar regardless of the
media type.

      (a) Cost for labor, travel, freight, spent media analysis, and media disposal fee not included in quote,
         but expected to be similar regardless of media type.
      (b) Media quote provided by Kinetio in August 2005 except for E33-S, which was provided by a local
         vendor.
Based on the actual cost incurred to replace 20 ft3 of ARM 200 at the Residence Hall in February 2007,
the media cost was $7,700 and the labor and travel cost for emptying one vessel, disposing spent media,
and reloading the new media was $3,500. The labor cost could be less if a local vendor was hired for the
job with the assistance of the operator.  To help select the most cost-effective media, a cost curve was
constructed for each media type in terms of media cost per 1,000 gal of water treated as a function of the
projected media run length to the 10-|o,g/L arsenic breakthrough (Figure 4-28).  For example, the average
ARM 200 media run length at the Residence Hall was 13,490 BV (Table 4-21), so the media cost based
on Figure  4-28 was approximately $4/1,000 gal. The actual media replacement cost incurred was
$11,200, which translated to $5.55/1,000 gal.

Under normal conditions, routine labor activities to operate and maintain each POE system consumed 30
min per day on average, or 2.5 hr for a five-day week. Based on this time  commitment and a labor rate of
$21/hr, the annual labor cost was estimated to be $2,730 to operate each POE system.  Depending on the
annual water production of each POE system, the normalized labor cost was $5.58/1,000 gal for the
Purvine Hall system and $1.63/1,000 gal for the College Union system. At Residence Hall, the estimated
labor cost was similar for the ARM  200 and E33-S media runs, which was $0.45/1,000 gal and
$0.43/1,000 gal, respectively.
