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 activities performed for and results obtained from the arsenic removal treatment
technology demonstration project at the Hot Springs Mobile Home Park (HSMHP) in Willard, UT. The
objectives of the project were to evaluate the effectiveness of Adsorbsia  GTO   adsorptive media
combined with Birm®/Filox  oxidizing media (as a pretreatment) in removing arsenic to meet the new
arsenic maximum contaminant level (MCL) of 10 |o,g/L. Additionally, this project evaluated (1) the
reliability of the treatment system, (2) the required system operation and maintenance (O&M) and
operator skill levels, and (3) the capital and O&M cost of the technology.  The project also characterized
the water in the distribution system and process residuals produced by the treatment process.

The water system at HSMHP was supplied by a supply well (Well No. 2) and  a backup well (Well No. 1).
Arsenic concentrations in source water from Well No. 2 ranged from 9.4 to 21.1 |o,g/L and averaged 13.2
(ig/L. Of the soluble fraction, As(III) and As(V) each accounted for almost half of the concentrations.
Source water also contained, on average, 276 (ig/L of total iron and 116 (ig/L  of total manganese.
Therefore, pretreatment was needed to remove iron and manganese and oxidize soluble As(III) to soluble
As(V) prior to adsorption by Adsorbsia  GTO  .
The 30-gal/min (gpm) arsenic treatment system consisted of two integral parts. The oxidation/filtration
unit consisted of two 24-in x  72-in vessels, each containing 5 ft3 of Birm® and 5 ft3 of Filox  media; the
adsorption unit consisted of one 24-in x 72-in vessel containing 10 ft3 of Adsorbsia  GTO   media (the
actual amount was 10.3 ft3). Birm® is a manganese dioxide-coated media and Filox  is a manganese
dioxide-based media; both are commonly used for iron and manganese removal. Adsorbsia  GTO  is a
granular titanium oxide media manufactured by the Dow Chemical Company for arsenic removal.

Operation of the treatment system began on December 11, 2008. The types of data collected included
system operation, water quality (both across the treatment train and in the distribution system), process
residuals, and capital and O&M cost. During the performance evaluation study period  from December
11, 2008, through October 18, 2010, the system treated 5,629,000 gal (or 73,010 bed volumes [BV]) of
water based on a flow meter/totalizer installed on the adsorption vessel and 10.3 ft3 (or 77.1 gal) of
Adsorbsia  GTO   media in the vessel.  Daily run times averaged 23.4 hr/day and daily water demands
averaged 8,354 gpd. Flowrates to the adsorption vessel varied extensively from 0.7 to 24.0 gpm and
averaged 7.3 gpm. Due to the fluctuating flowrates, empty bed contact times (EBCTs)  in the adsorption
vessel varied extensively from 3.2 to  110 min and averaged 10.6 min. The average EBCT was four times
the vendor recommended value of 2.5 min.

Pretreatment with Birm®/Filox™ removed approximately 21% of total arsenic, leaving 10.4 (ig/L (on
average) in the influent to the adsorption vessel. Total arsenic at this point existed mainly as soluble
As(V), indicating effective oxidation of soluble As(III) by Birm®/Filox™. Birm®/Filox™ also was
effective in removing iron and manganese, reducing their concentrations to <25 and 4 (ig/L (on average),
respectively. Daily backwashing appeared to be effective in maintaining Birm®/Filox™ performance; no
sign of iron leakage or media fouling was observed during the performance evaluation study.

Adsorbsia™ GTO™ further removed soluble As(V) to below the 10-(ig/L arsenic MCL throughout the 22-
month study period.  By the end of the performance evaluation study, the total arsenic concentration in
the system effluent was 6.2 (ig/L.  At this point, the system had treated approximately 69,200 BV of
water, compared to the vendor estimated media life of 168,000 BV.
                                              IV

-------
Each pre-oxidation vessel was backwashed daily at 47 gpm for 8 min, producing 376 gal of wastewater
(752 gal for two vessels).  The wastewater contained 29.8 mg/L (on average) of total suspended solids
(TSS); therefore, 85 g (0.2 Ib) of solids were discharged daily.  As expected, the solids were comprised
mainly iron (8.9 g).

Comparison of the distribution system sampling results before and after system startup showed significant
reductions in total arsenic, iron, and manganese concentrations. Total arsenic concentrations decreased
from an average of 11.2 to 3.2 (ig/L; total iron from 70 (ig/L to less than the method detection limit
(MDL) of 25 ug/L; total manganese from 19.5 to 8.8 (ig/L.  Neither lead nor copper concentrations at the
consumers' taps appeared to have been impacted by system operation.

The capital investment cost for the system was $66,362, including $46,267 for equipment, $3,850 for site
engineering, and $16,245  for installation. Using the system's rated capacity of 30 gpm (43,200 gal/day
[gpd]), the normalized capital cost was $2,212/gpm ($1.54/gpd). The O&M cost included the cost for
media replacement and disposal, electricity consumption, and labor.  Neither the oxidizing nor the
adsorptive media required replacement during the study period. The media replacement and disposal cost
would represent the majority of the O&M cost and was estimated to be $8,175 for 20 ft3 of Birm®/Filox™
and $8,440 for 10 ft3 of Adsorbsia™ GTO™. It was estimated that both Birm®/Filox™ media would have a
life expectancy of 10 years.

                                    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
established 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). In order 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 to reduce compliance costs. 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, on-site demonstrations of arsenic removal
technologies, process modifications, and engineering approaches applicable to small systems.  Shortly
thereafter, an announcement was published in the Federal Register requesting 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 out of 115 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 from one to six proposals.  In April 2003, an independent technical panel
reviewed the proposals and provided its recommendations to EPA on the technologies that it determined
were 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.  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 from two to eight proposals. In April 2004, another technical panel was convened by EPA to
review the proposals and provide recommendations to EPA with the number of proposals per site ranging
from none (for two sites) to a maximum of four. The final selection of the treatment technology at the
sites that received at least one proposal was made, again, 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.

With additional funding from Congress, EPA selected 10 more sites for demonstration under Round 2a.
Among the sites selected was the Hot Springs Mobile Home Park (HSMHP) in Willard, Utah. Somewhat
different from the Round 1 and Round 2 process, Battelle, under EPA's guidance, issued a Request for
Proposal (RFP) on February 14, 2007, to solicit technology proposals from vendors and engineering
firms.  Upon closing of the RFP on April 13, 2007, Battelle received from 14 vendors a total of 44
proposals, which were reviewed by a three-expert technical review panel convened at EPA on May 2 and

-------
3, 2007.  Copies of the proposals and recommendations of the review panel were later provided to and
discussed with representatives of the  10 host sites and state regulators in a technology selection meeting
held at each host site during April through August 2007. Final selections of the treatment technology
were made, again, through a joint effort by EPA, the respective state regulators, and the host sites.
Adsorbsia™ GTO™ adsorptive media combined with a Birm®/Filox™ oxidizing media pretreatment was
selected for demonstration at  HSMHP in Willard, UT. The treatment system was provided by Filter Tech
Systems, Inc. (Filter Tech) in Grand Junction, CO.

As of July 2011, all 50 systems were  operational and the performance evaluations of 49 systems were
completed.

1.2         Treatment Technologies for Arsenic Removal

Technologies selected for Rounds 1, 2, and 2a demonstration included adsorptive media (AM), iron
removal (IR), coagulation/filtration (C/F), ion exchange (IX), reverse osmosis (RO), point-of-use (POU)
RO, and system/process modification. Table 1-1 summarizes the locations, technologies, vendors, system
flowrates, and key source water quality parameters (including As, iron [Fe], and pH).  Table 1-2 presents
the  number of sites for each technology.  AM technology was demonstrated at 30 sites, including four
with IR pretreatment. IR technology was demonstrated at 12 sites, including four with supplemental iron
addition. C/F, IX, and RO technologies were demonstrated at three, two, and one sites, respectively. The
Sunset Ranch Development site that demonstrated POU RO technology had nine under-the-sink RO
units.  The Oregon Institute of Technology (OIT) site classified under AM had three AM systems and
eight POU AM units. The Lidgerwood site encompassed only system/process modifications. 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/arsenic/resource.htm.

1.3         Project Objectives

The objective of the arsenic demonstration program was to conduct full-scale performance evaluations of
treatment technologies for arsenic removal from drinking water supplies. The specific objectives were 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 cost of the technologies.

This report summarizes the performance of the arsenic removal system at the HSMHP in Willard,  UT
from December 11, 2008, through October 18, 2010. The types  of data collected included 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 during the 22 months of system operation, the following summary and
conclusions were made relating to the overall objectives of the treatment technology demonstration study.

Performance of the arsenic removal technology for use on small systems:
       •   The use of Birm® in combination with Filox™is effective in removing iron and manganese
           and oxidizing soluble As(III). No chemical addition or regeneration is required for Birm® or
            ..   TM
           Filox .

       •   A daily backwash for 8 min appears to be adequate to maintain Birm®/Filox™ media
           performance and prevent media fouling. Adsorbsia™ GTO™ media does not require
           backwash.

       •   Adsorbsia™ GTO™ media can effectively remove soluble As(V) to below  10 (ig/L.  By the
           last sampling event, total arsenic concentrations following Adsorbsia™ GTO™ reached 6.2
           (ig/L after treating approximately 69,200 bed volumes (BV) of water.
Required system O&Mand operator skill levels:
       •   The system is simple to operate. The daily demand on the operator was typically 30 min to
           visually inspect the system and record operational parameters.

Process residuals produced by the technology:
       •   The only residual produced from system operation was Birm®/Filox™ backwash wastewater.
           The amount of wastewater produced amounted to about 10% of the water  production, caused
           by a high backwashing frequency (i.e., daily).

       •   Based on an average of 29.8  mg/L of total suspended solids (TSS) in 752 gal of wastewater
           produced by backwashing the two vessels daily, approximately 85 g of solids would be
           discharged daily. The solids contained 102 mg of arsenic, 8.9 g of iron, and 1.6 g of
           manganese.

Capital and O&M cost of the technology:
       •   The unit capital cost was $0.40/1,000 gal of water treated if the system operated at a 100%
           utilization rate. The system's actual unit cost was $2.05/1,000 gal, based on a daily average
           water production of 8,354 gal (i.e., about 19% utilization).

       •   The O&M cost per 1,000 gal of water treated would be $2.20 plus the Adsorbsia™ GTO™
           media replacement cost per actual run length.

3.1
General Project Approach
Following the predemonstration activities summarized in Table 3-1, the performance evaluation study of
the dual oxidizing media and Adsorbsia   GTO  arsenic removal system began on December 11, 2008,
and ended on October 18, 2010.  Table 3-2 summarizes the types of data collected and considered as part
of the technology evaluation process. The overall system performance was evaluated based on its ability
to consistently remove arsenic to below the MCL of 10 (ig/L through the collection of water samples
across the treatment train, as described in the Study Plan (Bartelle, 2008). The reliability of the system
was evaluated by tracking the unscheduled system  downtime and frequency and extent of repair and
replacement. The plant operator recorded unscheduled downtime and repair information on a Repair and
Maintenance Log Sheet.

The O&M and operator skill requirements were evaluated based on a combination of 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. The 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 and solids were sampled and
analyzed for chemical characteristics.
The cost of the system was evaluated based on the capital cost per gal/min (gpm) (or gal/day [gpd]) of
design capacity and the O&M cost per 1,000 gal of water treated. This task required tracking the capital

3.2
System O&M and Cost Data Collection
The plant operator performed daily, biweekly, and monthly system O&M and data collection according to
instructions provided by the vendor and Battelle.  On a regular basis, the plant operator recorded system
operational data such as pressure, flowrate, totalizer, and hour meter readings on a System Operation Log
Sheet and conducted visual inspections to ensure normal system operations.  When problems occurred,
the plant operator contacted the Battelle Study Lead, who determined if the vendor should be contacted
for troubleshooting.  The plant operator recorded all 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 also measured
temperature, pH, dissolved oxygen (DO), and oxidation-reduction potential (ORP) and recorded the data
on an Onsite Water Quality Parameters Log Sheet.

The capital cost for the arsenic removal system consisted of the cost for equipment, site engineering, and
system installation. The O&M cost consisted of the cost for electricity consumption, and labor. Labor
for various activities, such as the routine system O&M, troubleshooting and repairs, and demonstration-
related work, was tracked using an Operator Labor Hour Log Sheet.  The routine system O&M included
activities such as completing field logs, 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
To evaluate system performance, samples were collected from the wellhead, across the treatment plant,
during oxidation/filtration vessel backwash, and from the distribution system.  Table 3-3 presents the

sampling schedules and analytes measured during each sampling event. 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, 2007). The procedure
for arsenic speciation is described in Appendix A of the QAPP.

3.3.1       Source Water. During the introductory meeting on November 30, 2006, one set of source
water samples was collected from Well No. 2 and speciated using an arsenic specitation kit (see Section
3.4.1). The sample taps were flushed for several minutes before sampling; special care was taken to avoid
agitation, which might have caused unwanted oxidation.  Analytes for the source water samples are listed
in Table 3-3.

3.3.2       Treatment Plant Water. The first treatment-plant sampling event occurred on December
17, 2008, when samples were collected for only total metal analysis. The next sampling event occurred
on January 22, 2009, during Battelle's site visit and operator training. Since then through the end of the
performance evaluation study, treatment plant water samples were collected from weekly to monthly,
somewhat different from the schedule laid out in the Battelle Study Plan (2008).  The Study Plan called
for weekly sampling, with "speciation sampling" performed during the first week of each four-week cycle
at the wellhead (IN), after the two pre-oxidation vessels (AP), and after the adsorption vessel (TC); and
"regular sampling" performed during the second, third, and fourth weeks at IN, after Pre-oxidation Vessel
A (TA), after Pre-oxidation Vessel B (TB), and TC. Speciation sampling included onsite speciation for
total and soluble arsenic, iron, manganese,  and titanium, and a suite of analytes as listed under
"Speciation Sampling" in Table 3-3; regular sampling included total arsenic, iron, manganese, and
titanium and silica, turbidity and alkalinity as listed in Table  3-3.

Actual speciation sampling occurred monthly, with three  exceptions for the month of June 2009 and June
2010 (with two speciation sampling events taking place in each month) and the month of August 2010
(with no speciation sampling taking place).  Actual regular sampling occurred as called for by the Study
Plan from February 22, 2009, through November 18, 2009, except for the weeks of July 21 and
November 11, 2009, when no sampling took place during these two weeks.  Regular sampling was
discontinued during the months of December 2009 and January 2010 but resumed in February 2010 with
a monthly frequency until the end of the performance evaluation study.

Treatment plant water samples were collected at IN, TA,  TB, AP, and TC from December 17, 2008,
through February 18, 2009, and at IN, AP, and TC thereafter (except for the week of March 10,  2009,
when samples were taken from  IN, TA, TB, and TC).

Beginning on April 19, 2010, only total arsenic, iron, manganese, and titanium were analyzed during each
regular sampling event.

3.3.3       Backwash Wastewater and Solids. The plant operator collected backwash wastewater
samples from each oxidation/filtration vessel on 12 occasions. During backwash, a side stream  of
backwash wastewater was directed from the tap on the backwash water discharge line to a clean, 32-gal
plastic container at approximately 1 gpm (Figure 3-1).  After the contents in the container were
thoroughly mixed, one aliquot was collected as is and the other filtered with 0.45-(im disc filters. The
samples were analyzed for analytes listed in Table 3-3.

Once during the study period, the contents in the 32-gal plastic container were 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 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       Spent Media. The media in the oxidation/filtration and adsorption vessels were not
replaced during this demonstration study, therefore, no spent media were produced as residual solids.

3.3.5       Distribution System Water. Water samples were collected from the distribution system to
determine the impact of the arsenic treatment system on the water chemistry in the distribution system,
specifically, the arsenic, lead and copper levels. Prior to the system startup from July 16 to September 2,
2008, four sets of baseline distribution system water samples were collected at three locations (845 West
8700 South House, 845 West 8700 South No. 1, and 845 West 8700 South No. 2).  Following system
startup, distribution system sampling continued periodically at the same sampling locations.

The plant operator collected the samples following an instruction sheet developed in accordance with the
Lead and Copper Monitoring and Reporting Guidance for Public  Water Systems (EPA, 2002). The date
and time of last water usage before sampling and of actual sample collection were recorded for
calculation of stagnation time. All samples were collected from a cold-water faucet that had not been
used for 6 hr or greater to ensure that stagnant water was sampled.

3.4.1       Preparation of Arsenic Speciation Kits.  The arsenic field speciation method used an anion
exchange resin column to separate the soluble arsenic species, 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 EPA-endorsed QAPP (Battelle, 2007).

-------
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, color-coded label consisting of 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 a specific water facility, sampling date, a two-letter code for a specific
sampling location, and a one-letter code 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-lock bags and packed in the cooler.

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 included.
The chain-of-custody forms and air bills 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 verified that all samples indicated on the chain-of-custody forms were included and intact.
Sample IDs were checked against the chain-of-custody forms, and the samples were logged into the
laboratory sample receipt log.  Discrepancies noted by the sample custodian were addressed with the plant
operator by the Battelle Study Lead.

Samples for metals analyses were stored at Battelie's inductively coupled plasma-mass spectrometry
(ICP-MS) laboratory. Samples for other water analyses were packed in separate coolers and picked up by
couriers from American Analytical Laboratories (AAL) in Columbus, OH, which was 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 detail in  Section 4.0 of the EPA-endorsed QAPP (Battelle, 2007)
were followed by Battelle's ICP-MS laboratory and AAL. 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
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
VWR Symphony SP90M5 Handheld Multimeter, 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 Symphony SP90M5 probe in the beaker
until a stable value was  obtained.

Facility Description and Pre-existing Treatment System Infrastructure
HSMHP is located at 845 West 8700 South in Willard, UT. The facility is a community water system
(CWS) supplied by two artesian wells, i.e., Wells No. 1 and No. 2. Well No. 1 has not been used for the
past 10 years and is intended only as a backup well.  Designated for this demonstration study, Well No. 2
served a population of 110 to 125 residents.  Prior to the study, this well typically operated 5 to 6 hr/day
to meet the average daily demand of approximately 11,000 gal.

Well No. 2 was 10-in in diameter and 288 ft deep with a screened interval extending from 200 to 250 ft
below ground surface (bgs). The static water level was 8 ft bgs. The well was equipped with a 2-
horsepower (hp) submersible pump rated for 30 gpm. The pre-existing Well No. 2 pump house was a 8 ft
x 10 ft x 8 ft wooden shed (Figure 4-1), which housed the wellhead cavity, piping, and a sample tap
(Figure 4-2). Various instrumentation, including pressure gauges and a wellhead totalizer, also was
located inside the pump house.  There  was no pre-existing treatment at this site.  Two hydropneumatic
tanks (Figure 4-3) were used to maintain the line pressure at 35 to 60 lb/in2 (psi). Water entered  the
distribution system via a 500-gal underground storage tank (that was also pressurized).
                                                                       ?;-X   3

4.1.1       Source Water Quality. Source water samples from Well No. 2 were collected on November
30, 2006, when Battelle staff traveled to the site to conduct an introductory meeting for this demonstration
project. The source water was filtered for soluble arsenic, iron, manganese, and antimony, and then
speciated for As(III) and As(V) using field arsenic speciation kits.  In addition, pH, temperature, DO, and
ORP also were measured onsite using a field meter.  Table 4-1 presents analytical results from the source
water sampling, which are compared to the data provided by EPA and Utah DDW.  Table 4-2 presents
year 2000 to 2005 source water quality data provided by Utah DDW.

Several factors, such as arsenic concentration and species, natural iron concentration, pH, natural organic
matter, and competing anions, affected the treatment train chosen. The results of the source water
assessment and implications for water treatment are discussed briefly below.

Arsenic. Historically, total arsenic concentrations of source water ranged from 13 to 14 |og/L. Based on
Battelle's sampling results, out of 15.4 |o,g/L of total arsenic, 1.8 |o,g/L existed as particulate arsenic. For
the soluble fraction, 6.0 |o,g/L existed as As(III) and 7.6 |o,g/L existed as As(V). A pre-oxidation step,
therefore, was needed to convert soluble As(III) to soluble As(V) for more effective arsenic removal. No
prior information on arsenic speciation was available. Battelle and EPA's total arsenic results were
slightly higher and lower, respectively, than the historical range provided by Utah DDW.

Iron and Manganese.  No historical data on iron concentrations existed.  Battelle's data indicated that,
out of 332 |og/L of total iron measured (which was over the  300-|o,g/L secondary maximum contaminant
level [SMCL]), only 129 |o,g/L (or 38%) existed as soluble iron, which was about 10 times higher than
soluble arsenic. EPA's March 20, 2006 sampling event indicated 213 |o,g/L of iron in raw water, which
was slightly lower than Battelle's data (EPA's data did not include soluble iron concentration).
Manganese concentrations of 130 and 180 |o,g/L obtained by EPA and Battelle, respectively, also exceed
the SMCL of 50 |o,g/L. The presence of iron and manganese as well as soluble As(III) in raw water
required pre-oxidation of water prior to Adsorbsia™ GTO™ adsorption.

Competing Anions. Depending on the treatment technology, removal of arsenic potentially can be
influenced by competing anions such as silica and phosphorus. Concentrations of silica at 13.3 to 13.4
mg/L (as SiO2) in raw water is not considered high enough to impact adsorption by Adsorbsia™ GTO™
                                               16

-------
media. Phosphorus concentrations were 0.2 mg/L (as PO4) or 0.4 mg/L (as P) based on EPA data. This
level of phosphorus could impact arsenic removal by iron-based media, but not by Adsorbsia™ GTO™
according to the media manufacturer, The Dow Chemical Company (Dow).

Other Water Quality Parameters. Battelle's data indicate a moderate pH of 7.5, which is within the
commonly-agreed target range of 5.5 to 8.5 for arsenic removal. The raw water samples also were
analyzed for additional parameters as listed in Tables 4-1 and 4-2. Collectively, total hardness
concentrations ranged from 108 to 112 mg/L (as CaCO3); turbidity from 1.4 to 2.6 nephelometric
turbidity unit (NTU); total dissolved solids (TDS) from 172 to 288 mg/L; nitrate from 0.2 to 0.3 mg/L;
barium from 0.07 to 0.12 mg/L; selenium from <0.5 to 0.9 |o,g/L; and sodium from 28 to 48 mg/L.  All
other analytes were below detection limits and/or anticipated to be low enough not to adversely affect the
arsenic removal process.

4.1.2       Distribution System. The distribution system for HSMHP consisted of 46 connections.
According to the park owner, the distribution system material is comprised of 2-in diameter galvanized
main with %-in galvanized connections to each home.  Three residences within the mobile home park
were selected for monthly baseline and distribution system water sampling to evaluate the effect of the
treatment system on the distribution system water quality.

For compliance purposes, HSMHP samples water periodically from the distribution system for several
parameters: monthly for bacterial analysis; yearly for nitrate; once every three years for lead and copper,
volatile organic compounds (VOCs), and inorganics; and once every three to five years for pesticides.

4.2        Treatment Process Description

4.2.1       Technology Description. Adsorbsia™ GTO™ media was proposed by Filter Tech to remove
arsenic at HSMHP. To  protect the media from fouling and to extend media life, a decision was made to
pretreat iron and manganese and to oxidize soluble As(III) to soluble As(V).  Because HSMHP preferred
not to use any chemicals, such as chlorine, to oxidize and disinfect water due to its concerns over
changing the taste of water and chemical handling, a pretreatment system of Birm® over Filox™ was
added to the originally proposed Adsorbsia™ GTO™ system. The use of an iron sequester, such as
polyphosphate, had been suggested,  but not adopted because it would not oxidize soluble As(III) and
could potentially impact arsenic adsorption with Adsorbsia™ GTO™. Based upon results of a pilot study
conducted at Licking Valley High School in Newark, OH under a separate EPA Task Order, EPA/Battelle
proposed to use the dual oxidizing media, Birm® and Filox™, to remove iron and manganese and
simultaneously oxidize soluble As(III) in source water.  Upon acceptance of the approach by all project
stakeholders, including UTAH DDW, HSMHP, and Filter Tech, Filter Tech revised its original design to
include Birm®/Filox™ as a pretreatment.

The treatment system at HSMHP consisted of two steps: oxidation/filtration of iron and manganese and
oxidation of soluble As(III) with Birm® and  Filox™ followed by adsorption of soluble As(V) with
Adsorbsia™ GTO™.  Backwashing as frequently as daily would be required to remove iron and
manganese solids accumulated in the Birm® and Filox™ media bed and maintain the effectiveness of the
media. This high backwashing frequency was considered important because of the high levels of iron and
manganese.  After the oxidation of soluble As(III), water containing soluble As(V) was introduced
downward through the Adsorbsia™ GTO™ bed.  When the media reached its capacity, the spent media
would be removed and subject to EPA's Toxicity Characteristic Leaching Procedure (TCLP) before
disposal. The media life depends upon soluble As(V) concentration, pH, and concentrations of competing
anions in source water.
                                              17

4.2.2       Birm* and Filox™.  Birm® is an acronym that stands for the "Burgess Iron Removal
Method" and is a proprietary product manufactured by the Clack Corporation (Windsor, Wisconsin).
Birm® is produced by impregnating manganous salts to near saturation on aluminum silicate sand, a base
material, followed by oxidizing manganous ions to solid manganese dioxide using potassium
permanganate. Filox  is a brand name for pyrolusite, a naturally-occurring manganese dioxide (MnO2)
in granular form. Both media can oxidize soluble Fe(II) and soluble Mn(II) and trap precipitated particles
in media beds. Both media have NSF International (NSF) Standard 61 approval for use in drinking water.
Table 4-3 presents physical and chemical properties of Birm® and Filox  .  When used in a mixed bed,
Filox™ stays in the lower half of the bed and Birm® over the upper half because the density of Filox™ is
over double the density of Birm®.  As well water is applied downward through the bed, Birm® will
oxidize most of the soluble Fe(II) and soluble Mn(II), leaving soluble As(III) to be oxidized by Filox  .
This is based on observations made during the above-mentioned pilot study.

4.2.3       Adsorbsia™ GTO™ Media. Adsorbsia™ GTO™ is a white, free flowing granular titanium
oxide-based media manufactured by Dow.  The media is capable of adsorbing both soluble As(V) and
soluble As(III), with a higher capacity for soluble As(V).  Commonly mentioned adsorption pH values
range from 6.5 to 8.5, but the adsorption is less effective at the upper end of the range. According to
Dow, the media capacity for arsenic may be independent of anions such as sulfate, phosphate, and
vanadium.  However, the presence of silica can reduce arsenic removal. Adsorbsia™ GTO™ is designed
for non-regenerative applications. When exhausted, it is removed from the vessel and replaced with
virgin media.  Spent media from Dow's arsenic loading tests have been shown to pass both the TCLP and
California Waste Extraction Test (CA WET). Table 4-4 presents physical and chemical properties of
Adsorbsia™ GTO™.  The media is NSF/ANSI 61 certified and delivered in dry granular form.

4.2.4       System Design and Treatment Process. The 30-gpm treatment system consisted of two
Birm®/Filox™ vessels, one Adsorbsia™ GTO™ vessel, one  backwash water supply tank, and two pressure
tanks (pre-existing).  Figure 4-4 presents a schematic of the treatment system.  Figure 4-5 shows as-built
cross  sections of a pre-oxidizing and an adsorption vessel. Table 4-5 specifies key system design
parameters of the treatment system.  Figure 4-6 shows a process flowchart, along with the sampling/
analysis schedule. The key process components of the treatment system are discussed as follows:

       •   Intake - Raw water was fed to the treatment system by a 2-hp submersible pump with a
           maximum flowrate of 30 gpm.  The reported deadhead pump pressure was 50 psi (on
           average), based on a pre-existing pressure gauge installed at the wellhead. A pre-existing
           flow meter/totalizer was used to monitor flowrates and volume throughputs.  A sample tap
           was used to collect raw water samples for chemical analysis.

•   Pre-Oxidation - Prior to adsorption, raw water was allowed to flow through two 24-in x 72-
    in, in-parallel composite vessels, each containing 19 in of Birm® and 19 in of Filox™. At a
    design flowrate of 15 gpm/vessel, it corresponds to a filtration rate of 4.8 gpm/ft2, which is
    within the recommended range of 3 to 5 gpm/ft2.  During media backwashing, a 15-gpm/ft2
    backwash rate was applied to the bed, resulting in >40% and <10% bed expansion for Birm®
    and Filox™, respectively. These anticipated bed expansions were well within the 30 in
    available freeboard in each pre-oxidation vessel (actual freeboard was <30 in).
    The anticipated pressure drop across a clean bed was 4 psi, and the maximum pressure drop
    allowed was 14 psi. Pressure gauges and sample taps located before and after each pre-
    oxidation vessel were used to monitor pressure drop and effectiveness of pre-oxidation,
    respectively.  Flowrates and volume throughputs of filtered water were monitored with two
    1 !/2-in Signet battery-operated insertion turbine meters/totalizers located on the effluent side
    of the two pre-oxidation vessels. Figure 4-7 shows the two pre-oxidation vessels (Vessels A
    and B) and one adsorption vessel (Vessel C) and piping connections. Figure 4-8 shows the
    programmable logic controller (PLC) panel with a close-up view of the touch screen for the
    filter operation.

•   Adsorption - Following pre-oxidation, water was fed to a 24-in x 72-in composite vessel
    containing 10 ft3 of Adsorbsia™GTO™ underlain by 2 ft3 of garnet.  At the design flow rate of
    30 gpm, the empty bed contact time (EBCT) was 2.5 min and the hydraulic loading rate was
    9.5 gpm/ft2. The anticipated pressure drop across a clean bed was 8 psi, and the maximum
    pressure drop was  18 psi. Flowrates and volume throughputs of treated water were monitored
    using a 1 !/2-in Signet battery-operated insertion turbine meter/totalizer located on the effluent
    side of the vessel.  The head loss across the vessel was monitored by a pair of pressure
    gauges. A strainer (Figure 4-9) was installed before the adsorption vessel to capture fines
    exiting the pre-oxidation vessels.  Sample taps were located before and after the pressure
    vessel to allow for the collection of water samples for chemical analyses.

•   Pressure Tanks - Treated water from Vessel C was temporarily stored in the two pre-
    existing pressure tanks (Figure 4-3) in the Well No. 2 pump house.  These pressure tanks
    were  used to maintain the line pressure between 35 and 60 psi.

•   Filter Backwash - Frequent backwashing was required to maintain performance of the pre-
    oxidizing media. Upon initiation by a time setpoint, backwash was done with Birm®/Filox™-
    treated water stored in a 550-gal poly tank (Figure 4-10).  During system startup and
    shakedown, programming changes were made to include a time delay between
                                       19

completion of pre-oxidation vessel backwash and return of the freshly backwashed vessels to
service (to fill the 550-gal backwash supply tank first [see discussion in Section 4.3.3]). By
design, each pre-oxidation vessel was to be backwashed daily at 47 gpm for 8 min, producing
376 gal of wastewater per vessel.

The AM vessel was backwashed as needed. Once initiated, the vessel was backwashed at 27
gpm for 8 min, producing 216 gal of wastewater. The wastewater produced was discharged
to a septic system behind the treatment building (Figure 4-11). No permit was needed to
discharge the  backwash wastewater to the septic system.

Media Replacement. When arsenic concentrations in Adsorbsia™ GTO™-treated water
approaches 10 |og/L, replacement of the media will be necessary. Based on the estimate
provided  by the vendor, breakthrough of arsenic at 10 |o,g/L would be expected after treating
approximately 168,000 BV of water.  The spent media can be disposed of as non-hazardous
waste in a sanitary landfill if it passes the EPA's TCLP. During the performance evaluation
study, neither the media in the pre-oxidation nor the adsorption vessel required a changeout.

4.3.1       Permitting. For the permit application, Filter Tech prepared an engineering package,
including design drawings and a process description of the proposed treatment system.  After it was
reviewed and signed by a Utah-licensed professional engineer (Hansen, Allen & Luce, Inc.), the package
was submitted to and approved by Utah DDW on July 7 and August 7, 2008, respectively.

Following installation of the treatment system, Hansen, Allen & Luce, Inc. submitted an operating permit
request (that included final as-built drawings and bacteria test results) to Utah DDW. Utah DDW issued
on December 11, 2008, a temporary permit, which stipulated a monitoring and a quarterly reporting
requirement and remained effective through December 31, 2009. As opposed to a permanent permit, the
temporary permit was issue because Utah DDW needed to evaluate the data to be generated during the
EPA demonstration study and determine an appropriate monitoring schedule. The operator obtained a
permanent permit before the temporary permit had expired.

4.3.2       Building Preparation. To house the new treatment system, a 10-ft * 10-ft * 8-ft
prefabricated metal structure with a 6 ft * 6 ft roll-up door (Figure 4-12) was installed on a concrete pad
poured in late August 2008. The building installation began on September 6, 2008, and was completed
on September 11,2008.

4.3.3       Installation, Shakedown, and Startup. Installation of the treatment system began on
September  16, 2008.  Installation  activities included offloading, placing, and connecting the pre-
oxidation/adsorption vessels to influent, effluent and backwash tie-in points, and completing electrical
wiring for system controls. Several trips were required to complete the installation due to an inaccurate
estimate of the building height. The original system piping was pre-fabricated based on a ceiling/wall
height of 8  ft. Although the ceiling height was 8 ft, the walls were several feet shorter, resulting in
insufficient clearance over the vessels for the rigid, pre-fabricated piping to fit in. Therefore, flexible
tubing had to be used, instead, for vessel inlet and outlet connections (Figure 4-13).  The pre-
                                             27

oxidation/adsorption vessels and a backwash pump were bolted to the floor with concrete anchors and
pipe supports mounted to ceiling joints.

Media Loading.  A slotted polyvinyl chloride (PVC) underdrain was installed in the bottom of each
vessel with a l!/2-in Schedule 40 standpipe. Two ft3 of garnet (%-in x Mrin), 5 ft3 of Filox™, and 5 ft3 of
Birm® were then loaded sequentially through a 4-in opening at the top of each pre-oxidation vessel.  The
amount of garnet was enough to cover the underdrain.  The depth of each media layer was measured at
approximately 19.7 in, close to the calculated value of 19.1 in based on the media volume and vessel
diameter.

On October 4, 2008, 2 ft3 of garnet and 10 ft3 of Adsorbsia™ GTO™ were loaded into the adsorption
vessel. The media depth was measured at approximately 39.4 in, close to the calculated value of 38.2 in
based on the media volume and vessel diameter. Freeboard was measured from the top of the vessel to
the top of the media layer to ensure sufficient room for backwashing. The freeboard measured was 20 in
in the pre-oxidation vessels and 21 in in the adsorption vessel.  Although smaller than the design values of
30 and 28 in, respectively  (see Table 4-5), these freeboards provided more than 50% of bed expansion,
sufficient to meet media backwashing needs.

Media Backwashing. To prepare for media backwashing, the 550-gal backwash supply tank was first
filled with well water via piping that bypassed the treatment system (see Figure 4-14).  Because the well
water contained a large amount of silt, a layer of sediment was found to deposit at the bottom of the tank.
Therefore, the piping to the tank had to be disconnected and the tank was rinsed out. The tank was then
refilled to approximately 460 gal.
                      Figure 4-14. Backwash Supply Tank and Inlet Piping
The pre-oxidation vessels were backwashed manually one at a time. Backwash flowrates were controlled
by throttling a 2-in PVC ball valve on the backwash line. The initial flowrate to a vessel was 8.5 gpm,
which was maintained until the vessel was completely filled.  Afterwards, the flowrate was incrementally
increased to 20, 38, and 47 gpm (or 6.4, 12.1, and 15.0 gpm/ft2).  The flowrate was then kept steady at 47
gpm until the backwash supply tank was almost empty. The amount of water in the backwash supply
tank (460 gal) was enough to allow for a complete backwash cycle at the design flowrate of 47 gpm and
the design duration of 8 min.

-------
Each pre-oxidation vessel was backwashed five times over a two-day period on October 22 and 23, 2008.
Although the backwash effluent was never completely cleared up after the five backwashes (Figure 4-15),
the vessel effluent looked clear, indicating a clean bed.  The total amount of water used for backwash was
5,206 gal.  The freeboard measured in both vessels after the fifth backwash was 21 in, indicating the loss
of approximately 1 in of media during backwash. The new bed depth was 18.7 in.
        Figure 4-15. Wastewater Collected After First (left) and Fifth Backwashes (right)
To prepare Adsorbsia™ GTO™ media for backwashing, the backwash supply tank was cleaned and refilled
with 430 gal of treated water from the newly backwashed pre-oxidation vessels. The 430 gal of water in
the backwash supply tank would last for 16 min (or twice the design duration) if the backwash flowrate
was maintained at the design flowrate of 27 gpm.

The Adsorbsia™ GTO™ startup procedure called for backwashing the media with 75 to 90 BV (5,610 to
6,732 gal) of water at 6 to 10 gpm/ft2 (or 18.9 to 31.4 gpm). After filling the vessel at 6 gpm (or 2
gpm/ft2), the backwash flowrate was set at 14.5 gpm to determine if this flowrate would result in media
loss. During the first backwash (with approximately 430 gal of water), some media loss was observed;
the backwash flowrate was therefore reduced to 10 gpm. After three and six backwash cycles (each with
approximately 430 gal of water), the flowrate was increased to 19 and 27.5 gpm (or 6.1 and 8.8 gpm/ft2),
respectively.  Upon completion of the twelfth backwash, backwash wastewater had gone from milky
(after the initial backwash) to cloudy (Figure 4-16) and a total of 5,558 gal (or 74.3 BV) of water had
been used for backwash. The vessels were backwashed one more time in preparation of disinfection. At
this point, a total of 12,233 gal of water had been used to backwash all three vessels.

Because the freeboard in the adsorption vessel was not re-measured after backwash, the pre-backwash
bed depth of 39.4 in was used to calculate BV, which was 10.3 ft3 or 77.1 gal.  This bed depth also was
shown in the as-built cross section drawing in Figure 4-5.

Vessel Disinfection.  The two pre-oxidation and one adsorption vessels were disinfected using a 185
mg/L (as C12) sodium hypochlorite (NaOCl) solution, prepared by adding 1.4 gal of Clorox® bleach
(containing 6% NaOCl) into 500 gal of treated water in the backwash supply tank. After 140 gal of the

chlorine solution was pumped upflow through each vessel at 6 gpm, the vessels were allowed to sit
overnight. Because the effluent from each vessel contained only a trace level of chlorine residuals, the
disinfection procedure was repeated.  Upon applying additional 100 gal of the chlorine solution through
each vessel, greater than 20 mg/L (as C12) of chlorine residuals were measured in the vessel effluent. The
vessels were then rinsed with well water in the service mode (i.e., parallel through the pre-oxidation
vessels and then the adsorption vessel) until chlorine residuals in the vessel effluent were below its MDL.
A sample was collected downstream of the Adsorbsia™ GTO™ vessel for the Bac-T test.

Startup Issues.  Soon after system startup on December 11, 2008, it was noted that when the system
pressure became  low, the normally closed, hydraulically-operated diaphragm valves on the backwash line
would open (due to lack of pressure on the diaphragm to close the valves), causing water to constantly
leak and bypass the treatment system. To alleviate this concern, a small bladder tank was installed on the
treated water line and filled with pressurized water from the distribution system and a check valve was
installed to keep the tank pressurized if there was a loss of pressure in the system. Meanwhile,
the hydraulic line supplying the diaphragm valves was taken after the check valve but before the tank so
that there was always enough pressure in the bladder tank to open and close the diaphragm
valves. During normal operation, the bladder tank was kept at the same pressure as the system. However,
when the well pump went into sleep mode or if the system lost pressure, the bladder tank would maintain
the normal system pressure and keep the diaphragm valves closed.

In addition, the backwash supply tank refill line was separated from the service line so that it would not
cause the variable frequency drive (VFD) pump to run at a higher flowrate during refill of the backwash
supply tank.  This modification reduced the well pump flowrate from approximately 30 to  20 gpm during
refill of the backwash supply tank.

Issues Observed During Battelle's Site Visit. On January 21, 2009, two Battelle staff members visited
the site to inspect the system and provide operator training on the data and sample collection. When
onsite, the system was backwashed for observation and residual sampling. Table 4-6 summarizes PLC
settings and measurements taken during backwash. Table 4-7 presents flowrates measured during refill of
the backwash supply tank. The time delay between Vessels A and B backwashing was initially set at
2,150 sec (~36 min) for the backwash supply tank to be refilled. Since it took only 1,660 sec (~27 min) to
refill the tank, the time delay was shortened to 1,800 sec (30 min). The 27 min refill time was based on a
refill flowrate of 13 gpm.  Based on the data presented in Table 4-7, refill flowrates could be as high as
17.2 gpm. Therefore, the refill time could be as short as 21 min.

Samples of backwash wastewater were collected at the backwash discharge point at the beginning, during,
and the end of pre-oxidizing media backwashing.  These samples were collected for visual observation of
water quality and signs of media loss. As shown in Figure 4-17, all three samples looked cloudy but
contained little media. This suggests that the media needed to be backwashed more frequently than
weekly and that bed expansion during backwash was within the available freeboard height. Water
samples collected at the AP sampling location during refill of the backwash supply tank also were cloudy
and contained a small amount of media (see photographs in Figure 4-18 for a water sample taken at AP
versus a water sample taken at IN).  This indicates that the pre-oxidizing media had not been thoroughly
cleaned during backwashing and that the media was not given enough time to settle prior to being put
back into service to refill the backwash supply tank.

Based on the above-mentioned and other observations made during the site visit, a punch list was
developed and discussed with Filter Tech. Punch-list items included the following:

       •   Install a sediment filter prior to the inlet flow totalizer
                                            32

       •   Set timer to backwash daily
       •   Supply a revised schematic that reflects all system modifications that have been made
       •   Install a new backwash sample tap
       •   Develop a plan for backwashing Tank C.

Filter Tech ordered materials and parts and returned to the site on April 18 to 19, 2009 to complete all
punch-list items mentioned above. While onsite, a separate backwash supply line to Tank C was installed
to allow backwashing of Tank C. Tank C was backwashed; the backwash discharge showed no sediment
buildup.

4.4         System Operation

4.4.1       Operational Parameters.  The operational parameters for the demonstration study were
tabulated and are attached as Appendix A.  Table 4-8 summarizes key parameters. The performance
evaluation study began on December 11, 2008, and ended on October 18, 2010. During the study period,
the well pump operated for a total of 15,835 hr, averaging 23.4 hr/day (for 676 days).  The well pump ran
almost around the clock, occasionally going into a sleep mode.

As noted in Section 4.2, flowrates and volume throughputs were tracked by five Signet insertion turbine
flow meters/totalizers located separately at the system inlet, after Vessels A, B, and C, and on the
backwash water supply line. The inlet flow meter/totalizer stopped registering incoming flow on March
30, 2010, rendering it useless for tracking the system flow.  The flow meter/totalizer on Vessel A was not
installed until April 9, 2009; therefore, the flow through Vessel A prior to this date was estimated by
subtracting the flow through Vessel B from the flow through Vessel C. Although not done, this amount
should have been further adjusted by adding half of the flow used to refill the backwash supply tank prior
to April 9, 2009.

In theory, the inlet flow should be equal to the sum of the flow through Vessels A and B and equal to the
sum of the flow through Vessel C and the flow to refill the backwash supply tank.  Based on the meters/
totalizers installed on the three vessels, the total amount of water treated by the two pre-oxidation vessels
was 5,198,000 gal (including 2,571,000 and 2,627,000 gal through Vessels A and B, respectively); the
total amount of water treated by the adsorption vessel (Vessel C) was 5,629,000 gal. Instead of being
lower,  this amount (5,629,000 gal) was actually higher than the total flow through both pre-oxidation
vessels. While it was not clear what had caused this to occur, the way the flow meters/totalizers were
installed (i.e., flexible hoses with short straight length) could contribute, in part, to the discrepancies
observed. As specified by the meter manufacturer, depending on the piping configurations, the straight
length  upstream from the flow sensor should be 10 to 50 times (15 to 75 in) the inner  diameter of the  pipe
and the straight length downstream from the flow sensor should be at least five times  (7.5 in) the inner
diameter of the pipe. With all piping/valves/meters/gauges installed in a rather congested area as shown
in Figure 4-7, these requirements most likely were not met.  The other possible cause  was the ability of
the flow meters/totalizers to register flow with <4 gpm flowrates. This is discussed in detail in Section
4.4.3.

Based on the Vessel C flow meter/totalizer,  the system treated 5,629,000 gal (or 73,000 BV) of water
(bed volumes were calculated based on 10.3 ft3 [or 77.1 gal] of media).  Daily demands through the entire
study period ranged from 2,476 to 21,987 gal and averaged  8,354 gal, which was 24% lower than the
11,000 gpd provided by the operator prior to the demonstration study.

           (a)  Vessel A totalizer installed on April 9, 2009; throughput prior to April 9, 2008,
               calculated based on Vessels B and C totalizer readings.
           (b)  Calculated based on 10.3 ft3 (or 77.1 gal) of media in vessel.
Instantaneous flowrates through Vessels A and B (as read from the respective Signet flow meters)
fluctuated extensively from 0.6 to 20.9 gpm.  Instantaneous flowrates through Vessel C also fluctuated
extensively from 0.7 to 24 gpm.  The higher flowrates occurred when the backwash supply tank was
being filled, either from the combined effluent of Vessels A and B or from the effluent of Vessel C. The
fill rate to the backwash supply tank was controlled by a PVC ball valve and could be manually
adjusted. The fill rate was set to be less than the system maximum flowrate because pumping at a high
flowrate over an extended period could cause an increase in the sediment content in well water.

The average flowrate through the two pre-oxidation vessels was 9.3 gpm; the average flowrate through
the adsorption vessel was 7.3 gpm. These flowrates were much lower than the 30-gpm design value as
shown in Table  4-5. At these average flowrates, hydraulic loading rates were 1.4 and 2.3 gpm/ft2,
respectively (compared to the design values of 4.8 and 9.5 gpm/ft2, respectively). EBCTs with the AM
ranged from 3.2 to  110 min and averaged 10.6 min, which was four times the vendor-recommended
EBCT of 2.5 min.
                                             35

-------
System inlet pressure readings ranged from 50 to 92 psi averaging 61 psi.  Pre-oxidation outlet pressure
readings ranged from 40 to 98 psi, averaging 59 psi.  Differential pressure (Ap) across the pre-oxidation
vessels ranged from 0 to 20 psi and averaged 2 psi. These Ap readings reflect results of a daily backwash
schedule.  Ap across the adsorption vessel ranged from 0 to 22 psi and averaged 6 psi. These Ap readings
reflect results of one backwash on April 18, 2009 throughout the study period.

From December 11, 2008, through October 18, 2010, 511,800 gal of backwash wastewater was produced.
Assuming that daily backwash began on December 11, 2008, 676 backwashes would have been done by
the end of the study period.  Therefore, each backwash would have produced 776 gal of wastewater,
which is very close to the design value of 752 gal for both vessels (at 47 gpm for 8 min per vessel).

4.4.2      Residual Management. Residuals generated by the operation of the system included only
backwash wastewater. Neither the oxidation media (Birm®/Filox™) nor the AM (Adsorbsia™ GTO™)
were replaced during the study period.  The wastewater produced was discharged to the septic tank
behind the treatment building (Figure 4-11).  No permit was necessary to discharge the backwash
wastewater to the  septic system.

4.4.3      System/Operation Reliability and Simplicity. There were no major operational issues
affecting the system; only minor repairs were made to the system. Filter Tech made a site visit on June
13, 2009, to calibrate all flow meters/totalizers. The issue was that the  new flow totalizer on Vessel A
would not register flow when its flowrate was lower than 4 gpm.  This was unlike the flow meters/
totalizers on both Vessel B and the backwash water supply line that were capable of registering flow
down to 3 gpm due to the use of a more sensitive sensor.  Filter Tech switched the flow meter/totalizer on
Vessel A with one on the backwash water supply line so that both Vessels A and B had identical flow
meters/totalizers.  On August 25, 2009, and June 22, 2010, the operator took the system offline to replace
a leaking nut on the piping  leading to Vessel  B. The  system was offline for several days until the repair
work was complete.

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.

Pre- and Post-Treatment Requirements.  Pretreatment included oxidation/filtration with Birm®/Filox™
media for iron and manganese removal and soluble As(III) oxidation.  Iron and manganese particles
formed were backwashed out of media beds.  There was no post chlorination of the distribution water.

System Automation.  The Birm®/Filox™ and  Adsorbsia™ GTO™ system included automated controls for
service and backwash operations.

Operator Skill Requirements. Under normal operating conditions, the skills required to operate the
arsenic treatment system were minimal. The operator's duties were to monitor the pre-oxidation and
adsorption vessels, and initiate manual backwash when necessary.

Utah's Operator Certification Program is authorized by Section R3 09-105-11 of the Utah Public Drinking
Water Rules. The rules state that "all community and non-transient non-community water systems or any
public system that employs treatment techniques for surface water or ground water under the direct
influence of surface water shall have an appropriately certified operator."  The specific requirements are
located in Section 309-300, Certification Rules for Water Supply Operators.
                                             36

-------
All public drinking water systems within the state of Utah are assigned a complexity level (I, II, III, IV)
and discipline (Treatment or Distribution) for the certification requirements of their operators.  Any
operator who makes independent decisions that affect the sanitary quality, safety, and adequacy of the
water to their system needs to be certified to the grade of the system. HSMHP was classified as a
"distribution" facility and designated as a "small system" serving a population between 25 and 500
persons. Operators running a "small system" are required to obtain 2.0 continuing education units within
a three-year period to renew certification.

Preventive Maintenance Activities. Preventive maintenance tasks included such items as periodic checks
of flow meters and pressure gauges and inspection of system piping and valves.  Typically, the operator
performed these duties only when he was onsite for routine activities. The operator recorded flow,
volume, and pressure readings of the system daily.

Chemical/Media Handling and Inventory Requirements.  No chemical was used as part of the treatment
system at the HSMHP.

4.5     System Performance

The performance of the HSMHP arsenic removal system was evaluated based on analyses of water
samples collected from the treatment plant, the media backwash residuals, and distribution system.

4.5.1       Treatment Plant Sampling. Water samples were collected on 64 occasions, including three
duplicate events, with field speciation performed on 22 occasions at the IN, AP, and TC sampling
locations. TA and TB also were sampled seven times between December 17, 2008, and February 18,
2009, and on March 10, 2009, and then discontinued thereafter.  Sample location AP was not sampled on
March 10, 2009.

Table 4-9 presents a statistical summary of key  analytical results of arsenic species, total and soluble iron,
and manganese measured at the IN, AP, and TC sampling locations across the treatment train.  Table 4-10
summarizes the statistical summary of other water quality parameters at the same three locations.  The
analytical data at TA and TB were not used for the statistical analysis due to small sample sizes (i.e., 3 to
7).  Appendix B contains a complete set of analytical results for the demonstration study. The results of
the treatment plant sampling are discussed below.

Arsenic. The key parameter for evaluating the treatment effectiveness was the arsenic concentration in
treated water. Figure 4-19 contains three bar charts showing concentrations of arsenic species, including
particulate arsenic, soluble As(III), and soluble As(V) at the IN, AP, and TC locations for each of the 22
speciation events. Total arsenic concentrations  in source water ranged from 9.4 to 21.1 (ig/L and
averaged 13.2 (ig/L (Table 4-9). Of the soluble fraction, As(III) and As(V) each accounted for about half
of the concentration at 6.0 and 5.8 (ig/L, respectively (on average).  Except for one spike of 8.8  (ig/L on
September 23, 2009, particulate arsenic concentrations were low, averaging 1.3  (ig/L.

After the Birm®/Filox™ treatment, there was 21%  reduction in total  arsenic concentration to 10.4 (ig/L (on
average), indicating removal by Birm®/Filox™.  The remaining arsenic existed primarily as soluble As(V)
with concentrations ranging from 8.7 to 11.1 (ig/L and averaging 10.0 (ig/L. Soluble As(III) and
particulate arsenic concentrations were low, averaging 0.3 and 0.2 (ig/L, respectively (on average).
Therefore, the Birm®/Filox™ treatment was effective in oxidizing soluble As(III) to soluble As(V)
throughout the study period.

The Adsorbsia™ GTO™ media further removed  soluble As(V) to below the 10-(ig/L MCL.  Figure 4-20
presents total arsenic breakthrough curves from the pre-oxidation and adsorption vessels. By September
                                             37

14, 2010, when the last set of samples was collected, total arsenic concentrations in treated water after
Adsorbsia™ GTO™ had reached 6.2 (ig/L.  The amount of water treated at this point was 69,200 BV.

Iron. Total iron concentrations in raw water ranged from <25 to 871 (ig/L and averaged 276 (ig/L. The
soluble fraction ranged from 37 to 210 (ig/L and averaged 93 (ig/L.  Figure 4-21 presents total iron
concentrations at the IN, AP, and TC locations for all 64 sampling events.  Figure 4-22 contains three bar
charts showing concentrations of particulate and soluble iron at the IN, AP, and TC locations for each of
the 22 speciation events. The data indicated that iron was mostly removed to below the MDL of 25 (ig/L.
Iron solids accumulated in the Birm®/Filox™ bed were removed via daily backwashing, which was able to
maintain media performance without any signs of iron leakage or media fouling after close to two years
of service.

Manganese.  Figure 4-23 presents total manganese concentrations at the IN, AP, and TC locations for all
64 sampling events. Total manganese levels in source water ranged from 87.6 to 286 (ig/L and averaged
116 (ig/L, which existed almost entirely in the soluble form. Following the oxidation/filtration by
Birm®/Filox™, total manganese concentrations were reduced to 4.0 (ig/L (on average) with no

concentration over the 50-(ig/L MCL.  The data indicated that Birm®/Filox™ was effective in removing
manganese from raw water, preventing the downstream AM from being coated with MnO2.

Other Water Quality Parameters. Raw water pH values measured at the IN location varied from 7.4 to
8.0. pH values remained essentially unchanged after the dual oxidizing media treatment.  Alkalinity also
did not vary, with values ranging from 129 to 161 mg/L (as CaCO3) across the treatment train.  Treatment
plant samples were analyzed for fluoride, sulfate, nitrate, phosphorus, and hardness only when arsenic
speciation was performed. Fluoride and nitrate concentrations were low, averaging 0.1 and 0.2 mg/L (as
N), respectively, across the treatment train. Sulfate levels also were low, ranging from 3.2 to 7.1 mg/L
throughout the treatment train. Concentrations of total hardness, existing primarily as calcium hardness
(about 82%), ranged from 97 to 129 mg/L (as CaCO3), and remained essentially unchanged throughout
the treatment train. Silica (as SiO2) concentrations ranged from 13.3 to 18.0 mg/L, and appeared
unaffected by the treatment process.

Total phosphorus levels in raw water fluctuated between 57 and 170 (ig/L and averaged 112 (ig/L. The
pre-oxidation step removed 19 to 67% (40% on average) of total phosphorus, leaving 19 to 100 (ig/L in
the influent to the Adsorbsia™ GTO™ vessel.  Adsorbsia™ GTO™ further removed total phosphorus to <10
to 78 (ig/L. Figure 4-24 presents total  phosphorus breakthrough curves. Figure 4-25 plotted percentages
of total phosphorus removal by Birm®/Filox™ and Adsorbsia™ GTO™, respectively.  For the first 22,000
BV, Adsorbsia™ GTO™ removed up to 90% of total phosphorus in the vessel influent. However, the
removal followed a decreasing trend and was reduced to <20% after approximately 36,000 BV.

Total titanium was monitored throughout the treatment train to evaluate if any Adsorbsia™ GTO™ media
had gotten into the treated water in either a soluble or a particulate form.  Very little titanium was
                                              43

measured in raw water with concentrations averaging only 1.8 (ig/L.  Total titanium concentrations
following the adsorption vessel were low, ranging from 0.9 to 444 (ig/L and averaging 16.3 (ig/L.  There
were two instances where total titanium concentrations in the adsorption vessel effluent were high, i.e.,
268 (ig/L on March 10, 2009, and 444 (ig/L on November 18, 2009.  For the November 18, 2009, sample,
the turbidity reading also was uncharacteristically high (9.9 NTU), indicating leakage of media fines into
the vessel effluent. Soluble titanium concentrations remained at the background level of 1.4 (ig/L
throughout the treatment train.

4.5.2       Backwash Residual Sampling. Backwash wastewater samples were collected 12 times from
each of the Birm®/Filox™ vessels. Table 4-11 presents analytical results of the Birm®/Filox™ backwash
wastewater sampling. The  Adsorbsia™ GTO™ vessel was backwashed only once for a test purpose;
therefore, no samples were  collected during its backwashing.

As shown in Table 4-11, results for the two vessels were comparable. pH values of backwash wastewater
ranged from 7.5 to 7.9 and averaged 7.7, which was similar to that of the pre-oxidized water used for
backwashing. TDS concentrations ranged from 142 to 180 mg/L and averaged 164 mg/L. TSS
concentrations ranged from 13.0 to 86.0 mg/L and averaged 29.8 mg/L. TSS concentrations were low
because the pre-oxidizing media was backwashed daily.

The backwash wastewater samples contained 14.3 to 102 (ig/L of total arsenic, 632 to 5,421 (ig/L of total
iron, 180 to 1,422 (ig/L of total manganese, and 3.4 to 653 (ig/L of total titanium.  As expected, the
majority of these metals were present in the particulate form. Assuming that 752 gal of wastewater was
produced when backwashing the two pre-oxidation vessels and that the wastewater contained 29.8 mg/L
of TSS, it would discharge 85 g (0.2 Ib) of solids. The waste stream would consist of 102 mg of arsenic,
8.9 g of iron, and 1.6 g of manganese based on 35.8 (ig/L of total arsenic, 3,115 (ig/L of total iron, and
548 (ig/L of total manganese in the backwash wastewater. According to Table 4-9, concentration
differences between the IN and AP locations were 2.8 (ig/L of total arsenic, 276 (ig/L of total iron, and
112 (ig/L of total manganese (on average). Therefore, based on a daily water demand of 8,354 gal, the
pre-oxidation vessels would remove 88.2 mg of total arsenic, 8.7 g of iron, and 3.5 g of manganese from
raw water. The daily backwash recovered 116% of total arsenic, 102% of total iron, and 46% of total
manganese from the pre-oxidation vessels. The low Mn recovery rate might be attributed to the fact that
some manganese (existing as MnO2) had attached to the oxidation media surface and was difficult to be
washed off.

One set of backwash solid samples was collected on June 29, 2009 and analyzed in duplicate for ICP/MS
metals.  Table 4-12 presents the results of total metals analysis.

Samples collected on 06/20/09; units in |ag/g.
Total arsenic, iron, and manganese concentrations in the solids averaged 113, 40,319, and 15,008 (ig/g.
Assuming that the daily backwashing discharged 85 g of solids (dry weight), the solids would contain 9.6
mg of total arsenic, 3.4 g of total iron, and 1.3 g of total manganese.  The amounts of total arsenic and
iron were much lower than the values calculated based on the backwash wastewater data.

4.5.3       Distribution System Water Sampling. Prior to the installation/operation of the treatment
system, four first-draw baseline distribution system water samples were collected at three locations, i.e.,
South House, South #1, and South #2, on July 16, August 13, August 20, and September 2, 2008.
Following the installation of the treatment system, distribution water sampling continued on a monthly
basis from January 2009 to November 2009. Table 4-13 presents results of the distribution system water
sampling.

The most noticeable change in the distribution samples since system startup was a decrease in arsenic,
iron, and manganese concentrations. Baseline arsenic concentrations ranged from 10.0 to 14.2 (ig/L and
averaged 11.2 (ig/L. After system startup, arsenic concentrations were reduced to 0.3 to 6.0 (ig/L and
averaged 3.2 (ig/L. Baseline iron concentrations ranged from less than the MDL of 25 (ig/L to 391 (ig/L,
and averaged 70 (ig/L. After system startup, iron concentrations decreased to <25 (ig/L (on average).
Manganese had a similar trend with baseline concentrations averaging 19.5 (ig/L and after-startup
concentrations averaging 8.8 (ig/L.

Lead and copper concentrations of all water samples collected before and after the installation of the
treatment system were below the action level of 15 and 1,300 (ig/L, respectively. The arsenic treatment
system did not seem to have any effects on the lead or copper concentrations in the distribution system.

Measured pH values in distribution water ranged from 7.4 to 8.0 and averaged 7.7. Alkalinity levels
ranged from 134 to 148 mg/L (as CaCO3). The arsenic treatment system did not affect these water quality
parameters of the distributed water.

4.6        System Cost

The system cost 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.  Capital  cost of the treatment system included the expenditure
for equipment, site engineering, and system installation, shakedown, and startup. O&M cost included the
expenditure for chemicals, electricity, and labor.  Cost associated with the building was not included in
the capital cost because it was outside the scope of this demonstration project and was funded separately
bytheHSMHP.

4.6.1       Capital Cost.  The capital investment for the Birm®/Filox™ pre-oxidation and Adsorbsia™
GTO™ arsenic removal was $66,362 (Table 4-14).  The equipment cost was $46,267 (or 70% of the total
capital investment), which included costs for three 24-in  x 72-in composite vessels, 10 ft3 each of Birm®,
Filox™, and Adsorbsia™  GTO, 6 ft3 of garnet underbedding support, one backwash supply system, process
valves and piping, instrumentation and controls, shipping, and labor.

The site engineering cost covered the expenditure  for preparing the required engineering  submittal,
including a process design report, a general arrangement drawing, piping and instrumentation diagrams
(P&IDs), electrical diagrams, interconnecting piping layouts, and obtaining the required permit approval
from Utah DDW. The engineering cost of $3,850 was 6% of the total capital investment.


The installation, shakedown, and startup cost covered the labor and materials required to  unload, install,
and test the system for proper operation. The installation, startup and shakedown activities were
performed by Filter Tech at a cost of $16,245 or 24% of the total capital investment.

The total capital cost of $66,362 was normalized to $2,212/gpm ($1.54/gpd) of design capacity using the
system's rated capacity of 30 gpm (or 43,200 gpd). The total capital cost also was converted to an
annualized cost of $6,264 gal/year using a capital recovery factor 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/week at the design
flowrate of 30 gpm to produce 15,768,000 gal/yr, the unit capital cost would be $0.40/1,000 gal. During
the demonstration study, the system produced 8,354 gal of water daily (Table 4-8) or 3,049,000 gal
annually, the unit capital cost increased to $2.05/1,000 gal.  These calculations did not include the
building construction cost.

4.6.2       O&M Cost. The O&M cost includes cost for media replacement and disposal, electricity,
and labor, as summarized in Table 4-15. Although neither the oxidizing nor the AM was replaced during
the performance evaluation study, the media replacement cost would represent the majority of the O&M
cost. It was estimated that the Birm®/Filox™ media would have a life expectancy of 10 years and that it
would cost $8,175 to replace 20 ft3 of media in two vessels (including the cost for media, labor, freight,
and media disposal). At the current water use rate (i.e., 3,049,000 gal for one year), the system would
treat 30,490,000 gal of water in a 10-yr period. Therefore, the Birm®/Filox™ media replacement cost
would be equivalent to $0.27/1,000 gal of water treated.

It also was estimated that it would cost $8,440 to change out 10 ft3 of Adsorbsia™ GTO™ media, including
the cost for media, labor, freight, and media disposal. This cost was used to estimate the media
replacement 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 4-26).

No cost was incurred for repairs because the system was under warranty. Electrical power consumption
was calculated based on the  difference between the average monthly cost from electric bills before and
after the building construction and system startup. The difference in cost was approximately $100/month
or $0.39/1,000 gal of water treated.  The routine, non-demonstration related labor activities consumed
approximately 30 min a day, six days a week.  Based on this time commitment and a labor rate of $30/hr,
the labor cost was $1.54/1,000 gal of water treated.
