Layer Aeration
Installation of a Layer Aeration System in a
water supply reservoir in New Jersey.
Layer Aeration, which has been awarded
a U. S. Patent, has been used in lakes
and supply reservoirs in New England
and around the country The technology
was developed to improve water and
habitat quality in lakes and reservoirs for
fishery restoration, water supply source
improvement, and lake restoration. Layer
Aeration addresses the causes and
consequences of eutrophication.
Unlike other aeration methods which
are dependent on "mechanical" oxygen
input, Layer Aeration actually uses
biological oxygen sources. It creates and
aerates discrete layers at selected depths,
bounded by functional thermoclines
above and below. The method "bal-
ances" photosynthetic oxygen production
and respiratory oxygen demand. It
utilizes natural biological processes to
decrease dependence on large compres-
sor systems (saving energy and cost).
Recent technology advances in the Layer
Aeration process have included a "down
bubble contact reactor" function which
enhances gas-solute phase transfer and
improves efficiency further, and sub-
merged systems.
Layer Aeration is useful for cost-
effective water supply quality improve-
ment (at intake depths) and for cold
water habitat restoration. The method
is best for deep eutrophic lakes that
thermally stratify.

BioFence
Environmental Resource Corps (ERG) is
the first company to be a "back-to-back"
winner of EPA's Environmental Technol-
ogy Innovator Awards —last year for the
Rowland Swale and this year for the
BioFence.™ The BioFence™ was also
recognized in 1998 by the International
Erosion Control Association and
received their Award for Environmental
Excellence. "These awards have brought
a phenomenal response," writes Mark
Rowland, Chief Biologist at ERC. "We
have logged 5,673 requests for product
literature, and other information regard-
ing one or the other product."
BioFence,™ an alternative to a hay
bale and plastic fence, is for use in areas
that need to be protected from silt,
erosion materials, and sedimentation.
BioFence™protecting wetlands from silt and
erosion during an interstate installation
project on a major U.S. highway.
The advantages of BioFence™ are
that it:
• provides greater silt removal than the
hay bale/plastic fence;
• uses materials that are totally biode-
gradable and non-toxic;
• unlike most hay bales, is not contami-
nated with plant materials that can
invade wetlands; and,
• is made in the U.S.—offering price
advantages over imported products.
According to ERC, BioFence™ has
several advantages in silt removal. The
product is 10 to 20% better than a hay
bale/plastic fence combination in
catching silt. BioFence™ is composed of
aspen wood fibers. The irregular edges
of the wood fibers catch small silt
particles better than the round edges of a
piece of straw or the smooth plastic
fibers of a silt fence.
BioFence™'s backing material is
made of burlap stiffened with corn
starch. Unlike plastic silt fences, the
burlap will swell during a storm event
tightening the weave and trapping silt on
its own. It dries out after a storm
allowing the opening to re-establish itself
to permit water to pass through.
Most traditional black plastic fences
are attached to stakes by stapling. Staples
are thin, flimsy attachments for the

weight fill can place against a fence.
BioFence™ stakes are made by sewing
looped seams to inserted wooden stakes.
The stakes are installed as part of the
assembly so that the unit is ready-to-
install. BioFence™'s 4' stakes place the
stake 18" into the ground rather than the
usual 8".
BioFence™ has five variations:
(1) BioFence™ Plus —wild flowers
embedded in the fence; (2) BioFence™
with EcoGuard— a natural oil absorp-
tion boom in the fence; (3) BioFence™
with Skeeter Guard—fence impregnated
with Bti mosquito larvicide;
(4) BioFence™ Skeeter Repel—fence
coated with pyrathenum to repel adult
mosquitoes; (5) BioFence™ Superior—
heavyweight/high velocity grade for
steep runoff situations.

KADY Bio-Lysis System
KADY International's innovative technol-
ogy, the KADY Bio-Lysis System™
(BLS), reduces the volume and weight
of disposable sludge produced by
wastewater treatment plants. The
KADY BLS™ is a technique that shears
and breaks apart solid particles and
ruptures microbial cells in biological
wastewater sludge. By breaking the cell
wall, the cytoplasm contents are available
as a food source for living organisms in
the wastewater treatment (WWT) plant.
The resultant product of solubilized
cytoplasm, fragmented particles and free
water can be returned to the aeration
system, rather than be removed as solid
waste. The reduction in biosolids
(sludge) through the KADY BLS™
results in smaller quantities of sludge to
be pumped, thickened, dewatered and
disposed. In addition, the destruction of
particulate matter and cell structure
results in wastewater biosolids that are
more easily dewatered using conven-
tional dewatering equipment.
According to Kent Peterson of Kady
International, this KADY technology
offers a cost-effective solution for
reducing one of the largest operating
costs in the WWT plant. The KADY
BLS™ is a small, compact unit that is
easily installed in an exiting process
stream. It is energy efficient and
requires little operating intervention.
The reduction in biosolids results in
lesser quantities which must be handled
by further processing. Thus, there are
less biosolids to be dewatered, less to be
stored, less to be transported to disposal,
and less to be disposed of in landfills, by
land spreading, or by incinerating.
When installed in an activated sludge
treatment plant, the KADY BLS™
permits the plant to reduce its operating
costs by consuming a substantial portion
of the secondary biosolids generated.
The KADY BLS™ was demonstrated
at a 15 million gallons per day activated
treatment plant in Portland, Maine in
1997. The 12-month study showed a
50% reduction in biosolids. An addi-
tional pilot study was completed in 1998
at the Detroit Water and Sewage
Department which showed a 33%
reduction in biosolids. In addition to
sludge reduction, KADY BLS™ was
reported to improve BOD, COD, TSS,
and PO4 in the pilot effluent.

ETHEC
Concrete product samples from contaminated Salem, MA Harbor sediment.
Dr. Alex Gurfinkel has developed and
patented ETHEC (Electro-THErmo-
Chemical), a technology which inte-
grates electrical, thermal, and chemical
techniques for cleaning up and recycling
hazardous wastes and other contami-
nated materials. The ETHEC process
and systems are designed to provide a
one-step cleanup/recycling operation.
The ETHEC process extracts and
separates water and vaporizable organics
from wastewater or sludge and produces
pure water and usable organic com-
plexes. Contaminated sediments, soils or
other residues can be cleaned up by
extracting the organics or through
ETHEC's manufacturing of beneficial
use products. The ETHEC technology
simultaneously treats the contaminated
material and the contaminants without
using chemicals in the process. Any
heavy metals left in the processed
material are stabilized by a thermo-
chemical reaction during the final step of
recycling the treated waste into either
fill, aggregate, or building materials.
ETHEC systems are designed as
mobile, fixed, or in-line installations.
The mobile and fixed systems can be
used for on-site and off-site remediation,
respectively, and the in-line systems, for
both remediation and pollution preven-
tion. These in-line systems can be
adjusted for optimal operation, while the
mobile and fixed systems can be adjusted
to produce the selected beneficial
products. The system is closed-loop so
it does not emit any contamination into
the atmosphere.
This technology can be used in
dredging projects, hazardous and
industrial waste cleanup projects, and in
treating municipal wastewater.
ETHEC's target waste streams include
soil, sediment, wastewater, sludge,
industrial waste, and chemical and
biological contamination.

CoMag Process
Micormag Corporation was formed in
1997 to address serious eutrophication
of a ten-mile stretch of ponds and
streams comprising the Hop Brook
recreation and wildlife resource area in
Marlborough, Massachusetts. In
response, Micromag Corporation
developed the CoMag Process poten-
tially applicable to a broad range of
municipal and industrial wastewater
treatment facilities. The process is
particularly effective for the removal of
phosphorus and can remove fecal
coliform and other pathogens without
the use of chlorine.
The CoMag Process incorporates
a dynamic, magneto-chemical
pre-treatment process which enhances
the precipitation of dissolved contami-
nants. The process also adds a fine
magnetite powder (magnetic seed) and a
chemical flocculant. The flocculant
binds all of the fine particulates in the
fluid stream, including the precipitated
phosphorous, to magnetite powder,
which can then be filtered at very high
rates using High Gradient Magnetic
Separation (HGMS) technology. A
means for recycling the magnetic seed is
incorporated into the process so that it is
not lost in the final sludge.
In conjunction with the Mass. DEP,
the EPA, and the City of Marlborough,
the technology has been demonstrated in
a full process, continuous duty, pilot
plant at the MEWWTP Within a year
the new process demonstrated its ability
to reduce phosphorous to 0.01 mg/1.
The plant study for the Marlborough
application estimated its cost at less than
half that of existing technology.

s/feLAB UVF Analytical Test Kit
After one and a half years of research
and development MteLAB8 was incorpo-
rated in Massachusetts in the spring of
1998. The corporation consists of
several business partners and employees
and sells its products throughout the
U.S. The «teLAB8UVF Analytical Test
Kit was developed and patented by Steve
Greason, an Environmental Science
graduate from University of New
Hampshire, with 10 years experience in
the environmental industry
The UVF Analytical Test Kits are
designed to measure a variety of
petroleum hydrocarbons, including total
petroleum hydrocarbon (TPH); volatile
petroleum hydrocarbon (VPH); extract-
able petroleum hydrocarbon (EPH)
aromatic fractions; polycyclic aromatic
hydrocarbon (PAH); benzene, toluene,
ethyl benzene, and xylene (BTEX); and
polychlorinated biphenyls (PCBs).
According to wteLAB8, the kits are fast,
accurate and cost-effective. Soil or
water samples are extracted in solvent
and then analyzed on a portable ultravio-
let fluorometer (UVF), which is cali-
brated using the same type of certified
standards conventional laboratories use
for gas chromatograph/mass spectrometer
(GC/MS) analysis.
The UVF Analytical Test Kits provide
on-site data useful to many regulatory
agencies, utilities, consultants, contrac-
tors and project managers. Applications
include commercial and residential soil
excavation projects, underground storage
tank (UST) spills, site assessments,
geoprobe investigations, non aqueous
phase liquid (NAPL) plume studies,
emergency response situations, mobile
or field laboratories and dilution screening
for commercial labs prior to
GC/MS analysis.
"The siteLAW3 test kits are the only
available screening tools capable of
measuring VPH and EPH, which will
directly correlate to off-site laboratory
GC results," says Greason, "As a result,
far fewer samples need to be sent off-site
for confirmatory analysis. This, in
combination with its speed and low cost
per sample, can assist customers better
and much more quickly in delineating
the extent of contamination and reduce
the cost of cleaning up a site, not only in
terms of savings on analytical costs, but
also savings on disposal, treatment, site
work time, and labor."

StormTreat ™ System
Stormwater pollution is a leading cause
of non-attainment of water quality
standards throughout the New England
region. The majority of closed
shellfishing areas receive direct and
untreated Stormwater discharges.
The StormTreat™ System is designed
to treat Stormwater by capturing the first
flush of Stormwater runoff, which
contains 90% of pollutants. The system
provides high levels of treatment for a
broad range of pollutants. It also saves
space by reducing the need for detention
basins. An optional infiltration feature
provides for the treatment of larger
quantities of Stormwater (beyond the
first flush).
The StormTreat™ System is con-
structed of recycled polyethylene which
connects directly to existing drainage
structures. The system consists of a
series of six sedimentation chambers and
a constructed wetland which are con-
tained within a modular 9.5-foot diam-
eter and 4-foot deep tank.
Stormwater is piped through a
preliminary detention structure (open
detention basin, underground tank and
piping), which provides pre-treatment
and storage of the first flush volume, and
then into the StormTreat™ System The
water then enters the sedimentation
chambers where larger-diameter solids
are removed. The internal sedimenta-
tion chambers contain a series of
skimmers which selectively decant the
upper portions of the Stormwater in the
sedimentation basins, leaving behind the
more turbid lower waters. The skim-
mers significantly increase the separation
of solids compared with conventional
settling/detention basins. An inverted
elbow trap serves to collect floatables
such as oils within the inner tank.
After moving through the internal
chambers, the partially treated
Stormwater passes into the surrounding
constructed wetland through a series
of slotted PVC pipes. Unlike most
wetlands constructed for Stormwater
treatment, the StormTreat™ System
conveys Stormwater into the subsurface
of the wetland and through the root
zone, where greater pollutant attenuation
occurs. The Stormwater is then dis-
charged through the outlet valve, which
provides a five-day holding
time within the system. The valve
can be closed to contain a hazardous
waste spill.
The StormTreat™ System is the first
Stormwater treatment technology to be
officially verified by the Massachusetts
Schematic of the StormTreat System. The system
incorporates sediment chambers, decanting
skimmers and a constructed wetland.

Executive Office of Environmental
Affairs states that "the StormTreat
System can provide removal rates of at
least 80% for TSS when sized appropri-
ately In fact, in situations where the
climate, land use intensity and soil
conditions are similar to those found in
your Kingston demonstration site, your

Strategic Diagnostic Inc. Immunoassay Test Systems
Strategic Diagnostic Inc. (SDI) was
formed with the 1996 mergers of
Strategic Diagnostics, EnSys, Millipore's
EnviroGard, and Ohmicron Environ-
mental Diagnostic. The company is
headquartered in
Delaware and has a regional office in
Massachusetts. SDI provides the
environmental marketplace with immu-
noassay testing products.
Immunoassay analysis has been used
for more than 40 years in the medical
profession as a tool in clinical diagnos-
tics, with over a billion clinical tests
performed annually in the U. S. Immu-
noassay testing techniques are now
being applied to environmental analysis,
where immunoassay based test kits
provide environmental professionals with
a fast, simple low-cost method for
performing on-site analyses of many
regulated contaminants in water, soil,
and other environmental matrices.
Immunoassay based test kits for the
analysis of environmental contaminants
are predominantly of the competitive
enzyme-linked immunosorbent assay
(ELIZA) type.
In competitive ELIZAs, the sample
to be tested is combined with an enzyme
labeled analog of the analyte and the
analyte specific antibody. Both the
unlabeled (sample) analyte and the
enzyme labeled anaylyte analog then
compete for a limited number of
antibody sites and bind to antibodies in
direct proportion to their relative
concentration in the reaction mixture.
Field application of SDI immnoassay test kits.
After an incubation period, the antibody
with the labeled and unlabeled analyte
bound to it are separated from the
unbound substances. Color producing
reagents are then added to the antibody-
contaminant complex and allowed to
develop color during an incubation step.
Since the labeled antigen analog was in
competition for the antibody sites with
the target analyte contained in the
sample, less color indicates a higher
concentration of analyte.
Environmental immunoassay test
kits have been designed to be specific to
individual compounds such as individual
pesticides, or to be sensitive to com-
pound groups such as PAHs, PCBs or
petroleum hydrocarbons. When com-
bined with simple field sample prepara-
tion techniques, immunoassay technol-
ogy may be used to analyze many
different types of environmental matri-
ces, including soil, surfaces (wipes),
sediments, sludge, compost, concrete
and others. There are several different
types or "formats" for environmental
immunoassay, each having different
features and application characteristics.
SDI formats of immunoassay field test
kits include latex particles (D TECH),
coated tube (EnSys and EnviroGard), and
magnetic particle (RaPID Assay) types.
SDFs immunoassay test kits can provide
three types of analytical results: qualita-
tive, semi-quantitative, or quantitative
data results.

NEWMOA Technology Review Committee
Advisory Opinion on Immunoassay Field Analysis
Several groups in New England
recognized the need for a regional effort
to overcome regulatory and institutional
barriers to the acceptance of innovative
technologies, which have the potential to
cleanup and protect the environment and
public's health in a more cost-effective
and efficient manner. As a result, in
March 1998, the six New England
States, EPA Region I - New England,
the Northeast Waste Management
Officials' Association (NEWMOA) and
the New England Governors' Confer-
ence signed a Memorandum of Agree-
ment (MOA) to promote interstate
regulatory cooperation for waste site
assessment and cleanup technologies.
NEWMOA subsequently established
a Technologies Review Committee
(TRC) to address the lack of an inter-
state forum in the Northeast to actively
review technologies and communicate
both private and public sector use of
innovative technologies. The TRC is
made up of one or more staff members
from each of the New England states
and New York who coordinate state
review, issue advisory opinions and
disseminate information on the use of
innovative technologies.
On May 24, 1999, the TRC issued
an advisory opinion on Immunoassay
Field Analysis.
As an overview, the Advisory Opinion
states that the primary advantage of
immunoassay analysis is that analytical
results can be generated in real-time
allowing decision-making in the field
regarding the need for additional
sampling or further remediation (pro-
vided that proper data validation proce-
dures are followed). It strongly urges
potential users of immunoassay to consult
U.S. EPA Region I's Immunoassay
Guidelines for Planning Environmental
Projects (October 1996) and with kit
vendors prior to planning the field effort.
The Advisory Opinion also includes ten
(10) recommendations for improving or
insuring product performance.
