EPA Proposes Plan for Next Phase of
Cleanup at the Sherwin-Williams/Hilliards Creek Superfund Site in Gibbsboro,
Lindenwold, and Voorhees, New Jersey
NEW
YORK (April
1, 2021) – The U.S. Environmental Protection Agency (EPA) is proposing a
cleanup plan to address waterbodies of the Sherwin-Williams/Hilliards Creek
Site in Gibbsboro, Lindenwold, and Voorhees, New Jersey. The proposed plan
calls for the dredging of contaminated sediment, along with excavation and
capping of floodplain soil at Silver Lake, Bridgewood Lake, Kirkwood Lake, and
Hilliards Creek.
“The
cleanup of these waterbodies has long been sought by these communities and we
are proud of this proposal,” said EPA
Acting Regional Administrator Walter Mugdan. “The proposed
cleanup addresses arsenic and lead contamination that poses serious risks to
people, fish and wildlife.”
There
are three Sherwin-Williams Superfund sites that are sources of contamination to
the waterbodies. The sites are located within the municipalities of Gibbsboro,
Voorhees, and Lindenwold, New Jersey. Contamination from past paint
manufacturing originates within the area of the Former Manufacturing Plant
(Sherwin-Williams/Hilliards Creek Superfund Site), the Route 561 Dump Site, and
the United States Avenue Burn Superfund Site. These source areas are being
cleaned up under separate actions. Contaminants from these three sites have
moved downstream throughout the lakes and creeks within Gibbsboro, Voorhees and
Lindenwold.
EPA’s
proposed plan calls for the dredging of 128,000 cubic yards of contaminated
sediment from Silver Lake, Bridgewood Lake, Kirkwood Lake, and Hilliards Creek.
This plan also includes the construction of a system to temporarily divert
streams during the cleanup.
In
addition, EPA proposes to remove approximately 42,000 cubic yards of the top
two feet of soil located with the floodplain areas and cap contaminated soil
below two feet. EPA’s proposed plan provides for treatment, transport and
disposal of excavated sediment and soil off-site at a permitted facility, and
implementation of institutional controls in the form of deed notices. This plan
will be protective of human health and the environment while preserving
high-value wetland areas.
Throughout
the proposed cleanup, EPA will monitor and further study the cleanup progress
to ensure the effectiveness of the remedy and conduct a review of the cleanup
every 5 years to ensure its effectiveness. Under the proposed plan, the
estimated cost of this cleanup is approximately $90 million.
A
30-day public comment period for the proposed plan will occur from April 1,
2021 to May 3, 2021. EPA will host a Virtual Public Meeting on April 12, 2021
at 7:00 p.m. To register for the public meeting, visit https://epa-sherwin-williams-ou4.eventbrite.com.

EPA Issues Administrative Order
Requiring City to Construct Sewage Retention Tanks for Gowanus Canal Superfund
Site Cleanup
NEW
YORK
(March 30, 2021) The U.S. Environmental Protection Agency (EPA) ordered the
City of New York (city) to construct and operate two Combined Sewer Overflow
(CSO) retention tanks to control contaminated solids discharges at the Gowanus
Canal Superfund site in Brooklyn, New York, which is a key component of the
Gowanus Canal cleanup. The EPA’s order follows previous orders that EPA issued
in 2014 and 2016 to require the city to find a location for and design the two
tanks. Controls to reduce CSO discharges and prevent other land-based sources
of pollution, such as street runoff, from compromising the cleanup are a
critical part of the site’s cleanup plan.
“This
order will ensure that EPA’s cleanup efforts will not be undermined by
uncontrolled combined sewer overflow discharges that have contributed to the
chemical contamination of this waterway and impacted this community for the past
century and a half,” said
EPA Acting Regional Administrator Walter Mugdan. “To ensure the
integrity of the dredging work, the retention tanks will control New York
City’s sewer outfalls over the long-term.”
The
administrative order, issued on March 29, 2021, requires the city to construct
one 8-million-gallon tank, located at the head of the canal, and one
4-million-gallon tank, located at a New York City Department of Sanitation Salt
Lot near the middle of the canal.
The
order also requires the city to, among other things:
Ensure
that developers comply with municipal stormwater regulations within the
Gowanus area to prevent additional sewer volume from impairing the
effectiveness of the CSO tanks;
Provide
treatment for separated stormwater discharges;
Perform
monitoring of sewer solids discharges to ensure protection of the dredging
remedy;
Perform
associated maintenance dredging, if determined by EPA to be necessary;
Construct
a bulkhead on City-owned property to prepare for the second phase of
dredging work; and
Adhere
to an overall schedule for remaining tank design work and construction.
The
2013 cleanup plan for the Gowanus Canal Superfund site includes dredging to
remove contaminated sediment from the bottom of the canal, which has
accumulated because of industrial activity and CSO discharges. More than a
dozen contaminants, including polycyclic aromatic hydrocarbons, polychlorinated
biphenyls, and heavy metals, including mercury, lead, and copper, are present
at high levels in the Gowanus Canal sediments. Dredged sediment that contains
high levels of liquid tar will be thermally treated at an off-site facility and
disposed. The less contaminated dredged sediment will be processed at an
off-site facility to transform it into a beneficial use product, such as
landfill cover. Certain areas of the native sediment, below the original canal
bottom, that contain mobile liquid tar and are too deep to excavate, will be
mixed with cement and solidified to prevent the migration of the tar into the
water of the canal. Following dredging and solidification of areas of the
native sediment, construction of a multilayer cap in dredged areas will isolate
and prevent migration of any dissolved chemicals remaining in the deep native
sediments.
Cleanup work to resume next month at
Grasse River Superfund Site in Massena, New York
ALBANY,
NY (March
30, 2021) – The U.S. Environmental Protection Agency (EPA) announced today that
in-river work will resume next month to address sediment contaminated with
polychlorinated biphenyls (PCBs) at the Grasse River Superfund Site (aka Alcoa
Aggregation) in Massena, New York.
“It’s
exciting to see the tremendous progress that has been made as we near the
finish line for this critically important project,” said Walter Mugdan, Acting
Regional Administrator. “EPA, the New York State Department of
Environmental Conservation, and the Saint Regis Mohawk Tribe continue to work
together on the oversight of the various components of the project.”
In
2013, EPA selected a cleanup plan for the site that called for dredging and
capping of PCB‐contaminated sediment in a 7.2‐mile stretch of river. The 2021
work will primarily include placement of a 12-inch sand, gravel and/or stone
cap in the lower five miles of the main river channel from the Route 131 Bridge
to the mouth of the Grasse River, covering over 200 acres; sand backfilling in
areas dredged in 2020 near Snug Harbor; and habitat reconstruction throughout
the site. The major elements of the in-river work are expected to be completed
by the end of 2021. COVID-19 protocols will continue to be followed and
safeguards will be maintained for the protection of site workers and the
community.
To
support this year’s work, an extended underwater pipeline will be used to
transport some clean capping material from two staging areas to river
locations. This operation will occur 24 hours a day, six days a week. The
pipeline will be submerged along the river shoreline, with some floating
sections near the cap operations. The pipeline will be marked with orange and
white buoys. Designated crossing areas will be marked with green and red buoys
in the channel. The remainder of the capping material will be transported by
barges pushed by tugboats and placed mechanically on the river bottom using
excavator-type buckets. On-river warning signs will be posted to alert oncoming
boating traffic.
Information
on boater safety can be found on the Arconic project website: www.thegrasseriver.com.
Additional recreation advice is available from the New York State Department of
Health: “Recreation
Advice for Lower Grasse River During Dredging and Capping.” Recreational
boaters are asked to take caution, reduce speed and adhere to traffic patterns
in the project area.
A
limited amount of dredging will be conducted in the navigational channel in
2021 just downstream of Snug Harbor. Snug Harbor is a small embayment (an
embayment is a part of a body of water that extends beyond the general
shoreline) on the north shore of the Grasse River, located about a third of a
mile upstream from where it joins the St. Lawrence River. In 2020, EPA modified
its original cleanup plan to include removal of an additional 90,000 cubic
yards of sediment, instead of capping, from an area of the river near Snug
Harbor. This additional removal was needed to accommodate a new, larger tugboat
purchased by the St. Lawrence Seaway Development Corporation, which operates
its tugboat out of Snug Harbor. Dredging was substantially completed at Snug
Harbor in 2020. Approximately 110,000 cubic yards of sediment was removed from
20 acres of the river. Clean backfill material will be placed in this area in
2021.
Two
shoreline support areas will be used in 2021 to store and manage capping material;
one is the staging area located near the intersection of County Route 42 and
Route 131 in Massena and the other is a newly constructed staging area on
Haverstock Road. Clean capping material will be brought to these areas by truck
and transported by barge or pipeline to the cap placement equipment on the
river. As with previous phases of work, a traffic management plan will be
in place to address the increased truck traffic at and near the staging areas.
The Alcoa East Plant dock will also be used to support the project. While
efforts will continue to be made to minimize traffic impacts, residents should
exercise caution when driving in these areas.
Health
and safety plans have also been developed to protect workers and area
communities while work is underway. The air and river water will be monitored
during the work, and the results will be available on Arconic’s project
website: www.thegrasseriver.com.
Noise and lighting in the work zones will also be monitored. Efforts will
be made to mitigate noise generated from the construction activities. The
submerged pipeline is expected to help reduce noise levels associated with
capping operations during nighttime hours. Mechanical capping will be limited
to daytime hours.

Advocacy group says some substances top
recommended health limits; most samples met standards set by the U.S.
Environmental Protection Agency
The latest tally of contaminants was 26 more than in the last report by the Environmental Working Group.
Drinking water supplied by New Jersey utilities between 2012 and 2017
contained 107 contaminants — some of which were at levels that
advocates say are harmful to human health, according to a survey published on Wednesday.
The advocacy organization Environmental Working Group used data from the state Department of Environmental Protection
on drinking water quality at New Jersey’s 579 utilities, as part of its
national U.S. Tap Water Database, a biennial report. The latest tally
of contaminants was 26 more than in the last report, covering the years
2010-2015, which was released two years ago.
In New Jersey, the report found some samples from larger utilities
contained contaminants at levels that exceeded health limits as
recommended by other states or by the nonprofit itself, although nearly
all samples met standards set by the U.S. Environmental Protection
Agency.
Although the samples were taken as long ago as 2012, the
contamination levels found are probably the same now unless a supply has
been treated, said Chris Campbell, vice president for information
technology at EWG.
“It is likely, barring installation of some form of treatment, that
the levels now are similar to 2015-2017, which is the timeframe used on
most contaminants,” he said.
The ‘Erin Brokovich’ chemical
The most common contaminant in New Jersey was hexavalent chromium,
the so-called “Erin Brockovich Chemical” — named after the well-known
public-health campaigner in California — that is used in the manufacture
of dyes, paints, inks and plastics, and can cause lung cancer if
regularly inhaled, according to federal health experts. The chemical was
found at above EWG-recommended health limits in the water of 202 New
Jersey utilities serving some 7.5 million people, the report said.
The second most common contaminant was bromodichloromethane, a
chemical formed when chlorine is used to disinfect drinking water, and
which has been linked in animal studies to cancer of the liver, kidneys
and intestines, according to federal scientists. In New Jersey, there
were 193 utilities serving some 5.1 million people where the chemical
was found at above EWG’s recommended health limits, the report said.
EWG bases many of its health recommendations on standards set by
California, or its own research. In New Jersey, there were 10
contaminants that exceeded the EWG-recommended health levels but only
two that exceeded federal legal limits, the report said.
Utilities where multiple contaminants were found included Atlantic City, which
had 10 chemicals that exceeded EWG’s health standards — the same number
as in the 2017 survey. Still, the city’s water met all federal health
requirements between January and March this year, the report said.
The Atlantic City contaminants included PFOS (perfluorooctane
sulfate), one of the potentially carcinogenic PFAS family of per- and
polyfluoroalkyl chemicals, at 33 times EWG’s recommended limit, and the
related chemical PFOA (perfluorooctanoic acid) at 12 times the limit.
The PFOA level was just within a new health limit that’s being adopted
by the Department of Environmental Protection, while the PFOS level
exceeded the state standard. EWG said it had no information on the
source of contamination at Atlantic City.
Meeting federal standards
Atlantic City’s water also contained arsenic at 31 times EWG’s health
guideline, and chloroform that was 40 times higher than the recommended
EWG health limit. Arsenic is the only one of the 10 contaminants in the
city’s water that’s subject to a federal legal limit of 10 micrograms
per liter.
Still, Atlantic City, whose water system serves about 152,000
customers, complied with federal standards on lead, the survey found.
Only 3.2% of the households sampled in Atlantic City exceeded the EPA’s
lead health limit of 15 parts per billion (ppb) during the latest
testing in 2017.
Among other utilities, New Jersey American Water’s western region system, serving some 264,000 people, also exceeded EWG’s health guidelines for 10 contaminants including hexavalent chromium and chloroform, neither of which have a legal limit.
New Jersey American Water said the substances identified by EWG in
its water are mostly by-products of water disinfectants, which meet all
regulatory requirements, and were previously reported to the DEP. Others
are chemicals in source water at levels well below “recognized” state
or federal drinking water standards.
“While we do not specifically treat for these unregulated compounds,
their presence is affected by the overall treatment process,” the
company said in a statement. “New Jersey American Water treats and
delivers water that meets or surpasses EPA and New Jersey drinking water
standards.”
Using California’s public health goals
The company’s president, Cheryl Norton, said the health limits
advocated by EWG often use California’s public health goals that are a
lot stricter than implemented state standards that take into account
other factors like detectability and the cost of treatment. For example,
she said California’s enforceable limit for arsenic is 2,500 times
higher than its public health goal and matches the federal level.
At Woodbridge-based Middlesex Water, serving about 233,000 customers, hexavalent chromium and PFOA were both found at above recommended levels.
Middlesex’s chief executive, Dennis Doll, said the report was in line
with the company’s own findings. “We don’t agree with the EWG’s
methodology but the results they are reporting are not an unreasonable
representation of our numbers,” he wrote in an email.
He noted that EWG’s health limits are recommendations, not
regulations, and so the reported levels do not violate any legal limit.
He called EWG’s proposed limit of 1 part per trillion (ppt) for PFOA
“outrageously low and not based on sound science.” The PFOA level in the
EWG report is based on only one Middlesex well, and so represents a
very small part of the company’s overall system, he said.
While the PFOA level in the Middlesex system topped EWG’s
recommendation, it was within the level that is being adopted by the
DEP.
Unsound science driving ‘race to zero’?
The Water Research Foundation, a national group that Doll chairs,
believes pressure on utilities and regulators from EWG and other
advocates is resulting in “a race to zero” that he said is not being
driven by sound science or EPA policy.
Still, EWG said the data shows that the EPA should set stricter
standards on drinking water contaminants. “Legal does not necessarily
equal safe,” the group said. “Getting a passing grade from the federal
government does not mean the water meets the latest health guidelines.”
For its part, the EPA said it has set enforceable maximum contaminant
limits (MCLs) for some chemicals including arsenic and chloroform, and
has issued a number of regulations since the 1995 amendments to the Safe
Drinking Water Act to reduce the risks of pathogens in ground water and
surface water, and from disinfection by-products.
On PFAS, the agency reiterated that it will decide by the end of this
year whether to begin regulating PFOA and PFOS, and is evaluating other
PFAS chemicals for possible regulation.
Andrea Drinkard, a spokeswoman for EPA, said the agency distinguishes
between the enforcement levels and “Maximum Contaminant Limit Goals”
(MCLGs), as set by the Safe Drinking Water Act. For example, the MCLG
for arsenic is zero because there is no level of arsenic in water that
is without risk, but the EPA has set 10 micrograms per liter as the
enforcement level “in accordance with SDWA requirements that EPA
consider the feasibility, costs, and benefits when establishing
regulations,” she said.
Different standards
Arsenic is one of 14 contaminants for which New Jersey has stricter limits than the EPA, according to the DEP’s Annual Compliance Report for 2018,
which describes the different standards that water utilities are
required to meet. That report names 49 water systems that exceeded
maximum contaminant limits for different chemicals during the year, and
another 29 that topped the EPA’s “action levels” on lead and copper.
The survey comes as New Jersey lawmakers and advocates step up their
efforts to renew aging water pipes and sewers that leak drinking water
and spill raw sewage during rainstorms. Municipal and investor-owned
water utilities are also working to ensure that public water supplies
are free of contaminants such as the lead that comes from antiquated
pipes, and the PFAS chemicals that persist in many water systems long
after their industrial uses have ended.
On Oct. 10, Gov. Phil Murphy set a target of replacing the state’s estimated 350,000 lead service lines
— pipes that connect individual homes with water transmission lines —
within 10 years. He proposed a $500 million bond to help utilities
comply with the target, which is expected to cost some $2 billion in
total.
Murphy’s initiative came on the same day as a major report on lead
from Jersey Water Works, a consortium dedicated to renewing the state’s
antiquated water infrastructure, and followed recent alarm over lead
contamination in Newark where authorities are already replacing lead
lines and helping residents install in-home filters.
