Toxaphene Analysis Flawed
Next Steps to Correct the Problem
The
EPA Inspector General (IG) released his report on the Hercules 009 Landfill
Superfund Site on September 26th, and recommended appropriate testing for
toxaphene be conducted. The report was prepared as a result of numerous
inconsistencies with toxaphene containment identified by the Glynn
Environmental Coalition (GEC). “When modifications were made to the EPA's
toxaphene analytical method in 1993, we suspected toxaphene present may not
be reported,” said technical advisor Dr. Kevin Pegg. “Repeatedly, the
Toxaphene Task Force method failed to find toxaphene when it was present in
large quantities. Since the containment was based upon flawed data, there
is no assurance that all contaminated soils in the neighborhood and
schoolyard next to the Superfund Site were removed.”
The IG noted that the modified analytical method used was not effective
for detecting degraded toxaphene in soil, water, and fish. The severity of
the problem was demonstrated when 56 fish samples were analyzed and were
reported as no toxaphene present. When more accurate analysis was done,
toxaphene was found at over 52 times the EPA’s "do not eat" level for
toxaphene.
For the past 12 years, toxaphene has been analyzed in Glynn County by a
flawed method. This includes sampling of neighborhoods, schools, and six
toxic waste sites. Our goal is to have all areas sampled by the flawed
method re-tested. At the top of our priority list is Altama Elementary
School that abuts the Hercules 009 Landfill Superfund Site. Like the IG
said, the previous method was inadequate, and we should not take chances
with our children’s health and safety.
The GEC has met with Glynn County Schools Superintendent Michael Bull to
form a partnership to move sampling and analysis at Altama Elementary
forward with all due speed. The GEC has worked well with our school
administrators in the past, as in the testing at Goodyear Elementary School
that led to removal of toxic soil from the schoolyard. We look forward to
building off our successes in keeping our schools safe for our kids.
The Hercules 009 Landfill Superfund Site containment plan has been
changed significantly since the legally binding agreement was signed by
Hercules and the EPA in 1992. There were five major changes that
significantly changed the protectiveness of the remedy. Instead of treating
all the toxaphene sludge, only sludge above the water table was solidified
with cement, leaving up to a 10-foot thick layer of sludge untreated. This
reduction in sludge treatment significantly reduced the amount of
contaminated soil that was treated. Initially, the EPA promised to treat
the sludge in place but did excavate what was treated, which caused exposure
to those that live and work around the Superfund site. Once the
containment was complete, there were confirmation samples to be taken to
assure that all sludge was treated, which has not been done to date. In
light of the changes made which assure that all sludge was not treated, this
is not a surprise but still needs to be done to assess containment work
completed to date. Once the containment work was complete, a clay cap
followed by soil was to be placed over the Superfund site. Instead,
contaminated soil was spread over the top and mixed with a little cement,
followed by clean soil to grow a grass cover. With so many changes made to
the containment plan, confirmation sampling is needed in the soils
underlying the Superfund site, in addition to the groundwater sampling
recommended by the IG. Both the groundwater and soil confirmation samples
should be analyzed by the method recommended by the IG.
