Off-Site Contaminated Groundwater Fact Sheet
Sherwood Medical Industries Superfund Site
	DeLand, Florida	November 2002
ckground
The Sherwood Medical
Industries Superfund Site
is located approximately
three miles northeast of
DeLand, Florida and covers approximately
42 acres. The Site was listed on the National
Priorities List (NPL) in 1983 and underwent
numerous investigations through 1991.
Since 1959, the Site has been used for the
manufacture of medial supplies, primarily
hypodermic needles. Operations include
grinding, cleaning, hub
processing, and de-coring
of stainless steel and
aluminum parts used to
manufacture hypodermic
needles.
While the Sherwood Site was sold to Tyco
Healthcare Group in 1998, Wyeth retained
responsibility for the Superfund
environmental liability.
The Tyco Healthcare Kendall facility pumps
approximately 175,000 gallons/day from the
underlying Floridian Aquifer for industrial
needs such as cleaning, manufacturing, and
cooling/evaporation processes. Several
manufacturing steps result in wastewater that
is treated at an onsite industrial treatment
plant before being discharged to the City of
Deland sewer system.
Groundwater
Contamination
Environmental studies in the 1980s/early
1990s determined that groundwater at the Site
was contaminated with volatile organic
compounds (VOCs) from former process
wastes (e.g., tetrachloroethene (PCE),
trichloroethene(TCE)).
The 1980s/early 1990s work showed the
surficial or shallow aquifer (i.e., the aquifer
from the land surface down to about 55 feet
below land surface (bis)) to be contaminated
onsite and just to the east of Kepler Road.
The shallow aquifer is underlain by a four to
eight foot thick clay. Below the clay lens is a
layer of sand and shell to a depth of
approximately 100 feet. The Floridan Aquifer
begins at about 100 feet bis with the
occurrence of limestone. Sampling from the
1980s/early 1990s found that the onsite
Floridan Aquifer was also contaminated with
VOCs. However, Floridan monitoring wells
located to the west and east of the Site
indicated that the Floridan groundwater
contamination had not migrated offsite.
Groundwater
Cleanup/Remedy
On March 27, 1991, EPA selected an interim
remedy to prevent the migration of
contaminated groundwater off site. The

-------
remedy included the installation of a system
of onsite recovery wells in the surficial
aquifer, installation of an onsite air stripper to
treat recovered groundwater, and discharge
of treated groundwater into Lake Miller.
The Consent Decree between EPA and
Sherwood Medical was entered on
February 3, 1992, and the remediation system
was constructed and became operational in
the summer of 1992. Following completion
of the full site investigation, EPA selected a
final remedy on October 8, 1992, which
included the following elements: continued
operation of the surficial aquifer pump and
treat system; continued
operation of the Floridan
Aquifer production well and
associated treatment system;
remediation or disposal of
excavated soils (as necessary)
which exceed performance criteria;
implementation of a long-term groundwater
monitoring program (including residential
wells); and establishment of institutional
controls to limit use of and access to the Site.
An amendment to the Consent Decree to
address these additional requirements was
entered on September 23, 1993.
Analysis of Groundwater
Cleanup
EPA completed a Five-Year Review of the
cleanup in 1999. Five-Year Reviews are
conducted to ensure the remedy continues to
be protective. The Five-Year Review Report
concluded that the performance standards for
the remedy remain protective, but the review
documented deficiencies in operation &
maintenance (O&M) and identified remedial
measures to address the deficiencies.
As a result of the Five-Year Review process,
a revised O&M Plan has been developed and
submitted to EPA, and a work plan to collect
additional data needed for the next Five-Year
Review was developed and submitted to EPA.
The work plan included further groundwater
assessment both onsite (i.e., the Tyco
Healthcare Kendall Plant) and offsite (i.e.,
east and southeast of the Tyco Healthcare
Kendall Plant). The plan was approved by
EPA on December 10, 2001.
Status of the Current Off-Site
Groundwater Assessment
Although a report has not
yet been generated for the
offsite groundwater
assessment which began
in February 2002, some
of the main offsite assessment activities and
results include the following:
Surficial Aquifer
*	Over 150 groundwater samples at 75
locations have been collected from the
shallow aquifer via Geoprobe technology
and field analyzed for VOCs.
*	Three new shallow aquifer monitoring
wells were installed just to the east of
Kepler Road and an additional shallow
well installed south of the property.
VOCs have been detected in the shallow
aquifer and have been tracked to the edge
of Lake Cypress (see Figure 1).
Floridan Aquifer
*	Two new Floridan Aquifer monitoring
wells were installed just to the east of
Kepler Road to replace private residential
wells used as monitoring points. These
private wells were taken out of service
when water became available from the
City of Deland. There are now five offsite

-------
Floridan Aquifer monitoring wells just to
the east of Kepler Road.
VOCs have not been detected in the
Floridan Aquifer by the offsite
monitoring network during this study.
Groundwater impacts to the Floridan
Aquifer occur in a limited area beneath
the plant and are held on-site by the
pumping of the plant's industrial process
water supply well (see Figure 2).

Next Steps
* Complete the
remaining onsite assessment
work on the Floridan Aquifer.
This work is scheduled to
begin in December 2002.
* Once the December onsite assessment
work is completed, a report will be
generated explaining the onsite and
offsite assessment activities performed to
date. The report will also include
recommendations for any needed further
actions (e.g., additional assessment,
modification to the groundwater cleanup
system).
