The 43-acre Sherwood Medical Industries site is located approximately three miles northeast of downtown Deland, Florida. Sherwood Medical Industries has used the property since 1959 for the manufacture of medical supplies, primarily hypodermic needles and syringes. Industrial operations currently include grinding, hub processing, and cleaning of stainless steel and aluminum parts used to manufacture hypodermic syringes. Sherwood also molds plastic syringes and conducts in-house laboratory work.
Liquid wastes from facility operations contained tetrachloroethene (PCE) and trichloroethene (TCE), and were discharged to septic tanks on site. Between 1971 and 1980, the facility disposed of approximately two tons of chromium-bearing liquid and sludge waste into two unlined percolation ponds on site.
The unlined percolation ponds were built in the shallow aquifer overlying the Floridan Aquifer, which supplies water for numerous private and public wells near the site, including the city of Deland's water supply well.
Ground water is contaminated with volatile organic compounds (VOCs) from former process wastes. Ground water contamination in the surficial aquifer has moved off site, but the surficial aquifer is not used for drinking water in the affected area. Contamination in the Floridan aquifer is limited to the site. Soils on the facility are contaminated with heavy metals.
Site Cleanup Plan
The cleanup plan for the Sherwood Medical Industries site covered three operable units (OUs): OU-1 (final remedy), OU-2 (soil and ground water), and OU-3 (Lake Miller sediments).An Interim Record of Decision (IROD) for OU-2 was issued in 1991. Major cleanup elements included:
- Installation of a system of recovery wells in the surficial aquifer on site.
- Installation of an on-site air stripper to treat recovered ground water.
- Discharge of treated ground water into an on-site lake.
The ROD for OU-2 was issued in 1992. Major cleanup elements included:
- Ground water pump-and-treat system for remediation of the surficial aquifer.
- Discharge of treated effluent to Lake Miller, a 12-acre lake located partially on the Sherwood Medical Industries site.
- Ground water monitoring program encompassing the surficial, Upper and Lower Floridan aquifers.
- Residential well monitoring to ensure that no contamination exists in wells immediately to the east and west of the site.
- Requirement for continued operation of the Floridan Aquifer Water Supply well and the associated treatment system to ensure capture and treatment of any migrated contamination.
- Requirement that soil excavated following building or parking lot removal meet Toxic Characteristic Leaching Procedure (TCLP) criteria or contain less than 520 mg/kg chromium. Soils exceeding these standards would be required to be remediated or disposed of in an appropriate waste facility.
- Land use restrictions allowing only industrial use of the site in the future.
The ROD for OU-3 was issued in 1997. EPA determined that no further action was necessary to address sediment contamination in Lake Miller. However, the site Operation and Maintenance Plan was revised to incorporate the following additional monitoring requirements to ensure that no unacceptable exposures to risks posed by conditions at the site occur in the future:
- Semi-annual sampling of Lake Miller sediment and surface water.
- Limited fish tissue sampling in Lake Miller and adjoining lakes.
Site cleanup actions are being led primarily by potentially responsible parties (PRPs) with EPA oversight. Remedy construction was completed in September 1997.
Ground water from the surficial aquifer is pumped from an extraction network, treated by an on-site air stripper, and discharged into Lake Miller. Ground water from the Floridan aquifer is pumped from the facility water supply well, treated by an on-site air stripper, and used as process water. Ground water continues to be monitored on and around the site on a semi-annual basis.
The future use of the site is limited by institutional controls. If soils on site are disturbed, they must be tested for chromium and disposed of properly if performance criteria are exceeded.
The remedy for Lake Miller involves ongoing monitoring and institutional controls. Additional sampling of fish tissue, sediment, and surface water occurred in November 2003. No chromium levels of concern were noted in biota. Surface water and sediment from Lake Miller is monitored on a semi-annual basis. Access to Lake Miller is restricted.
In October 1987, EPA and the PRP entered into an Administrative Order on Consent for Sherwood to conduct the Remedial Investigation/Feasibility Study as well as reimburse EPA for the costs of oversight of their investigation.
In October 1991, EPA and the PRP entered into a Consent Agreement to implement the Remedial Design and Remedial Action. The Consent agreement initiated remediation of the surficial aquifer and included the installation of the ground water extraction and treatment system.
Upon signature of the final ROD dated October 8, 1992, EPA and Sherwood negotiated the terms of an Amendment to the Consent Decree to incorporate additional requirements of the new ROD. This was signed in December 1993.
EPA has conducted a range of community involvement activities at the Sherwood Medical Industries site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices, interviews, and updates.
Long-term operation of the ground water treatment system is expected to continue indefinitely.It is expected that the ground water remedy for the surficial aquifer will need to be expanded or supplemented with additional cleanup techniques (for example, source destruction). Depending on the scope and extent of the changes to the ground water remedy, either an Explanation of Significant Differences will be issued or a ROD Amendment will be pursued.
