Site Summary:
Federal Register Notice:  June 10, 1986

Conditions at proposal (September 18, 1985): Halby Chemical Co. was a manufacturing facility in New Castle, New Castle County, Delaware. Its primary product was ammonium thiocyanate. In the early 1970s, Witco Chemical Co. acquired the operation, then sold it to Brandywine Chemical Co. in 1977. Currently, Brandywine stores finished products for distribution on the site.

From the late 1940s to August 1977, a waste water lagoon was in use behind the plant near the Wilmington Marine Terminal in New Castle. The lagoon was approximately 2 feet deep, covered 1.5 acres, and drained into the Lobdell Canal and the Christina River.

High levels of various organic and inorganic substances, including trichloroethylene, tetrachloroethylene, arsenic, cyanide, and lead, are present in water and sediment samples from the lagoon, according to EPA tests. EPA detected thiocyanate in the ground water underlying the site. Four municipal wells are part of an interconnected system that supplies approximately 150,000 people living 2 to 3 miles from the site.

Status (June 10, 1986): EPA emergency staff has assessed the site and determined that an immediate removal action is not warranted at this time.

Ground Water
Establish Ground Water Management Zone
1. A GMZ shall be established to include Halby, Potts, Port and their Environs as defined both in the text and on the attached maps, Attachment 5 and Attachment 6. Trie GMZ will consist of two distinct areas with differing restrictions on wells. The GMZ 'A' consists of the aerial extent of Halby and Potts. The GMZ 'B' consists of the Environs impacted by Halby, Potts, and Port (both in the Columbia and Upper Potomac Aquifers) regardless of ownership and is physically bounded to the west by Route 9, the northwest by the Conrail Bridge crossing the Christina River, to the Halby Chemical Federal Superftind Site and Environs, north by the Christina River, to the east at the Delaware River, and to the south by Interstate 295 and the Delaware Memorial Bridge. 2. No public or domestic water supply wells, will be allowed or permitted in GMZ 'A'. Other types of wells may be approved following joint review and approval of both DWR and DAWM. 3. No public or domestic, water supply wells will be allowed or permitted in GMZ 'B' in the unconfined Columbia Aquifer or the Upper Potomac Aquifer. Other water supply wells may be allowed and permitted in GMZ 'B' provided that the construction of the wells will prevent transport of contaminants into the deeper aquifers. Water supply wells will be allowed and permitted in GMZ 'B' in the deeper confined Lower Potomac Aquifer provided that the construction will prevent transport of contaminants down into the deeper aquifers. 4. Permits for any wells in either GMZ 'A' or GMZ "B' may be issued by DWR following joint review and approval by both DWR and DAWM.
