Hydrogeology:

Not available

Targeted Environmental Media:
  • - Fractured Bedrock

Contaminants:

The bedrock plume in 1999 was estimated to be about 350 feet long and 200 feet wide.

Major Contaminants and Maximum Concentrations:
  • - Beryllium (30 µg/L)
  • - Cadmium (58 µg/L)
  • - Chromium (31 µg/L)
  • - Lead (15 µg/L)
  • - Nickel (1,440 µg/L)
  • - Manganese (263,000 µg/L)
  • - Silver (55 µg/L)
  • - Zinc (3,600 µg/L)

Site Characterization Technologies:

  • - Pumping Tests

Remedial Technologies:

  • - Other (Precipitation using sodium bicarbonate)
Comments:
Injections of sodium bicarbonate began in 2003 and have been periodically applied since then.
Remediation Goals:

Lead 5 ug/L, cadmium 5 ug/L, Beryllium 4 ug/L, Chromium 100 ug/L, Nickel 100,ug/L, and Copper 1,000 ug/L


Status:

The bedrock Plume has shrunk to a radius of approximately 100 feet.
