Fractured Bedrock
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)
Pumping Tests
Other (Precipitation using sodium bicarbonate)
Comments:
Injections of sodium bicarbonate began in 2003 and have been periodically applied since then.
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
The bedrock Plume has shrunk to a radius of approximately 100 feet.
