Chemical quality of ground water in San Joaquin and part of Contra Costa Counties, California
Stephen K. Sorenson
1981, Water-Resources Investigations Report 81-26
Chemical water-quality conditions were investigated in San Joaquin and part of Contra Costa Counties by canvassing available wells and sampling water from 324 representative wells. Chemical water types varied, with 73 percent of the wells sampled containing either calcium-magnesium bicarbonate, or calcium-sodium bicarbonate type water. Substantial areas contain ground water...
