Chemical quality of ground water in Sacramento and Western Placer counties, California

Chemical quality of groundwater was investigated in Sacramento and western Placer Counties during the summer of 1982. Chemical analyses of water samples from 209 wells indicate that the groundwater is suitable for domestic and most agricultural uses. Water from wells near the Sacramento River and a few wells near Lincoln had high concentrations of dissolved solids and some trace elements. Although chemical water types varied, 53% of the wells had a combination of calcium magnesium bicarbonate water. More than 90% of the wells sampled had water with a low to medium sodium-salinity hazard when used for irrigation. (Author 's abstract)
