Water Quality Conditions in the Sacramento Valley Basin

Sites with parameter concentrations that have equaled or exceeded drinking water standard(s) (DWS), including location and parameter(s) are shown in Table 4.9-7A.  Figure 4.9-9 shows the location of exceedences keyed to Table 4.9-7A as well as the location of an effluent dependent stream reach within the basin.  All community water systems are regulated under the Safe Drinking Water Act and treat water supplies to meet drinking water standards.  Not all parameters were measured at all sites; selective sampling for particular constituents is common.  A description of water quality data sources and methods is found in Volume 1, Appendix A. 

Well, Mine or Spring sites that have equaled or exceeded drinking water standards (DWS)

  • Refer to Table 4.9-7A.
  • Sixty-two sites have parameter concentrations that have equaled or exceeded DWS. 
  • Frequently equaled or exceeded parameters include arsenic, fluoride and radionuclides.  Other parameters commonly equaled or exceeded in the sites measured in this basin were beryllium, cadmium, copper, chromium, lead, nitrate and total dissolved solids.

Effluent Dependent Reaches

  • Refer to Figure 4.9-9
  • There is one effluent dependent reach in this basin, Holy Moses Wash, south of Kingman.
