Water Quality Conditions in the Big Sandy Basin

Sites with parameter concentrations that have equaled or exceeded drinking water standard(s) (DWS), including location and parameter(s) are shown in Table 4.1-7A.  There are no impaired lakes or streams in this basin.  Figure 4.1-9 shows the location of exceedences keyed to Table 4.1-7A.  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 4.1-7A.
  • Sixty-four sites have parameter concentrations that Frequently equaled or exceeded parameters include radionuclides, fluoride and lead
  • Other parameters commonly equaled or exceeded in the sites measured in this basin were arsenic, antimony, beryllium and cadmium.
