Sites with parameter concentrations that have equaled or exceeded drinking water standard(s) (DWS), including location and parameter(s) are shown in Table 3.4-4A.  There are no data on impaired lakes and streams in this basin.  Figure 3.4-9 shows the location of exceedences keyed to Table 3.4-4A.   A description of water quality data sources and methods is found in Volume 1, Appendix A.  Not all parameters were measured at all sites; selective sampling for particular constituents is common. 

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

• Refer to Table 3.4-4A.
• Five sites have parameter concentrations that have equaled or exceeded DWS. 
• Equaled or exceeded parameters include arsenic, fluoride and nitrates.
