Water Quality in the Grand Wash Basin

Wells, springs and mine sites with parameter concentrations that have equaled or exceeded drinking water standard(s), including location and parameter(s) are shown in Table 6.2-4A.  There are no impaired lakes and streams in this basin.  Figure 6.2-9 shows the location of water quality occurrences keyed to Table 6.2-4.  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 6.2-4A.
• All seven springs have parameter concentrations of total dissolved solids that have equaled or exceeded drinking water standards.
