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 5.1-7A.  Impaired lakes and streams with site type, name, length of impaired reach, area of impaired lake, designated use standard and parameter(s) exceeded is shown in Table 5.1-7B.  Figure 5.1-10 shows the location of water quality occurrences keyed to Table 5.1.7.  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 5.1-7A.

• Forty-nine well and spring sites have parameter concentrations that have equaled or exceeded drinking water standards

• The drinking water standard most frequently equaled or exceeded in the sites measured was arsenic.  Other standards equaled or exceeded include cadmium, fluoride and radionuclides.

Lakes and Streams with impaired waters

• Refer to Table 5.1-7B.
• Water quality standards for cadmium, copper, lead and zinc were equaled or exceeded in a 21 mile reach of Turkey Creek from an unnamed tributary to Poland Creek.
• Turkey Creek is part of the ADEQ water quality improvement effort called the Total Maximum Daily Load  (TMDL) program.  The TMDL report has been completed and the United States Forest Service has completed remediation of the Golden Belt and Golden Turkey mines, which caused the contamination.
