Pinal AMA Water Quality

Sites with parameter concentrations that have equaled or exceeded drinking water standard(s), including location and parameter(s) are shown in Table 8.2-8A.  There are no impaired lakes or streams in the Pinal AMA.  Figure 8.2-10 shows the location of water quality occurrences keyed to Table 8.2-8.  Figure 8.2-11 shows the located of contamination sites with site information shown in Table 8.2-9.   A description of water quality data sources and methods is found in Volume 1, Appendix A.  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.

Well, spring and mine sites that have equaled or exceeded drinking water standards (DWS)

  • Refer to Table 8.2-8A.
  • Three hundred and thirteen sites have parameter concentrations that have equaled or exceeded DWS.
  • Frequently equaled or exceeded parameters include nitrate, fluoride and arsenic.
  • Other parameters equaled or exceeded include cadmium, lead, radionuclides, selenium, beryllium, total dissolved solids and zinc.

Effluent Dependent Reaches

  • Refer to Figure 8.2-10
  • There are two effluent dependent reaches on the Santa Cruz River and the Gila River.

Contamination Sites

  • Refer to Figure 8.2-11 and Table 8.2-9
  • There are three Voluntary Remediation Program sites and a Resource Conservation and Remediation Act site.
