Water Quality in the Lake Havasu Basin

Sites with parameter concentrations that have equaled or exceeded drinking water standard(s) (DWS), including location and parameter(s) are shown in Table 4.5-6A.  There are no impaired lakes or streams in this basin.  Figure 4.5-9 shows the location of exceedences keyed to Table 4.5-6A.   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.  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 4.5-6A.
  • Twenty sites have parameter concentrations that have equaled or exceeded DWS. 
  • The most frequently equaled or exceeded parameter was nitrates.
  • Other parameters equaled or exceeded in the sites measured in this basin were arsenic, chromium and organics.
