Water Quality in the Verde River 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 5.5-7A.  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  5.5-7B.  Figure  5.5-9 shows the location of water quality occurrences keyed to Table 5.5-7.  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 5.5-7A.
  • Four hundred and twenty sites have parameter concentrations that have equaled or exceeded drinking water standards

  • The parameter most frequently equaled or exceeded in the sites measured was arsenic. 

  • Many of the wells in the Payson area equaled or exceeded the standards for arsenic, beryllium, cadmium, lead, semi-volatile organic compounds and selenium.

  • Other parameters equaled or exceeded in this basin include fluoride, nitrates and total dissolved solids.

Lakes and Streams with Impaired Waters

  • Refer to Table 5.5-7B.
  • Water quality standards were exceeded in three lakes in the basin and five stream reaches on three streams.

  • Three stream reaches, totaling 37.5 miles, on the Verde River exceeded the water quality standard for turbidity. 

  • Whitehorse Lake and Pecks Lake exceeded the standard for dissolved oxygen and Stoneman Lake exceeded the and pH standard.

  • East Verde River, Oak Creek, Verde River, Pecks Lake and Stoneman Lake are part of the ADEQ water quality improvement effort called the Total Maximum Daily Load (TMDL) program.  Final TMDL reports have been completed for the lakes and all impaired reaches except for East Verde River which is under investigation.

  • Whitehorse Lake is not part of the TMDL program at this time.

Effluent Dependent Reaches

  • Refer to Figure 5.5-9
  • There are three effluent dependent reaches.  American Gulch near Payson, Bitter Creek near Jerome and Jacks Canyon Wash south of Sedona.
