* DRMS Numeric Standards for Sulfate and TDS are 1,950 mg/L and 2,630 mg/L, respectively.
Notes — TDS has a secondary standard of 500 mg/L. Sulfate has a secondary standard of 250 mg/L. All TDS and sulfate results exceed the
secondary standards. Shaded results for TDS indicate exceedence of DRMS Numeric Protection Levels.
** DRMS Numeric Standards for Radium 226 and Radium 228 are 23.5 pCi/L and 12.3 pCi/L mg/L, respectively.
Shaded result for Radium 228 indicates exceedence of DRMS Numeric Protection Level.
Notes — Sulfate and TDS analyses performed by Accutest Laboratory- Wheatridge, Colorado.
Radiochemistry sub - contracted to Hazen Research — Golden, Colorado.
pCi/L = picoCuries per liter, mg/L = milligrams per liter, us /Cm = microsiemens per centimeter
DUP -01 = Blind duplicate of primary groundwater sample MW -002
