PROBLEM: Feed concentration of uranium in water source was as high as 370.0 ppb, exceeding MCL standard of 30 ppb. RESULTS: Pilot unit reduced uranium levels to an average of 1.2 ppb. Mountain_Water_Conifer_CO

PROBLEM: Uranium levels in water source were as high as 241 pCi/L, exceeding the MCL standard of 20 pCi/L. RESULTS: Pilot unit reduced uranium levels to an average of 0.7 pCi/L Lawrenceville_Pilot

PROBLEM: Uranium and gross alpha levels in water source were as high as 31.0 µg/L for uranium, and 45.0 pCi/L for gross alpha, both exceeding the MCL standard of 30 µg/L for radium and 15 pCi/L for gross alpha. RESULTS: Pilot unit reduced uranium levels to an average of 0.2 µg/L and gross alpha levels to an average of 3.2 pCi/L. Grand_Island_NE

PROBLEM: Uranium, arsenic and gross alpha levels in water source were as high as 99.9 µg/L for uranium, 13.5 µg/L for arsenic and 57.0 pCi/L for gross alpha; all exceeding MCL standards. RESULTS: Pilot unit reduced uranium levels to an average of 0.2 µg/L, arsenic levels to an average of 1.2µg/L, and gross alpha levels to 2.6 pCi/L. Schurz_NV

PROBLEM: Uranium, radium and gross alpha levels in water source were as high as 43.7 pCi/L for uranium, 13.6 pCi/L for radium and 85.6 pCi/L for gross alpha; all exceeding MCL standards. RESULTS: Pilot unit reduced uranium levels to an average of 2.6 pCi/L, radium levels to an average of 1.3 pCi/L, and gross alpha levels to 5.5 pCi/L. Hopewell_ Pilot_Study_Report_CONDENSED

PROBLEM: Uranium and gross alpha levels in water source were as high as 23.0 µg/L for uranium, and 20.2 pCi/L for gross alpha, exceeding the MCL standard of 15 pCi/L for gross alpha. RESULTS: Pilot unit reduced uranium levels to 0.0 µg/L throughout the study, and gross alpha levels to an average of 2.4 pCi/L. Hastings_ Pilot_Study_Report_FINALCondensed29Jan18
