Abstract
The Township of Sparta, NJ has detected uranium at concentrations above the Maximum Containment Level (MCL) in their Alumina Hill Well No.s 1 and 2. The wells have a combined capacity of 130 gpm. The initial uranium concentration at the wells was 122 ug/L. The wells have moderate hardness with an average of 300 mg/L as CaC03. The wells contain radon at 50,000 pCi/L and under a previous project a packed tower aeration system was installed that removes the radon to less than 100 pCi/L. The combined radium 226/228 level is approximately 1.5 pCi/L, which is well under the 5.0 pCi/L MCL.
