Radium Treatment Construction

Installation of Radium Treatment at Well 4 (Melinda Weaver Park) began in late September and will continue until fall 2018. 

The Wisconsin Department of Natural Resources (WDNR) has approved plans for radium treatment at Wells 4 and 5, the abandonment of Wells 1, 2 and 3 and the construction of Well 8. This will allow our system to be compliant with the Environmental Protection Agency’s (EPA) radium standards.

Radium is a naturally-occurring radioactive element found in Wisconsin’s groundwater. As groundwater moves through aquifers, minerals and other elements, such as radium, can be dissolved out of the rock and into the water. The WDNR and the Department of Health and Social Services advise that the immediate health risk is negligible and the EPA standards follow a goal of an extreme level of precaution. Further, if you use a water softener, which most Sussex residents do, the radium has been effectively removed by the softening process.

The Village will use the Hydrous Manganese Oxide treatment (HMO) system, which was the most cost effective alternative. Costs to treat the Village’s entire water system will exceed $6 million, with rate increases to customers being necessary to pay for the mandated treatment. The WDNR is requiring system-wide treatment by 2019. Improvements at Wells 4 and 5 began this fall, with Well 8 construction beginning later this year, and decommissioning of Wells 1, 2 and 3 in late 2019.
