Testing for perfluorinated compounds in OWASA water treatment and at Cane Creek Reservoir. We are below EPA guideline: 70 ppt parts per trillion.

In 2016, the EPA established a lifetime Health Advisory Level (HAL) of 70 parts per trillion (ppt) for the combined amount of two PFASs - PFOA and PFOS - in drinking water. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are the two PFASs which have been the most extensively produced and studied.

Source Water Protection This document summarizes source water protection efforts in the Cane Creek Reservoir and University Lake watersheds. It begins with an overview of federal and state requirements and the local ordinances to meet (and exceed) those requirements. It describes land acquisition efforts to protect the watersheds, the state’s source water assessment program and its upcoming source water protection efforts. Finally, the document summarizes water quality monitoring efforts that help our water treatment plant operators make informed decisions about process improvements and track issues of emerging concern.
