Details: SUMMARY: Arsenic Exceeding MCL DETAILS: Pratum Elementary School is a small rural grade school in the Silver Falls SD. The school is a NTNC system with a daily service population of about 91 people. The well had exceeded the arsenic MCL until an adsorptive media process from Sunshine Water (Using ADI G2 Media) was installed. Arsenic levels subsequently dropped to Non Detect levels. This method worked for about 1 year and then the Arsenic levels again climbed above the MCL. Peter Paradis contacted HBH for assistance with the arsenic issue. I previously met with him and a representative from Schneider Equipment, the installed of the system. I reviewed the media type and existing water quality data. I followed up with the school district regarding latest arsenic test results. Installed system is currently meeting removal requirements after operational changes. ACTION NEEDED: None at this time.
