Details: SUMMARY: Arsenic Exceeding MCL DETAILS: System is a small school in the Silver Falls School District. 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 works for about 1 year, and then the Arsenic levels again climbed above the MCL. Peter Paradis contacted HBH for assistance with the Arsenic levels. I previously met with Mr Paradis and a representative from Schneider Equipment, the installer of the system. I reviewed the media type and existing water quality data. I recommended comprehensive chemical/physical testing to determine if the adsorption media is proper for this application. ACTION NEEDED: Review chemical and physical testing results to determine viability of installed equipment.
