Details:	SUMMARY: Corrosion Control DETAILS: The Valley Inquiry Charter School (formerly Hazel Green Elementary School) has a well sourced water system which serves 110 students and staff. The Circuit Rider was contacted in 2011/2012 by the Salem-Keizer SD to provide assistance with Lead and Copper Level Exceedences (from September 2011) and associated corrosion control or other actions. Previously provided recommendations to District Staff which included the addition of orthophosphate for corrosion control or the possibility of aeration. Rather than undertaking treatment, the school chose to replace piping and fixtures. Lead and copper tests in 2012 and 2013 were below action levels. However, the testing in September 2014 had both lead and copper levels above the action level. Reviewed previous corrosion control effort. Met with Vonnie Good to determine the next course of action. Began investigation of aeration systems which may effectively increase pH through CO2 removal. ACTION NEEDED: Provide costs for CO2 stripping systems.
