Reasons: Lead or Copper
Details: SUMMARY: LCR Excursion Alert DETAILS: I met and spoke with Dennis Schweizer about the corrosion control excursion for not meeting a minimum pH of 7.2. I explained to him that this minimum was set as an initial minimum and that he needed to make sure that the 7.2 pH could be a level that could be maintained. I told him I would send him further correspondence regarding the minimum water quality parameters that they needed to meet once I finished my review of their two 6-month lead and copper demonstration rounds and the reported pH and alkalinity data. ACTION NEEDED: System to maintain distribution and entry point pH at 7.2 or above. DWP to notify water system of future requirements.
Associated Alerts: LCRE11212 - 05/24/2010 - LCR EXCURSION
