| Details: | SUMMARY: Follow up to corrosion control pH samples below minimum value DETAILS: Silas discussed the 3 grab distribution system pH samples that were below the minimum 7.5 value for the July through December 2017 monitoring period. City flushed the associated area and followed with a pH sample above the 7.5 minimum value at all 3 sample locations. We discussed that a violation occurs when the system incurs more than 9 excursions (pH samples below 7.5) in any 6 month period. ACTION NEEDED: City will continue reviewing pH grab sample protocol and conduct follow up pH grab samples quickly after any future low values, to ensure water quality is maintained at an acceptable pH level in the system. | ||
