• Data taken from the Bonita Pump Station on May 9 indicates a pH of 7.5 with 1.1
mg/L chlorine residual, 17.5 mg/L alkalinity, and water temperature of 10.5
centigrade,which is average for each of the reporting days this month.

file in the IWB meeting record. The press release reported that recent test results were so

copper water quality testing in March of 2020.
