On Thursday, June 7, 2018, a third Tier II public notice for a non-emergency drinking water violation for haloacetic acids (HAAs) was sent to customers in the Main Lower South Water System. A Tier II public notice is a non-emergency notification because there is no immediate health risk. This is not an emergency situation, and you may continue to drink the water. In December 2017, a public notice was issued for exceedance of the HAA Standard. Sample results continue to show the levels of HAAs is less than 60ppb, however compliance is based on a locational running annual average (LRAA). For this reason, a second public notice was issued in march 2018 becasue the LRAA for two sites remained above 60ppb due to the high numbers received in November 2017. Numbers recieved in June show the levels remain below 60ppb, however one site has an LRAA over 60ppb. The LRAA for the second site is below 60ppb and is no longer exceeding the HAA Standard.
