City of Burlington Water is Now Fully Compliant with and Exceeding Consumer Safety Requirements

The City of Burlington has received good news regarding recent water quality testing results. Two of our initiatives at the Water Treatment Plant (basin cleaning and a pilot aeration study) have helped us provide water that is now fully compliant with and exceeding consumer safety requirements in all categories, including TTHMs that were previously non-compliant.

With Quarter 2 TTHM Sampling of the two samples sites, the City has regained compliance based on the Locational Running Annual Average (LRAA). The actual sample results were the best Q2 Results the City has ever obtained. This has allowed our average to decrease to a level under the MCL of 80 ppb. To recall, the LRAA calculation is based on four completed quarters of monitoring results.

The Water Treatment Plant recently installed a pilot aeration system which we believe contributed to these great results. City Water Department maintenance projects, including the cleaning of the flocculators and sedimentation basins, along with basin screw collector rehabilitation, were completed prior to our latest round of sampling, and appear to also have helped the City regain compliance.
