Great Lakes Water Authority (GLWA) Monitoring Data

Public water systems sample for many different water quality indicators, also known as parameters, every day to help ensure the safety of your drinking water. The data shown in the tables below helps the City of Flint make decisions about the best way to treat the water. If more than one sample is collected per day at a particular location, the average or range of all daily samples may be shown.

This table shows water quality data for the GLWA water system. The City will use this data to make treatment decisions when the GLWA is supplying water to the City of Flint.
