City of Flint Distribution System Monitoring Data
What results does EGLE look at?
EGLE looks at many different results. The four categories shown on this page (pH, Orthophosphate, Iron, and Chlorine) are main indicators of whether the City's corrosion control treatment is working properly. In 2017 EGLE set required ranges for pH and orthophosphate.
Having a small number of sample results outside the required ranges does not necessarily indicate a problem. This just means the City may need to adjust its treatment to bring the water back into the required ranges.
An expanded data set is available for people looking to make additional analyses on the water quality monitoring data.
Some data in the table is informational only, and some data shows whether target ranges for pH, orthophosphate, chlorine, and iron are being met.
Other testing that EGLE is doing for the City is Lead and Copper Sequential Sampling.
The following results are for the City of Flint Distribution system.
