Community Results Overview
In partnership with the City of Flint and the Department of Environment, Great Lakes, and Energy (EGLE), the Michigan Department of Health and Human Services (MDHHS) is supporting the current Flint water infrastructure project with the drinking water testing program. This is a program, MDHHS offers free water sampling and testing to residents in communities with current and past action level exceedances (ALEs). The program provides water quality information on residential tap water to protect public health and ensure that residents are getting clean water. Within the drinking water testing program, this activity is called the Flint Secondary Water Source Project.
Flint Secondary Water Source Project
Initial Water Sampling and Testing
The table shows the start date of the water blending between Great Lakes Water Authority (GLWA) and the secondary water source, Genesee County Drain Commissioner (GCDC). Water blending is when water from different sources is mixed. Water blending was needed during the Flint Secondary Water Source Project to ensure that GCDC water, pipes, and other hardware were ready for the back up water supply.
Water samples for this effort were collected after the blend start dates. The initial sampling activities are complete. The summarized data can be found on the Community Data Summary Results page and the All Water Quality Parameters Sample Results page. Individual household results have been mailed to the residents.

Follow-up Water Sampling and Testing
Through May 2023, MDHHS, in partnership with the City of Flint and EGLE, will complete follow-up water testing. Follow-up testing will have five sampling events, which means water samples will be collected on five different dates. These tests will help ensure that residents have high-quality water following the completion of the Flint Secondary Water Source Project.
MDHHS will continue to share summarized sampling results on the Community Data Summary Results page and the All Water Quality Parameters Sample Results page as data is processed. Individual household results will be mailed directly to residents. MDHHS will protect the privacy of individual household results to the fullest extent of the law.
Reports
MDHHS recently completed a first review of the results from the initial sampling efforts in the progress report below. MDHHS did not find any apparent changes in the water quality nor changes that may pose public health concerns.
MDHHS is continuing to analyze the data from all 13 sampling events and will develop a complete report. A report will also be developed summarize the five sampling events from follow-up sampling. All reports will be posted on this website when available.
