Water Quality Report

BWL releases an annual water quality report to government agencies, customers and the public. We're proud to announce our water continues to meet or exceed all EPA standards.

BWL Water Quality

The Lansing Board of Water & Light takes pride in the water we provide to our customers. We have a great team of highly qualified water professionals monitoring the water quality of our raw, conditioned and distributed water. We are proud that our drinking water supply continues to meet or exceed all quality standards established by the U.S. Environmental Protection Agency (EPA) and the Michigan Department of Environment, Great Lakes, and Energy (EGLE).


The BWL runs a variety of tests on the raw, conditioned and distributed water multiple times a day. Tests for bacteria, softening parameters, inorganic and organic compounds are performed in our laboratories to maintain the quality of your water. The BWL performs over 240,000 water quality tests per year at the water conditioning plants and over 16,000 tests in our environmental lab to track more than 100 common contaminants.

Water Source

The BWL draws its water from the Saginaw Aquifer, a groundwater supply that has been called one of the finest natural sources of groundwater in the United States. Learn how the groundwater moves through our plants and reaches your tap in this in depth video here.

Lead Information

At BWL, we take every measure to ensure our customers and community are provided with safe, lead-free drinking water. Your health and well-being is our highest priority.

Emerging Contaminants

We routinely collect and test samples of our water supply to monitor emerging contaminants and provide valuable data to government agencies. 

Water Supply, Conditioning & Distribution

Before water reaches our customers, it goes through a complex process of conditioning and distribution through our water treatment facilities.
