What Might Be in the Groundwater You Drink?

If you are a private residential well owner, it is important to understand what contaminants may be in the groundwater that you use for drinking water. Both natural and human-made contaminants can sometimes be found in groundwater. When you know what contaminants may be in groundwater and where they can be in our environment, you can help protect your drinking water and health.

    In Michigan, contaminants in groundwater can vary depending on where you live. Some parts of the state are known for having higher levels of certain contaminants than others.

Contamination sources include airports and military bases, manufacturing facilities, unlined landfills, and farm field applications.Human activity may contribute to contamination of the environment. When chemicals are released into the environment, they can seep into groundwater.
     
    Common human-made contamination sources are manufacturing facilities, agricultural runoff, and waste disposal. While these sources have the potential to contribute to contamination, precautions can be and often are taken to prevent contamination from these sources.

Protect Michigan's Groundwater

As a state, community, and individuals, we can all help protect Michigan's groundwater. Let's work together to ensure we have safe groundwater to use for drinking!

 

Michigan Initiatives

There are some initiatives in place to improve water quality around our great state! These are just a few:

Community

As a community, we can all protect our environment, and our drinking water sources!

So many communities have activities and programs in place that residents can get involved in! Learn about easy ways that you can step up for your environment within your community.

Private Residential Well Owner

As a private residential well owner, having a well means you are responsible for your own water system!

This includes protecting the groundwater used for drinking, taking care of your well system, testing your drinking water, and understanding your test results to make the best decision for your health.

Learn more about these activities!
