The Source Water Protection Program prevents increased risk to the public water supply by regulating the quantity and use of chemicals by businesses located in the Multi-Jurisdictional Source Water Protection Area. This is accomplished through chemical inventory reviews, periodic facility inspections, and financial incentives to businesses.
Public Health staff also provides technical assistance to officials of Harrison Township, the cities of Riverside, Vandalia and Huber Heights. The city of Dayton operates a parallel program within the Dayton corporation limits.
Note: If located within Harrison Township, Riverside, Vandalia, or Huber Heights, call Public Health staff. If located within Dayton city limits, call Dayton Division of Environmental Management.
The Program helps protect the Great Miami Buried Valley Aquifer, one of the most productive sources of groundwater in North America.
The Great Miami Buried Valley Aquifer:
- Gallons of water stored: 3 trillion
- Drinking water consumers supplied: nearly 400,000
- Chemical inventory reductions since beginning of Program: 17,000,000 lbs.
How is this program beneficial?
The Sherwin-Williams paint warehouse fire in 1987 demonstrated that it is very risky to store chemicals over the area’s primary drinking water supply. Since 1988 the program has overseen a 17 million pound permanent reduction of chemicals stored in the Source Water Protection Area.
What and where is the Source Water Protection Area?
It is a water-bearing zone around the City of Dayton well fields where spilled chemical contaminants would reach public water supply wells within one year. It includes parts of Dayton, Riverside, Harrison Township, Huber Heights, Vandalia and Wright Patterson Air Force Base.
What materials are regulated by the Source Water Protection Program?
The regulations restrict substances which have a Material Data Safety Sheet indicating a health hazard. As a rough rule of thumb, nearly any substance which you should not eat or drink would be regulated.
Are chemicals at my home restricted by the Source Water Protection Program?
No. Private residences are exempt from the regulations. However, homeowners should also practice proper storage, handling and disposal of potentially harmful chemicals.

Consult with Source Water Protection staff and local zoning officials to ensure your expected chemical needs will not exceed the limits for the property.

Yes, but you may not increase your chemical inventory above the maximum established for the property.
