2. Your local land use commissioners, such as zoning and planning boards, should be carefully reviewing any applications that could affect water supplies: For example, while you may want to have a big box store built in your town, care must be taken to protect wetlands and aquifers. Large expanses of impermeable surfaces (parking lots) divert storm water in such a way as to potentially harm nearby water supplies. In addition, gasoline, oils, and other chemicals may also be washed into the water supply.
3. Stormwater treatment systems: Developers should always submit (to land commission boards) detailed storm water treatment systems to minimize any potential harm to water supplies.
4. The creation of man-made wetlands: It often helps to support water supplies when wetlands must be diverted or removed, but it is important to remember that man-made wetlands can rarely do the job of wetlands that naturally occur.
5. Buying and protecting watershed lands: The more protected land you have, the greater your town’s ability to have a healthy water supply.
