Well Head Protection Program (WHPP)
"The purpose of Michigan's Wellhead Protection Program (WHPP) is to protect public water supply systems (PWSS), which use ground water, from potential sources of contamination. Protection is provided by identifying the area which contributes ground water to PWSS wells, identifying sources of contamination within the area, and developing methods to manage the area and minimize the threat to the PWSS."
