Wisconsin Groundwater Overview
Groundwater is perhaps the most crucial part of having a well. According to the Wisconsin DNR, around two thirds of those living in Wisconsin are using groundwater for their drinking water supply. But what exactly is groundwater, and how does one properly utilize it safely within a home?
Part of the natural water cycle, groundwater occurs when water accumulates in the cracks of fractured rocks and between soil particles. These areas, called aquifers, are typically made of sand, gravel, sandstone, or broken rocks like limestone. Due to the large connected spaces, which make these areas permeable, water can pass through these materials. The size of these spaces determines how fast the water will flow through the substance.
Groundwater is present nearly everywhere, however, how easily it can be found is determined by the local water table. It can be very close to the surface, or deep under ground. The water table can fluctuate depending on a number of factors such as melting snow and heavy rains causing it to rise, or heavy usage via groundwater pumping causing it to fall. Additionally, heavy rain and melting snow can recharge the supply of ground water, refilling aquifers via seeping down between cracks in soil and rocks.
Springs, lakes, and streams are natural sources of groundwater. Additionally, groundwater can be accessed via drilling into the supply and establishing a well. Wells can be fed via pump or the natural filling of them through pressures such as in artisan wells.
If the materials above an aquifer are permeable, this can lead to pollutants leaching into the ground water supply. Landfills, leaky underground gas tanks, septic tanks, and the overuse of pesticides and fertilizers can all contaminate groundwater supplies. Once this happens, the supply is no longer safe to drink. When planning a well, it is very important to properly survey the local water supplies. Additionally, when planning a septic system, you need to make sure that the system is properly installed and properly maintained; otherwise leaks can contaminate local groundwater sources. Properly inspecting your septic system should be performed every 1 to 2 years.
