If you are buying a home with a shared well, you must enter into an agreement with the other users of the well to protect access to the water supply and determine the cost and responsibilities for maintaining the system. This agreement is a legal document between two parties regarding the supply of water to the well and the sharing of the cost of its supply. The supplying party shares the well water with the delivered part and all costs of repairing the supply system are shared between the parties. The agreement can be used in any U.S. state. This agreement is entered into when the property with a shared well is sold to a new owner. The process of signing the agreement will not take much time. Note: Currently, bipartite wells do not require ongoing monitoring of bacteria and nitrates. However, it is highly recommended to test bacteria at least every year and nitrates at least every three years. Systems with nitrate concentrations above 3.0 ppm should be tested more frequently.
