The sandstone aquifer in the eastern third of the county generally can provide a sufficient supply for residential use. Questions are often raised about the quality of water from private wells, more specifically, the nitrate concentration. This range is assumed to represent natural background levels. The average test value over the 159 wells tested was just under 2.0 ppm. Summary Water availability and quality are important public concerns.
Water problems can be both costly and inconvenient.
