The water sources for NKWD are the Ohio and Licking Rivers. A source water assessment has been completed on each. The following is a summary of the susceptibility analysis that is part of the source water assessment. Several areas of concern are related to the extensive development of transportation infrastructure, the potential for spills, high degree of impervious cover and polluted runoff. Areas of row crops and urban and recreational grasses introduce the potential for herbicide, pesticide, and fertilizer use – possible nonpoint source contaminants. Bridges, railroads, ports, waste handlers or generators, and Tier II hazardous chemical users in the area introduce the potential for spills or leaks of hazardous materials into the source water. Landfills and permitted discharges are relatively high in number for a supply area. Other areas of concern include several segments of streams already assessed as having impairments, power lines right-of-way with potential herbicide use, and residential septic systems located throughout the watershed. Since the intakes are in urban areas, the threat of underground storage tanks leaking must also be taken into account. The District and its partners including the Ohio River Valley Water Sanitation Commission (ORSANCO) and Greater Cincinnati Water Works routinely monitor the source water quality and raise community awareness about watershed protection.
