Project Summary: The Western Pennyroyal karst area contains numerous springs and seeps, many of which have been contaminated by pesticides and agricultural runoff. Understanding karst geology in a region is important because local geology has an impact on surface water quality; geology affects the conductivity, alkalinity, nutrients, and pH of the stream water. The springs form the base flow for 1st order streams. The water quality of the springs will in turn establish the environmental/biological conditions of the streams. While water quality can be assessed chemically, relationships to biology are more problematic. Algae, particularly diatoms, form the base of the food chain in small streams. Diatoms are a siliceous class of algae reputed for being very sensitive to chemical conditions; therefore they are seen to be a potential useful supplement to chemical analyses of water quality.
