What is non-point source pollution and how does it impact the lake?
Non-point source pollution refers to water pollution that does not originate from a single clearly identifiable source like a pipe from a factory into a water body. Non-point source pollution originates over a broad area and a variety of sources and can be in an urban or rural setting. Examples of non-point source pollution include: sediment from construction sites, uncovered salt storage from highway operations, leachate from septic tanks, agricultural runoff of sediment or manure, fertilizer or pesticides from farms and residential lawns, street litter, and petroleum products from automobiles. These pollutants can be carried into area streams and lakes via runoff or transported to street drains through wind, rain, and snow and then carried into waterways. Because of its dispersed sources, non-point source pollution can be more difficult to control. It’s also more difficult to assess impacts on the lake’s water quality from nonpoint sources than from point source pollution. The extent
