Frequent Questions

What are some natural sources of organic matter (a disinfection byproduct precursor) in ground water?

In ground water, there are three main natural sources of organic matter: organic matter deposits such as buried peat, kerogen, and coal; soil and sediment organic matter; and organic matter present in waters infiltrating into the subsurface from rivers, lakes, and marine systems (United States Geological Survey, water.usgs.gov/ogw/pubs/ofr0289/ga_organic.htm).
