Federal Water Pollution Control Act In 1972, the Federal Water Pollution Control Act (also referred to as the Clean Water Act [CWA]) was amended to provide that the discharge of pollutants to waters of the United States from any point source is unlawful unless the discharge is in compliance with an NPDES (National Pollutant Discharge Elimination System) permit. Ever–evolving stormwater regulations present challenges designed to regulate point source discharges required to address specific needs and conditions of watersheds within a region. Soil pollution comprises the pollution of soils with materials, mostly chemicals, that are out of place or are present at concentrations higher than normal which may have adverse effects on humans or other organisms.

Fertile Soil  is Being Lost Fertile soil eroding faster than it can be replaced Tom Young, BusinessGreen, 04 Feb 2010 Fertile soil is being lost faster than it can be replenished making it much harder to grow crops around the world, according to a study by the University of Sydney. The study, reported in The Daily Telegraph, claims bad soil mismanagement, climate change, and rising populations are leading to a decline in suitable farming soil. An estimated 75 billion tonnes of soil is lost annually with more than 80 percent of the world's farming land "moderately or severely eroded", the report found. Soil is being lost in China 57 times faster than it can be replaced through natural processes, in Europe 17 times faster and in America 10 times faster. The study said all suitable farming soil could vanish within 60 years if quick action was not taken, leading to a global food crisis.
