Differentiate between point source and non-point source pollution. Give an example of each and describe a current piece of legislation or policy designed to control each type of pollution
What will be an ideal response?
Point source pollution can be defined as pollution that comes from a specific location, often indicated by an actual outflow pipe entering a body of water. Most point sources are industrial facilities and sewage treatment facilities. The 1972 Clean Water Act requires the EPA to regulate the discharge of pollutants into waterways. Non-point sources of water pollution include fertilizer-enriched runoff from farms and golf courses. Since its original passage, the Clean Water Act has been modified/amended in recent years to accommodate new knowledge, especially as it has related to the significance and impact of non-point water pollution. There is now specific language in the CWA, requiring management and minimization of non-point sources of water pollution.
