Detailed explanation-1: -Runoff is a major source of water pollution. As the water runs along a surface, it picks up litter, petroleum, chemicals, fertilizers, and other toxic substances. From California to New Jersey, beaches in the U.S. are regularly closed after heavy rainfall because of runoff that includes sewage and medical waste.
Detailed explanation-2: -Endangering Aquatic Life: Eroded dirt from the runoff blocks sunlight from reaching underwater grasses and smothers the aquatic homes of oysters and other life. As grasses and marine life die, fish and other creatures that rely on them are placed in jeopardy.
Detailed explanation-3: -All marine debris comes from people with a majority of it originating on land and entering the ocean and Great Lakes through littering, poor waste management practices, storm water discharge, and extreme natural events such as tsunamis and hurricanes.
Detailed explanation-4: -Runoff picks up fertilizer, oil, pesticides, dirt, bacteria and other pollutants as it makes its way through storm drains and ditches-untreated-to our streams, rivers, lakes and the ocean. Polluted runoff is one of the greatest threats to clean water in the U.S.
