Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. [3] Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [4]
In the early 20th century, communities began to install drinking water treatment systems, but control of the principal pollution sources—domestic sewage, industry, and agriculture—was not effectively regulated in the US until the 1970s. [2] These pollution sources can affect both groundwater and surface water.
One source of perchlorate in drinking water is the past production of solid rocket propellants using perchlorate, combined with poor disposal practices. Industrial accidents and agricultural fertilizers are also suspected as sources of contamination of drinking water by
Water pollution is the contamination of natural water bodies by chemical, physical, radioactive or pathogenic microbial substances. [2] Point sources of water pollution are described by the CWA as "any discernible, confined, and discrete conveyance from which pollutants are or may be discharged."
The S.C. Department of Health and Environmental Control is scrambling to assess how a tight new limit on forever chemicals in drinking water will affect utilities and the public.

These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources . [ 33 ] Point sources have one identifiable cause, such as a storm drain , a wastewater treatment plant , or an oil spill .
The drinking water of 14 communities, over 170,000 individuals, and over 150 square miles was contaminated through 3M's improper disposal of chemicals. [6] [1] Some of these communities include Lake Elmo, Oakdale, Bayport, West Lakeland Townships, Lakeland, Lakeland Shores, St. Paul Park, Newport, and Woodbury. [7]
