Question

Name any two non-point sources of water pollution?

Answer 1

Hint: Water pollution is when water sources become contaminated as a result of human activities. Lakes, rivers, oceans, aquifers, and groundwater are examples of water bodies. When toxins are introduced into the natural world, water contamination occurs.

Complete answer:
Land runoff, precipitation, air deposition, flooding, seepage, and hydrologic alteration are all examples of nonpoint source emissions. Unlike emissions from industrial and sewage treatment plants, nonpoint source pollution (NPS) comes from a variety of diffuse sources. Rainfall or snowmelt flowing over and through the field causes NPS emissions.

Excess fertilizers, herbicides, and insecticides from farm lands and residential areas are examples of nonpoint source contamination. Urban runoff and energy processing produce oil, grease, and toxic chemicals. Sediment from poorly maintained construction sites, crop and forest lands, and eroding stream banks are all contributing to the problem. Bacteria and nutrients from animals, pet waste, and defective septic systems are all sources of bacteria and nutrients. Atmospheric deposition and hydromodification are also examples of nonpoint source emissions.

The two non-point sources of water contamination are salt from irrigation activities and acid drainage from abandoned mines. The best example of nonpoint water contamination is a sewage water source.
Nonpoint source contamination is the leading cause of water quality issues, according to states. Nonpoint source pollution has a variety of impacts on different bodies of water, which aren't always well understood. We do know, however, that these contaminants have negative consequences for drinking water sources, recreational activities, fisheries, and wildlife.

Note: Any source of water pollution that does not meet the legal meaning of "point source" as specified in section $502(14)$ of the Clean Water Act is referred to as a "nonpoint source."
