speaking_ water polution

Water. We won’t live without it. Water is life and pollution is putting that at risk.

Water pollution is a enormous issue globally and is thought to be the leading cause of deaths and disease daily.

I always was under the impression that there are only one type of pollution, but the fact is there is three types of water pollution.

Point source pollution - containments enter a waterway through a discrete transportation such as a pipe or ditch (includes sewage treatment plants, factories or a city storm drain).

Non-Point source pollution - diffuse contamination that doesn’t come from a single source. NPS pollution is a small collective of infectivity from a large area.
Examples of this type of NPS is nutrient runoff in storm water from “sheet flow” over agricultural or a forest. Contaminated storm water washed of parking lots, roads and highways (urban runoff) is also falls under this category.

Groundwater- a spill of chemical contaminate on soil, located from water bodies that may contaminate the aquifers below.
An aquifer is an underground layer of water-bearing permeable rock or unconcluded materials (sand, gravel, silt or clay) from which ground water can be removed by a water well.

To keep the point source pollution under regulation the Clean Water Act established in 1972. The law mandates the Untied States Environmental Protection Agency (EPA) to publish and enforce waste water standards.
