Point-Source Pollution
Underground aquifers are the commonest source for well water.Underground aquifers are the commonest source.
The water table was polluted by the pollution source due to rainfall or ground water contamination near the pollution site.
Water pollution, it can cause serious problems like industrial wastes can.
Groundwater pollution.
An underground source of water, such as an aquifer, is formed when water percolates through permeable rock or soil and is stored in underground reservoirs. Wells can access this water by drilling down to the level of the aquifer and using a pump to bring the water to the surface. This underground water source is replenished through natural processes like rainfall and snowmelt.
fertalizer runoff
Sources that have water, mainly piped water from a single point.
Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. The term "nonpoint source" is defined to mean any source of water pollution that does not meet the legal definition of "point source" in section 502(14) of the Clean Water Act.
An aquifer is an underground fresh water source.
