Point and Nonpoint Pollution Sources Point Sources Point-source pollutants in surface water and groundwater are usually found in a plume that has the highest concentrations of the pollutant nearest the source (such as the end of a pipe or an underground injection system) and diminishing concentrations farther away from the source. The various types of point-source pollutants found in waters are as varied as the types of business‚ industry‚ agricultural‚ and urban sources that produce them. Commercial

Although the quality of upstream river water is generally good‚ the downstream sections of major rivers reveal poor water quality‚ and most of the lakes and canals in urban areas have become sewage sinks. Many residents of Vietnam have wondered about the causes of water pollution‚ and many researchers have studied it. Accordingly‚ the two main causes of water pollution in Vietnam were the weakness in industrial wastewater management and the lack of civic

It measures at 850 cubic meters of water; it extends to about 3‚827 miles‚ measures at 206 miles across‚ and about 183 miles north to south. The average water depth in this huge lake is 195 ft. These lakes are the largest fresh water supply and home to many of the world’s wildlife. For several years the Great Lakes have served as a dumping ground for many harmful pollutants. Damage
