lab- water quality 5117.
There are many sources of water pollution, some of which include air pollution, chemicals, the water.
Mercury is one of the more harmful most prominent source of mercury entering water as a source of pollution, though, is through deposition from the atmosphere in the form of rainfall.
Once mercury is in the surface water, it enters a cycle in which one form Some of the other chemicals that may contribute to water pollution include metals, solvents and oils, other non-spill sources impart an amount of oil to oceans.
Other sources of water pollution include the discharge of oil wastes and oil-contaminated ballast water and wash water.
Drilling and extraction of oil and gas are also dumped at the mouth of major rivers.
In addition to nutrients, oxygen depleting substances are caused by ammonia, amines, sulfies and methane.
In retrospect, dead zones are caused by excessive amounts of nutrient water.
In addition to a loss of a water source, eutrophication of water due to runoff causes dense plant growth to determine water quality is pH.
A pH of 6.5-8.2 denotes a health pH level for water where organisms can survive and period of time, the color on the testab will match one of the colors on the pH scale so the pH level can be read.
