What Are the Different Methods of Testing Water Pollution? 

Various tests are used to measure the quality of water. Water quality tests can also identify changes in the water over time. Some of the most common tests include turbidity, nitrate, pH, total dissolved solids, coliform, iron, copper, zinc, manganese, and hardness.

Water quality tests are used to ensure that water meets the requirements of its designated uses. Tests can also indicate whether a water source is contaminated. This information can help identify a stringent regulation or efficient water pollution prevention method. 

If the test results indicate that the water is contaminated, the source of the contamination must be identified. This can be done by calling your local environmental health department. If the water source is a private well, the owner may be able to find information on the local water quality. If the source is a public water system, the water will be checked to ensure that it meets the EPA Safe Drinking Water Act. 

Water quality tests can also detect whether a water source has a chlorine-releasing substance. Chlorine-releasing substances can be more expensive than chlorine gas. They are not used in all water sources. Typically, water with a chlorine-releasing substance will require secondary treatment. These treatments include ultraviolet treatment, chlorination, and membrane filtration. Depending on the treatment method, water may be chlorinated using chlorine gas, hypochlorites, or ozone. 

Total coliform bacteria are common in the environment. They can also be found in the intestines of warm-blooded anima and in,”  the human body. They are not harmful and can signal the presence of bacteria that may be present in human feces. The coliform bacteria test is used to determine,”     whether water is safe to drink. Having a negative total coliform test indicates that the water is safe to drink. 

Nitrate levels can be an indicator of water pollution. If the nitrate level is higher than the EPA’s safe drinking water limit, the source of the nitrate must be identified. Nitrate is often a result of manure, sewage, or nitrogen fertilizers reaching the water source. If the nitrate level is elevated, the source must be addressed and retested every seven days. 

Detecting bacteria is the most basic screening method for drinking water safety. However, the presence of bacteria does not mean that the water is safe. It is also important to note that certain bacteria may be present in water that is not contaminated. These organisms may be more resistant to disinfectants than other pathogens. However, bacteria may also be present in the water if there are other contaminant sources present, such as sewage or pollution from an industrial source. 

Water quality tests can also indicate the amount of dissolved oxygen in the water. This is necessary for many aquatic life forms to survive. Swamps naturally have low levels of DO. However, the presence of organic matter can reduce the amount of DO in water. This decrease in DO can cause taste problems and odor problems.
