The importance of water quality testing really is such that it affects not only the ecology and the well being of the ecosystem as a whole but also all marine life. While most of take water for granted when it comes to their bodies of water, there are some other creatures which depend on the health of fresh water to live. The health and survival of the aquatic life depends on it.
A Management Plan must be in place before any chemical can be released into the environment. Without a management plan no regulatory standards can be implemented to control the release of chemical or biological substances. The need for water quality testing cannot be stressed enough. Before any chemical can be introduced to the environment, such tests must be conducted to determine the effects on aquatic life.
The Environmental Protection Agency or EPA seeks to regulate the use of pesticides and their byproducts in domestic and commercial production. They have set down various limitations and restrictions based on their opinion regarding the effectiveness of the pesticide and its effects on water quality. The most commonly used pesticides are the organophosphates, most of which have the ability to drift into bodies of water. Water samples taken from various locations around the country are studied by the EPA to determine the levels of these pesticides in the drinking water. Based on the results, they issue permits for the treatment and control of such pesticides.
Another group that contributes to the monitoring of this nutrient-rich water is the U.S. military. They conduct water quality testing using state-of-the-art laboratory testing equipment, to determine if biological contaminants in the cawst are harmful to the soldiers when consumed. Mobile laboratories are also used by the military to determine if soldiers are suffering from physiological problems that can result from consuming contaminated cawst. In cases where these tests detect a threat, the military issues an alert to its personnel.
Other groups involved in water quality research are the states of Colorado and Wyoming, which have responsibility for regulating fish and wildlife populations. They rely on voluntary certification programs developed by the waterbody management organizations or MPOs. A marine biology student conducts a sample check at a common place to collect information on ph levels in the waterbody. Various types of algae are present in different parts of the world and they serve as food source for various types of marine animals. Once their numbers increase, they can clog up the filters of the sewage treatment plant. Samples of these algae are taken and analyzed by the state office of water quality.
There are two important groups that are affected by the quality of surface water. These are the inhabitants of the aquatic system and those who live near the aquatic surface. Both groups need to be tested for contaminants so that they can be dealt with accordingly. When the test results indicate presence of certain contaminants in the surface water, the concerned state agency is supposed to do something about it.
The major portion of water quality testing involves the collection of samples from surface waters. The collection of samples is done through different means and the methods used may differ. However, the most common water sampling techniques include use of surface water well, surface water borehole, sub-surface thermometer, sub-surface camera and bottom flow filter.
One major part of the water testing process involves the use of oxygen dissolved oxygen sensors. Oxygen sensors are capable of determining the presence of both dissolved oxygen and total dissolved oxygen in surface water. The dissolved oxygen molecules are considered as good indicators of the health of the aquatic system. However, when they decrease in number, the system starts to show signs of deteriorating health. This can be seen from the reduction in the amount of oxygen molecules floating on the surface and in the water body itself. Therefore, this equipment is also used in other specialized forms of water quality testing as well.
