Water quality is measured by several factors, such as the concentration of dissolved oxygen, bacteria levels, the amount of salt (or salinity), or the amount of material suspended in the water (turbidity). In some bodies of water, the concentration of microscopic algae and quantities of pesticides, herbicides, heavy metals, and other contaminants may also be measured to determine water quality. Review journals are the evaluation of work by one or more people with similar competences as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility.
Poor water quality can pose a health risk for people. Poor water quality can also pose a health risk for ecosystems.
In the Florida Keys, good water quality is essential to a healthy marine ecosystem. Seagrass and coral reef communities thrive in clean water that is relatively low in nutrients. Too many nutrients in the water can cause excess growth of algae, which can smother corals and seagrass. Pollutants such as metals, oils, pesticides, and fertilizers run off from land into the waters, causing excess algae growth and other harmful impacts.
Within Florida Keys National Marine Sanctuary, recommendations for actions to restore and maintain water quality conditions needed to sustain healthy plant and animal populations are generated through the Water Quality Protection Program.
There are things you can do to prevent degradation to sanctuary waters, such assupporting and participating in advanced wastewater treatment programs that remove unwanted nutrients and harmful bacteria, using “pump-out” stations for your vessel’s sanitation device, using as many “green” products as possible at home, and reducing or eliminating the use of fertilizers, herbicides, and pesticides.
