Littoral zone

In coastal environments the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. It always includes this intertidal zone and is often used to mean the same as the intertidal zone. However, the meaning of "littoral zone" can extend well beyond the intertidal zone. There is no single definition. What is regarded as the full extent of the littoral zone, and the way the littoral zone is divided into subregions, varies in different contexts (lakes and rivers have their own definitions). The adjacency of water gives a number of distinctive characteristics to littoral regions.

The word "littoral" is used both as a noun and an adjective. In oceanography and marine biology[edit] In oceanography and marine biology, the idea of the littoral zone is extended roughly to the edge of the continental shelf.

Taste and odor, although undesirable, are generally not considered unhealthy. In recent years, however, activated charcoal filters have been used to remove some of the contaminants that have been discovered in water supplies. Activated charcoal is most effective at removing organic compounds such as volatile organic compounds, pesticides and benzene. It can also remove some metals, chlorine and radon. Because activated charcoal systems are limited in the types of compounds they can effectively remove, it is essential that the homeowner determine which water contaminants are present before purchasing such a system. Note that home water treatment is considered only a temporary solution.

Home activated charcoal treatment systems are quite simple. Physical and chemical characteristics of the water will also affect performance. Muh-31-4-6-0703-2.

Director of Aquatics, Penn State University President, Aquatic Safety Research Group, LLC Perhaps the most perplexing and controversial problem facing heavily used indoor pools today is chloramine production. Chloramines cause obnoxious odors as well as skin, eye, and respiratory irritation that many swimmers mistakenly attribute to chlorine itself. When chloramine levels become troublesome (0.3-0.5 parts per million (ppm)), people begin to complain.

It is often referred to in the plural, as “chloramines,” because it can take on a number of forms according to the pH and mineral content of the water. The whole reduction discussion for chloramines can become quite complex, but the main thing you need to know is that chloramine is removed from water with essentially the same strategies that are used to remove chlorine. This means that carbon filtration is the best removal method, and, contrary to urban legends, filter carbon does indeed remove chloramine.

Read product labels closely, and if a product states that it removes chlorine and chloramines, but has no mention of ammonia, beware.

Chloramines are most commonly formed when ammonia is added to chlorine to treat drinking water. The typical purpose of chloramines is to provide longer-lasting water treatment as the water moves through pipes to consumers. This type of disinfection is known as secondary disinfection. Chloramines have been used by water utilities for almost 90 years, and their use is closely regulated. More than one in five Americans uses drinking water treated with chloramines.

Many utilities use chlorine as their secondary disinfectant; however, in recent years, some of them changed their secondary disinfectant to chloramines to meet disinfection byproduct regulations.
