And ‘safe to say that the United States, that drinking water is treated, filtered and safe to consume. After all, with the innovations in water treatment chemicals and regulations governing the EPA’s drinking water at home is certainly. Although our water is clean and safe level of spread of waterborne diseases is still a threat, and the EPA will continue to research and find new ways to protect the public health by ensuring that there are less contaminants in the water potable water.
In January this year, the EPA introduced a new rule to the Regulations National Primary Drinking Water, the long term Rule 2 Improved management of surface water. This rule requires water systems to control the levels of Cryptosporidium. It aims to improve drinking water quality and reduce the number of diseases caused by cryptography and other disease-causing microorganisms that may be present in drinking water tanks and water discovered along.
Cryptosporidium is often present in systems in which the results of the E-coli bacteria in a test than the total coliform concentration determined. The test results of total coliform bacteria are used as the primary indicator of water potability.
Microscopic parasite Cryptosporidium causes diarrheal disease, cryptosporidiosis disease. In recent years, structures for water releases have been implicated in a number of cryptosporidiosis occurred. Crypto is transmitted into the water through the feces of people or animals. Young children are very susceptible to contracting authorities cryptosporidiosis from contaminated water recreation, because they are often swallowed quantities of water while swimming. In addition, pregnant women and people with weakened immune systems are also at high risk if Crypto is a contract.
The parasite Cryptosporidium creates a challenge trying to keep the water clean and sanitized when the parasites are resistant to many chemical disinfectants, including chlorine. Filtration is currently the only way to eliminate crypto standard of water supply. Sand filtration has been shown that the best results. The water is disinfected by filtration, then it is considered supplies.
Monitoring of large water systems, the management of 100,000 people, Cryptosporidium will begin in October this year, according to the EPA LT2 rule. Smaller systems serving fewer than 10,000 people will not need to begin monitoring until October 2008. This monitoring is an extension of the current regulations, in addition to increasing the level of protection of drinking water.
