A collaborative system has been developed by the CDC, the EPA or Environmental Protection Agency and the CSTE or Council of State and Territorial Epidemiologists. Efforts are being made by these bodies to control the diseases caused by water pollution. This surveillance system also collects the information about the causes and effects of diseases. It is running in the US since 1971. |

The system involves states, community as well as local people to find out and investigate waterborne disease outbreaks or WBDOs. WBDO is defined if two conditions occur. First, after taking water or coming in contact with the water, two persons should show the same illness. Second criterion states that water should be one of the major causes of the disease.
Here are some statistics on water pollution and the effect of this type of pollution:
During one year, from 1999 to 2000, 25 states reported a total of 39 outbreaks. One outbreak was related to 10 states. These 39 outbreaks affected 2,068 people, and resulted in two fatalities. 22 out of the total outbreaks showed microorganisms and chemicals as one of the major causes. Out of these 22, 20 outbreaks were related to pathogens, whereas 2 were result of toxic effects of chemicals. Among 39 outbreaks, 28 were linked to groundwater and wells and lakes which were not regulated by EPA. 23 states reported total 59 outbreaks, related to the contact with recreational water. This affected 2,093 people. 36 of them showed gastroenteritis. Pools and fountains were the cause for 36 out of 59 outbreaks. From these 36, 30 introduced etiologic agent.
A clear indication by increase in water surface from 11.8 percent to 17.9 percent showed its association with the outbreaks. This occurred was from 1997 to1998.
