Welcome to Current TV
The EPA is asking for comments on whether or not Water Storage Tanks and Towers should be inspected & cleaned. Did you know that there are currently no requirements by the EPA for public water storage tanks (our drinking water) to ever be inspected or cleaned? So far it has been up to the individual states. Some states have no requirements at all, so water storage tanks & towers are never inspected.
Other states like Texas have rules for inspection but none for cleaning. Water utility operators can get funding for inspections but many are turned down for cleaning funds because there are no rules, laws or guidelines that require cleaning.
No rules = It's not important.
But it is important. Over time almost all water storage tanks accumulate sediment in the floor. This sediment can become a habitat for bacteria, protozoa and even viruses to get a foothold in the water distribution system. To combat the organic contaminates the water utility operators add more and more disinfectants like chlorine.
After years of adding more and more disinfectants they start to break down causing chemical byproducts like
Chloroform, Bromoform and haloacetic acid. Most if not all of these byproducts cause cancer.
The tanks did not need to be cleaned to kill some of the bacteria operators just increased the chlorine. You cant kill the chemical byproducts that caused, the only way to get rid of it is to remove the sediment in the floor of the tank that has become its final resting place. Keeping the tanks clean also reduces the need for extra disinfectant use in the first place.
The EPA uses one of the incidents in Colorado to make the case for TANK INSPECTIONS.
In March 2008, Alamosa, Colorado (population about 9,000)
experienced a waterborne disease outbreak associated with Salmonella.
The report released by the Colorado Department of Public Health and Environment (Falco and Williams 2009) indicated that the outbreak resulted in 422 reported cases of illness, 122 of which were laboratory confirmed, and one fatally. The State epidemiologist estimated that a total of 1,300 people may have been ill. Two storage tanks in Alamosa had several inches of sediment and breaches; one tank had breaches large enough for birds and animals to enter.

I also have a poll to let us know what you think.
Please forward this video to your friends and ask everyone to take my poll
We need to let the EPA know that inspecting and cleaning water storage tanks is
an important heath issue!
