Ron Perrin Clean Water Tank Project elevator pitch, why I started this in about a minute!

Our Mission: To promote the safe inspection & cleaning of water storage tanks and towers with:  1) Publications, 2) Video projects, 3) Safety training and 4) Support research to explain the dangers hidden in tank sediment and the need to remove it from tanks.

Our fundraising efforts for this project will help fund education of safe water system practices for smaller at risk systems, like this one.  The purpose of our organization is to highlight the need for clean public water storage tanks.  Cleaning tanks is something that is often overlooked in smaller systems.

The need for training is real.  Again this week we found tanks that have not been cleaned in over a decade!  Tanks in many smaller systems simply fall through the cracks, going year after year, Out of Sight, Out of Mind, and there simply is not enough education on this subject.

Please take another minute to check out our blog and take our poll: Lower on the page at

In July of 2010 the EPA requested comments on proposed changes to the

Total Coliform Rule.  The entire posting can be read on this link.

Federal Register / Vol. 75, No. 134 / Wednesday, July 14, 2010 / Proposed Rules

See my post: EPA considering requiring all Water Storage Tanks to be cleaned!

Published 7-17-2010, I highlighted the relevant parts of the Federal Register post from July 2010.

The EPA is currently doing a study on the cost or requiring all potable water tanks and towers in the U.S. to be inspected and cleaned.

On May 22, 2013 we were contacted by The Cadmus Group and ask to participate in a survey on water tank inspection and cleaning.

I have made an inquiry to he Cadmus Group as to the progress of the survey, I am currently waiting for a reply.  You can explore my former post from 2010 (linked above) to get a good idea of how this came about and why the EPA thinks there is a need for a national rule.

Do you want to know more about YOUR LOCAL DRINKING WATER?  START HERE: http://water.epa.gov/drink/local/

Tap water in 42 states is contaminated with more than 140 unregulated chemicals that lack safety standards, according to the Environmental Working Group’s (EWG’s) two-and-a-half year investigation of water suppliers’ tests of the treated tap water served to communities across the country.

In an analysis of more than 22 million tap water quality tests, most of which were required under the federal Safe Drinking Water Act, EWG found that water suppliers across the U.S. detected 260 contaminants in water served to the public. One hundred forty-one (141) of these detected chemicals — more than half — are unregulated; public health officials have not set safety standards for these chemicals, even though millions drink them every day.

EWG’s analysis also found over 90 percent compliance with enforceable health standards on the part of the nation’s water utilities, showing a clear commitment to comply with safety standards once they are developed. The problem, however, is EPA’s failure to establish enforceable health standards and monitoring requirements for scores of widespread tap water contaminants. Of the 260 contaminants detected in tap water from 42 states, for only 114 has EPA set enforceable health limits (called Maximum Contaminant Levels, or MCLs), and for 5 others the Agency has set non-enforceable goals called secondary standards. (EPA 2005a). The 141 remaining chemicals without health-based limits contaminate water served to 195,257,000 people in 22,614 communities in 42 states.

To date only the State of Florida has set standards for cleaning water storage tanks.  Not only should standards be set for additional contaminates I thisnk is is just as or pehaps more important that standards be set for keeping tanks clean.  At this time it is just not understood how much sediment accumulates in an average water storage tank over a few years.  That sediment becomes a habitat where bacteria and other contaminates can thrive. 

Once in your tank bacteria can grow rapidly if it finds a place to hide from the treatment chemicals sent to destroy it.

See the video; Bacteria Growth  http://current.com/items/89137743_bacteria_growth

The EWG’s report also points out that “90 percent compliance with enforceable health standards on the part of the nation’s water utilities, showing a clear commitment to comply with safety standards.” If standards are put in place giving water utilities a time table that water storage tanks should be cleaned and or inspected the water utilities will comply.  For the most part they or the people controling their funds do not understand the improtance of inspection & cleaning. 

Even after the Environmental Working Group’s (EWG’s) two-and-a-half year investigation of water suppliers’ tests of the treated tap water served to communities across the country.  No one looked at the effects of Sediment in the water storage tanks.  It apparently was not an issue, never thought of,  the investigation only looked at reports of what the water utilitys found in their systems.

Keeping your water storage tanks clean may be one of the most overlooked maintenance procedures in the water industry.  Out of sight and out of mind, sediment in the bottom of your water storage tanks is never seen and rarely thought of. 

In 2002 The EPA Office of Ground and Drinking Water issued a paper on distribution systems titled “Health Risk From Microbial Growth and Biofilms in Drinking Water Distribution Systems”.  See the link below to read the full report.

That report sited –

Hepatitis A is a  primary pathogen that has been documented to survive more than four months in the sediment of a potable water storage tank.  

 

Bacteria, protozoa, and viruses can find sediment in the floor of a water storage tank an inviting habitat.

 

So if the EPA knows all of this why are most water storage tanks so dirty?  Like most thisngs in comes down to MONEY.

If you live in a new progressive community the likelyhood of your water storage tanks being inspected and cleaned on a regular basis is much better than if you are in a older, smaller and les affluent community.  If regulations are put into place money would need to follow to allow ecanomically depresed communities to maintain there systems properly.

 

I have been inspecting and cleaning water storage tanks since 1992.  What I have seen is the more ecanomically depresed  the community is the more likely they are to need their tanks cleand.  They are also more likely to drink more tap water.  I would think that the more affluent a community the more bottled water is consumed.  So we end up with the people who need clean tap water the most getting it the least.   I have found something important to do but I cand only help a very small % on my own. The health concerns associated with sediment in the water supplies are much biger than I am.   It is bigger than papers written and published by the EPA detailing the problem. It will take the general public to be concerned and perhaps a little sikened and outraged wouldnt hurt.  It will take people like you and me making noise and getting attention on this subject before the proper action will be taken. The Mission of this blog is to make some noise on this subject.  Let me know what you think.

The EPA has published many reports on this subject.  The work has been done to establish the problem.  Its up to us to make sure something gets done about it. 

Hope to hear from you soon
