An article published by WATERONLINE reports that the U.S. EPA is being cut to the bone. Drinking water regulators that were already stretched thin will simply not have the resources they need to enforce drinking water regulations designed to protect the public. The EPA is being systematically deconstructed, it is more political than ever, but with everything else that is going on in Washington who even notices this?
“More than 27 million Americans are served by community water systems that do not fully meet health-based drinking water standards. Many community water systems draw their water from surface waters, but nearly half a million square miles of such waters fail to meet one or more standards for water quality, and the list is growing each year.
U.S. EPA Administrator Andrew Wheeler says that unsafe drinking water, not climate change, is the world’s greatest environmental challenge. So it should be no surprise that EPA’s budget proclaims “clean and safe water” as a central agency goal.
Multiple USEPA White papers have documented that bacteria, protozoa and even viruses can use the sediment that accumulates on the floor of water storage tanks as a habitat to grow and become a problem in water systems. One of these papers was published on June17, 2002. Titled
“Health Risks From Microbial Growth and Biofilms in Drinking Water Distribution Systems”
Many studies have identified microbes in accumulated sediments, including both pathogens and non-pathogens. These include bacteria, viruses, protozoa, algae, fungi and invertebrates. Opportunistic pathogens that have been detected, and can multiply in sediments, include Legionella and mycobacteria (van der Kooij, 2000). Some primary pathogens can also survive for some time in sediments. Hepatitis A virus survived more than four months in sediments at both 5/C and 25/C (Sobsey et al., 1986). Other opportunistic pathogens found in sediments include Pseudomonas fluorescens and Flavobacterium spp. (Berger et al., 1993). Sediments can also release nutrients into the water which stimulate biofilm growth downstream (LeChevallier, 1999b).
The paper explains there is steady inflow of bacteria, fungi, protozoa, algae, nematodes, and other microorganisms enter the distribution system.
We often find that some of the deepest sediment is found in the smaller storage tanks. Our cleaning service is priced right. We clean tanks from 3,000 to 30 million gallons. Give us a call at 817-377-4899 and we will give you a proposal designed for your specific tank.
It is amazing how many water utility professionals do not understand the threat of sediment build up in the interior of water storage tanks. Potable water tanks and towers accumulate sediment over the years they are in service. We often see tanks (weekly) that have never been cleaned. The EPA has documented that sediment in a storage tank may become a habitat for bacteria, protozoa and even viruses. Keeping your storage tanks clean should be a scheduled procedure for every water system. Unfortunately, the smaller water utility systems with fewer resources are where we see the most need. Tanks in smaller systems are much more likely to go longer between cleanings, or just never be cleaned at all. Check out our web site: www.ronperrin.com
Our crew is at our best cleaning and inspecting water storage tanks and towers.
If your tanks have not been inspected this year please call for a free quote. We offer diver, ROV or a lower cost underwater camera option. We are sure to have a comprehensive inspection that is right for you. Call today 817-377-4899.
Clean your water tanks. No mater how you do it Cleaning your water storage tanks is important. Soft sediment accumulations on the floor of your water storage tank can be an inviting habitat for bacteria, protozoa and even viruses. Keeping your tank clean will improve water quality, lower chlorine cost and reduce the chance of a RTCR violation.
Still not sure you need to clean your tank? Call us today to schedule a comprehensive inspection that will include an underwater video. See the floor of your tank on DVD.
