Helpful USEPA Papers and Links

Here are three very helpful USEPA papers written by the Office of Ground Water and Drinking Water between 2002 and 2006.
Finished Water Storage Facilities August 15, 2002
Page 2
2.1.1 Sediment
Sediment accumulation occurs within storage facilities due to quiescent conditions which promote particle settling. Potential water quality problems associated with sediment accumulation include increased disinfectant demand, microbial growth, disinfection by-product formation, and increased turbidity within the bulk water. Instances of microbial contamination and disinfection by-product formation due to storage facility sediments are described in the Pathogen Contamination and Microbial Growth section and the Disinfection By-Product formation section, respectively.
Page 11
Comprehensive inspections are performed to evaluate the current condition of storage facility components. These inspections often require the facility to be removed from service and drained unless robotic devices or divers are used. The need for comprehensive inspections is generally recognized by the water industry. AWWA Manual M42 (1998) recommends that tanks be drained and inspected at least once every 3 years or as required by state regulatory agencies. Most states do not recommend inspection frequencies thereby leaving it to the discretion of the utility. States that do have recommendations are Alabama (5 years), Arkansas (2 years), Missouri (5 years), New Hampshire (5 years), Ohio (5 years), Rhode Island (external once per year; internal, every five years), Texas (annually), and Wisconsin (5 years). Kirmeyer et al. (1999) recommend that comprehensive inspections be conducted every 3 to 5 years for structural condition and possibly more often for water quality purposes.
Page 12
Kirmeyer et al. (1999) recommended that covered facilities be cleaned every three to five years, or more often based on inspections and water quality monitoring, and that uncovered storage Prepared by AWWA with assistance from Economic and Engineering Services, Inc. 12facilities be cleaned once or twice per year. Commercial diving contractors can be used to clean and inspect storage facilities that cannot be removed from service. AWWA Standard C652-92 provides guidelines for disinfection of all equipment used to clean storage facilities.

Health Risks from Microbial Growth and Biofilms in Drinking Water Distribution Systems June 17, 2002
Page 26
G. Sediment Accumulation
Significant microbial activity may occur in accumulated sediment (USEPA, 1992b). Organic and inorganic sediments can also accumulate in low-flow areas of the distribution system, and enhance microbial activity by providing protection and nutrients (USEPA, 1992b). Biofilms that slough can accumulate in the periphery of distribution systems leading to sediment accumulation and the proliferation of some microorganisms (van der Kooij, 2000). Sediments may be an important source of nutrients in open finished water reservoirs, by accumulating slowly biodegrading materials which are then broken down and released into the water column (LeChevallier, 1999b). The opportunities for biofilm development may be more abundant in storage tanks than in distribution system piping. Frequently, water is drawn from storage tanks only when water demand is high, such as during drought, fire flow, and flushing operations. This intermittent use results in prolonged storage times that may lead to increased sediment accumulation and lack of a disinfectant residual in the finished water storage vessel. Biological and aesthetic effects can be observed following the release of accumulated sediments from low flow areas of the distribution system (Geldreich, 1990).
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 andmycobacteria (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).
Page 34
I. Proper Storage Vessel Management and Alteration
Proper storage vessel management and alteration, when necessary, can prevent contamination of the distribution system. Following TCR violations in 1996 in Washington D.C., one measure that proved effective in bringing the system back into compliance was the cleaning, inspection and disinfection of storage tanks and reservoirs (Clark, et al., 1999). To reduce pathogen presence and biofilm development, systems should have a scheduled program to rehabilitate all water storage facilities (USEPA, 1997). Proper operation and maintenance of storage tanks and reservoirs is listed as a BAT in the TCR (USEPA, 1992b). Storage tanks and standpipes should be pressure flushed or steam cleaned, then disinfected before returned to service (USEPA, 1992b), preferably with a disinfectant solution. This may not only remove microbial contamination from the vessel’s inner surface, but also nutrients that may be present. Proper operation of storage vessels can also reduce excessive residence times, which can lead to microbial survival and growth, and biofilm formation. Properly designed inlets and outlets, and the overall system design can improve problems caused by dead ends (Trussell, 1999). Pathogen contamination due to air introduction can be reduced by installing air filters to guard against pollution entering covered water reservoirs (USEPA, 1992b). Covering finished water reservoirs can protect against contamination from airborne sources, surface runoff, accidental spills and animals, such as insects and birds (USEPA, 1992b). EPA’s Uncovered Finished Water Reservoirs Guidance Manual describes recommended contamination control measures related to birds and other animals, human activity, algal growth and insects and fish (USEPA, 1999b). An understanding of the storage hydraulics and operation is important in reducing contamination of the finished water.

CBS 11 i-Team watches as my company inspects and cleans a north Texas water tower.

November 20, 2014 Leave a comment

November 7th, 2014, Ginger Allen and the CBS 11 i-Team watches as my company inspects and cleans a north Texas water tower. The tower was cleaned as a normal maintenance procedure. A light- brown dusting of sediment was removed from the interior floor before it could get deep enough to support bacteria and become a problem.   OLYMPUS DIGITAL CAMERA The tower was cleaned by a Commercial Diver who was trained at OCEAN CORP, Houston, Texas. The Diver is sealed in his own environment, then washed down with a chlorine solution. Because we specialize in the inspection and cleaning of Potable Water Storage Facilities, all of our equipment is purchased for, and only used in, potable water. This utility is doing a great job of maintaining their system. However, utility managers across the country struggle to get the funds to properly maintain their systems. The EPA is currently considering a regulation that would require all water storage facilities to be inspected and cleaned at regular intervals. This new requirement could improve the water quality for millions of Americans.

The EPA is considering New Rules for tank Inspection & Cleaning

July 26, 2010 Leave a comment

On July 14th 2010 the The U.S. Environmental Protection Agency  Posted this notice under / Proposed Rules

2. Storage Tank Inspection and Cleaning

EPA requests comment on the value and cost of  periodic storage tank inspection and cleaning . There are instances of storage tanks being the source of waterborne disease outbreaks at PWSs. In December 1993, aSalmonella typhimurium outbreak in Gideon, Missouri resulted in over 600 people affected by diarrhea, 31 cases of laboratory-confirmed salmonellosis and seven deaths of nursing home residents who had exhibited diarrheal illness (four deaths were confirmed by culture). The larger of the two storage tanks had a breach in the roof hatch that allowed pigeon droppings to be carried into the tank and likely accumulated in the several inches of sediment. This contaminated sediment, more than likely, was pulled into the distribution system by a flushing program that  drained the tank (Clark et al. 1996). Salmonella typhimuriumwas isolated from the sediment of one of the towers, and tap water tested positive for fecal coliforms (CDC 1996). In March 2008, Alamosa, Colorado (with a population of about 9,000 people) experienced a waterborne disease outbreak associated withSalmonella. The report released by the Colorado Department of Public Health and Environment (Falco and Williams 2009) indicated that the outbreak resulted in 442 reported cases of illnesses, 122 of which were laboratory confirmed, and one fatality. 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. Some of the key factors that contributed to these two outbreaks include significant levels of sediment (several inches to feet) and the presence of breaches of the integrity of the storage tank. Sediment accumulation occurs within storage facilities due to quiescent conditions which promote particle setting. Over time sediment continues to accumulate in a tank, even if the finished water is consistently treated tobelow 0.1 nephelometric turbidity unit(NTU). For surface water systems, it isnot uncommon to have 1⁄4 to 1⁄2 inch or more of sediment accumulate after two to three years (Kirmeyer et al. 1999).

While there are no turbidity regulations for ground water systems (except for ground water under the direct influence of surface water (GWUDI)), the levels of turbidity can be significant in the water pumped from an aquifer. Sand particles, if allowed to accumulate, provide pore spaces that house diverse populations ofbiota (which may include pathogenic microorganisms) (Kirmeyer et al. 1999; van der Kooij 2003). Periodic high flows in the storage tank may scour, stir up, and suspend the sediment (along with entrapped bacteria and pathogens) and carry it into the distribution system, with greater accumulation of sediment being a more significant concern. Other water quality problems associated with sediment accumulation include increased disinfectant demand and disinfection byproduct formation. The storage tank’s vulnerability to contamination increases when breaches of the storage tank allow insects, animals, and birds and their associated diseases to enter. Contamination from bird and other animal excrement can potentially transmit disease-causing organisms to the finished water.  Waterfowl, for example, are known carriers of many different waterborne pathogens including Vibrio cholerae(Ogg et al. 1989). Based on the potential public health implications associated with poorly maintained storage tanks (e.g., as indicated by significant sediment accumulation and breaches), EPA is interested in receiving comments and supporting information regarding the state and condition of tanks that have been cleaned and inspected, costs of storage tank inspection and cleaning, and how public health can be better protected. EPA requests information on whether there are States that recommend or require periodic inspection and cleaning of storage tanks. If so, what are the requirements, the frequency of inspection and cleaning, and how successful are they? Are inspections and cleaning done by individual PWSs or by contractors?

We are adding a Registered P.E. to our staff to meet water tank inspection requirements in Florida.  Our search for the best qualified P.E. has allowed us to have contacts with Professional Engineers in most states.  If you require a Professional Engineers Evaluation of your water storage tank please contact us.  Provide us with a scope of work to be preforemd or we will assist you in developing you scope of work request so you get the inspection you need.

Ron Perrin Water Technologies has provided the best Non-Engineering visual inspection reports on potable water tanks since 1997.  Or inspections document all AWWA and state required inspection points with digital photos and underwater video, professionaly narrated and divifered in a binder that incluces a certification of inspection, printed report and  the video on a DVD format.

The underwater video is available from three different sources.  Our most popular is the  most remote under water tank inspection camera,  next our Remotely Operated Vehicle (ROV) provides more information on larger facilities and if needed we can deploy a potable water diver.   Our non-engineering inspections are the best way to meet annual visual inspection requirements required by some states.

When a more comprehensive report is required our seasoned potable water tank inspectors work under the supervision of our PE to safely collect the information needed while the water system remains in service.

For the inspection you need at a price you can afford call Ron Perrin Water Technologies  1-888-481-1768
