Behind the Scenes of Public Water Storage

Robert Perrin May 2009

To raise money to go on a mission trip to Africa earlier this year my son Robert Perrin made a short documentary about Public Water Storage and Ron Perrin Water Technologies.   Also see Roberts web page at www.robertstoybox.com

It is now available on amazon.com

This video shows a comercial diver inspecting a potable water storage tank.  The diver then watches a Remotely Operated Vehicle inspect part of the tank.  This video also shows a dive crew cleaning a ground storage tank.

Drinking Water Contaminants Posted by EPA

A list of possible Drinking Water Contaminants has been posted by the EPA

The link below gets you top the EPA page that has National Primary Drinking Water Regulations (NPDWRs or primary standards) are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water. Visit the list of regulated contaminants with links for more details.

http://www.epa.gov/safewater/contaminants/index.html#micro

The problem with the EPA web site it that it is constantly in motion with thousands of web pages and hundreds being added daily.  I have elected to repost the list of list of regulated contaminants here to make it easier to find when people search the web.  The EPA posted this list in June of 2003 with this identifier #. EPA 816-F-03-016.  I have personally found this information to be very hard to find when searching their site. In addition to that you never know when it will be taken down.  All the more reason to re-post it here where more people will be able to find it when searching for Drinking Water Contaminates.

Microorganisms

Contaminant	MCLG1 (mg/L)2	MCL or TT1 (mg/L)2	Potential Health Effects from Ingestion of Water	Sources of Contaminant in Drinking Water
Cryptosporidium (pdf file)	zero	TT 3	Gastrointestinal illness (e.g., diarrhea, vomiting, cramps)	Human and animal fecal waste
Giardia lamblia	zero	TT3	Gastrointestinal illness (e.g., diarrhea, vomiting, cramps)	Human and animal fecal waste
Heterotrophic plate count	n/a	TT3	HPC has no health effects; it is an analytic method used to measure the variety of bacteria that are common in water. The lower the concentration of bacteria in drinking water, the better maintained the water system is.	HPC measures a range of bacteria that are naturally present in the environment

Coli)	zero	5.0%4	Not a health threat in itself; it is used to indicate whether other potentially harmful bacteria may be present5	Coliforms are naturally present in the environment; as well as feces; fecal coliforms and E. coli only come from human and animal fecal waste.
Turbidity	n/a	TT3	Turbidity is a measure of the cloudiness of water. It is used to indicate water quality and filtration effectiveness (e.g., whether disease-causing organisms are present). Higher turbidity levels are often associated with higher levels of disease-causing microorganisms such as viruses, parasites and some bacteria. These organisms can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.	Soil runoff
Viruses (enteric)	zero	TT3	Gastrointestinal illness (e.g., diarrhea, vomiting, cramps)	Human and animal fecal waste

Notes From EPA WEB PAGE: http://www.epa.gov/safewater/contaminants/index.html#mcls

¹ Definitions:
Maximum Contaminant Level (MCL) – The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to MCLGs as feasible using the best available treatment technology and taking cost into consideration. MCLs are enforceable standards.
Maximum Contaminant Level Goal (MCLG) – The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety and are non-enforceable public health goals.
Maximum Residual Disinfectant Level (MRDL) – The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG) – The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
Treatment Technique – A required process intended to reduce the level of a contaminant in drinking water.

² Units are in milligrams per liter (mg/L) unless otherwise noted. Milligrams per liter are equivalent to parts per million.

³ EPA’s surface water treatment rules require systems using surface water or ground water under the direct influence of surface water to (1) disinfect their water, and (2) filter their water or meet criteria for avoiding filtration so that the following contaminants are controlled at the following levels:

• Cryptosporidium: (as of1/1/02 for systems serving >10,000 and 1/14/05 for systems serving <10,000) 99% removal.
• Giardia lamblia: 99.9% removal/inactivation
• Viruses: 99.99% removal/inactivation
• Legionella: No limit, but EPA believes that if Giardia and viruses are removed/inactivated, Legionella will also be controlled.
• Turbidity: At no time can turbidity (cloudiness of water) go above 5 nephelolometric turbidity units (NTU); systems that filter must ensure that the turbidity go no higher than 1 NTU (0.5 NTU for conventional or direct filtration) in at least 95% of the daily samples in any month. As of January 1, 2002, turbidity may never exceed 1 NTU, and must not exceed 0.3 NTU in 95% of daily samples in any month.
• HPC: No more than 500 bacterial colonies per milliliter.
• Long Term 1 Enhanced Surface Water Treatment (Effective Date: January 14, 2005); Surface water systems or (GWUDI) systems serving fewer than 10,000 people must comply with the applicable Long Term 1 Enhanced Surface Water Treatment Rule provisions (e.g. turbidity standards, individual filter monitoring, Cryptosporidium removal requirements, updated watershed control requirements for unfiltered systems).
• Long Term 2 Enhanced Surface Water Treatment Rule (Effective Date: January 4, 2006) – Surface water systems or GWUDI systems must comply with the additional treatment for Cryptosporidium specified in this rule based on their Cryptosporidium bin classification calculated after the completion of source water monitoring.
• Filter Backwash Recycling; The Filter Backwash Recycling Rule requires systems that recycle to return specific recycle flows through all processes of the system’s existing conventional or direct filtration system or at an alternate location approved by the state.

⁴ more than 5.0% samples total coliform-positive in a month. (For water systems that collect fewer than 40 routine samples per month, no more than one sample can be total coliform-positive per month.) Every sample that has total coliform must be analyzed for either fecal coliforms or E. coli if two consecutive TC-positive samples, and one is also positive for E.coli fecal coliforms, system has an acute MCL violation.

⁵ Fecal coliform and E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Disease-causing microbes (pathogens) in these wastes can cause diarrhea, cramps, nausea, headaches, or other symptoms. These pathogens may pose a special health risk for infants, young children, and people with severely compromised immune systems.

⁶ Although there is no collective MCLG for this contaminant group, there are individual MCLGs for some of the individual contaminants:

• Trihalomethanes: bromodichloromethane (zero); bromoform (zero); dibromochloromethane (0.06 mg/L): chloroform (0.07mg/L).
• Haloacetic acids: dichloroacetic acid (zero); trichloroacetic acid (0.02 mg/L); monochloroacetic acid (0.07 mg/L). Bromoacetic acid and dibromoacetic acid are regulated with this group but have no MCLGs.

⁷ The MCL values are the same in the Stage 2 DBPR as they were in the Stage 1 DBPR, but compliance with the MCL is based on different calculations. Under Stage 1, compliance is based on a running annual average (RAA). Under Stage 2, compliance is based on a locational running annual average (LRAA), where the annual average at each sampling location in the distribution system is used to determine compliance with the MCLs. The LRAA requirement will become effective April 1, 2012 for systems on schedule 1, October 1, 2012 for systems on schedule 2, and October 1, 2013 for all remaining systems.

⁸ Lead and copper are regulated by a Treatment Technique that requires systems to control the corrosiveness of their water. If more than 10% of tap water samples exceed the action level, water systems must take additional steps. For copper, the action level is 1.3 mg/L, and for lead is 0.015 mg/L.

⁹ Each water system must certify, in writing, to the state (using third-party or manufacturer’s certification) that when acrylamide and epichlorohydrin are used in drinking water systems, the combination (or product) of dose and monomer level does not exceed the levels specified, as follows:

• Acrylamide = 0.05% dosed at 1 mg/L (or equivalent)
• Epichlorohydrin = 0.01% dosed at 20 mg/L (or equivalent)

National Secondary Drinking Water Regulations

National Secondary Drinking Water Regulations (NSDWRs or secondary standards) are non-enforceable guidelines regulating contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does not require systems to comply. However, states may choose to adopt them as enforceable standards.

• National Secondary Drinking Water Regulations – The complete regulations regarding these contaminants available from the Code of Federal Regulations Web Site.
• For more information, read Secondary Drinking Water Regulations: Guidance for Nuisance Chemicals.

List of National Secondary Drinking Water Regulations

Contaminant	Secondary Standard

What is it ?

What is it?  It’s a video about how sediment builds up in our public drinking water supplies.  It should help you understand the importance of having your potable water storage tanks inspected and cleaned. 

Out of sight and out of mind.  The cleaning of water storage tanks remains one of the most overlooked health concerns today.  I have been showing this video to every person I can for years.  I just can’t get to enough water utility managers, water board members, mayors and city council people to make a difference.  Information is power, the right people just don’t have the right information to make the right decisions.  Everyone is cutting back and it is easy to cut back on a maintenance budget.  Tell the water utility manager to do the inspections himself.  So, year after year the water tank is inspected without seeing the inside floor of the tank.  Because an inspection contractor with an underwater camera was not in the budget.  So the sediment goes unseen and unnoticed year after year.  Inspections and cleanings would only be one or two percent of the budget.  But the money never gets allocated because the people in control do not understand the importance of it. As the economy gets worse, fewer tanks will be inspected and cleaned while more and more people will return to drinking tap water.

I need your help.

We have all seen the silly or funny ”viral videos” that make their way around the world.  This one deserves to be shared so that more people who have influence on the way water systems are managed will understand the problem.  Tanks need to be inspected. If they are dirty, they should be cleaned. It is a very simple message and one that I have spent everything I have made in since 1997 trying to get across to water managers. Please share this video with your friends and encourage them to pass it on to their water utility, city council person, or water board.  Managers just don’t know what is going on inside their water storage tanks.  Having them inspected by a professional with underwater camera equipment will let them know if they have a sediment problem.  If they have sediment, removing it is a cost-effective way of maintaining the public health of that water system.

If you don’t know about Current TV, it is a cable channel and web site that is viewer created. If your video gets enough votes they put it on TV.  My mission is to show as many people as I can the health concerns of sediment in Public Water Supply storage tanks.  This would be a great way to get my message to thousands of people at a time.  Click on my link below and VOTE me “UP!” on the right side of the page!  By helping to spread this message YOU ARE MAKING A DIFFERENCE!    Thanks for your help!

This web site is about spreading this message and educating people about the importance of inspecting and cleaning their water potable storage tanks.

Potable Drinking Water.

 

Ok for years I have been saying it wrong  POT (like a pot on the stove) able.  Now,  I have been corrected

My company Inspects cleans and Dives in poh-tuh-buhl Water Tanks. 

it is Pronounced [poh-tuh-buhl] [Origin: 1565–75; < LL pōtābilis drinkable, equiv. to L pōtā(re) to drink + -bilis -ble]  Old French, from Late Latin pōtābilis, from Latin pōtāre, to drink, from pōtus, a drink  Reference: Dictionary.com Unabridged (v 1.1) – Cite This Source – po·ta·ble   Audio Help   /ˈpoʊtəbəl/ Pronunciation Key – Show Spelled Pronunciation[poh-tuh-buhl] Pronunciation Key – Show IPA Pronunciation

Ok, Ive been saying POT-ABLE for so long I think I will just change to DRINKING WATER.  My Company

Inspects drinking water tanks with a remote camera,  we can identify problems with interior coatings, corrosion and sediment.  Sediment in patable water storage systems is a real problem.  Sediment can be a habitat for bacteria to grow.  Bacteria in a citys drinking water is not usually a good thing.  The more sediment in a water storage tank or tower, the more chance there is for bacteria to come into the system, find a place to get a foothold and grow into a problem. 

When our inspections find deep sediment in a water storage facility we offer to clean it out using commercial divers.  Divers enter the water system wearing a dry suit enclosed in their own enviroment, they are washed down with a chlorine solution meeting AWWA standards.  The diver can then remove the sediment without wasting several hundred thousands or even millions of gallons of water.  This cleaning process also get the tank cleaner than the traditional method of taking the facility out of service.  Everything that is loose on the floor is removed.  If the tank is drained the loose semi liquid sediment often compresses into a hard clay like substance making cleaning much more dificult and not nearly as effective.  See more about our Inspection and tank cleaning service at www.ronperrin.com .

We are now happy to Inspect and clean Drinking Water Tanks.

DRINKING WATER PROJECT NOTES:

We are currently looking for a Steering Committee to discuss the possibility and merit of forming a Non-Profit Organization.   Currently titled “DRINKING WATER PROJECT” : Our current outline in listed below:  A non-profit Organization dedicated to the education of potable water hygieneThe importance of INSPECTING AND CLEANING POTABLE WATER The Problem:Municipal water treatment plants in the United States spend millions upon millions of dollars each year to produce clean safe drinkable water.  Unfortunately in far too many cases the clean water is then pumped into storage tanks that are rarely if ever cleaned.Sediment build up from inches to feet in the floor of the tank becomes a habitat where bacteria and other contaminates can hide and multiply.  Keeping the sediment removed from water storage tanks is often overlooked.  Keeping water storage tanks clean should be a standard maintenance procedure. The solution: Education of government officials form public works directors to water board members to  the general public. Our Mission: Legislation – Lobbying congress to mandate the U.S. Environmental Protection Agency to require all water systems INSPECT THEIR SYSTEMS YEARLY and clean their storage tanks at least once every three years. Program development-   Grants – Raise funds to assist rural and under funded systems inspect and clean their water storage systems through grants.    Education-  Educate the public as to what is in potable water storage tanks across the country and the importance of keeping them clean. Build coalition with other like minded organizations.  Educate through -    Articles    -  Direct Mail to public officials  - Trade shows  & a Speakers Bureau    If you would like to be on our steering committee, or you would like to be considered for a board position please e-mail RON PERRIN at ronlooks@aol.com be sure to put  DRINKING WATER PROJECT in the subject line.  

Have your public water storage tanks been cleaned lately?

 

Photo: Sediment being removed from Potable Water Storage Tank.

        The American Water Works Association recommends that tanks be cleaned at least every three years.  Recent focus on pharmaceuticals in water systems have made more people than ever aware of contaminates that may be lurking in their water supply.   Although pharmaceuticals in drinking water may be in the news the real threat is random bacteria and cryptosporidium spores.

The Threat of Bacteria-

Countless kinds of bacteria can make their way into a public water supply.  Chlorine and other treatment methods are our first line of defense.  When potable water storage tanks are clean small amounts of bacteria that survive the treatment process cycle through the system undetected and harmless due to the small quantity.  Sediment in the tank can capture and harbor these small amounts of bacteria.  The bacteria can start to grow hidden from chlorine deep in the sediment.  Chlorine can even be overwhelmed and depleted if a nitrate eating bacteria is collected.   As the bacteria continues to grow in the sediment month after month and year after year the threat to public health grows.       

  The Threat of Cryptosporidium

The threat of cryptosporidium outbreak is even greater with sediment in the floor of a water storage tank.   Again Sediment can harbor bacteria, cryptosporidium and other contaminates.  The best defense to insure a protozoa like  cryptosporidium will not take up residence in your water storage system may be to keep the tanks free of sediment.  In the Spring of 1993 over 100 people died as a result of a cryptosporidium outbreak that was directly associated with the Howard Avenue Water Purification Plant.  This was the largest water born disease ever documented in United States history.  It is estimated that over 400,000 people became ill with diarrhea.  

Due to the fact that cryptosporidium is a protozoa with a hard shell and not a bacteria the best defense to ensure it will not inhabit your water system is to make sure your water tanks remain sediment free.  This will remove and habitat that small amounts bacteria or protozoa could lodge and grow in, Preventing possible public health problem in the most simple way.  Keeping water storage tanks clean.    

sediment that builds up in almost all potable Sediment build up in potable water tanks can be a habitat for bacteria

 Yearly inspections of your potable water storage tanks is the best way to keep up with the sediment levels in your tank.   Since 1997 Ron Perrin Water Technologies have served water utility companies. They  offer high tech inspections using the latest generation of remotely operated underwater cameras.  Comprehensive inspections with NO WATER LOSS and NO Disruption in your service.  Our underwater camera gives you a first hand look at your water quality and allows you to make an informed decision on whether the tank should be cleaned or taken out of service for other repairs.

 CLEAN YOUR TANKS 

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.   The sediment that builds up in almost all potable water tanks can be a habitat for bacteria and other contaminates.  Bacteria can get a foothold in the sediment  out of reach of the chlorine entering the tank. Hidden in the sediment the bacteria can then grow and flourish creating a health risk. A nitrate eating bacteria can even deplete your chlorine levels leaving you at even greater risk. Removing the sediment and keeping your tank clean is the best way to maintain a healthy water system.  Divers wearing a dry suit are sealed in their own environment, they are then washed down with a chlorine solution meeting all State and AWWA requirements.  The divers may then enter the water system and vacuum out the sediment.  Everything that is loose is removed, allowing the chlorine or other treatment chemicals entering the tank to effectively do its job. This is a much more effective method than the traditional buckets and shovels.  We are able to remove ALL loose sediment without scraping shovels on painted surfaces.  In addition thereIs minimum water loss with our method, you do not need to DRAIN YOUR TANKS.         Call today to learn how we can save you water, time and money while helping you maintain the healthiest water system possible.

Why is it important to clean potable water tanks?

Cleaning these tanks and towers is important and often overlooked.  The photo below is from a July 2007 cleaning of a potable water storage tank.  This is public drinking water that goes straight to the tap.   With all of the other problems water utility directors face day to day thinking about having the floor of their storage tanks cleaned is often overlooked.  In addition in the past it has been a major disruption to water service.  The tanks would normally need to be taken out of service drained and then cleaned.  Buckets and shovels have often been the primary tools. Today, potable water dive crews can enter the water system wearing a dry suit that keeps the diver in his own environment away from the water.  They are able to vacuum the floor of the tank clean removing sediment that may contain or become a future breeding ground for harmful bacteria.  See www.ronperrin.com for more information.

How they do it:

Divers wear dry suits so no part of the man is in contact with the water in the system.  They are then washed down with a chlorin solution to be in compliance with State and AWWA regulations. Below a diver prepares to enter the water storage tank.
