ANSI/NSF 61-certified PVC for water delivery is not Benzene resistant

Ooops so yet another good reason to Make Your Own Water with an Atmospheric Water Generator.

In my previous blog, I posted a rather exhausting list of boil water advisories.
How prevalent are water main breaks?

Visit here….

“Every day, 850 water main breaks occur in North America at a total annual repair cost of over $3 billion. This doesn’t include the high costs of emergency equipment, depleted water supply, traffic disruptions, and lost work time. 
 All told, leaking pipes lose some 2.6 trillion gallons of drinking water every year, or 17% of all water pumped in the United States. This represents $4.1 billion in wasted electricity annually”.


Note that the WaterMainBreakClock website is the love child of the PVC Association. I’m betting that PVC is no better than HDPE when it comes to the Houdini of hydrocarbons…BENZENE.

The National Sanitation Foundation (NSF) Standard 14 & 61 has listings for potable water applications, but do they stand up to the Frack Attack?  Nope!

The site,,weighs the pros/cons of PVC vs HDPE and attempts to answer the question (I bold faced for emphasis), “Is the pipe material resistant to permeation in contaminated soils/groundwater?” and here is the answer from the PVC spokesperson…. “It is far better and more sustainable to use pipes that are inherently well suited for their operating environments, including exposures to contaminated soils. This has contributed greatly to PVC pipes’ rise to become the most-installed product for new water and wastewater systems. Utilities have acquired a true appreciation of PVC pipes’ low-maintenance, corrosion-free performance and resistance to permeation by hydrocarbons at levels normally encountered“.

Normally encountered? Crude oil pipeline spills and frack brine and frack chemical spills are not normal (neither is fracking in residential neighborhoods) and so there we should have an immediate sense of dread since our Arlington water director responded to me “To date we have only used HDPE in residential replacement projects none of which are in a high risk zone. However,  PVC pipe has been a standard pipe material for small diameter water and sewer lines in Arlington and many other communities for many years”.  

ol’Benzene worries me and in my research I repeatedly found statements such as “The listing that follows does not address chemical combinations”. This link shows a numbering system for individual chemicals:

1 – High Resistance

2 – Limited Resistance

3 – No Resistance

Benzene has limited resistance at 104 degrees fahrenheit for PVDF. Polyvinylidene fluoride is a more expensive polyvinyl by a factor of 8 than PVC and so don’t look for your city to man up to a more expensive piping.

For PVC,  Benzene has no resistance.

As for HDPE, Benzene has limited resistance (over an hour?) at 68 degrees fahrenheit.

Previously I blogged about Benzene in soil can put your health at risk if it gets into your drinking water and this link, has a letter from the Senior Manager of Standards at the American Water Works Association responding to me saying (I boldfaced for emphasis)…. “AWWA does have several standards on HDPE pipe, and we do include information in those standards that alerts users that should be cautious where hydrocarbon contamination may be an issue.  The following note is included in those standards:

Sec. 4.1 Permeation
               The selection of materials is critical for water service and distribution piping in locations where the pipe will be exposed to significant concentrations of pollutants comprised of low molecular weight petroleum products or organic solvents or their vapors. Research has documented that pipe materials such as polyethylene, polybutylene, polyvinyl chloride, and asbestos cement, and elastomers used in jointing gaskets and packing glands, are subject to permeation by lower molecular weight organic solvents or petroleum products. If a water pipe must pass through a contaminated area or an area subject to contamination, consult with pipe manufacturers regarding permeation of pipe walls, jointing materials, etc., before selecting materials for use in that area”.
Feeling better living near industrialization and frack sites?  Solution: Make Your Own Water, pipe it to your house using above ground piping protecting it from the sun and take control of your own water quality.
Merry Christmas…drink safe ya’ll.

About Kim Triolo Feil

Since TX Statute 253.005 forbids drilling in heavily settled municipalities, I unsuccessfully ran for City Council Seat to try to enforce this. Since Urban Drilling, our drinking water has almost tripled for TTHM's. Before moving to Arlington in 1990, I lived in Norco’s “cancer alley”, a refinery town. It was only after Urban Drilling in Arlington did I start having health effects. After our drill site was established closest to my home, the chronic nosebleeds started. I know there are more canaries here in Arlington having reactions to our industrialized airshed (we have 55-60 padsites of gas wells). Come forward and report to me those having health issues especially if you live to the north/northwest of a drill site so I can map your health effects on this blog.
