I have inspected (for natural resource protection, not air quality) CIPP projects. I can assure you that anywhere within 100 yards of this process you can get knocked over by the sharp aromatic smell of these chemicals. The workers I observed used very little protection outside of gloves and the occasional dust mask. Being around it for any length of time gives me headaches. Nasty stuff, but it’s a heck of a lot easier than digging up old pipes.
Awesome reporting and rigorous methodology – however…. I would love to see two versions of your reporting – Light – a graphic instead of a picture in this case representing an aging leaking pipe, then the liner then some angry faces representing the chemicals with question marks (safe???) basically the same article with 1/10 of the text that gets the key points across. Then a link to the full article complete with supporting information. This could reach a much wider audience. Thanks for all your efforts.
This process is being done in my neighborhood un Salem, VA . In our early 1950s house, drains were installed in the basement floor, tied into the sewer line, so many homes have filled up with these gases. Several residents with compromised immune systems have had long dormant illnesses and symptoms return with a vengeance since being, in most cases, unknowingly exposed. Liner companies, beuracrats who hire them, as well as first responders should be aware of the adverse effects of these dangerous gases. For instance, a 3 gas meter wont detect these. As we, in our, neighborhood, are now aware. So even fire and EMTs are in danger. There is great need for this process to be regulated. No agency, including VA Dept of Health, can do anything to protect us. DEQ says they cannot investigate due to the temporary nature of the work. Interestingly, in meetings with City officials and the consulting engineer, we were told that DEQ had granted a $1M interest free loan to fund this CIPP project. Yes. Follow the money. And as far as being temporary work, it is contractural work, permanently installed. Another interesting incident that occurred in my home after CIPP was performed one street over is that I smelled and tasted Styrene in my water, blisters developed in my mouth. I have now found the correct test, performed by an independent lab, which, done 6 months after the contamination, was negative. I am ready to retest if it happens again, in a timely manner.
This is a quick fix that will become a disaster watch and see!
The concept is good but like to many examples one can find many companies just want to get a proceeds in the field and deal with issues later. I agree with a prior commenter. Ok for sewers but not drinking water without much more research by non industry funded scientists.
I know this industry and these contractor groups intmately, having invented some and marketed many of their components. They are just protesting to protect profits at the expense of proper safety and environment. Follow the money. Believe the Purdue people. And,GOD don’t line potable water pipes with this stuff.
Thank you for this important work–unflinching, rigorous reporting.
