Water Testing Questions Answered

Posted to Lead Information by Parris Crooks



Looking at lead testing data trends since 2002, the results of the EPA required lead testing, from when soda ash was used in comparison to when sodium silicate was used our trends show minimal difference.  The pH range required by the EPA in the past has always been lower. When we went off soda ash and back on to sodium silicate the EPA required a much higher dose of sodium silicate than the town had ever used in the past. We did some jar testing and found that this dose would have a dramatic impact on our pH. The EPA acknowledged this and increased our maximum pH to a higher level so we could continue dosing the sodium silicate at EPA's desired level. The end result is that our requirements have been changed and what was done in the past and what is being done now is not comparable because of the change in dosing and resulting pH.

It is very important to understand and take into account the change in environment at the EPA. Pinedale has a new rules manager and the emphasis on lead has dramatically changed. Pinedale water is unique and our system has been under very close scrutiny because there are no other systems quite like ours to compare with. Our system has been reviewed by the EPA research and development department and we are currently conducting further testing to optimize our system and provide our citizens with the best water.

    So how does this relate to the water treatment previously done when soda ash was the primary CCT? Were the appropriate pH levels not being adequately achieved? If not, why not. And if so, why would the levels at the district now drop with sodium silicate but not the previous soda ash treatment?

Bleeding Water Lines

Posted to Town of Pinedale by Parris Crooks

Hi, this is Bob Jones with the Town of Pinedale. I’d like to take a minute to remind you about a few things that may be unique to cold weather operations in Pinedale.

As most of you know, we have several water lines freeze every year. Our prolonged cold temperatures cause the ground to freeze down below most of the water lines in town. If a water line is in frozen ground, it will freeze, and it is very difficult and expensive to thaw the line.  To avoid freezing, the water in the lines must be moving. Over the past several years the Town of Pinedale has redesigned and replaced almost all of the water lines with a new looped system that keeps the water in constant motion so the mains won’t freeze. The water line from the town main to your building is your responsibility and it is not looped. This means it will freeze if you don’t keep water moving through it at all times when the ground is frozen. The best way to do this is to have a small valve installed at the end of your water system that can be turned on in the fall before the ground freezes and turned off in late spring when the ground thaws. If you don’t have such a valve you can open a faucet and let water run. Just make sure someone doesn’t accidentally turn it off. That’s why we recommend an isolated dedicated valve that won’t be accidentally turned off. The town has given everyone a 40,000 gallon monthly water allowance in your water bill. So you can afford to bleed or run the required water so you don’t freeze up. One last thing regarding bleeding. Don’t be fooled by a few days or weeks of warm weather. The ground down deep is still frozen and will freeze your water service in short order.

I know I don’t need to tell you but we have had a lot of snow this year and the guys in public works have been working hard to keep our roads passable under difficult conditions. We have limited places to put the snow and it takes a lot of maneuvering to accomplish our job. So, please be careful as you approach a piece of equipment on the road or in a parking lot. We try, but it is hard   to see to the sides and behind us. I would hate to see someone get hurt over trying to save a minute or two. By the way, I tell the guys their number one often. You probably don’t need to give them the number one sign when there is a small delay. We are doing our best.

Thanks and Have a great day.
