Lead Result Question from PR

Posted on April 17, 2017 at 10:20 AM by Parris Crooks

Below is a question from Pinedale Roundup and the Town's response.

Just a quick clarification on the recent lead-testing results.  I know the statement says 143 signed up, which was reiterated last night. However, I have a quote from the Feb. 27 council meeting in which you say that "about 250 (people) signed up for that."  I've also received other reports that put the number at over 200 as well.  So, I 'm wondering if the recent results are a partial list and we're waiting on more, or if that's the extent of the town's testing.  It seems a difference of 100 or so is not insignificant.

We had approximately 225 sign-ups for the free lead tests.  We have tested and received results for 143 properties.  Another 20 or so properties are seasonal residences and will be tested in the early summer.  That leaves approximately 60 properties that signed up for the lead test but never scheduled one.  We made multiple efforts to contact these property owners via email and phone calls.  The majority of the properties that did not schedule a test were rental properties. The rental manager signed up for the tests but left it up to the renters to schedule the test.

Lead Test Information Release

Posted on April 5, 2017 at 4:59 PM by Parris Crooks

The Town of Pinedale recently offered free lead testing to all of our water customers. We had 143 people sign up to have their buildings tested for lead in the water. The results are shown below. It is important to point out, the town water is lead free. Houses testing positive have a lead source within the private water system that the town does not own or control.

The Town of Pinedale has received the results of the 143 lead tests conducted over the last several weeks. Of the 143 samples, 78 of the samples (55%) did not detect any lead. 48 results (33%) had lead below the EPA action level of 0.015 mg/L. 17 samples (12%) had a lead level above the EPA action level of 0.015 mg/L. The results above the action limit may be slightly higher but fairly consistent with past testing over the years.

What should you do?
Every building is unique. However, we have found the lead source is most likely, but not limited to a fixture or an old brass fitting(s) within your water system. The town recommends that you follow the EPA recommendations for buildings containing lead. You can find them on their web site https://www.epa.gov/ground-water-and-drinking-water/basic-information-about-lead-drinking-water. The town highly recommends that you hire a plumber and lab to conduct further testing so you can find and eliminate the sources of lead. In the meantime time, install a point of use lead filter for your drinking water. The town also recommends that you call your doctor to see if he or she recommends those drinking from a building with high lead levels be tested for lead. The EPA estimates that drinking water can make up 20 percent or more of a person’s total exposure to lead. There are many other potential sources of lead in the environment, including soil, paint, and even some toys. For more information on lead exposure in general, please visit www.epa.gov/lead.

What is the town doing?
The Town is and has always provided water that has been treated to make it less corrosive. We have hired an engineering firm that is working with the EPA and DEQ to design a system that should be more effective than the sodium silicate system we are currently using. We are waiting for final EPA approval to implement the design changes to our treatment process. These changes will not fix the problem. At best they will lower lead levels in some buildings a small amount. To eliminate lead in your water you must remove the source.

If you have any questions please call the Town at (307) 367-4136 and talk to a water operator.

Water Testing Questions Answered

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.

    "Based on the minimal info we have regarding the school testing, the most plausible explanation for the decrease with the school test results is the increase in pH of the incoming 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?
