Pleasanton council to review report on PFAS levels in local water supply

Original post made on Nov 5, 2019

The City Council is set to discuss a report from city staff about the response plan to address levels of human-made chemicals in the so-called "per- and polyfluoroalkyl substances (PFAS) family" found in the local water supply.

Questioning if it is advisable to drink and cook with bottled water considering the current levels of these substances in our water. Also are most filtering systems as well as those provided in refrigerator water dispensers capable of filtering out these chemicals. Would appreciate anyone’s information on this. Thanks.

I have been drinking Pleasantons water for a long time. So what exactly constitutes a "notification level"? Have I just been notified that I have consumed too much of these toxins? And what mitigation efforts have other water providers taken to remove them?

From the article it seems unclear how big of a health threat the current situation is. Usually "notification levels" are set well below the levels of actual health and safety concerns. Don't know what kind of refrigerator filter you're talking about, but if it's an activated carbon filter then those are effective at capturing PFAS chemicals, although you need to make sure that the filter isn't too old because it will lose effectiveness over time as it gets saturated after capturing more and more chemicals.

I think that the best water filtration systems available for household use are reverse osmosis water filters. We have a 5-stage reverse osmosis (RO) system that sits in the cabinet under our kitchen sink. The first three stages filter out small particles and the 4th stage consists of a "membrane filter" which has tiny pores that are so small that virtually nothing bigger than a water molecule can pass through it. Household RO systems go for around $200-$300. You can probably find one at Home Depot or Lowes or Amazon, etc.

Patty, Hotslide, and Wombat, visit Zone 7 website for details about notification levels and what it means for residents drinking the water.

Short answer, no, we have not been subjected to dangerous toxins in our water. The notification level is currently 70 parts per trillion, equal to 1 gram in about 20 olympic size swimming pools. Pleasanton sent out a flyer recently, detailing the issue and measures that have been taken. It is important to note that only recently has technology existed to test for these compounds, and neither state nor federal standards have existed. There is no cause for panic, bottled water likely poses as much threat from materials leached from being dispensed in plastic bottles.
Our water has been and is perfectly safe to drink. The city has set up a web page dedicated to PFAS/PFOS and the state is conducting a webinar on November 15

We owe it to ourselves and our families and friends to be aware but not alarmed. Don't lose sight of the simple fact that our local and regional government leaders live here, too, and they also drink and cook with and bathe in the water just as the rest of us do. Every effort is being put forth to keep us informed of developments, and there is no scientific evidence saying our water is bad for us.

Don't miss out on the discussion!
