I would like ask what is gage capability of the measurement instrument or the methodology? In addition, these chemical are used by other cities for their streets, how are their results?

I would like to see the city look for better water sources than well water. Well water is the primary reason we have such hard water in Pleasanton. The city and/or Zone 7 should be looking into tying into a better water source such as SFPUC or EBMUD.

Hetch Hetchy water source is available to Pleasanton.
The city needs to negotiate a deal for it.
Hetch Hetchy serves Castlewood, Sunol and points south..

For once I agree with Michael. There is a pipeline connection between the Hetch Hetchy distribution system and the Pleasanton water retailing distribution system. One closed valve keeps the supply from us. It's a political solution that our city has been unwilling to take. Unfortunately, Zone 7 has statutory authority over our water supply no matter how much pollution they deliver. It all boils down to unlimited growth in the Tri Valley and who can provide the (polluted) water supply to serve it.

If you want to understand PFOAs and just how very dangerous they are, see the movie Dark Waters currently playing at the Vine Cinema in Livermore as of Dec. 21 which details the decade long lawsuit against DuPont regarding teflon and PFAS in ground water. The levels in "Mocho 1" in Pleasanton are above the action level (and yes, it is very dangerous) and three wells have levels that are above the notification levels. This is terrible news for our city's drinking water, and there is no easy way to clean this up.
Additionally here is a Reuters report that talks about how unsafe the current notification levels are:
