Why are we hearing about PFAS now if they've been around for decades?

PFAS compounds are difficult to detect. They exist in most products at extremely minuscule levels. It’s only recently that laboratory testing technology could detect them at the levels being discussed.
 
Technological advances now allow us to detect concentrations in the parts-per-trillion (ppt) range. For perspective, a part per trillion is one drop of water in 20 Olympic-sized pools. The health advisory limits, however, are below what can be currently detected. 

The scientific understanding and regulatory response to these compounds is uncertain but rapidly evolving. This includes potential public health implications.

Castle Rock Water is closely monitoring the new EPA drinking water health advisories for PFAS chemicals and will be working with the state to protect public health. Castle Rock Water uses the latest and best technology available to monitor and safeguard your drinking water.
