regional water authority, lead management from "waterlines"

"The water that leaves RWA's treatment plants...has no lead in it. But as water sits in plumbing systems small amounts of lead from lead pipes or lead solder...can dissolve in the water".  From "waterlines" included in our last bill from RWA:  https://www.rwater.com/media/3814/waterlines-spring-2019.pdf   
Information is included about how to test your water and what to do about it if it has high lead levels.  If you are concerned and don't want to get the test done you could just follow the guidelines in the article as a precaution.
