Where do I collect samples required under the Phase II/V Rules?

Excluding asbestos, all samples required under the Phase II/V Rules are collected from each point-of-entry to the distribution system, commonly referred to as a POE. The POE is a location after which raw water has been treated but before treated water has entered the distribution system. Each POE sample location should be marked by a metal tag stamped with an eight-digit identification number. The sample paperwork you receive from the lab will always specify the collection site.
