Lead Tap Sampling Approaches: What Do They Tell You

Schock, M., J. Tully, AND K. Cahalan. Lead Tap Sampling Approaches: What Do They Tell You. Ohio Secton AWWA, Cincinnati, Ohio, September 14 - 16, 2016.
Impact/Purpose:
Describe sampling protocols useful for different purposes, to enlighten a utility and local consultants about non-regulatory sampling and how it can help identify and resolve lead and copper issues.
Description:
There is no single, universally applicable sampling approach for lead in drinking water. The appropriate type of sampling is dictated by the question being asked. There is no reason when a customer asks to have their home water tested to see if it's "safe" that they should be given an LCR sampling kit. It doesn't answer the customer's question, as that sampling protocol was not intended to estimate either average or peak exposure probability. This talk will review many kinds of sampling protocols that have been used in the US and other countries for many purposes: regulatory compliance monitoring, diagnosing lead occurrence in plumbing systems; trying to identify the presence of lead service lines; estimating corrosion control effectiveness; and estimating household exposure and risk.
