New - Sampling Plan Guidance


The Compliance and Regulatory Committee of the Drinking Water Advisory Workgroup has worked diligently over the past year to develop guidance for water systems regarding how to best manage sample plans for the distribution system. The resulting Sampling Plan Guidance document provides an overview of regulatory requirements for distribution system sampling and best practices to ensure that water quality in the distribution system is well-monitored, so public water systems can be confident that they are providing water of the highest quality possible to customers.

This document can be found at the Division of Water website:, in the ‘Requirements, Templates, and Guidance’ section. This webpage also has many other resources useful for drinking water operators, including templates and guidance on various rules of the Safe Drinking Water Act.
