# 9.5 Verification of drinking water quality Verification of drinking water quality provides an assessment of the quality of drinking water being supplied to consumers. It incorporates monitoring drinking water quality in the distribution system and assessing consumer satisfaction. Verification of drinking water quality provides an important link back to the operation of the water supply system and additional assurance that the preventive measures and treatment barriers in the water supply system have worked, and are working, to supply safe drinking water. This information helps in assessing long-term system performance and identifying any trends or problems within the water supply system that may have gone unrecognised, and it provides confidence to consumers and regulators regarding the quality of water supplied. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
