Interpreting Drinking Water Quality Analysis What Do the Numbers Mean?
Drinking water test results may be difficult to understand. This booklet clarifies test results by defining terms and standards used in the analysis of both public and nonpublic water supplies (home wells). Created primarily for homeowners (but suitable for health departments, environmental organizations, and other interested parties), the book also describes what tests are needed, where to have water tested, and how to treat the water when problems arise.

Community Involvement in Drinking Water Source Assessments
By working with their state’s source water protection program, community groups can help identify potential threats to their drinking water. They can also help local officials develop and implement a plan of action to prevent water quality problems. This fact sheet explains the four steps of source water assessments and how communities can participate in the process. It also describes how communities can use assessment information to protect local water sources.

Preventive Maintenance Tasks for Tribal Drinking Water Systems
Created like an old-fashioned recipe box, this handy toolkit helps document activities related to maintaining drinking water systems. A guide book outlines daily, weekly, and monthly tasks, and 3x5 cards hold the corresponding data. The kit allows changes and additions depending on a system’s treatment method and water supply. Additional sources information and contacts are provided. Note: the kit does not take the place of a complete operation and maintenance manual.
