About the Water Data Interpreter Website

Water Data Interpreter - Image of Water Tank This program will help you interpret the results of a routine domestic water analysis, performed by a certified drinking water analysis laboratory. The routine domestic water analysis tests for characteristics that could affect health and uses of water. Use your report to find the levels that correspond with the contaminants listed.

The results in the report you get back from the lab will show numbers in different units. In the drop down menu beside each contaminant, choose the unit appropriate for your number. Note: 1 ug/L or microgram per liter represents 1 part per billion (ppb). 1 mg/L or milligram per liter is equivalent to parts per million (ppm). 1 ug/ml or microgram per milliliter is equivalent to parts per million (ppm).

Southwest States and Pacific Islands Regional Water Program

The Southwest States and Pacific Islands Regional Water Program, one component of the CSREES National Water Program, seeks to ensure the integration of water quality efforts within the jurisdiction of each of the ten regions established by the U.S. Environmental Protection Agency (EPA). The Program is designed to make research, education, and extension resources of the university system more accessible to Federal, State, and local water quality improvement efforts, thus enhancing opportunities for agricultural producers and agriculturally impacted communities to adopt voluntary approaches for the improvement of water quality.

The Region is based on the Environmental Protection Agency, Region IX area: Arizona, California, Hawaii, Nevada, American Samoa, Guam, Republic of the Marshal Islands, Federated States of Micronesia, Commonwealth of the Northern Marianas, Republic of Palau and the Navajo Nation. The leadership team for the Program consists of the Extension Water Quality Coordinators identified at each state, island, and tribal Land Grant Institution.
