A Roadmap for Safe Drinking Water
Morrow and Umatilla Counties are facing a decades-long problem with elevated levels of nitrate in
groundwater in northern parts of the two counties. This affects thousands of rural residents who rely on wells
for drinking water. The Oregon Department of Environmental Quality (EPA) designated the affected region as
the Lower Umatilla Basin Groundwater Management Area (LUBGWMA) when problems were first recognized
in 1990.
Through a joint effort of Morrow and Umatilla Counties, the Drinking Water Roadmap Project was launched in
2024 to study safe and reliable drinking water solutions for domestic well users. The Roadmap Project is
funded through a research grant from the EPA and is being managed by the Morrow County Planning
Director (“Principal Investigator” under the EPA grant) with a consultant team led by GSI Water Solutions, Inc.
to conduct the work.

Why It Matters
Find Lasting Solutions
The overall goal for this project is to find potential options for long-term solutions to provide safe and sustainable drinking water to well users who may be affected by high nitrate levels in groundwater within the project area.
Timeline: Through 2026
The Drinking Water Roadmap is being conducted in four stages over 2 ½ years. Stage 1 began in Spring 2024 and focused on developing workplans, initial water sampling and data gathering, preliminary outreach to well owners, and conducting baseline assessments of the study area. The final stage will culminate in summer 2026 with completion of a “Drinking Water Action Plan” that will present recommendation for implementing long-term solutions.
