Understanding the Umatilla Basin Groundwater Crisis
The Lower Umatilla Basin Groundwater Management Area (LUBGWMA) spans approximately 550 square miles across northern Morrow and northwestern Umatilla counties in Oregon. This region has been grappling with high levels of nitrate contamination in its groundwater for decades, prompting the Oregon Department of Environmental Quality to designate it as a groundwater management area back in 1990.
Fast forward to 2022, and the situation had escalated to such an extent that Morrow County declared a local state of emergency due to dangerously high nitrate levels in the groundwater. This declaration underscored the urgency of addressing this long-standing environmental and public health issue.
The Drinking Water Roadmap Project: A Beacon of Hope
“The Drinking Water Roadmap Project, launched in 2024, aims to solve groundwater issues for domestic well users in Oregon.”
In response to this crisis, the Drinking Water Roadmap Project was launched in 2024. This collaborative initiative between Morrow and Umatilla counties aims to find long-term drinking water solutions for domestic well users affected by dangerous levels of nitrates in the LUBGWMA. Funded through a research grant from the U.S. Environmental Protection Agency, this project represents a significant step towards addressing the groundwater contamination issue that has plagued the region for years.
The Four Stages of the Roadmap Project
- Stage 1 (Spring 2024): Development of work plans, data gathering, preliminary outreach, and baseline assessments of the study area.
- Stage 2: Evaluation of the feasibility of connecting residents with contaminated wells to public water systems.
- Stage 3: Exploration of alternative solutions for areas where public water system connections are not feasible.
- Stage 4: Public discussion of potential paths forward for the drinking water options in the studied areas.
As we progress through these stages, it’s crucial to understand the scope of the problem and the challenges we face in implementing effective solutions.
The Scope of Nitrate Pollution in the Lower Umatilla Basin
The extent of nitrate pollution in the LUBGWMA is alarming. Out of approximately 3,000 wells in the project area, just under 2,000 have been tested. The results are concerning:
- About 29% of the tested wells have been found to have dangerous levels of nitrates
- These wells are deemed unsafe for drinking or cooking
- Water with nitrate levels above 10 milligrams per liter is considered unsafe to drink
These statistics highlight the urgent need for comprehensive testing and remediation efforts. However, one of the significant challenges facing the project is encouraging the remaining 1,000 well users to participate in free water testing.
Sources of Nitrate Contamination
Understanding the sources of nitrate pollution is crucial for developing effective long-term solutions. The main contributors to nitrate contamination in the LUBGWMA include:
- Agricultural fertilizers
- Animal manure used on nearby farms
- Sewage and septic waste
These sources highlight the complex interplay between agricultural practices, waste management, and groundwater quality. Addressing these issues requires a multifaceted approach that balances the needs of agriculture with environmental protection and public health.
Health Risks Associated with Nitrate Pollution
The health implications of consuming water with high nitrate levels are severe and can lead to various health problems, especially when consumed over long periods. Some of the potential health risks include:
- Blue baby syndrome (methemoglobinemia) in infants
- Increased risk of certain types of cancer
- Thyroid dysfunction
- Reproductive issues
Given these risks, it’s crucial that we prioritize finding safe drinking water solutions for affected residents.
Current Mitigation Efforts and Challenges
In response to the immediate needs of affected residents, several measures have been implemented:
