Technical Services
Illinois River, Josephine and Curry County
Every groundwater conclusion we reach is grounded in direct investigation and rigorous analysis.
Our services span the full technical spectrum, from field characterization and streamflow monitoring through contamination assessment, MAR feasibility, water right evaluation, and decision support modeling. We work exclusively in Oregon, bringing deep experience across the state’s diverse geologic settings and regulatory environment to investigations ranging from single domestic wells to basin-scale water supply planning.

Oregon regulatory context
Oregon Water Law and Regulatory Framework
Oregon’s water law is among the most complex in the West. We understand OWRD’s allocation rules, critical groundwater area designations, exempt well limitations, and the intersection of surface water curtailment with groundwater use. We build that understanding into every technical recommendation from day one.
- OWRD permitting and water right application support
- Critical groundwater area rule interpretation and compliance
- Exempt well limitation and groundwater allocation analysis
- Surface water curtailment intersection with groundwater use
- Instream flow rule and minimum perennial streamflow requirements
- Groundwater-dependent ecosystem identification
- DEQ coordination for contamination and water quality matters
- Oregon ASR permit application and operational reporting
