Hydrogeologist Jobs in Washington: Frequently Asked Questions
How do you become a hydrogeologist in Washington?
Washington State licenses hydrogeologists through the Washington State Department of Licensing under the Licensed Hydrogeologist designation, which requires a qualifying degree in hydrogeology or a related geoscience, documented experience, and passing the American Institute of Hydrology exam or an equivalent. Many employers also value or require a Professional Geologist license through the same department. A bachelor's degree in geology or hydrogeology is the standard entry point, and a master's degree strengthens competitiveness for project-level roles.
How much do hydrogeologists make in Washington?
Hydrogeologists in Washington earn a median of about $105,600 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $80,450 for the lowest 10% to over $194,900 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire hydrogeologists in Washington?
Employers hiring hydrogeologists in Washington right now include State of Washington, WSP, and GSI Environmental, based on current listings on Migrate Mate as of August 2026. Washington's environmental consulting sector and state agency programs generate much of the sustained demand, particularly around remediation, water resource permitting, and infrastructure projects.
Which Washington cities have the most hydrogeologist jobs?
Union Gap, Washington State, and Lacey are the Washington cities with the most hydrogeologist openings. Seattle anchors the market through its concentration of environmental consulting firms and federal contractors, while Olympia draws demand from state agency headquarters including the Department of Ecology, and Spokane serves as the hub for eastern Washington water resource and mining-adjacent projects.
Are there remote hydrogeologist jobs in Washington?
Yes, but they're rare. Hydrogeology is fundamentally a field-intensive discipline, and most Washington roles require site visits, well sampling, or in-person regulatory meetings. About 71% of hydrogeologist openings tied to Washington are remote or hybrid as of August 2026, and the positions most likely to offer flexibility are data analysis, groundwater modeling, and report-writing assignments within larger project teams.
How can I get hired as a hydrogeologist in Washington with little or no experience?
The most realistic entry path is applying for field technician or environmental scientist associate roles at Washington's environmental consulting firms, where hands-on site work builds the documented experience hours required for state licensure. Firms like Parametrix and RH2 Engineering regularly bring on graduates for support-level positions. Pursuing the Licensed Hydrogeologist credential early, even before full qualification, signals intent to employers. Adjacent starting points include water quality technician roles at county public health departments or monitoring positions with the Washington State Department of Ecology.
Where can I find and apply to hydrogeologist jobs in Washington?
You can find and apply to hydrogeologist jobs in Washington on Migrate Mate, which lists current Washington openings. Search the available roles, find the ones that match your background and target location, and apply directly to the employers posting them.
