Environmental Geologist Jobs in Colorado: Frequently Asked Questions
How do you become a environmental geologist in Colorado?
The standard path begins with a bachelor's degree in geology or a related earth science, followed by gaining qualifying field experience under a licensed geologist. Colorado licenses geologists through the Colorado Office of Geologic Licensing and Standards, which administers the Professional Geologist credential. Most positions require or strongly prefer this state license, so candidates should plan to sit for the ASBOG Fundamentals and Practice exams as early as eligibility allows.
How much do environmental geologists make in Colorado?
Environmental geologists in Colorado earn a median of about $114,410 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $70,410 for the lowest 10% to over $210,090 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire environmental geologists in Colorado?
Employers hiring environmental geologists in Colorado right now include Onterris, Haley & Aldrich, and Burns & McDonnell, based on current listings on Migrate Mate as of August 2026. Colorado's density of federal land, active mining permits, and brownfield remediation projects keeps demand particularly consistent among engineering consulting firms and state agency contractors.
Which Colorado cities have the most environmental geologist jobs?
Denver, Loveland, and Greenwood Village account for the largest share of environmental geologist openings in Colorado. Denver anchors the market as the headquarters for major consulting firms and CDPHE operations, Fort Collins draws demand from Colorado State University research partnerships and Front Range industrial clients, and Grand Junction serves the Western Slope's active oil, gas, and mining sectors.
Are there remote environmental geologist jobs in Colorado?
Yes, but they're rare. Environmental geologist work is heavily field-dependent, so fully remote positions are uncommon. About 33% of environmental geologist openings tied to Colorado are remote or hybrid as of August 2026, and those roles typically involve data analysis, report writing, or project management rather than on-site sampling or monitoring work.
How can I get hired as a environmental geologist in Colorado with little or no experience?
The most realistic entry point is an internship or staff geologist role at a mid-size environmental consulting firm, where new graduates log supervised field hours toward Colorado Professional Geologist licensure. Large Colorado employers like Tetra Tech and Arcadis run associate-level programs for candidates without direct experience. Adjacent roles such as field technician or environmental scientist are common lateral starting points, and having completed coursework in hydrogeology or soil science alongside any field sampling experience gives candidates a clear edge.
Where can I find and apply to environmental geologist jobs in Colorado?
You can find and apply to environmental geologist jobs in Colorado on Migrate Mate, which lists current Colorado openings. Search the roles available, find the ones that match your experience and location, and apply directly to the ones that fit.
