Environmental Engineer Jobs in Tucson, AZ
Tucson has been doing groundwater remediation longer and harder than almost any city in the country, and that history is the environmental engineering job market here. The Tucson International Airport Area went on the EPA Superfund National Priorities List in 1982 after TCE shut down eleven city wells. Since 1994 the Tucson Airport Remediation Project has cleaned 51.3 billion gallons of groundwater and pulled out 5,625 pounds of TCE. Now PFAS has restarted the whole effort: ADEQ committed $25 million to PFAS treatment at TARP, an advanced oxidation pretreatment facility broke ground in January 2025 with completion expected around August 2026, and the Northwest Wellhead Treatment Facility is in development to bring three wells back into production. That is a decades-long pipeline of work, not a project.

Top Tucson Employers Hiring Environmental Engineers
Environmental engineering demand in Tucson comes from water utilities, the copper mines, consulting firms and the agencies that regulate both.
- Tucson Water - TARP and the advanced oxidation plant, PFAS ion exchange treatment, the CAVSARP and SAVSARP recharge basins, and the One Water 2100 long-range planning framework.
- Pima County - the Regional Wastewater Reclamation Department plus Environmental Quality, covering treatment plants, biosolids, air quality permitting and stormwater.
- Freeport-McMoRan - the Sierrita Voluntary Remediation Program, tailings and water management, plus a Tucson technology center staffed with engineers working on environmental solutions for mining.
- WestLand Resources - a Tucson-based engineering and environmental consultancy doing heavy mine-support work, including at Sierrita.
- Civil & Environmental Consultants - opened its Tucson office in 2023 through the acquisition of the local firm Engineering and Environmental Consultants.
- ADEQ and consulting firms - the Arizona Department of Environmental Quality plus Carollo, AECOM, Tetra Tech and SRK Consulting all staff Southern Arizona water and remediation work.
Environmental Engineer Salaries in Tucson
Environmental engineering pay in Tucson runs close to civil engineering, with mining and private consulting above the public agencies.
- Entry level (0-3 years, EIT): roughly $62,000 to $80,000 per year.
- Experienced (4-8 years, licensed PE): roughly $85,000 to $115,000 per year.
- Senior or program lead (8+ years): roughly $115,000 to $155,000 per year, with mining environmental leads at the top of the local range.
These are estimates that vary by employer and experience. Tucson Water, Pima County and ADEQ pay less in cash but include Arizona State Retirement System participation and unusually stable project pipelines; consulting pays more and bills your hours.
How to Become an Environmental Engineer in Tucson
Most Tucson environmental engineers come out of civil, environmental or chemical engineering, and the University of Arizona is the local pipeline through its Department of Civil and Architectural Engineering and Mechanics and its Department of Environmental Science.
- Degree: ABET-accredited BS in environmental, civil or chemical engineering from UA, or Pima Community College transfer coursework plus the AGEC-S into UA.
- FE exam: apply to the Arizona State Board of Technical Registration, pass the NCEES FE exam, register as an Engineer in Training.
- PE license: four years of progressive experience under a licensed PE, then the NCEES PE exam. Required for stamped water, wastewater and treatment design.
- Regulatory knowledge: the alphabet that runs this market - CERCLA, RCRA, the Clean Water Act, ADEQ's Water Quality Assurance Revolving Fund, EPA PFAS maximum contaminant levels, APP and AZPDES permitting.
- Add-ons: 40-hour HAZWOPER for site work, and MSHA training for mine-site assignments.
A state license is required for design work that gets stamped and submitted, and the Arizona Board of Technical Registration issues it. Compliance, permitting and remediation roles often do not require a PE, though it raises your ceiling in every one of them.
What the Job Involves
The work moves between three places. At a desk, you are running treatment models, writing permit applications and assembling remedial investigation reports for ADEQ or EPA. In the field, you are sampling monitoring wells around the central wellfield, walking a tailings facility at Sierrita, or standing in a treatment plant during a startup. In a conference room, you are explaining to a neighborhood or a county board what the numbers actually mean, which in Tucson is a real part of the job because residents here have been living with contaminated groundwater since the early 1980s and they follow it closely.
Skills Employers Look For
- Water and wastewater treatment process knowledge - ion exchange, granular activated carbon, advanced oxidation - which is precisely what Tucson's PFAS work runs on.
- Groundwater modeling and hydrogeology; MODFLOW and plume delineation experience.
- Permitting fluency: ADEQ Aquifer Protection Permits, AZPDES, air quality permits through Pima County.
- CERCLA and RCRA site work, since the Tucson airport area is a live Superfund site.
- EIT early, PE by mid-career, plus HAZWOPER and MSHA for field and mine work.
- Plain-language public communication, and bilingual Spanish for south-side community outreach.
Career Path and Advancement
The Tucson path runs staff engineer to project engineer to project manager, with the PE license around year four to six as the hinge. Where it goes next is a local choice: the utility and county track leads to senior engineer and division management at Tucson Water or Pima County RWRD, with a pension attached. Consulting leads to principal and business development, with better pay and worse hours. Mining is the third and best-paying branch, where Sierrita reclamation and water management experience travels across Freeport-McMoRan's whole Arizona portfolio. Water resources and PFAS treatment are the two specialties with the most durable demand in this region, and both transfer well across the Southwest.

Frequently Asked Questions
Do you need a PE license to be an environmental engineer in Tucson?
For design work, yes. Treatment plant, pipeline and remediation designs submitted to ADEQ, Tucson Water or Pima County need a PE seal from an engineer licensed by the Arizona State Board of Technical Registration. Compliance, permitting, sampling and remediation project roles often do not require it, and plenty of Tucson environmental engineers work for years as EITs. The license still governs how far you advance in this field locally.
Why is there so much environmental engineering work in Tucson?
Groundwater contamination and a desert water supply. The Tucson International Airport Area has been an EPA Superfund site since 1982 after TCE closed eleven city wells, and TARP has been treating that plume since 1994. PFAS from firefighting foam at Davis-Monthan Air Force Base, the Arizona Air National Guard base and the airport has since taken more wells offline and triggered a new wave of treatment projects. Layer on copper mine reclamation at Sierrita and CAP recharge operations, and the workload is structural.
Which Tucson employers hire environmental engineers?
Tucson Water and Pima County Regional Wastewater Reclamation are the two largest public employers, with ADEQ regulating alongside them. Freeport-McMoRan hires for Sierrita remediation, tailings and water management plus its Tucson technology center. On the consulting side, WestLand Resources is the significant Tucson-based firm, and Civil & Environmental Consultants, Carollo, AECOM, Tetra Tech and SRK Consulting all staff Southern Arizona work.
What is PFAS and why does it matter for Tucson engineering jobs?
PFAS are persistent synthetic compounds that came into Tucson's groundwater largely through firefighting foam at Davis-Monthan, the Air National Guard base and Tucson International Airport. Tucson Water voluntarily pulls any well showing detectable PFOA or PFOS, which is stricter than the EPA limit. That policy plus $25 million in ADEQ funding, the ion exchange system at TARP, the advanced oxidation pretreatment facility due around August 2026 and the Northwest Wellhead Treatment Facility add up to years of engineering work with funding already attached.
Can environmental engineers work at the mines near Tucson?
Yes, and it is often the best-paying option in this field locally. Freeport-McMoRan's Sierrita complex 20 miles southwest runs a Voluntary Remediation Program and needs engineers for tailings, water management, closure and permitting. Hudbay's Copper World project is ramping up nearby, and Tucson consultancies such as WestLand Resources and SRK Consulting staff much of the technical work. Expect to add MSHA training and real field time.
