What you earn and what it costs to get there.
Typical
$107,110
Starting out
$69,990
Senior or principal
$162,220
The national median is $107,110 a year, and the bottom tenth start near $69,990. This is a published figure for environmental engineers specifically, not a broader group. Consulting firms pay more than government, government pays more reliably, and the top of the range is people who run projects and bring in the work.
About $70,000 to $80,000
First job out of a four-year engineering degree
This is one of the few careers where a four-year degree gets you near six figures within about five years. The first jump usually comes when you pass the licensing exam and can run your own projects.
Professional Engineer
About 4 years of supervised experience after the degree
Without a license you work under someone who has one. With it, you can seal drawings and reports, take legal responsibility for a design and be the named engineer on a project. It is the clearest single step up in pay and in what you are allowed to do.
Tuition, fees, exams and kit. Not rent, food or travel
The low end is two years at a community college and then a transfer to an in state public university to finish the accredited degree, plus the fundamentals of engineering exam usually taken in your final year. The high end is all four years at the top of the in state public range, plus the professional engineer exam, the state license application and the first renewal. Out of state or private tuition can roughly double the top figure. Engineering degrees carry a lot of paid internships, so many students graduate owing less than classmates in other subjects.
Fill in the Free Application for Federal Student Aid (FAFSA) for Pell Grants and federal loans, and take the first two years at a community college if money is tight. Engineering degrees carry a lot of paid internships, so a lot of students graduate with less debt than their classmates in other subjects.
Employer-paid licensing
Most firms pay your exam fees, your study materials and often a bonus when you pass.
Government pensions
State environmental agencies, cities and water utilities hire heavily and many still offer defined pensions.
Public Service Loan Forgiveness
Federal, state and city engineering jobs qualify. Ten years of payments on an income driven plan and the remaining federal student loan balance can be forgiven.
Paid internships and co-op terms
Standard in engineering degrees, and they usually turn into the first job offer.
The exact path from high school to qualified.
Four years to a job, about eight to a full license.
High school diploma
Grades 11 and 12
Calculus, chemistry and physics. Engineering programs assume all three and admission is based on them.
Bachelor's degree
4 years
Environmental engineering, or civil engineering with an environmental focus. Make sure the program is accredited for engineering, not engineering technology.
Fundamentals of Engineering (FE) exam
Final year
Taken near graduation. Passing makes you an engineer in training, which is the first half of licensure.
Work under a licensed engineer
4 years
Usually four years of documented, supervised experience at a consulting firm, an agency or a utility.
Principles and Practice of Engineering (PE) exam and state license
After the experience
Pass the environmental discipline exam and apply to your state board. Then you can seal your own work.
Calculus
Engineering programs start at calculus. Arriving without it costs you a year.
Chemistry
More important here than in any other engineering branch. Treatment, contamination and air quality are all chemistry.
Physics
Flow, pressure and energy underpin every system you will design.
Biology
Wastewater treatment is largely a matter of keeping the right microbes alive and fed.
There is no national engineering license. Each state has its own board, and you apply to the one where you work, though the exams are the same everywhere because they are written by the National Council of Examiners for Engineering and Surveying. Getting a license in a second state later is usually straightforward. One thing to check before you enroll anywhere: your degree needs to be accredited under the engineering commission of ABET (the accreditor for engineering and technology degree programs), not the separate engineering technology commission, or some state boards will not accept it.
State universities
Nearly every state has at least one accredited environmental or civil engineering program, and in-state tuition makes it the best value.
Community college transfer
Two years of math and science at community college prices, then transfer into the engineering school. Check which credits transfer first.
Civil engineering with an environmental track
More common than a standalone environmental degree, and it keeps more career doors open.
Master's degree
Not required, but common for water treatment design, air modeling and for moving faster into senior work.
Things you don't need, but that help.
Water and wastewater treatment
Designing the plants that make water drinkable and sewage harmless. The oldest and steadiest part of the job.
Contaminated site cleanup
Investigating and remediating polluted ground and groundwater, often at old industrial sites.
Air quality and permitting
Modeling emissions and getting industrial permits approved. Regulation heavy and well paid.
Stormwater and flooding
Managing runoff and flood risk, and growing fast as storms get heavier.
Solid waste and landfills
Unglamorous, essential, and consistently in demand in every county in the country.
Technical writing
Much of the output is reports and permit applications that regulators and the public will read.
Mapping and data software
Geographic mapping tools and modeling packages are used daily, and employers ask which ones you know.
A summer at a water utility or a state agency
The clearest way to see whether you prefer designing systems or regulating them.
Public speaking
Environmental projects get argued about at public meetings, and the engineer is usually the one explaining them.
The Environmental Protection Agency and every state's environmental agency hire engineers directly, and cities hire them for water, sewer and stormwater systems. Federal hiring runs through a public job site with separate routes for current students, recent graduates and veterans, and the pay is set by grade rather than negotiated. You will usually earn less than at a consulting firm, but the hours are saner, the pension is real, and the work qualifies for Public Service Loan Forgiveness. A lot of people do a few years in government and then move to consulting at a higher level because they know how the regulator thinks.
Day to day, pros and cons, where you'd work.
Mostly an office and a computer: sizing a treatment process, running a model, checking a contractor's submittal, writing the report that goes to the regulator. Then a site visit, which might be a water treatment plant, a landfill, a construction site or a field of monitoring wells at a contaminated property. There is a call with a client who wants the permit faster and a call with an agency reviewer who wants three more things in the application. Deadlines come from permit cycles and construction seasons, not from you.
The good
The hard parts
Things people don't tell you.
The Clean Air Act and the Clean Water Act set limits that somebody has to actually meet, and meeting them takes designed systems. Nearly every environmental engineering job in the country traces back to a rule that says a number cannot be exceeded.
A wastewater plant works by keeping billions of microorganisms alive in tanks and feeding them the waste. The engineer's job is to give those microbes the right oxygen, temperature and time. Get it wrong and the whole plant sours.
You sit the Fundamentals of Engineering (FE) exam around graduation, then work for roughly four years under a licensed engineer before you may take the Principles and Practice of Engineering (PE) exam in your discipline. There is no way to compress the experience in between.
A licensed engineer applies a seal to drawings and reports, and that seal is a personal legal statement that the design is sound. It is why the license takes years, and why a project cannot simply be signed off by whoever is available.
Last checked September 2026. Pay figures are typical full-time annual amounts in United States dollars, based on Bureau of Labor Statistics wage data and published pay scales. They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise.
