Environmental Engineering in Kansas

Kansas's environmental engineering market — 485 employed professionals ranked #33 nationally at a $76,000 average salary — reflects a state whose environmental engineering practice is shaped by its position as a major agricultural state, a significant producer of oil and natural gas (particularly in the Hugoton natural gas field in southwest Kansas), a growing aviation manufacturing industry, and the environmental legacy of underground storage tank contamination across hundreds of rural communities. Kansas's environmental engineering community is modest in size but technically engaged with genuinely complex challenges — particularly the protection of the High Plains (Ogallala) Aquifer, which underlies western Kansas and is one of the most important and most threatened freshwater resources in North America. Major Employers: The Kansas Department of Health and Environment (KDHE) — specifically its Environment Division — is the state's primary environmental regulatory agency, employing environmental engineers across its Bureau of Environmental Remediation (Superfund and VCP), Bureau of Air and Radiation, Bureau of Water (NPDES permitting, drinking water), and the Storage Tank Section. The Kansas Department of Agriculture (KDA) administers agricultural water quality programs including CAFO permits and nutrient management plan review in a regulatory partnership with KDHE. Environmental consulting firms serving Kansas include AECOM, Terracon (Olathe, Kansas — one of Terracon's largest offices), Smith Environmental Services, and Burns & McDonnell (Kansas City, Missouri-based but with major Kansas practice). Cessna/Textron Aviation and the Wichita aerospace manufacturing cluster employ environmental engineers for manufacturing facility air quality compliance, chlorinated solvent remediation from historical degreasing operations, and stormwater management. Koch Industries (Wichita headquarters) employs environmental engineers for its diverse refining, chemical, and manufacturing operations. The Ogallala Aquifer's protection is increasingly involving environmental engineering for water quality assessment, agricultural chemical monitoring, and irrigation management programs administered by Kansas water management districts. Key Practice Areas: Petroleum UST remediation is Kansas's largest environmental engineering practice — the state has thousands of leaking underground storage tank cases from gasoline stations across hundreds of rural communities, managed by KDHE's Storage Tank Section and remediated under the KDHE Petroleum Storage Tank (PST) program. Chlorinated solvent remediation from Wichita's aerospace manufacturing history is a significant environmental engineering practice — decades of trichloroethylene (TCE) and perchloroethylene (PCE) use in aircraft manufacturing degreasing operations created significant chlorinated solvent contamination in the Wichita urban aquifer, now managed under a complex groundwater management program involving multiple responsible parties and KDHE oversight. High Plains Aquifer water quality engineering is a growing practice as nitrate from agricultural fertilizer application and naturally occurring contaminants (arsenic, radium) affect drinking water quality in western Kansas communities dependent on the Ogallala Aquifer for their only water supply.

Kansas environmental engineering careers offer early project management responsibility, genuine exposure to agricultural and petroleum environmental engineering specializations with national applicability, and a cost of living that allows environmental engineers to build personal financial stability at rates not achievable in higher-cost markets. Typical Career Trajectory:

• Staff Environmental Engineer (0–3 years): $55,000–$70,000 — Entry-level roles at KDHE, consulting firms (Terracon, AECOM, Smith Environmental), or industrial environmental departments. Kansas entry-level environmental engineers most commonly begin in UST/petroleum remediation or Phase I/II ESA work given the volume of these activities in the Kansas market.
• Project Environmental Engineer (3–6 years): $70,000–$88,000 — Managing KDHE PST remediation projects, voluntary cleanup program sites, or air quality compliance programs for Wichita aerospace manufacturing clients. PE licensure obtained. KDHE-specific regulatory knowledge — particularly the PST program's tier-based assessment and remediation procedures — is the defining credential for Kansas contaminated site environmental engineers.
• Senior Environmental Engineer (6–12 years): $88,000–$110,000 — Leading multi-site UST portfolios, complex chlorinated solvent remediation programs, or KDHE permit program technical work. Senior engineers at Kansas consulting firms often serve as the primary technical and regulatory interface for major Kansas petroleum or aerospace environmental clients.
• Principal / Practice Leader (12+ years): $110,000–$140,000+ — Consulting firm practice leadership or KDHE division management. The most senior environmental engineering positions in Kansas are at the larger consulting firms serving the Wichita market and at KDHE's central office in Topeka.

Petroleum Remediation Specialization: Kansas's enormous petroleum UST remediation market creates a clear career specialization pathway — environmental engineers who become expert in KDHE's tiered assessment procedures, petroleum hydrocarbon fate and transport modeling, and the state's risk-based corrective action framework develop a credential that is broadly applicable to the petroleum remediation practice across the central U.S. region.

Kansas's $76,000 average environmental engineering salary is near the national average and Kansas's low cost of living provides strong effective purchasing power. Kansas has a graduated income tax (ranging to 5.7%) — moderate nationally. Wichita Metro: Kansas's primary environmental engineering market. Aerospace manufacturing environmental compliance and consulting environmental engineering salaries of $76,000–$112,000 for experienced engineers. Cost of living in Wichita is approximately 12–18% below the national average. Median home prices of $190,000–$270,000 in Wichita — among the most affordable major cities in the central U.S. for professional homeownership. Kansas City Metro (Kansas side): Consulting and corporate environmental engineering at $78,000–$115,000 with cost of living near or slightly below the national average. Access to the much larger Kansas City (Missouri) environmental consulting market. Topeka (KDHE): State government environmental engineering at $60,000–$88,000 for staff engineers, with management roles to $95,000+. Very affordable Topeka cost of living. Western Kansas (Oil and Gas / Agriculture): Agricultural and petroleum environmental engineering at $65,000–$90,000 with a very low cost of living in the small rural communities of the High Plains. Purchasing Power: An environmental engineer earning $76,000 in Wichita has purchasing power roughly equivalent to $105,000–$115,000 in Dallas or $150,000+ in Denver — a compelling financial case for environmental engineers who value personal financial security and homeownership over urban amenities.

The Kansas State Board of Technical Professions administers professional engineering licensure for environmental engineers. Kansas's process is efficient with standard reciprocity with neighboring states. Kansas PE Licensure Pathway:

• FE Exam: Standard NCEES format. University of Kansas (Lawrence — strong civil and environmental engineering programs), Kansas State University (Manhattan — strong civil and agricultural engineering programs), and Wichita State University (with aerospace engineering ties relevant to environmental compliance work) prepare Kansas's environmental engineering pipeline. KU's water resources and environmental engineering programs have ties to the Ogallala Aquifer research community.
• 4 Years of Progressive Experience: Under PE supervision across petroleum remediation, agricultural water quality, air quality, and environmental compliance disciplines.
• PE Environmental or Civil Engineering Exam: Standard NCEES exams accepted. Kansas environmental engineers most commonly use the Environmental Engineering PE exam given the petroleum remediation and water quality focus of the state's dominant practice areas.

Kansas-Specific Regulatory Credentials: KDHE Petroleum Storage Tank (PST) program familiarity — the state's tiered assessment procedure (Tier 1 through Tier 3 risk-based approach) and the environmental professional qualifications required for tank site assessment and cleanup work. KDHE Bureau of Environmental Remediation (BER) Voluntary Cleanup and Property Redevelopment Program (VCP) procedures. Kansas NPDES General Permit requirements under KDHE's delegated NPDES program — including Kansas's CGP for construction stormwater and the MSGP for industrial facilities. Key Professional Certifications: CHMM — valued for industrial and petroleum environmental practice. CPESC — useful for Kansas's active construction and highway environmental compliance market. Licensed Environmental Professional (LEP) equivalents — Kansas does not have a state LEP program, but Registered Environmental Manager (REM) credentials from NREP are used by some Kansas environmental professionals. HAZWOPER 40-hour — required for contaminated site field work across the state's active petroleum and Superfund remediation market.

Kansas's environmental engineering outlook is stable with emerging opportunities in climate-related agricultural water management and growing demand for aerospace manufacturing environmental compliance engineering as Wichita's aircraft industry navigates new environmental regulations. Ogallala Aquifer Protection Engineering: The High Plains (Ogallala) Aquifer underlies approximately 30% of Kansas and provides water for 85% of western Kansas residents and the state's most productive irrigated agriculture. The aquifer's sustained depletion — water levels in some areas have declined 30+ feet since pre-irrigation levels — is creating growing demand for environmental engineers specializing in aquifer management, agricultural water use efficiency, and the assessment of alternative water supply options. Kansas's Water Vision process for long-term water supply planning is creating a policy framework that will require environmental engineering implementation support. PFAS at Air National Guard and Military Sites: Kansas Air National Guard bases (McConnell AFB in Wichita, Forbes Field in Topeka) and other Kansas military facilities used AFFF firefighting foam for decades, and PFAS contamination investigations at these sites are generating new environmental engineering workscopes. KDHE has adopted PFAS interim groundwater standards that are driving investigation programs at Kansas military and industrial sites. Aerospace Environmental Compliance Evolution: Wichita's Spirit AeroSystems, Textron Aviation, and Learjet manufacturing operations face increasingly complex air quality and hazardous materials requirements — particularly for emerging substances (PFAS replacements for surface treatments, alternative degreasing solvents for TCE) — creating growing demand for environmental engineers with aerospace manufacturing compliance expertise. Rural Water Infrastructure: Kansas's rural water systems — many dating to the 1950s–1970s — require significant investment and environmental engineering for source water protection, treatment upgrades for nitrate and arsenic compliance, and distribution system rehabilitation. Workforce Projection: Environmental engineering employment in Kansas is expected to grow 4–6% over the next five years, with water resource management and aerospace environmental compliance as the primary growth areas.

Environmental engineering in Kansas is grounded in the prairie — managing the environmental consequences of agriculture, petroleum extraction, and manufacturing across a vast, flat landscape where the environmental engineering challenges are as wide open as the horizon. At a Consulting Firm (Wichita — Aerospace and Petroleum): An environmental engineer on a Monday morning might start by reviewing monitoring well data from a quarterly sampling event at a former degreasing facility on the Wichita urban aquifer — comparing trichloroethylene (TCE) and cis-1,2-dichloroethylene (DCE) concentrations in the plume's monitoring wells to the KDHE risk-based cleanup standards and updating the site's groundwater contour map for the semi-annual KDHE submittal. After the data review, the engineer is on a call with a Cessna/Textron Aviation environmental manager discussing the annual review of the facility's air quality permit emissions inventory — checking whether new painting operations added to the production floor are within the facility's Title V permit's synthetic minor source thresholds for VOC and HAP emissions. In the afternoon, the engineer drives to a former gas station site in rural Sedgwick County for a KDHE PST Tier 2 site assessment — collecting soil samples at specified depths around the former UST excavation area and logging the soil conditions for the site assessment report. At KDHE (Topeka): A KDHE environmental engineer might spend a morning reviewing a CAFO permit application for a 5,000-head beef cattle feedlot in Finney County — evaluating the facility's waste management plan, the separation distances from waterways and domestic wells, and whether the proposed stocking density is consistent with available land for manure application. Kansas Lifestyle: Kansas offers environmental engineers an honest, affordable quality of life defined by the open sky of the Great Plains, excellent pheasant hunting and lake fishing, and the uncomplicated hospitality of Kansas communities where neighbors know each other and housing is genuinely accessible. Wichita's improving food and arts scene and the Flint Hills tallgrass prairie's extraordinary landscape (the largest remaining tallgrass prairie in North America) provide the outdoor and cultural life that Kansas environmental engineers value — a life defined by wide spaces and genuine community rather than urban density.
