Environmental Scientist Jobs in Pennsylvania: Frequently Asked Questions
How do you become an environmental scientist in Pennsylvania?
Most environmental scientists in Pennsylvania enter the field with a bachelor's degree in environmental science, geology, chemistry, or a closely related discipline, then build credentials through professional certification. The Pennsylvania Department of Environmental Protection does not require a single universal state license, but many employers and project roles require a Professional Geologist license issued by the Pennsylvania State Registration Board for Professional Engineers, Land Surveyors and Geologists. Earning a credential like the CHMM or HAZWOPER certification also strengthens candidacy for compliance and remediation roles.
How much do environmental scientists make in Pennsylvania?
Environmental scientists in Pennsylvania earn a median of about $76,110 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $50,660 for the lowest 10% to over $125,520 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire environmental scientists in Pennsylvania?
Employers hiring environmental scientists in Pennsylvania right now include Langan Engineering and Environmental Services, Weston Solutions, and RETTEW, based on current listings on Migrate Mate as of November 2026. Pennsylvania's concentration of consulting firms, energy companies, and state regulatory agencies means demand is spread across both the private sector and government roles throughout the state.
Which Pennsylvania cities have the most environmental scientist jobs?
Pittsburgh, Philadelphia, and West Chester have the most environmental scientist openings in Pennsylvania. Philadelphia leads because of its dense concentration of consulting firms and proximity to industrial Superfund sites, Pittsburgh draws remediation and energy-sector work tied to its legacy manufacturing and active natural gas development, and Harrisburg generates consistent openings through Pennsylvania Department of Environmental Protection headquarters and regional offices.
Are there remote environmental scientist jobs in Pennsylvania?
Yes, but they're limited. Much of the role involves fieldwork, site inspections, and sample collection that requires physical presence. About 47% of environmental scientist openings tied to Pennsylvania are remote or hybrid as of November 2026, and those positions tend to be concentrated in data analysis, report writing, regulatory review, and GIS-based project work rather than field-heavy assignments.
How can I get hired as an environmental scientist in Pennsylvania with little or no experience?
The most realistic entry path is applying for field technician or environmental analyst roles at Pennsylvania-based consulting firms, which routinely hire recent graduates for supervised site work and sampling. Large firms like AECOM and Arcadis run associate-level programs that bring in candidates without deep experience. A HAZWOPER 40-hour certification or a completed internship with a PADEP regional office gives an immediate edge, and adjacent roles in water quality monitoring or laboratory analysis at utilities or county conservation districts are a common lateral door into the profession.
