What Does an Environmental Scientist Do?
Environmental Scientists study air, water, and soil to assess contamination levels and develop strategies to protect ecosystems and public health [1]. Their work ranges from conducting Phase I and Phase II Environmental Site Assessments under ASTM standards, to designing groundwater-monitoring networks, to evaluating the environmental impact of proposed construction or industrial projects. They collect field samples, analyze laboratory data, model contaminant transport, and prepare reports for regulatory agencies, businesses, and the public.
The role blends fieldwork — drilling soil borings, collecting water samples from monitoring wells, conducting habitat surveys — with office-based analysis and report writing. Environmental Scientists must navigate federal regulations (CERCLA, RCRA, Clean Water Act, Clean Air Act, NEPA) and their state equivalents, making regulatory knowledge as important as scientific expertise [3].
Core Responsibilities
- Conduct environmental site assessments — Perform Phase I (records review) and Phase II (sampling) assessments to identify contamination at properties.
- Collect and analyze samples — Gather air, water, soil, and sediment samples using proper chain-of-custody procedures; interpret laboratory analytical results.
- Assess contamination risks — Evaluate exposure pathways, calculate risk-based screening levels, and determine whether site conditions exceed regulatory thresholds.
- Develop remediation plans — Design cleanup strategies including pump-and-treat, soil vapor extraction, bioremediation, and monitored natural attenuation.
- Prepare environmental impact assessments — Evaluate the potential effects of proposed projects on air quality, water resources, wetlands, and wildlife habitat.
- Write technical reports — Produce site investigation reports, compliance documentation, and regulatory submissions for EPA, state agencies, and clients.
- Monitor ongoing conditions — Design and execute long-term monitoring programs for groundwater, surface water, and air quality.
- Ensure regulatory compliance — Advise organizations on CERCLA, RCRA, Clean Water Act, NEPA, and state environmental regulations.
- Model contaminant fate and transport — Use software tools to predict how pollutants move through soil, groundwater, and atmosphere.
- Coordinate with regulatory agencies — Interface with EPA, state DEQ/DEP offices, and local authorities on permits, notifications, and corrective actions.
- Conduct ecological assessments — Evaluate impacts on endangered species, wetlands, and sensitive habitats; perform biological surveys.
- Support ESG and sustainability programs — Help organizations measure environmental footprints, set reduction targets, and report sustainability metrics.
Required Qualifications
- Education: Bachelor's degree in environmental science, biology, chemistry, geology, or a related natural science [1].
- Field skills: Experience with environmental sampling techniques, field equipment, and chain-of-custody procedures.
- Regulatory knowledge: Familiarity with CERCLA, RCRA, Clean Water Act, Clean Air Act, and NEPA.
- Data analysis: Ability to interpret laboratory data and apply statistical methods to environmental datasets.
- Report writing: Clear technical writing for regulatory submissions and client deliverables.
- Physical requirements: Ability to work outdoors in varied conditions and carry field equipment.
Preferred Qualifications
- Master's degree in environmental science, hydrogeology, or environmental engineering.
- Professional certifications: PE, PG (Professional Geologist), or CHMM (Certified Hazardous Materials Manager).
- OSHA 40-Hour HAZWOPER certification.
- Experience with GIS (ArcGIS, QGIS) and contaminant transport modeling (MODFLOW, BIOSCREEN).
- State-specific environmental professional credentials.
- Experience with PFAS, emerging contaminants, or brownfield redevelopment.

Work Environment
Environmental Scientists split time between office analysis and field investigations [1]. Fieldwork may involve remote locations, industrial sites, or contaminated properties where PPE (steel-toed boots, Tyvek suits, respirators) is required. Weather exposure is constant during outdoor sampling campaigns. Most positions are full-time with some overtime during project deadlines or emergency response events. Travel within a regional territory is typical for consulting roles. Federal government positions offer the highest median salary but may involve relocation [3].
Salary Range
The BLS reports the following for environmental scientists and specialists as of May 2024 [1]:
| Percentile | Annual Wage |
|---|---|
| 10th | $50,130 |
| 25th | $62,250 |
| 50th (Median) | $80,060 |
| 75th | $102,630 |
| 90th | $134,830 |
Federal government roles pay the highest median ($113,980), followed by consulting firms and state/local government ($76,000-$77,000). Environmental consultants in high-demand specializations (PFAS remediation, brownfields, ESG reporting) command premium rates [4].
Career Growth
Entry-level staff scientists advance to project scientist and senior scientist within 3-6 years, then to project manager and principal scientist roles that carry business-development and client-management responsibilities. Some specialize in emerging areas like PFAS remediation, climate-risk assessment, or ESG consulting. Others transition to regulatory agency positions, environmental law (with additional education), or corporate sustainability leadership. The convergence of environmental science with data analytics and remote sensing is creating new interdisciplinary career paths [5].
