Core Responsibilities

Primary Functions

Conduct systematic field sampling of surface water, groundwater, drinking water, wastewater, soil, sediment, and air according to approved sampling plans, Standard Operating Procedures (SOPs), and regulatory guidance (EPA, state agencies), ensuring representative, uncontaminated samples.
Collect discrete and composite samples and perform in-field measurements (temperature, pH, conductivity, dissolved oxygen, turbidity, ORP) using handheld meters and multiparameter sondes with documented calibration and QA/QC records.
Operate and maintain continuous monitoring stations, data loggers, automatic samplers, and meteorological sensors; download, validate, and maintain time-series datasets and instrument logs.
Calibrate, troubleshoot, and repair field instrumentation (e.g., YSI, Hach, Thermo Fisher sensors, flow meters, gas monitors) and coordinate maintenance and service with vendors as needed.
Prepare, label, preserve, and package samples for shipment to certified laboratories following chain-of-custody procedures, sample preservation techniques, and shipping regulations (DOT, UN3373 where applicable).
Perform basic laboratory analyses on-site or in-house (e.g., turbidity, pH, conductivity, dissolved oxygen, basic colorimetric tests) and document analytical results and QC checks per SOPs.
Implement Quality Assurance / Quality Control protocols, including field blanks, duplicates, calibration checks, and documentation of deviations; identify and escalate data quality issues.
Maintain and update field notebooks, electronic logs, GPS coordinates, site photos, and metadata to support defensible datasets and regulatory submittals.
Conduct site reconnaissance and pre-sampling inspections to assess access, health and safety hazards, potential cross-contamination sources, and to determine appropriate sampling methods.
Support environmental permitting and compliance monitoring efforts by collecting required monitoring data and preparing documentation for regulatory agencies and client audits.
Install, service, and decommission monitoring wells, piezometers, samplers, and stream gauges under supervision or per project plans, following safe work practices and permit requirements.
Collect and monitor air quality samples (PM2.5, PM10, volatile organic compounds, gases) using portable monitors, sorbent tubes, canisters, and real-time instruments as specified in monitoring plans.
Use GPS devices and GIS software to locate sampling points, map monitoring networks, and maintain accurate site spatial data for project deliverables.
Drive to remote and urban sampling locations and safely perform fieldwork in diverse environmental conditions, including confined spaces, wetlands, and at industrial or construction sites.
Prepare clear, concise field reports, data summaries, chain-of-custody forms, and routine monitoring deliverables for project managers and clients within established deadlines.
Enter, validate, and manage environmental monitoring data in databases, spreadsheets, and environmental information management systems; perform basic data QA/QC, flagging, and trend checks.
Respond to environmental incidents, spills, and emergency monitoring requests to perform immediate sampling, screening, and documentation to support incident response and regulatory reporting.
Follow and enforce health and safety procedures on-site, including use of personal protective equipment (PPE), HAZWOPER and confined space protocols, and maintain awareness of chemical, biological, and physical hazards.
Maintain field vehicle, sampling equipment, supplies, and a consumables inventory; coordinate reordering and ensure readiness for successive field campaigns.
Train and mentor junior technicians and subcontracted field staff on sampling techniques, SOPs, safety, and data handling, ensuring consistent execution across teams.
Coordinate with project scientists, engineers, and lab personnel to ensure sampling methods and schedules meet study objectives and laboratory detection limits.
Participate in field planning, logistics, and client meetings; provide input on sampling design, frequency, and instrumentation to optimize data quality and project cost-efficiency.
Prepare and assist with permit applications, monitoring plan updates, and technical attachments that document methodology, chain-of-custody, and QA/QC practices for regulatory review.
Maintain confidentiality of client data and adhere to company policies for data security, record retention, and professional conduct.

Secondary Functions

Support ad-hoc data requests by extracting, formatting, and visualizing environmental monitoring datasets for internal teams and external stakeholders.
Assist in developing and improving field data templates, mobile data collection forms, and standard operating procedures to streamline data capture and reduce errors.
Contribute technical input to the organization’s environmental data strategy, including recommendations for sensor networks, telemetry, cloud data storage, and automated reporting.
Collaborate with project managers, scientists, and clients to translate monitoring objectives into practical field requirements, instrumentation choices, and QA/QC plans.
Participate in project planning, resource allocation, and daily field briefings; document lessons learned and recommend process improvements to increase efficiency and data quality.
