Core Responsibilities

Primary Functions

Design, implement, and maintain water quality and hydrologic monitoring programs tailored to project objectives, including selecting monitoring locations, frequency, and analytes to meet regulatory and study goals.
Plan and execute field sampling campaigns for surface water, groundwater, stormwater, and wastewater, ensuring chain-of-custody, sample preservation, proper field measurements (pH, dissolved oxygen, conductivity, turbidity), and adherence to SOPs and safety protocols.
Coordinate with accredited laboratories and perform in-house laboratory analyses using spectrophotometry, ion chromatography, gas chromatography, and other analytical instrumentation; interpret instrument data and ensure method detection limits meet project requirements.
Conduct rigorous QA/QC on field and laboratory data by implementing blank, duplicate, spike recovery checks, calibration records, and data validation steps to ensure defensible datasets for regulatory submittals and litigation support.
Perform statistical analyses and trend detection on multi-year water quality and flow datasets using R, Python, or statistical software to identify exceedances, seasonal patterns, pollutant sources, and long-term changes.
Develop and maintain relational databases and data pipelines (SQL, PostgreSQL, or cloud-based storage) for consolidated water monitoring data, metadata, and QA/QC flags to enable reproducible analysis and reporting.
Integrate SCADA, telemetry, and sensor data streams with sampled chemistry datasets to perform near-real-time assessments, automated alerts for exceedances, and operational support for treatment plants or pumping stations.
Produce clear, accurate technical reports, regulatory submittals, monitoring plans, and standard operating procedures that synthesize analytical results, methods, QA/QC findings, and management recommendations for internal and external stakeholders.
Create maps, spatial analyses, and visualizations in ArcGIS/ArcGIS Pro or QGIS to illustrate sampling networks, watershed boundaries, pollution sources, and model outputs for reports and presentations.
Support hydrologic and hydraulic modeling efforts (e.g., HEC-RAS, SWMM, MIKE SHE) by preparing input datasets, calibrating models against observed flow and stage data, and interpreting model results to support flood risk, pollutant transport, and infrastructure planning.
Collaborate with permitting and compliance teams to prepare documentation for regulatory programs including NPDES, SDWA, Clean Water Act Section 303(d) assessments, Total Maximum Daily Load (TMDL) studies, and drinking water monitoring requirements.
Develop pollutant source apportionment and diagnostic analyses (e.g., land-use correlations, load calculations, event-based storm sampling) that inform adaptive management actions and targeted mitigation strategies.
Manage field crews and subcontractors during sampling events, including training on sampling techniques, safety procedures, equipment use, and data recording to maintain consistency and defensibility across projects.
Maintain and calibrate field instrumentation (multiparameter sondes, flow meters, autosamplers) and coordinate preventative maintenance schedules to reduce downtime and preserve data quality.
Prepare and present technical findings to clients, municipalities, regulators, and community stakeholders through briefings, technical memos, and public-facing presentations, translating technical jargon into actionable insights.
Lead and contribute to grant proposals, scope of work development, and budget estimates by providing technical justification, sampling and analysis plans, and deliverable schedules.
Review scientific literature, regulatory guidance, and emerging technologies in water monitoring (passive samplers, environmental DNA, sensor networks) to recommend improvements and innovations for monitoring programs.
Apply health and safety best practices in confined space entry, near-water operations, and hazardous sample handling; maintain compliance with OSHA, HAZWOPER, and site-specific safety programs.
Archive and document datasets, field logs, laboratory reports, and metadata in accordance with company and regulatory retention policies to ensure traceability and audit readiness.
Support litigation and enforcement actions by preparing defensible data packages, chain-of-custody documentation, and expert summaries when required.
Perform budget tracking, procurement, and equipment inventory management for field and laboratory operations to ensure program efficiency and cost control.
Collaborate cross-functionally with engineering, planning, and operations teams to incorporate monitoring results into asset management, treatment optimization, and capital improvement planning.
Pilot and evaluate new sensors, automated samplers, and cloud-based monitoring platforms, developing validation plans and cost-benefit analyses to scale up successful technologies.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Mentor junior staff and interns on sampling techniques, data analysis workflows, and report writing.
Assist in community outreach, educational workshops, and public meeting preparation to communicate monitoring efforts and results.
Help maintain certification and training records for laboratory and field personnel.
Support emergency response for water contamination incidents by mobilizing sampling teams and rapidly synthesizing analytical results.
