Core Responsibilities

Primary Functions

Plan, design, and implement routine and special-purpose water quality monitoring programs for surface water, groundwater, stormwater, and wastewater to meet organizational objectives and regulatory requirements (e.g., NPDES, SDWA, TMDL monitoring).
Conduct field sampling of physical, chemical, and biological parameters (e.g., pH, DO, conductivity, nutrients, metals, fecal indicator bacteria, HABs) using standardized protocols and maintain detailed chain-of-custody documentation.
Prepare sampling plans, Standard Operating Procedures (SOPs), and Quality Assurance Project Plans (QAPPs) tailored to project scope, site conditions, and permit requirements.
Oversee and coordinate sample handling, preservation, and delivery to contract or in-house laboratories, ensuring proper containers, preservatives, holding times, and QA/QC samples (blanks, duplicates, spikes).
Perform on-site instrument calibration, maintenance, troubleshooting, and documentation for field sensors and probes (multiparameter sondes, pH/DO meters, turbidity meters) to ensure data accuracy and reliability.
Lead or support laboratory analyses, including spectrophotometry, ion chromatography, ICP-MS/ICP-OES, and microbial methods (IDEXX, membrane filtration), and verify analytical results against QA/QC acceptance criteria.
Collect, validate, and manage water quality datasets; perform statistical analyses, trend detection, and data visualization using tools such as R, Python, Excel, or specialized environmental software.
Interpret water quality data in the context of regulatory standards (e.g., state water quality standards, MCLs, permit limits) and provide technical guidance on exceedances, data qualification, and corrective actions.
Prepare technical reports, monitoring summaries, permit submittals, and regulatory correspondence that clearly present methods, results, trends, and management recommendations for clients, regulators, and stakeholders.
Support development and implementation of Total Maximum Daily Load (TMDL) studies, load calculations, pollutant source assessments, and watershed management plans.
Evaluate point and nonpoint source impacts, stormwater discharges, industrial effluents, and treatment plant performance; recommend and design best management practices (BMPs) and treatment improvements.
Use GIS to map sampling locations, watershed boundaries, land use, and pollutant sources; produce maps and spatial analyses to support monitoring design and reporting.
Conduct habitat assessments, biological surveys (macroinvertebrates, periphyton), and toxicity assessments as part of integrated water quality evaluations.
Coordinate with municipal, state, and federal agencies on permitting, compliance inspections, and enforcement responses; prepare permit applications and monitoring schedules (e.g., NPDES permits, MS4 SWMPs).
Maintain field safety programs and ensure compliance with site-specific safety plans, PPE requirements, confined space entry, HAZWOPER protocols, and boat/ATV safety when applicable.
Manage, train, and supervise field crews, contractors, and interns; develop training materials and ensure consistent application of methods and QA/QC procedures.
Deploy, configure, and maintain continuous monitoring equipment (real-time sondes, telemetry, dataloggers, SCADA interfaces); monitor data streams for anomalies and coordinate maintenance with vendors.
Support laboratory quality systems and accreditation activities (e.g., ELAP, ISO 17025), participate in audits, and implement corrective actions to maintain analytical integrity.
Prepare and support grant applications, project proposals, and budgets related to water quality monitoring, restoration, and research initiatives.
Lead community outreach, public education, and stakeholder engagement efforts to communicate monitoring results, promote source-water protection, and facilitate collaborative watershed solutions.
Design and run water quality modeling exercises (e.g., QUAL2K, SWMM, HSPF, SWAT) to predict pollutant fate and transport, evaluate management scenarios, and support decision-making.
Investigate and respond to incidents of contamination, algal blooms, spills, and public health advisories; coordinate with public health officials and issue notifications as required.
Implement data management best practices: metadata documentation, database maintenance (SQL or environmental databases), and secure archival of raw and processed data.
Evaluate emerging contaminants (PFAS, pharmaceuticals, pesticides) and adapt monitoring strategies and analytical workflows to incorporate new analytes of concern.

Secondary Functions

Support ad-hoc monitoring projects, pilot studies, and proof-of-concept sensor deployments to evaluate new technologies and methods.
Assist in procurement, vendor evaluations, and contract management for laboratory services, analytical instruments, and field equipment.
Contribute to environmental impact assessments, feasibility studies, and engineering design teams to incorporate water quality considerations into capital projects.
Provide technical support for regulatory inspections, public hearings, and stakeholder meetings; prepare presentations and outreach materials.
Develop continuous improvement initiatives for sampling efficiency, data quality, and cost control in monitoring programs.
Mentor junior staff and interns; participate in cross-functional teams to align water quality work with organizational goals.
Track and summarize regulatory changes, scientific literature, and best practices to ensure program currency and compliance.
Participate in multi-disciplinary emergency response teams to evaluate water quality risks during natural disasters and industrial incidents.
