Job Description
Summary
This job involves using computer models to assess how wastewater from industries, homes, and farms affects South Carolina's rivers and lakes, helping to set pollution limits and restore water quality.
The role supports key environmental programs to protect surface waters under federal clean water laws.
It's a great fit for someone with a science background who enjoys data analysis, fieldwork, and contributing to long-term environmental protection.
Key Requirements
- Master’s degree in natural or physical sciences or related technical field (bachelor’s degree considered with experience)
- Experience developing, calibrating, and applying complex water quality models
- Proficiency in mathematical modeling for pollution assimilative capacity and TMDLs
- Skills in reviewing and analyzing physical, biological, hydrologic, chemical, and geospatial data
- Ability to use ArcGIS and other tools for data inputs and site visits
- Knowledge of Clean Water Act, NPDES permits, and 303(d) impaired waters listing
- Experience in field studies, monitoring, and defending model results for permitting

About the 303d, Modeling, and TMDL Section:
The South Carolina Department of Environmental Services (SCDES) works to protect and restore the quality of surface waters in accordance with the Clean Water Act (CWA). Our 303d, Modeling, and TMDL Section uses water quality data, models, and other tools to help protect and restore surface waters throughout the state.
This program is responsible for or supports critical environmental efforts, including:
- Total Maximum Daily Loads (TMDLs)
- Waste Load Allocations (WLAs) for point sources
- Load Allocations (LAs) for non-point sources
- Effluent limits for NPDES permits
- Water quality certifications under Section 401 of the CWA
- Development of the 303(d) List of Impaired Waters
Joining our team means contributing to science-based decisions that protect South Carolina’s water resources for generations to come.
Under general supervision, the Water Quality Modeler determines the impact of treated wastewater discharges from a wide variety of industrial, domestic and agricultural activities on State waters using simple to very complex computer modeling techniques and scientific principles and methods. Accurately determine the total maximum daily loads (TMDLs) for point and non-point sources of pollution and recommend permit limits based on waste load allocations (WLAs) for specified parameters to be included in NPDES permits.
Responsibilities:
Work as a project manager to determine pollution assimilative capacity for specific waterbodies using appropriate mathematical water quality models.
Accurately and independently develop, calibrate and apply complex computerized mathematical models in determining WLAs and TMDLs.
Using appropriate models, correctly determine recommended load allocations for non-point sources and wasteload allocations for NPDES permitted sources.
Ensure proper determination of treatment levels to maintain water quality standards. Explain, document and defend results for TMDL, WLA and NPDES discharge permitting purposes as appropriate.
Obtain and independently review available physical, biological, hydrologic, chemical and geospatial data to determine data inputs for water quality models and analyses using ArcGIS and other sources. Participate in design and completion of field studies and conduct site visits as required.
Support development of the 303(d) List of Impaired Waters and support TMDL and other field monitoring activities supported by the 303(d), Modeling and TMDL Section.
Other duties as assigned.
Requirements
- A master’s degree in the natural or physical sciences or related technical field
- A bachelor’s degree in the natural or physical sciences or a related scientific field and one (1) year of environmental health or related experience.
- OR an associate degree in the natural or physical sciences or related technical field and at least three (3) years of environmental health or related experience
- OR a high school diploma or GED and at least five (5) years of environmental health or related experience
Applicants indicating college credit or degree(s) on the application may upload an unofficial copy of the transcript as an attachment to the application. Please note that the agency may require an official, certified copy of the transcript or diploma prior to hiring.
Additional Requirements:
Knowledge of water quality data analysis, knowledge of environmental models, such as water quality models.
Knowledge of environmental management practices, environmental science, hydrology, ecology, water chemistry, limnology, and advanced mathematics and statistics.
Strong organizational, quantitative, technical writing, and communication skills are required.
Skill with MS Excel for data manipulation and analysis.
Ability to operate State owned vehicles.
Ability to make presentations in a group setting.
Ability to make visual observations of facilities, samples, plans, specifications, reports, waterbodies, etc.
Experience understanding and analyzing environmental data.
Ability to apply established methodology and scientific principles and incorporate relevant data to develop defensible water quality models and recommendations for discharge permit limits and TMDLs.
Must have a valid SC Driver's License.
Qualifications
- Knowledge or experience with spatial data analysis using ArcGIS.
- Knowledge or experience with water quality field work.
- Knowledge or experience with NPDES permitting.
