Course Description

Essential Tools for Water Professionals Facing Costly and Complex Compliance Issues in Impaired Water Resources
Course ID: 
Continuing Education Units: 


Meeting water quality standards in surface and ground water bodies, as well as discharge flows, can be complicated by the lack of adequate information on the sources of contamination. And making an incomplete or inaccurate assessment of sources contributing to the impairment of water bodies can be costly and time consuming, resulting in a failure to meet or maintain compliance with critical water standards.

This two-day course provides an in-depth examination of problems that can be approached using contaminant trackdown studies. Participants will learn about methods for identifying critical sources of contamination such as nutrients, pathogens and toxins, in surface and ground water resources, and in municipal and industrial distribution systems. In addition, they will take away practical and realistic tools for saving time and money by using contaminant trackdown studies to tackle impaired water scenarios ranging from small-scale systems, such as lakes, to complex watersheds and municipal distribution systems.

Examples and case studies, as well as several hands-on breakout sessions, will be included to provide participants with real-world experience in conducting a contaminant trackdown study.

Course Topics


Topics covered in this course include:

·      Overview of contaminant issues that impair water quality.

·      Scenarios where use of a contaminant trackdown study can help development of solutions for impaired waters or contaminated effluents.

·      Key issues in selection of appropriate tracers to target key contaminants, such as nutrients, pathogens, heavy metals and PCBs.

·      Trackdown approaches that include use of characteristics inherent in the contaminants of concern, co-occurring contaminants, GIS, or intentional injection of non-toxic tracers.

·      Critical aspects of contaminant trackdown studies, including correlation of tracer and contaminant transport and fate, sampling frequency and spatial distribution, and data analysis and constraints.

·      Case studies and examples of real-world problems will be included throughout the course.

·      Three breakout sessions will be included to provide hands-on exercises for participants.

What to Bring

Pen or pencil to take notes. Please bring paper if you do not want to write your notes on your manual. Lunch will be on your own but drinks and snacks will be provided throughout each day.
