ATW 2010 Short Course

Title: Industrial Effluent Toxicity Identification Evaluations (TIEs)

Instructors: Scott Hall and Rick Lockwood, ENVIRON International Corporation, Brentwood , TN, USA

Course Description: This half-day short course will describe the conventional approaches to conducting laboratory TIE studies with industrial effluents, emphasizing laboratory techniques and data interpretation considerations unique to industrial discharges.  Topics to be covered include: interpretation of dissolved solids interference; appropriate use of treatment blanks; use of species-sensitivity patterns to identify toxicants; interpretation of data with apparent conflicts in mode of toxicity removal; consideration of water quality parameters altering chemical toxicity; and, appropriate extrapolation of literature-reported toxicity values to effluent conditions.  A focus of the course will be the use of non-conventional approaches such as mock effluents, “percent composition” testing, and approaches using TIE treatments that also develop preliminary engineering treatability data to identify candidate control technologies.  Case studies of approaches that successfully identify total dissolved solids (TDS), major ion components of TDS, fish pathogens, heavy metals, and nitrate and nitrite in industrial effluents will be presented.  A unique TIE utilizing freshwater mussels and identifying potassium as the effluent toxicant will also be presented.  In addition to the case studies, example data sets for course participant interpretation will be used to engage participants and encourage interaction with instructors.

Instructor biographies :
Mr. Hall holds a Masters Degree in Aquatic Toxicology and has approximately 25 years experience conducting effluent toxicity tests and TIE studies with freshwater and marine organisms.  He has published numerous peer-reviewed articles in these and related areas, and served as the project manager on numerous industrial effluent TIE studies.  Mr. Hall served on the Society of Environmental Toxicology and Chemistry (SETAC) Expert Panel for Whole Effluent Toxicity (WET) testing, and served as a SETAC short course instructor for WET and TIE courses.

Mr. Lockwood has approximately 25 years experience as an aquatic biologist and toxicologist, including 14 years conducting WET tests and TIEs with industrial effluents.  He oversees and implements laboratory TIE studies, develops laboratory treatment techniques to address suspect toxicants, and with engineering staff develops approaches amenable to full-scale waste treatment application in industrial effluents.  Mr. Lockwood was instrumental in developing the testing and approach for a TIE with freshwater mussels that will be featured in this short course.
