AQUATOX Training Workshops
On this page:
A one-day short course on AQUATOX was presented as part of the Society of Environmental Toxicology and Chemistry (SETAC) North America 31st Annual Meeting, held November 7-11, 2010 in Portland, OR.
The objective of the short course was to familiarize users of diverse backgrounds with the capabilities of AQUATOX for use in a variety of regulatory settings. The course included comparisons with other dynamic ecosystem models used for risk assessment. Examples of applications covered the impact of nutrient, sediments, and toxic organics on a variety of ponds, lakes, reservoirs, rivers, and an estuary.
Occasionally the US EPA offers a comprehensive three-day course. It is similar in scope to the one-day course except that it covers more aspects of the model in greater depth, with diverse hands-on exercises. Such a course was held on AQUATOX Release 3.1 beta in December 2010, November 2011 at US EPA Region 6 in Dallas, TX, and November 2012 at the Columbia River Intertribal Fish Commission in Portland, OR, respectively.

- Four daily files
- (zipped file) Introduction to model capabilities, modeling plants and animals, potential applications, model calibration and performance
- (zipped file) Modeling nutrients and nutrient effects, application in support of water quality management, AQUATOX and BASINS, sediment effects, fate and bioaccumulation of organic chemicals
- (zipped file) Uncertainty analysis demonstration
- (zipped file) Modeling estuaries, toxicity of organic chemicals and inorganic sediments
The following two labs from the course at CRITFC (CRITFC Labs 6-7) are based on a very informative study and exemplify in-depth analyses of a stream in Oregon with abundant data for multiple years. The lab tracks two bioaccumulative pesticides, one that exceeds the action level in runoff and the other a legacy pesticide that is sequestered in periodically scoured sediments. The study is the first application to simulate migration and exposure of anadromous fish (lamprey and chinook salmon). Lab 7 builds on the previous bioaccumulation lab to examine time-dependent lethality, sublethal toxicity exemplified by growth reduction, and indirect effects due to reduction in predation.
