Chemical Contaminants and Fish Endocrine and Reproductive Conditions in Lake Mead National Recreation Area - Wastewater Study
July 2007 - June 2011
- Lake Mead National Recreation Area
- Nevada Office
The impacts of urban wastewater to the water quality and aquatic ecosystem of Lake Mead National Recreation Area are not well documented. The objective of this project is to examine the potential effects in fathead minnow of exposure to standard tertiary-treated wastewater effluent from Las Vegas, Nevada. Fathead minnow (Pimephales promelas) is a standard fish model for toxicity testing and in this study will be used as surrogate for fish in Lake Mead. Partial life-cycle (21-day exposures) and multigenerational exposure formats will be used. Multiple endpoints of endocrine a reproductive toxicity will be examined.
