Water introduced to surface drainages, such as agricultural and roadway runoff, mine drainage, or coalbed natural gas (CBNG)-produced water, potentially can be of environmental concern. In order to mitigate potential environmental effects, it may be important to be able to trace water discharged to the surface as it infiltrates and interacts with near-surface aquifers. We have chosen to study water withdrawn during CBNG production for isotope tracing in the hyporheic zone because it poses a variety of economic, environmental, and policy issues in the Rocky Mountain states. Ground water quality must be protected as CBNG water is added to semiarid ecosystems. Strontium (Sr) isotopes are effective fingerprints of the...

Description of Work Determine the relative sensitivity of two species of amphibians (i.e. Wood Frogs Rana sylvatica, Cricket Frogs Acris crepitans blanchardi, American Toad Bufo americana) to exposure to acute and chronic levels of nitrate, nitrite and ammonia. This data will be used to evaluate the current ammonia criteria and for possible inclusion in the development of criteria for nitrite and nitrate.

Description of Work The work completed for this template will provide the following information: 1) Generate acute and chronic toxicity data for freshwater mussels and snails to enhance the protection of listed/endangered species in the GL basin; 2) Refine methods and conduct acute and chronic toxicity tests on amphibians; 3) Develop and test methods for conducting chronic toxicity tests for mayflies.
