Water Rights Evaluation

Full Description

Gradient provided expert evaluation and testimony in a water rights case filed in the Supreme Court of the United States. We used hydrological modeling and data analysis to assess historical changes in water use, groundwater conditions, and stream flows.

Risk Assessment of Refrigerants with Reduced Global Warming Potential

Full Description

Gradient assessed the utility and risks of using refrigerants with low global warming potential in retail store and commercial kitchen applications. We determined potential exposure risks and evaluated potential chemical leakage and dispersion using simulations and chemical testing.

Regulatory Evaluation of the Clean Power Plan

Full Description

Gradient reviewed the approach used to calculate health co-benefits when assessing impacts of the federal Clean Power Plan. We evaluated the scientific validity of the models, data sources, and assumptions underlying the calculations as well as the role of the co-benefits estimates in the program cost-benefit analysis.

Seawater Intrusion into an Irrigation Well

Full Description

Gradient evaluated the potential for saltwater intrusion into an irrigation well on Cape Cod, MA using site-specific groundwater data, well-specific pumping information, and theoretical calculations.

Risks Associated with Hybrid Vehicle Batteries

Full Description

Gradient reviewed a document describing the potential hazards associated with electric vehicle battery components (and their potential breakdown products), focusing on relevant health effects data and regulatory exposure limits.
