2008 An Environmental Crossroads

Global warming clouds our future. Pollution degrades our air, soil and water. Environmental toxins compromise the health of our children. Misuse threatens the sustainability of our forests, fisheries, wetlands and coasts, and the health of species that live there.

But there is reason for hope.

Through sound science and policy research, we're finding answers to these problems. Airborne lead and acid rain have been dramatically reduced. Industrial water pollution has decreased. Habitats are being preserved.

Faculty members from the Nicholas School of the Environment and Earth Sciences at Duke University are part of the effort to help find these answers and establish new environmental practices and policies to safeguard our natural resources for generations to come.

Water Quality
Water quality presents a broad range of challenges in the Treasure State. In the eastern part of the state naturally saline groundwater, saline seep and the potential effects of coal bed methane development are the top concerns. More than a century of metal mining and smelting have compromised water quality in many western Montana watersheds. Statewide, there is growing concern about the effects of non-point source water pollution from natural processes and human land uses.

David Hinton studies the causes and effects of environmental contaminants on ecosystem health, particularly on fish. He has bred a strain of guppy-like Medaka fish that are highly sensitive to contaminants and can be used as sentinels to detect water quality problems in urban drinking water.

Research focus: Mechanistic and integrative understanding of the manner in which environmental contaminants exert their effects. Pathobiology and toxiopathology of persistent environmental contaminants in fishes. Deciphering deleterious effects and establishing causal linkages.

Some of Hinton’s specially bred Medaka sentinel fish have been sent to Orange County, Calif., where they are being use to evaluate the safety of its drinking water. Any hints of lesions on or in their tiny bodies may hint of unseen toxic agents.

Kenneth Reckhow is director of the Center for the Analysis and Prediction of River Basin Environmental Systems.

Research focus: Reckhow is a policy expert on water quality assessment and management, risk assessment, water quality modeling and decision analysis.

Recent work by Reckhow and his research team has focused on the assessment of nonpoint source pollution on surface water quality and the development of "Total Maximum Daily Loads" (TMDLs). Reckhow was recently chair of the National Academy of Sciences Committee assessing the scientific basis of the EPA TMDL program.
