Overview

    This program brings the basic sciences to bear on many crucial concerns about the environment. The environmental matters of particular interest revolve around ecosystems and our land and water resources. Specific concerns include ecosystem services, environmental protection, land-use planning, waste management, ground- and surface-water quality, reclamation and remediation of disturbed or contaminated sites, and minimizing agricultural and other human impacts on the environment.

    The environmental science curriculum is multidisciplinary and strongly science and technology oriented. The basic sciences and computational skills are at the core of each of the major's four options, but specific requirements make each option unique. The curriculum prepares one for immediate entry into environmental careers, as well as for graduate specializations. The environmental job market is quite strong, with a shortage of qualified individuals in the field.

    The four concentrations, or curricular options, within the major and some of the career opportunities associated with each are as follows:

Aquatic Resources Option

    The emphasis in this option is on fresh water. Both surface- and ground-water quality become degraded as a result of human activities. Those processes, their consequences, and solutions are the focus of this option. Students in this option are entering careers in the areas of regulation, remediation, and environmental protection.

Land Resources Option

    This option develops an understanding of many of the complex biological, chemical, economic, geological, and soil factors that must enter into good decisions on land use. The graduates in this option find employment with various governmental agencies and in the private sector.

Plant Resources Option

    Plants are used in a variety of ways to solve environmental problems. Reclamation of disturbed areas often involves establishing vegetation. Plants are important components of wetlands, which provide a number of important environmental functions. Plants may also be used to remove pollutants from the soil or water. This option provides a track for students seeking environmental careers that build on their interest in plants.

Waste Management Option

    Our "throw-away society" has begun to feel many of the consequences of that ethic. This option deals not only with environmental cleanup and safe disposal but also with waste minimization, recycling, and other alternatives. Graduates find opportunities in regulatory agencies as well as in the private sector. The reclamation industry is a major employer, as are manufacturers and municipalities that must comply with waste management laws.

Opportunities to Excel

    Students with outstanding records can qualify for the Honors Program and graduate "in honors" in environmental science. Other opportunities for personal and professional growth and for recognition include the department-sponsored Environmental Student Organization, membership in Alpha Zeta and other honoraries, and several scholarships designated for majors. Faculty members work with undergraduates on a variety of environmental research projects. Many employers seek environmental science majors for internship and co-op positions.
