Hydrogeology Field Camp
The Hydrogeology Field Camp is a capstone experience for undergraduate degrees in geology, and it can be a great opportunity for graduate students to learn new skills. There is a summer field camp that focuses on teaching topics and field skills in hydrogeology. The camp is designed to give the student a working knowledge of the methods and concepts of field hydrogeology, and to provide the opportunity to use those methods in several hydrogeologic settings. The course is led by instructors from Clemson, but many practicing geologists, hydrogeologists, and scientists from other universities, the USGS, and consulting companies also lead trips and exercises in their particular expertise.

The Hydrogeology Symposium is an annual symposium featuring oral and poster presentations covering a wide range of topics including Contaminant Transport, Remediation, Numerical Modeling, Characterization, Watershed Hydrology, Engineering Geology, GIS and Remote Sensing, Geophysics, Geochemistry, Stratigraphy, and Regulatory Issues. Everyone is encouraged to submit an abstract and give a presentation of his/her work.

A Greenhouse Gas Emissions Calculation Tool for Water Utilities
The issue of climate change has led to an increased emphasis on sustainable practices in almost every facet of our lives. For water utilities, this has increased scrutiny on energy use. Although traditionally viewed solely in financial terms, energy use is also the primary source of greenhouse gas (GHG) emissions from water utilities. The emerging concern over GHG emissions coincides with potential federal legislation and regulation by the Environmental Protection Agency (EPA). In order for water utilities to determine their GHG emissions, guides and tools must be made readily available. Information to educate water utilities about their GHG emissions is often scattered and calculation tools are not publically available for utilities in the United States.
The main objective of this research was to develop an accounting tool to facilitate water utilities in calculating their GHG emissions. This tool will allow a water utility to create a GHG emissions baseline and assist in meeting any emissions reduction goals. More specifically, this research project focused on four sub-objectives: (i) to create an Excel-based program to serve as the shell of the GHG emissions accounting tool, (ii) to develop energy prediction equations for different portions of the water production process, (iii) to include the water-energy nexus in the accounting tool, and (iv) to test the program using real data at various water utilities.

REMChlor (Remediation Evaluation Model for Chlorinated Solvents) is an analytical solution for simulating the transient effects of groundwater source and plume remediation. In the analytical method, the contaminant source model is based on a power function relationship between source mass and source discharge, and it can consider partial source remediation at any time after the initial release. The source model serves as a time-dependent mass flux boundary condition to the analytical plume model, where flow is assumed to be one-dimensional. The plume model simulates first order sequential decay and production of several species, and the decay rates and parent/daughter yield coefficients are variable functions of time and distance. This approach allows for flexible simulation of enhanced plume degradation that may be temporary, limited in space, and which may have different effects on different contaminant species in the decay chain. Cancer risks posed by carcinogenic species in the plume are calculated assuming that the contaminated water is used in a house for drinking, bathing, and other household uses.http://www.epa.gov/ada/csmos/models/remchlor.html
Aerated Lagoon Technology Technical Notes
Aerated lagoon technology, especially that of high-performance systems, is one of the most misunderstood technology in wastewater treatment. This misunderstanding is largely the result of its evolution from the technology of facultative lagoons, in which algae play a vital role and hydraulic retention times are long. In fact, the technology of high-performance aerated lagoons has much in common with that of activated sludge. With proper design and operation, aerated lagoons can deliver effluents that meet limits of 30 mg/L, both for TSS and CBOD5. Furthermore, with modification or with the addition of low-tech process units, they can be designed to nitrify. The major advantages of aerated lagoon systems are their low cost and their minimal need for operator attention.
The performance of aerated lagoon systems, as well as the diagnosis and remedies of their operational problems, is the focus of a series of technical notes that should be of considerable value both to engineers and operators. The development of the technical notes will be a continuing activity on the part of the author and will be added to the pdf document found here. Download PDF
This program is provided free of charge to foster a better understanding of single sludge processes of wastewater treatment. [More]
The EEES Department offers a number of professional development opportunities for K-12 educators. Teachers can sign up to take graduate classes or attend workshops and field trips with the like-minded teaching professionals. They can use units from the South Carolina Studies Program, the Southeast MAPS Program, or other curriculum supplements with their classes. They can also find links to a variety of other geoscience and environmental education resources for the classroom.See the Geology K-12 Outreach Program web site for more information.
