Water quality issues in Madison County and the surrounding regions of North Carolina.
The effect of acid deposition on aquatic systems has been the subject of intensive research for many years. However, the vast majority of this research has focused on the impact of acid deposition on poorly buffered lakes in which the lake water pH decreased dramatically altering aquatic life. Eutrophication is caused by extensive plant growth generally as a result of increased nitrate and phosphate concentrations. Nitrate concentrations are often elevated in acid rain. Although phosphate does not contribute to acid rain it may be associated with particulate matter from similar pollution sources. pH and a low acid neutralizing capacity (ANC), also called alkalinity, are used as the primary indicators for acid deposition impact on surface water bodies. However, many buffered lakes within the mid-western and eastern U.S. may be affected by acid deposition through eutrophication, but without a significant decrease in pH. Nutrient concentrations in Pine Lake water as well as in wet and dry deposition to the Pine Lake watershed were monitored in order to determine if background atmospheric inputs from acid deposition contributed sufficient nutrients to promote eutrophication. Pine Lake, located near Oneonta, NY, has had few anthropogenic sources of nitrates and phosphates because Hartwick College owned the majority of the Pine Lake watershed.
Complex biological, geochemical, hydrological, and chemical processes control subsurface contaminant transport. Many aspects of these processes have been, and are currently being, studied mechanistically at the laboratory scale. In order to describe the interrelationships between these different processes under more realistic field scale heterogeneities, field scale tests are required. I was part of a multi-disciplinary team of scientists who designed and implemented integrated laboratory and field scale adsorption, aquifer pumping, and infiltration tests. These tests helped quantitate the significance of preferential flow under both saturated and unsaturated conditions, quantitate the extent of adsorption equilibrium under field conditions, and evaluate the applicability of laboratory measured parameter values in describing contaminant transport in the field.
Colloids may sorb significant quantities of pollutants due to their large surface areas relative to their mass. The fate of colloids, and pollutants sorbed to colloids, is a function of their size distribution, morphology, and composition, as well as the chemistry and flow patterns of the water body. A series of fractionation steps and analytical procedures were developed to non-destructively characterize colloids in the Rhine River. This data was used with current coagulation-sedimentation models to evaluate the processes controlling the colloidal concentration and size distribution and to predict the fate of colloids and colloid-associated pollutants in the Rhine River.
Association of groundwater contaminants with mobile colloids may result in more rapid contaminant transport than predicted by current models. In order to more accurately estimate the risk to human health resulting from groundwater contamination, colloid-associated contaminant transport was considered. Laboratory column studies demonstrated that alterations in groundwater chemistry could result in the mobilization and subsequent transport of colloids. This work demonstrated that the effects of solution chemistry on colloid mobilization and transport must be considered in designing waste disposal and treatment processes because most contaminant inputs to groundwater can alter the solution chemistry.
Mercury concentrations in soil/sediment, water, and fish tissue were determined before, during, and after the construction of Richard B. Russell Reservoir, a lake on the Savannah River, in order to test the hypothesis that natural background levels of mercury in soil can be mobilized through microbial methylation into the waters of newly impounded reservoirs leading to elevated mercury concentrations in edible fish. Measured increases in the mercury concentration of fish tissue and changes in mercury speciation from primarily inorganic to primarily organic forms supported this hypothesis.
