Abstract:

Greenfield Lake in Wilmington, North Carolina has experienced recent problems with algal blooms, low dissolved oxygen levels, and fish kills. Many of these issues have likely been caused by high nutrient loading. This study examined lake sediment as a source and sink for phosphorus, the nutrient most often responsible for freshwater eutrophication.

Abstract:

Cooperation between the New Zealand government and the pork industry resulted in more effective swine waste management practices. Consideration of such practices could provide ways to improve hog waste management in the state.

Abstract:

Drainage features, such as natural streams and man-made ditches, provide pathways for nutrients and other materials from land to surface waters. The authors compared agricultural areas with other land cover types as sources of sediment-associated phosphorus in drainage features. Sample sites were chosen to include roadside ditches along agricultural fields, near livestock operations, residential areas, forested and other undeveloped areas. Several natural streams were also selected. Results indicate that agricultural activities can contribute significantly to sediment phosphorus loads in drainage features.

Abstract:

This study of the chemical weathering of the limestone outcropping on the north shore of Lake Waccamaw indicates that the process plays an important role in neutralizing the relatively acidic source waters and maintaining the lake's high alkalinity.
