Effects of Land-Applied Biosolids on Water Quality in the Jordan Lake Watershed, North Carolina

Land application of municipal wastewater biosolids is the most common method of biosolids management used in North Carolina and the United States. Biosolids have characteristics that may be beneficial to soil and plants. Land application can take advantage of these beneficial qualities, whereas disposal in landfills or incineration poses no beneficial use of the waste.

However, recent...

Brunswick County, NC Groundwater-Level Monitoring

Since 2000, the population of Brunswick County has grown by more than 50%. A growth of this magnitude places significant stress on Brunswick County’s natural resources. County planners have recognized the potential consequences of land use changes associated with growth and the resulting increased demand on water resources by consolidating the many public utility providers into one...

West Indian Manatee Population Genetics

Nuclear microsatellite markers have been developed and implemented on ~2,000 West Indian manatees. These markers provide individual genetic fingerprints for mark-recapture studies, population structure information for the conservation of unique or isolated populations, and pedigree and relatedness information for addressing inbreeding and breeding structure patterns.
