Chattahoochee River, Georgia BacteriAlert

Background:   How safe is it to swim, wade, and boat in the Chattahoochee River today? For a highly urbanized river such as the Chattahoochee, much of the answer depends on bacteria levels in the water. This website provides "real time" turbidity data, the estimated Escherichia coli (E coli) bacteria count, the most recent E. coli bacteria counts (sample collected each Thursday), and National...

Surface-Water Quality in Agricultural Watersheds of the North Carolina Coastal Plain Associated with Concentrated Animal Feeding Operations

The effects of concentrated animal feeding operations (CAFOs) on water quality were investigated at 54 agricultural stream sites throughout the North Carolina Coastal Plain during 2012 and 2013.

Three general watershed land-use types were examined during the study, including 18 background watersheds with no active CAFOs, 18 watersheds with one or more active swine CAFOs but no poultry...

Environmental Fate and Transport of Contaminants of Emerging Concern (CEC), South Carolina

The contaminants of emerging concern (CEC) umbrella covers several broad classes of contaminants that include: pharmaceuticals and personal care products, organic wastewater compounds, antimicrobials, antibiotics, animal and human hormones, as well as domestic and industrial detergents. The potential impacts of CECs on the environment, in general, and on natural surface-water and riparian...

Determination of Changes in Water Quality, Streambed Sediment, and Benthic Macroinvertebrates as a Result of Stormwater Runoff from Selected Bridges in South Carolina

Past stormwater monitoring has indicated that bridge deck runoff has relatively high concentrations of a variety of constituents such as nutrients, solids, pesticides, trace metals, and polycyclic aromatic hydrocarbons (PAHs). The objective of this investigation is to quantify the downstream changes in receiving water-quality conditions during periods of observable stormwater runoff from...

Fate and Transport of Pathogens and Nutrients from Land-Applied Animal Manures

This collaborative project between the U.S. Environmental Protection Agency (USEPA) and the USGS was conducted as part of a larger research program being undertaken by USEPA and the U.S Department of Agriculture at several research sites throughout the United States. Goals included:

1. Obtain detailed data concerning the survival of pathogenic microorganisms from manure applied to soil...

Factors Affecting Nitrogen and Phosphorus Loads in Nutrient-Sensitive Water of Eastern North Carolina

Data collected between 1997 and 2008 at 48 stream sites were used to characterize relations between watershed settings and stream nutrient yields throughout central and eastern North Carolina. The focus of the investigation was to identify environmental variables in watersheds that influence nutrient export for supporting the development and prioritization of management strategies for...

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...

Collection and Interpretation of Near Real-Time Surface-Water Quality and Flow Data at Selected Sites in the Waccamaw and Pee Dee River Basins Horry County, South Carolina

This proposed investigation aims to increase the frequency of surface-water quality data collection and initiate stream-flow data collection near existing DHEC ambient sites in Horry County. State-of-the-art water-quality and flow sensors that can collect and report water quality and stream-flow data in near real-time will be installed at 3 sites that are currently on the 303(d) list for SC in...

Application of Phreatophytes to Remediate Contaminated Groundwater Before Discharge to Protected Surface-Water Systems

State environmental agencies are charged with the protection of groundwater and surface-water systems from water-quality degradation. Although the point-source discharge of wastes to surface waters is allowed up to permitted levels, contaminant releases from non-point sources, such as the discharge of contaminated groundwater, is not regulated. A common cause of groundwater contamination is...
