Nitrogen contamination of surficial aquifers - A growing legacy Nitrogen contamination of surficial aquifers - A growing legacy
The virtual ubiquity of fertilizer-fed agriculture, increasing over several decades, has become necessary to support the global human population. Ironically, widespread use of nitrogen (N) has contaminated another vital resource: surficial fresh groundwater. Further, as nitrous oxide (N2O) is a potent greenhouse gas, anthropogenic manipulation of N budgets has ramifications that can...

The influence of nutrients and physical habitat in regulating algal biomass in agricultural streams The influence of nutrients and physical habitat in regulating algal biomass in agricultural streams
This study examined the relative influence of nutrients (nitrogen and phosphorus) and habitat on algal biomass in five agricultural regions of the United States. Sites were selected to capture a range of nutrient conditions, with 136 sites distributed over five study areas. Samples were collected in either 2003 or 2004, and analyzed for nutrients (nitrogen and phosphorous) and algal...

Trends and transformation of nutrients and pesticides in a Coastal Plain aquifer system, United States Trends and transformation of nutrients and pesticides in a Coastal Plain aquifer system, United States
Four local-scale sites in areas with similar corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] agriculture were studied to determine the effects of different hydrogeologic settings of the Northern Atlantic Coastal Plain (NACP) on the transport of nutrients and pesticides in groundwater. Settings ranged from predominantly well-drained soils overlying thick, sandy surficial aquifers...

Identifying pathways and processes affecting nitrate and orthophosphate inputs to streams in agricultural watersheds Identifying pathways and processes affecting nitrate and orthophosphate inputs to streams in agricultural watersheds
Understanding nutrient pathways to streams will improve nutrient management strategies and estimates of the time lag between when changes in land use practices occur and when water quality effects that result from these changes are observed. Nitrate and orthophosphate (OP) concentrations in several environmental compartments were examined in watersheds having a range of base flow index...

Whole-stream response to nitrate loading in three streams draining agricultural landscapes Whole-stream response to nitrate loading in three streams draining agricultural landscapes
Physical, chemical, hydrologic, and biologic factors affecting nitrate (NO3 −) removal were evaluated in three agricultural streams draining orchard/dairy and row crop settings. Using 3-d “snapshots” during biotically active periods, we estimated reach-level NO3 − sources, NO3 − mass balance, in-stream processing (nitrification, denitrification, and NO3 − uptake), and NO3 − retention...

Linking ground-water age and chemistry data along flow paths: Implications for trends and transformations of nitrate and pesticides Linking ground-water age and chemistry data along flow paths: Implications for trends and transformations of nitrate and pesticides
Tracer-based ground-water ages, along with the concentrations of pesticides, nitrogen species, and other redox-active constituents, were used to evaluate the trends and transformations of agricultural chemicals along flow paths in diverse hydrogeologic settings. A range of conditions affecting the transformation of nitrate and pesticides (e.g., thickness of unsaturated zone, redox...
