Water Quality in Walnut Creek Watershed: Nitrate-Nitrogen in Soils, Subsurface Drainage Water, and Shallow Groundwater
Nonpoint source contamination of surface and groundwater resources with nitrate-N (NO3-N) has been linked to agriculture across the midwestern USA. A 4-yr study was conducted to assess the extent of NO3-N leaching in a central Iowa field. Water flow rate was monitored continuously and data were stored on an internal datalogger. Water samples for chemical analysis were collected weekly provided ...
متن کاملMicrobial Nitrate Processing in Shallow Groundwater in a Riparian Forest
We measured denitrification, immobilization, and respiration in microcosms that simulated groundwater conditions in a riparian forest in Rhode Island. Measured rates were compared with rates of NOj" removal measured in a companion study using a groundwater monitoring well network and 10-mo injection of NOf and a bromide tracer to groundwater in the same riparian forest. Limiting factors for den...
متن کاملFactors Affecting Nitrate Distribution in Shallow 6 Groundwater under a Beef Farm in South Eastern Ireland
18 Groundwater contamination was characterised using a methodology which combines 19 shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a 20 statistical framework and hydrogeological techniques. Nitrate-N (NO3-N) 21 contaminant mass flux was calculated across three control planes (rows of 22 piezometers) in six isolated plots. Results showed natural attenuation occu...
