2008 article

Nitrate Contamination in Groundwater on an Urbanized Dairy Farm

Showers, W. J., Genna, B., McDade, T., Bolich, R., & Fountain, J. C. (2008, May 30). Environmental Science & Technology.

By: W. Showers n, B. Genna n, T. McDade n, R. Bolich n & J. Fountain n

MeSH headings : Bromides / analysis; Chlorides / analysis; Dairying; Environmental Monitoring / statistics & numerical data; Flow Injection Analysis; Magnetics; Nitrates / analysis; Nitrogen Isotopes / analysis; North Carolina; Urban Renewal; Water Pollutants, Chemical / analysis; Water Supply / analysis
topics (OpenAlex): Groundwater and Isotope Geochemistry; Groundwater flow and contamination studies; Urban Stormwater Management Solutions
TL;DR: The isotope and Cl/Br ratios indicate that nitrate contamination in these drinking wells are not from septic systems, but are the result of animal waste leached from pastures into groundwater during 35 years of dairy operations which did not violate any existing regulations.

2006 article

The effect of changes in surface wettability on two-phase saturated flow in horizontal replicas of single natural fractures

Bergslien, E., & Fountain, J. (2006, August 25). Journal of Contaminant Hydrology.

By: E. Bergslien * & J. Fountain*

author keywords: multiphase flow; non-aqueous phase liquids; NAPL; fracture flow; fracture modeling
MeSH headings : Epoxy Resins / chemistry; Geological Phenomena; Geology; Models, Theoretical; Polystyrenes / chemistry; Surface Properties; Surface-Active Agents / chemistry; Thermodynamics; Water / chemistry; Water Movements; Water Pollutants, Chemical / chemistry; Wettability
topics (OpenAlex): Hydraulic Fracturing and Reservoir Analysis; Groundwater flow and contamination studies; Enhanced Oil Recovery Techniques
TL;DR: Detailed characterization of epoxy reveals that it is not a sufficiently good analogue to natural rock for many two-phase flow studies, and there was generally good agreement between theoretically calculated Young-Laplace aperture invasion boundaries and the observed minimum apertures invaded.

Nitrate Movement in Shallow Ground Water from Swine‐Lagoon‐Effluent Spray Fields Managed under Current Application Regulations

Israel, D. W., Showers, W. J., Fountain, M., & Fountain, J. (2005, September 1). Journal of Environmental Quality.

By: D. Israel n, W. Showers n, M. Fountain n & J. Fountain n

MeSH headings : Animals; Environmental Monitoring / legislation & jurisprudence; Environmental Monitoring / statistics & numerical data; Fresh Water / chemistry; Manure / analysis; Nitrates / analysis; Nitrogen Isotopes / analysis; North Carolina; Oxygen Isotopes / analysis; Sus scrofa; Water Movements; Water Pollutants, Chemical / analysis
topics (OpenAlex): Soil and Water Nutrient Dynamics; Hydrology and Watershed Management Studies
TL;DR: Measurement of delta18O and delta15N enrichment of nitrate in ground water throughout the WAF-riparian system indicated that denitrification has not caused significant 15N enrichment and delivery of some waste-derived nitrate N to the stream in shallow ground water. (via Semantic Scholar)
