“…For East Midlands groundwater Edmunds et al (1982) found most samples had DOC concentrations below their detection limit (0.1 mg/L). DOC in groundwater in the Chalk of Kent ranged from 0.8 to 1.52 except in sites where there was evidence of STWs or contamination from fuels (Lapworth and Gooddy, 2006).…”

“…Facultative anaerobic bacteria can use nitrate as an electron acceptor. As nitrate is depleted, reduction reactions may proceed using other terminal electron acceptors including manganese and iron oxides and sulphate (Edmunds et al, 1982). The organisms that contribute tend to be ubiquitous in surface water, soil and groundwater (Beauchamp et al, 1989) and found at great depths in aquifers (Francis et al, 1989).…”

“…A study of two British aquifers using presence of intermediary species and excess N2 showed relatively little denitrification in the unsaturated zone (Gale et al, 1994). Denitrification can also be substantiated using a mass-balance approach on repeated unsaturated zone core data (Kinniburgh et al, 1999) or by looking at redox changes along a flow line (Edmunds et al, 1982). Microbiological evidence or denitrification potential can also be used.…”

Macronutrient status of UK groundwater: Nitrogen, phosphorus and organic carbon

Groundwater is a large, slowly changing pool of the macronutrients nitrogen (N), phosphorus (P) and dissolved organic carbon (DOC), with impacts on receptors, surface waters, dependent wetlands and coastal marine ecosystems. Sources of N to groundwater include fertilisers, animal wastes and septic led to the reduction observed in rapidly-responding aquifers. For the Chalk, where the unsaturated zone is thick, improvements may not be seen for decades. P is less well-characterised in UK groundwater reflecting the lack of historical interest in groundwater P, although it can be significant in some aquifer matrices.

“…5). Water evolution proceeds from Ca-Mg-HCO 3 to Na-HCO 3 by the evaporation and ion exchange of calcium in the water for the sodium in the soil (Edmunds et al 1982;Edmunds 2003;Zhang et al 2007).…”

The relationship between and evolution of surface water and groundwater in Songnen Plain, Northeast China

To improve water management, the relation and the hydrochemical evolution of surface water and groundwater were studied in the Songnen Plain. The surface water and groundwater samples were evaluated for stable isotopes and hydrochemistry analyses. The stable isotopic compositions (d 18 O, d D) indicate the groundwater recharges from the precipitation. However, the connectivity between surface water and groundwater is weak, because of the clay layer and the interrupted aquifer. The water evolution is from Ca-Mg-HCO 3 to Na-HCO 3 by the evaporation, water-rock interaction, and ion exchange processes. The water evaporation and leaching of salinealkaline soil are the main reasons for water salinity. Further, the leaching of salts in the soil during recharging from backwater and irrigation water intensifies the salinization. The relationship between and evolution of surface water and groundwater provide important guidance for water management not only in the arid and semi-arid area, but also in the soda saline-alkali soil regions of the world.

“…The hydrogeochemistry of groundwater is influenced by many factors, including the mineralogy of aquifers, the chemical composition of rainfall and surface water, climate, topography, and anthropogenic activities 5) . Thus, the hydrogeochemical interpretation of the groundwater quality analyses of representative water samples can provide useful information on the geochemical processes hydrodynamics, origin of groundwater, and interaction of the groundwater with the aquifer materials.…”

The groundwater in the Pleistocene confined aquifer (PCA) of the Red River Delta (RRD) was examined using self-organizing map (SOM) and Gibbs diagrams to determine, for the first time, its spatial classifications in terms of its hydrogeochemical characteristics. In this study, the groundwater chemistry dataset used in the analysis is composed of 8 major dissolved ions (i.e. Ca ) that are consistently found in 52 groundwater monitoring wells within the study area. Based on the results, the groundwater in the PCA monitoring wells of the delta can be classified into 2 major water types: high and low salinity. Each water type is composed of cluster-types that have similar hydrogeochemical characteristics. The high salinity water type has 2 clusters (or sub-types), while the low salinity (or fresh water) has 4. From the Gibbs diagrams, results indicate that the high salinity in the groundwater is mostly influenced by either (or both) anthropogenic activities and salt water intrusion.
