Emerging organic contaminants in groundwater: A review of sources, fate and occurrence.
Nanogram-microgram per litre concentrations are present in groundwater for a large range of EOCs as well as metabolites and transformation products and under certain conditions may pose a threat to freshwater bodies for decades due to relatively long groundwater residence times. Expand
Review of risk from potential emerging contaminants in UK groundwater.
The routes by which these compounds enter groundwater, their toxicity and potential risks to drinking water and the environment are discussed, and challenges that need to be met are identified to minimise risk to Drinking water and ecosystems. Expand
Emerging contaminants in urban groundwater sources in Africa.
The five-fold increase in median DEET concentration following the onset of the seasonal rains highlights that more mobile compounds can rapidly migrate from the surface to the Aquifer suggesting the aquifer is more vulnerable than previously considered and suggests DEET is potentially useful as a wastewater tracer in Africa.

Uranium occurrence and behaviour in British groundwater
This report describes the concentrations and distributions of uranium (U) in groundwater from aquifers in Great Britain and discusses the most likely sources and controls on U mobility. The reportExpand
Quantification of natural DOM from UV absorption at two wavelengths
Environmental context. Dissolved organic matter (DOM) is part of the global carbon cycle, ecologically and geochemically active, and costly to remove in water treatment. Spectroscopic monitoring at aExpand
In situ tryptophan-like fluorometers: assessing turbidity and temperature effects for freshwater applications.
Findings highlight the potential utility of real time TLF monitoring for a range of environmental applications and in situations where high/variable suspended sediment loads or rapid changes in temperature are anticipated concurrent monitoring of turbidity and temperature is required and site specific calibration is recommended for long term, surface water monitoring.

Using chlorofluorocarbons (CFCs) and sulphur hexafluoride (SF6) to characterise groundwater movement and residence time in a lowland Chalk catchment
Summary Chlorofluorocarbons (CFCs) and sulphur hexafluoride (SF 6 ) provide a technique for dating groundwaters up to 50 years old. When used together, CFCs and SF 6 can help to resolve the extent toExpand
Groundwater quality and depletion in the Indo-Gangetic Basin mapped from in situ observations
Increasing groundwater abstraction in the Indo-Gangetic Basin poses a threat to groundwater supplies. In situ observations reveal that sustainable groundwater in much of the region is limited more byExpand
Persistent and emerging micro-organic contaminants in Chalk groundwater of England and France.
Results from a reconnaissance survey of MOs in Chalk groundwater, including pharmaceuticals, personal care products and pesticides and their transformation products, conducted across the major Chalk aquifers of England and France are presented. Expand
Understanding groundwater, surface water, and hyporheic zone biogeochemical processes in a Chalk catchment using fluorescence properties of dissolved and colloidal organic matter
Understanding groundwater–surface water (GW–SW) interaction in Chalk catchments is complicated by the degree of geological heterogeneity. At this study site, in southern England (United Kingdom),Expand
