TL;DR: 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.

TL;DR: 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.

TL;DR: 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.

TL;DR: The vadose zone is an important store of nitrate that should be considered in future budgets for effective policymaking, and it is argued that in these areas use of conventional nitrogen budget approaches is inappropriate.

TL;DR: The authors reviewed the impact of anthropogenic climate change on water in the UK and looked at projections of future change, concluding that future changes in rainfall and evapotranspiration could lead to changed flow regimes and impacts on water quality, aquatic ecosystems and water availability.
