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: In this article, the authors report new evidence from high-resolution in situ records of groundwater levels, abstraction and groundwater quality, which reveal that sustainable groundwater supplies are constrained more by extensive contamination than depletion.

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: A comprehensive assessment of the water quality status, both microbial and chemical, of urban groundwater in SSA across a range of hydrogeological terrains and different groundwater point types is provided.
