The combination of emerging antibiotic resistance and lack of discovery of new antibiotic
classes poses a threat to future human welfare. Antibiotics are administered to livestock at a …

Travel time distributions are often used to characterize catchment discharge behavior,
catchment vulnerability to pollution and pollutant loads from catchments to downstream …

We identified natural baseline groundwater quality and impacts caused by land use
intensification by relating groundwater chemistry with water age. Tritium, the most direct …

O2 reduction and denitrification rates were determined in shallow aquifers of 12 study areas
representing a wide range in sedimentary environments and climatic conditions. Zero‐and …

Nitrate is one of the most abundant contaminants in groundwater globally, in the United
States, and in California (CA). We studied well construction information, water chemistry …

Nitrate pollution of surface waters is widespread in lowland catchments with intensive
agriculture. For identification of effective nitrate concentration reducing measures the nitrate …

This paper assesses the long-term development in the oxic groundwater nitrate
concentration and nitrogen (N) loss due to intensive farming in Denmark. First, up to 20-year …

Groundwater age is a key aspect of production well vulnerability. Public drinking water
supply wells typically have long screens and are expected to produce a mixture of …

Minerals are the building blocks of clastic sediments and play an important role with respect
to the physico-chemical properties of the sediment and the lithostratigraphy of sediments …

Denitrification driven by pyrite oxidation can play a major role in the removal of nitrate from
groundwater systems. As yet, limited information is available on the interactions between the …
