Physico-chemical data of open field precipitations collected at the meteorological station AH located at the top of the Strengbach catchment. A sample is taken every fortnight for laboratory analysis. Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l) and molar concentrations of Na+, K+, Ca2+, Mg2+, NH4+, Cl-, NO3- and SO42- (µmol/l).

Physico-chemical data for stream water from the Strengbach watershed outlet. A sample is taken every fortnight for laboratory analysis. Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l), Dissolved Organic Carbon DOC, alkalinity and molar concentrations of Na+, K+, Ca2+, Mg2+, Cl-, NO3-, SO42- and Si - (µmol/l).

Physico-chemical data for spring water from the Strengbach catchment area. Four springs are collected in a spring collector containing a mixing basin. This underground spring collector collects four independent springs: CS1, CS2, CS3 and CS4 and a spring mixture: CR. The spring mix CR contributes to the drinking water supply of the village of Aubure (68, France). Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l), Dissolved Organic Carbon DOC, alkalinity and molar concentrations of Na+, K+, Ca2+, Mg2+, Cl-, NO3-, SO42- and Si - (µmol/l). The CR spring is sampled every two weeks, while the four sources CS1, CS2, CS3 and CS4 are sampled less frequently (6 to 8 weeks depending on the period).
