North Temperate Lakes LTER: Groundwater Chemistry 1984 - current

Water chemistry is measured annually in 11 monitoring wells to characterize regional
groundwater chemistry in the Trout Lake area. The chemical parameters measured include pH,
conductivity, total alkalinity, disolved inorganic and organic carbon, total nitrogen,
nitrae, ammonia, total phosphorus, calcium, magnesium, soium, potassium, chloride, sulfate,
iron, manganese, total silica and dissolved reactive silica. Chemical data areavailable at a
quarterly sampling frequency for some years. In addition (see related data set - Groundwater
Level), water levels in 37 monitoring wells are measured several times per year. The wells
are scattered throughout the Trout Lake hydrological basin and the data are used to
calibrate and test regional groundwater flow models. Sampling Frequency: annually - with
some earlier data from quarterly sampling Number of sites: 11
