Hydrolic Definition Using Stable Isotope Signatures
The lab will analyze stable isotopes oxygen-18 and deuterium in water samples collected in streams, lakes, wetlands, groundwater, and point sources. This data can identify primary flow sources under varying flow conditions (low to very high flows). Identifying sources can help identify pollutant sources or locate areas that are in need of protection. For example, you may want to protect an area that contributes cold groundwater to a coldwater fishery. Or it could link a water chemistry impairment to a specific source.
