Strontium Isotopic Ratios of Water
Strontium isotopic ratios (87Sr/86Sr) can be used to detect and trace groundwater sources and interactions with local geology, influenced by the flow path and rate of water underground. Sr isotopes can identify the mixing between different water bodies, changes in watershed histories, specify nutrient pathways, determine groundwater determination, and pinpoint the sources of salinity within freshwater systems.
Water – 125 mL: Use any type of small-neck plastic bottle (HDPE, LDPE, PP) to collect your sample. Prior to collection, rinse the bottle with the running sample water. Do not add any chemicals to the water, do not acidify the water. Fill the bottle all the way, but keep the neck of the bottle empty to allow for any necessary expansion during shipment. Please put the bottles inside a plastic bag and seal the bag with a zip-tie or duct tape. Clearly label both the bottle and the plastic bag.
