Groundwater recharge is often difficult to quantify because of its spatial and temporal variability and because of the challenges of measuring it directly. However, recharge estimates are an important component of water budgets developed to accurately assess groundwater availability. For multiple measurements, the apparent ages of the groundwater taken from pumps that are at varying distances from the aquifer outcrop could be a means of verifying flow rate and also indicate situations of over-pumping.For sequential sampling of an individual well every six or twelve months, any changes in the apparent age of the water are plotted versus time.Place a tape seal around the cap/bottle joint to prevent exchange or loss of CO2 from the water.– Please mark the bottle with the appropriate sample identification number in indelible ink or on a non-removable tamper-proof label.– Measure the p H upon collection and send the info to us (not required).– There is no need to refrigerate stored water samples.– Do not add any chemicals to the water upon collection.Studies have shown that storing groundwater for more than 500 days in polypropylene (PP) bottles can induce isotopic effects.
Beta Analytic is offering Oxygen-18 and Deuterium stable isotope measurements for water samples at no additional cost for samples submitted for radiocarbon dating.

Radiocarbon analysis of groundwater can be a monitoring tool to prevent the over-pumping of the aquifer before it becomes contaminated or overexploited.
Contrary to theoretical models and after-the-fact contamination data from chemical analysis, natural level radiocarbon analysis “offers empirical data that can be used” to make decisions on the future of water districts before damage is done.
Groundwater radiocarbon dating is used in combination with the primary measurements of classical hydrological and chemical analyses.
