Allow the well water to flush out the inside of the bottle thoroughly and then dump the contents prior to refilling.4.Fill the bottle with as little head space as possible but leave the neck of the bottle empty to allow for any expansion during shipment.5.
Please use a box with sufficient packing to prevent breakage during shipment.
We recommend commercial courier or registered first-class mail when sending the samples to the lab.
"That opens up completely new application horizons.
The need for such analyses is great, especially in the field of tracer oceanography," explains Prof. Markus Oberthaler conducts research at the Kirchhoff Institute for Physics, Werner Aeschbach at the Institute of Environmental Physics. Aeschbach is also Director of the Heidelberg Center for the Environment (HCE).
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.This isotope is useful for determining age in the range of 50 to 1,000 years. Dr Markus Oberthaler of the Kirchhoff Institute for Physics and Prof.Dr Werner Aeschbach of the Institute of Environmental Physics of Heidelberg University will direct the three-year project.Please email the courier and tracking number so we can monitor your package.Radiocarbon analysis of groundwater can be a monitoring tool to prevent the over-pumping of the aquifer before it becomes contaminated or overexploited.Before placing the bottles in a sturdy cardboard box, please put the bottles inside a plastic bag and seal the bag with a zip-tie or duct tape.
