Much of his practicalexperience includes work at sites with commingled multisource plumes,vapor intrusion concerns, and property development.

DWR is also tasked with evaluating groundwater sustainability plans for adequacy. Agencies that have ongoing successful groundwater management programs that are managed to a sustainable yield can be exempted if they meet the requirements in the alternatives section of the Groundwater Sustainability Plan regulations.

However, estimates of groundwater re-charge via isotope analyses can provide critical information regards rates of groundwater re-charge and discharge. Traditionally, management of water resources has focused on surface water or groundwater as if they were separate entities.

What is Radiocarbon Dating? Many of the ideas and resources developed for investors interested in water risk integration can be found at www.

Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone. Debatably, Antarctic melting is too often used as the catch-all fudge factor to explain the unexplainable.

Any precipitation or glacial meltwater flowing into an endorheic basin could require centuries to thousands of years to flow back to the oceans. Moosdorf has reviewed the locations and many human uses of fresh submarine groundwater discharge around the world. His background includes extensive research and applications of isotopes ranging from groundwaters in arid regions to temperate climates.

Cartwright has authored approximately articles, written several book chapters, presented more than lectures in conferences around the world, and isthe recipient of several patents.

Bonte, Matthijs Matthijs Bonte, Ph. He plays a prominent role in ASR projects involving both injection wells and land spreading recharge methods, and currently is the lead hydrogeologist for the OASIS program — an ASR project with the goal of annually injecting and recovering 30, acre-feet of potable water from a single wellfield.
