Ground Water Seepage and Toxicity Assessment


Inventor: Matt Charette
Serial #: PCT/US2008/010617

Applications: A system to sample, measure, and analyze ground water seepage and seepage rates into bodies of water (e.g. lakes, streams, estuaries). GSM applications include the location of fresh water aquifers, determination and monitoring of ground water toxins, and the validation of ground water remediation efforts. The technology has utility for local and federal regulatory agencies, researchers, and consultants. It can be used in lieu of expensive hydrogeologic investigations or numerical modeling studies, and/or as an independent check on these more traditional techniques.

Technology: Automated groundwater seepage meter (GSM) uses an integrated spectrophotometer for sampling and analyzing both submarine groundwater discharge (SGD) and seawater. GSM produces high-resolution time-series data from tracer dilution data. The system can be configured to quantify water salinity, dissolved nutrients, and/or toxins.  Working prototypes have been developed and field tested.
