The unit resembles a large snare drum. A port is positioned in the center for attaching the removable volume collection bag. These kinds of units are designed for insertion into sediment which is the application in all previously published seepage studies. The second design, for installation on hard rock surfaces, consists of a sheet of clear vinyl plastic cemented directly to the rock with hydraulic cement. A port for the volume collection bag is attached to the center.
Net outflow is channeled into the volume collection bag.
Preliminary results indicate that seeping groundwater may replace all of the water in eastern Florida Bay in less than 1 year. This information has not been incorporated in any hydraulic modeling attempts. The study has also been featured on PBS television. 1997 - Expertise in carbonate sedimentology, survey and sampling techniques, coring, well installation, boat operations, diving, GPS, Nutrient analyses, Flurometer analysis, strong backs and portland cement mixing capability. 1999 - Ability to synthese results into a final report, articles and presentations.
