Design And Evaluation Of A Modified In Situ Mesocosm To Study Denitrification In The Karlsruhe Aquifer, Jason M. Warne
Theses and Dissertations
To simplify the in situ mesocosm (ISM) design given in Schlag (1999), a modified ISM was designed and built in which a 6-inch long sand point replaces three 16-inch diameter screens. The modified design also includes an optional submersible pump mounted on top of the ISM chamber, making it capable of applications at depths greater than those attainable using a peristaltic pump from the ground surface. Two ISMs, one the original design (0-ISM) and the other the modified design (M-ISM) with an optional submersible pump, were installed in the Karlsruhe aquifer, near Minot, ND, in late June, 2003.
