The oldest sedimentary and metasedimentary rocks exposed

This study was different from previous contingent valuation studies in that it used water rights as the payment vehicles instead of dollars -...
The lack of cost-effective, reliable sampling methods for many wetland
characteristics hinders efforts to describe the structural and functional
properties of wetlands. This study evaluated techniques for sampling the
subsurface hydrology and invertebrates of freshwater wetlands. The depth of
rusting on mild steel rods was compared with water well measurements...
