Surface Nuclear Magnetic Resonance Experiments To Detect Subsurface Water At Haddam Meadows, Connecticut

Nuclear magnetic resonance (NMR) techniques have been adapted to surface<br>geophysical prospecting by scientists at the Institute of Chemical Kinetics and Combustion,<br>Novosibirsk, in Russia. The first tests of this method in the U.S. were conducted in the summer<br>of 1993 through a joint collaboration between the U.S. Geological Survey; the U.S.<br>Environmental Protection Agency; the Institute of Chemical Kinetics and Combustion,<br>Novosibirsk, Russia; and Firm Hydrogeotom, Moscow, Russia. NMR “soundings” were<br>conducted at 10 sites throughout the U.S. The results from Haddam Meadows State Park,<br>Connecticut, are reported here. They are of interest, in part, because Haddam Meadows was<br>found to be a “high noise” site for the NMR soundings but is considered to be a fairly typical<br>site; in terms of noise, for urban and many rural areas.
