Abstract Water from 72 domestic wells in northeast Ohio was examined to determine the nature and extent of variation in fluoride content. The sedimentary terrain of about 230km 2 includes aquifers characterized as unconsolidated sediments, shales, and sandstones.

Derivatives of dicyclopentadiene in ground water
Biological Mass Spectrometry, 1987Dicyclopentadiene, a waste product of manufacturing at the Rocky Mountain Arsenal near Denver Colorado, has been detected in ground water at this facility. Ground water extracts were analysed by gas chromatography-mass spectrometry (GC/MS) to determine if derivatives of dicyclopentadiene were present in addition to dicyclopentadiene and other chemical ...

Science, 1961
Tritium in Arabian rainfall has followed the trend observed in North America with peaks in 1958 and the spring of 1959. These measurements will be useful for future hydrologic studies. Water from wadi gravels averages 10 yr old. Carbon-14 measurements of deep waters indicate ages of several thousand years.

Nitrates in Wisconsin Ground Water
Environmental Letters, 1975Nitrate analyses were performed on ground water well samples originating from sources throughout Wisconsin. The data ranged from below the analytical detection limit up to 140 mg NO3-N/1. Over nine percent of all wells sampled has nitrate concentrations in excess of 10 mg NO3-N/1.

Abstract Heat carried by ground water serves as a tracer to identify surface water infiltration, flow through fractures, and flow patterns in ground water basins. Temperature measurements can be analyzed for recharge and discharge rates, the effects of surface warming, interchange with surface water, hydraulic conductivity of ...
