Groundwater sampling is routinely conducted at hundreds of wells at multiple DOE facilities to monitor changes in groundwater quality as a function of time. Some of these wells are very deep (greater than 600 m) which presents unique problems that must be overcome in order to obtain a representative, undisturbed sample. Current technology consists of the use of submersible pumps, bailed samples...

1. Abstract Capture and sequestration of CO2 in deep geological formations is an attractive option to reduce the amount of CO2 emissions into the atmosphere. The capture of CO2 is mostly done at large stationary point sources, such as power plants and refineries, and then it is injected in deep saline aquifers or old oil and gas fields. One of the environmental and policy concerns with this str...

PURPOSE The optimal approach to diagnosing deep venous thrombosis is not entirely clear. In this prospective cohort study, we aimed to evaluate the yield of two methods of assessing the pretest probability of deep venous thrombosis-the treating physician's implicit assessment and the Wells score, a validated prediction rule that incorporates signs, symptoms, and the presence or absence of an al...

there are 3700 wells in tehran city, of which 850 are deep wells. to determine tehran ground water quality, as a pretest we selected 102 wells by simple random sampling; water analyses were made according to the latest edition (1985) of the standard methods. comparisons of the obtained results with who standards show that only 0.98% of the samples go beyond the maximum desirable concentration o...
