The development of a conceptual site model (CSM) is an invaluable tool used for assessing and planning remedial actions at a contaminated site. The CSM incorporates site-specific, hydrogeologic and geochemical information to identify contaminants of concern, sources of pollution, environmental...

A multi-layered three-dimensional hydrodynamic model has been developed to provide flow fields and water level changes in Hamilton Harbour. The field data collected in Hamilton Harbour during 1990 & 1991 field seasons was used for model verification. The simulated currents were compared with current...

The problem of the passive contaminant spreading in a steady viscous fluid stream is discussed while the admixture's dissipation and diffusion are taken into account. The channel is assumed to be a horizontal plane, curvilinear and quite lengthy, so that the ratio of the stream width to its length...

The present studies aimed to obtain clean fuel combustion and get detailed information about the processes that determine the electric field effect on NOx formation in flame channel flows. The experimental studies demonstrate that the interaction between the radial electric field and the flame...

Fire agencies worldwide apply millions of gallons of fire suppression chemicals on a broad array of ecosystems. These chemicals are considered to have minimal effects on the health of people who might be exposed to them. Only incidents of skin and eye irritation have been reported as a result of...

The efficacy of low cost adsorbing materials for removal of 2,4-D (2,4 dichloro phenoxy acetic acid) and atrazine (2-chloro-4-ethyamino-6-isopropylamino-1,3,5 triazine) herbicides from drinking water was evaluated. Five low cost adsorbents, viz. wood charcoal, rubber granules, bottom ash, macro...

During the production of cephradine (a main constituent of anti-osmotic drug) a large quantity of concentrated effluent was produced. The main polluting compounds in this effluent are osmotic drug, acetic acid and ammonia. The main objectives of the study were to assess the toxicity in terms of...
