This paper identifies methods that can be used by water supply managers to assess and manage the risks associated with raw water quality. The process begins with risk assessment, a tool used for assessing the sources of ...

The sodium hydroxide, sodium silicate, polyphosphate, and zinc-orthophosphate have been assessed for their effectiveness for corrosion inhibition in drinking water supply of the City of Thunder Bay. The data for each water ...

An interactive river water quality model has been developed for simulating the fate and transport of pollutants through a river system using C++ on a microcomputer. At present, it helps a user predict the variation of BOD, ...

The most common approach used to model the transport of solutes in the subsurface is a mass balance partial differential equations, which combines two terms, viz., ( i ) solute displacement by convection with the mean ...

The emerging problem of groundwater contamination due to agricultural land use changes with increased use of fertilizers and pesticides has created a need for information which can be supplied by properly designed groundwater ...

There are around 50 seafood processing industries located in Tamilnadu and 10 industries near Chennai. All these industries are located near the seacoast and thereby discharging their effluents into the sea and thus polluting ...

Dissolved oxygen (DO) is an important parameter indicating the health of the stream. There is a continual utilization (deoxygenation) and/or replenishment (reaeration) of dissolved oxygen due to the influx of waste load ...

The land disposal of solid wastes creates an important source of groundwater pollution. A land fill may be defined as any land area serving as a depository of urban, or municipal, solid waste. Leachate from a landfill can ...

The present study objectively analyzes the state of water quality (in terms of DO-BOD) in the Kanpur stretch of river Ganga and assesses the non-point sources and their impact by employing water quality modeling. The ...

In an attempt to evaluate the impact of irrigation on the environmental geochemistry of ground water 136 samples from Sangamner area were analyzed. The chemical characteristics of ground water have been found to be dominated ...
