Research areas

Shiv Prasher works on ground water pollution and ground water movements. He is especially interested in agricultural pollution by pesticides and nitrates, field measurement, and modelisation. He also works to develop on-farm pollution control systems.

 
Previous environmental projects

Person(s) in charge : Prasher, Shiv O.
Description : The project concerns the study of soil pore structure by magnetic resonance imagery and scanning techniques. A large part of pesticides migrate through a microporic structure. This structure will then be modelized; it will be integrated into existing pesticides movement models in order to predict more precisely pesticides underground movement.
Partners : NSERC, Calgary and Manitoba Universities
Status of research : bench scale
Availability of results : free
Concerned organizations : consultants

 
2. Other projects

The project concerns the development of a process that can treat hydrocarbon contaminated soils. Profitable environmental conditions are created to enhance bacterial work, especially the ones that increase bacteria transport. Contaminated areas can be isolated if necessary. The system may also include input of natural micro-organisms already adapted to contaminated soil conditions. The study has been done for diesel contaminated sand and other hydrocarbons are now studied.
