Cost-Effective Pollution-Control Tool Developed By Indian Origin Scientist
The scientist in question is Indrajeet Chaubey, an associate professor of agricultural and biological engineering, Purdue University.
He combined a best management practices tool with a complex genetic algorithm that can search out the best solutions for non-point source pollution control in a watershed.
By analyzing data from an area in just a few hours, the tool can compute the most cost-effective pollution-control strategies for water resources affected by agriculture, a process that currently takes weeks or months.
"When you have got limited resources to control non-point pollution in an area, you have to decide where to best use your resources," Chaubey said. "At the same time, you want to be sure you don't disrupt the agricultural production in an area," he added.
Chaubey has spent the last several years developing a best management practices tool that takes into consideration all feasible solutions for decreasing non-point source pollution, or pollution that gets into water through runoff.
The tool determines the best solution, such as changes in tillage practices, grass coverage and structural changes on the land, based on the amount of pollution that can be eliminated, the economic impact to agricultural land and other factors.
The calculations used include soil, water, topography and other data usually collected by governmental agencies.
