Drenos interceptores nas terras agrícolas: uma solução para conter poluição por agrotóxicos.

Abstract

Interceptor drains were suggesrted for containing subsurface contamination of agricultural chemicals. The interceptor drains treated here-in have their objective to drain the upper part of the aquifer to capture the contaminants and to delimit their extention in the aquifers. The present study is meant to investigate the effect of interceptor drains in agricultural lands in Sume, PB in function of their position, widths and depths and the relative permeabilities of the materials of the drain and the matrix. of soil. The Figure 1 presented explains the utility of such drains in containing the polluents.
