Microbial Technologies - Case Studies
A breakthrough in our laboratory investigations lead to the development of a simple, economical treatment process, loosely based on the concept of vertical flow wetlands. Metals and other toxic constituents are entirely removed, and the treated effluent is rendered non-toxic in conventional (D. magna, rainbow trout) toxicity tests. This is ...

The Source Recharge Area: mass loading of contamination to the ground water
Macropores don't typically follow a straight path whether or not it is expressed vertically. Therefore, macropore flow of water or product to the water table will follow a herky-jerky (tortuous) path as it drains to the water table. This tortuous-vertical flow tends to laterally distribute any contaminant discharged to water table over a greater area, than if vertical ...
