Abstract

A system for soil, groundwater, or surface water remediation, comprises a water supply including a first fluid stream in fluid communication with a first injection point, and a second fluid stream in fluid communication with a second injection point. A first surfactant pump can be adapted to inject a surfactant into the first fluid stream, and a second surfactant pump can be adapted to inject a surfactant into the second fluid stream. A first oxidant pump can be adapted to inject an oxidant into the first fluid stream, and a second oxidant pump can be adapted to inject an oxidant into the second fluid stream.
