Remediation pilot testing is performed in order to verify the effectiveness and appropriateness of the laboratory-selected technologies under the site-specific conditions.
The prerequisite for the pilot testing is the laboratory experiments, where the chemical reaction course, physical changes, and the biological pollutant degradation effectiveness is tested in a smaller scale. The transfer of laboratory research into the semi-industrial scale conducted directly at the site is the pilot test.
Prior to the pilot test initiation, the hydraulic pumping, pressure, or tracer tests are conducted, with the objective to precisely describe the subsurface groundwater flow conditions (flow direction, flow velocity, or hydraulic conductivity) directly affecting the remediation course.
During the pilot test, an intensive monitoring of all environmental conditions is performed. The attention is focused at the physicochemical parameters, groundwater chemistry, and - of course - changes of target contaminant quality and concentration levels in the subsurface matrix.
