HEISTT is a European research project for SME clusters and stands for “High Efficiency In Situ Treatment Technology for Contaminated Groundwater”. The project is led by a Turkish Institute called TUBITAK MARMARA RESEARCH CENTER active in water, waste, air and soil, while EUCETSA’s involvement is especially in the dissemination of the results.
The proposed HEISTT solution is the rapid installation of groundwater treatment chemicals as an in situ subsurface remediation technique, brought about by the use of ultrasonic assisted injection technology to create a closely spaced grid of single treatment small diameter wells to a depth of 20 meter. As part of the bore holing process, remediation chemicals will be introduced in to the ground contained within a geotextile sock. Diffusion of the chemicals (oxygen release compounds, hydrogen release compounds, zero-valent iron or chemical oxidants) occurs through the permeable geotextile material.
Injection target cycle time will be 5 minutes from hole to hole at 1 m spacing. The spacing of these boreholes will be decided by the concentration of contaminant and the required rate of clean-up. This whole system will be passive, i.e. requiring no energy to function after installation or operator maintenance. A range of equipment options are envisaged, from simple attachments for existing excavation plant – which will be the primary focus of HEISTT, enabling rapid take up of the process by SMEs due to the affordability of retrofit - through to dedicated bespoke machinery.
