Evaluation of test (pilot) injections

The pilot tests applied in June 2016 in two contaminated aquifers (Barreiro, Portugal, and La Felguera, Spain) were evaluated in terms of the effect of nanoparticle injection on hydrogeology of aquifers and on removal of heavy metals from groundwater. In Barreiro it was observed that the nanoparticles showed reduced mobility. Therefore a modification of nanoparticles […]

Installment of permeable reactive barriers

During April and May 2017, REGROUND applied first full-scale installment of permeable reactive barrier using Iron-oxide nanoparticles. The injections took place in same contaminated aquifers as pilot injections (June 2016); one in Barreiro, Portugal, and one in La Felguera, Spain. Prior to application, a remediation and monitoring plan was prepared. At each site, 9 injection […]

TITLE: “Colloidal behavior of goethite nanoparticles modified with humic acid and implications for aquifer reclamation” AUTHORS: Alberto Tiraferri, Laura Andrea Saldarriaga Hernandez, Carlo Bianco, Tiziana Tosco, Rajandrea Sethi (POLITO). RELEASE DATE: 11 March 2017 LINK: https://link.springer.com/article/10.1007/s11051-017-3814-x ABSTRACT: Nanosized colloids of iron oxide adsorb heavy metals, enhance the biodegradation of contaminants, and represent a promising technology to clean up contaminated aquifers. Goethite particles for aquifer reclamation were recently synthesized with […]

Development hightlights in 2016

Two main developments are: Performing test injections New set of nanoparticles REGROUND has successfully completed two pilot (test) injections in field sites in Spain and Portugal. The aim of these injections were to test the mobility of REGROUND nanoparticles in real aquifer, and therefore their ability to build a permeable reactive barrier. At this stage, […]

Science in big-scale

First batch of large-scale nanoparticles for remediation of heavy metals in groundwater are being produced in UDE. These particles are planned to be injected in next two weeks in two fields (Spain and Portugal). In total, ca. 60 cubic meters of nanoparticle suspension will be used in this step, to evaluate the efficiency (performance) of […]
