Use of nanoscale iron for the remediation of groundwater damages : fact sheet nano products / Umweltbundesamt

Abstract

The applicability of a number of nanomaterials Groundwater damages can be caused for instance by the inappropriate handling of environmentally hazardous materials, disasters or improper handling and disposal of waste. The so-called pump and treat method was the method of choice for the remediation of groundwater damages in the past. It involves the transport of the contaminated groundwater through remediation wells and the purification in an on-site system. for the remediation of environmental damages is being examined and tested. Preliminary experiences suggest that they allow the better, faster and more cost-efficient remediation of environmental damages. The use of nanoscale iron for the remediation of groundwater damages represents an innovative remediation method. At present, it is still in development in Germany and has only been used in individual cases in the past. For this reason, the experience with this approach is still relatively low.
