(Former) chemical laundries

Last century, chemical laundries made extensive use of chlorinated solvents such as perchloroethylene and trichlorethene. These operations were often located near water or in urban areas. The resulting contamination is mobile and highly biodegradable. We encounter many situations with a highly contaminated source zone and a considerable plume of degradation products, such as dichlorethenes and vinyl chloride. The solvents used are heavier than water and can easily sink to lower depths and form a sinking layer on a poorly permeable bottom formation.

Our customers are frequently problem owners, developers, foundations and engineering firms, or public authorities. We develop our remediation plans based on the customer’s needs. The basis of our approach is, in most cases, biodegradation. This process is sustainable and can strongly inhibit any adverse effects on surrounding areas because the degradation occurs in the soil on site. If any DNAPL is present on site, it is effectively eliminated by the in-situ system, while excavation sometimes constitutes part of our approach. Introduction of our electron donor allows anaerobic degradation of the contaminant to occur in the soil. Various techniques are applied, such as direct injection and circulation, possibly supplemented by inoculation and incubation of the soil. Introducing the electron donor in soil optimises degradation conditions. We monitor the process ourselves so that we can promptly make any necessary correction to our in-situ remediation.

In situ remediation measures enable us to effectively eliminate contaminants from former laundry sites that are sited under gardens and homes, for example. We can flexibly provide services that are in line with customer expectations.
