PROJECT STORY
The challenge
Chromium-6 soil contamination in an urban location is a threat, and Arcadis found a solution that prevented a more serious problem for the environment and public health.
Remediation of chromium-6 contamination
Decontamination of urban soils
The solution
Through the GRiP® Remediation Program, the potential alternatives were analyzed, and the choice was made to use a bioremediation process that neutralized the threat, employing a technology developed by Arcadis itself.
The impact
After a year, the remediation proved successful, with the concentration levels of chromium-6 falling to a point where they ceased to pose an environmental threat.
The poison hidden beneath the earth
We don't normally spend time thinking about the ground we're walking on. But most of what we do is 'recorded' under our streets, buildings and industrial plants. The ground absorbs and hides the traces of our activity without us realizing. And sometimes what it's hiding isn't good.

Remediating the chromium-6 contamination
The factory enlisted our GRiP® Remediation Program, which guarantees remediation upfront at a set price, and we got to work.
The first thing that the Arcadis technicians did was think about how to neutralize the threat posed by the chromium-6 and avoid a larger environmental problem. Removing tons of contaminated soil from beneath the factory was not a feasible solution, so a quantitative risk assessment was conducted so that reasonable remediation targets could be established.

Neutralization of the environmental threat
The expected results of the remediation process were achieved after a year, with the concentration of chromium-6 gradually decreasing to the point that it no longer posed a threat to public health.
We were able to avoid a serious environmental accident that would have compromised the quality of the river water and its use in irrigation and water supply. That alone made the whole year's work worthwhile.
