In 2018, Sugarloaf Island in London became the focal point of bioremediation trials spearheaded by John F Hunts for the developer Vastint. Following the triumph of the Meridian Water project, Skyhawk’s esteemed Hydroeater EVP was chosen for the trials at this site. However, a departure from the tried and tested methods emerged when the contractor’s trials manager elected to employ biopiles, diverging from Skyhawk’s established method statement. While this approach still achieved the set remedial target, it somewhat curtailed the full potential of the bioremediation process. This experience underscored the criticality of adhering to specific product method statements to truly harness optimal results.
