Description

Construction sites appear in every type of urban and rural landscape including municipal harbors and along rivers, lakes and other waterways.

Dredging projects are a benefit to shipping and other waterfront construction projects. The dredge spoils must be dewatered prior to disposal or reuse and the water may need to be treated prior to discharge back into the water source.

As is often the case, once dredge spoils are excavated and the water is being drained, metals or contaminants which were otherwise stable can leach from the sediment. Contaminants may include suspended solids, organic hydrocarbons, polychlorinated biphenyls (PCBs), heavy metals, lead, iron, emulsions, algae, dyes, ultra-trace mercury, selenium and more. That water must be treated to required acceptable levels prior to being reintroduced to the water source.

Our diverse, mobile treatment systems are enclosed making them ideal for sites with noise restrictions and can also address odor and air emission issues to ensure compliance.
