In response to the need for an all encompassing treatment device to deal with trash, debris (organic and non organic) solids, sediment, total suspended solids (“TSS”), metals (dissolved/particulate), nutrients (dissolved/particulate), oils, hydrocarbons, polycyclic aromatic hydrocarbons (“PAH”), and pathogenic bacterium contaminants, the City of Oceanside authorized the installation of the Modular Wetlands Device in April of 2008.
