Pollutant Filter Sock

Pollutant Removal – EnviroSoxx stops pollutants from leaving your site.

EnviroSoxx® is the most versatile and cost-effective filter for stormwater pollutant removal. A passive filtration system ready to install on any site, EnviroSoxx targets the most common pollutants in stormwater runoff, particularly in urban watersheds, sensitive receiving waters, and Total Maximum Daily Load – TMDL (§303d) listed water bodies. EnviroSoxx help industrial stormwater permit holders/MS4s comply with their permits, easily and quickly. EnviroSoxx can be applied on bare soil, vegetation, or impervious surfaces in the path of sheet flow or concentrated flow to target stormwater pollutants.

EnviroSoxx is available in two filter blends to target common pollutants.
Industrial Blend: Targets a range of heavy metals, hydrocarbons, nutrients, and sediment. Also targets pH.
Advanced Blend: Targets bacteria, nutrients, hydrocarbons, select heavy metals, and sediment.
