Keystone Environmental designed and installed a biological treatment plant to treat pumped groundwater containing PAH and PCP, to surface water discharge requirements – almost non-detect.

Began a long-term relationship with West Fraser Mills. At their Eurocan Pulp and Paper mill, leachate from their chemical waste landfill was leaching into a ditch that connected to a freshwater course of interest to Fisheries Canada.Keystone Environmental designed and constructed a slurry wall to intercept the leachate and direct it into a catchment pond where the water was then pumped to the mill wastewater treatment system.

At the Titan Steel nail plant in Richmond, we managed the excavation of many years of metal laden sludge accumulation in their wastewater treatment lagoons.
