Tonolli Metals Superfund Site

The Tonolli Metals Superfund site contained soil contaminated with highly weathered #4 Fuel Oil at concentrations low enough to go directly to Phase II of the Phased Approach. Warm season grasses were planted with a nurse crop of a cool season grass for soil stabilization. Hydroseeding and cultipacking were used for plant stand establishment. Both the cool and warm season grasses developed as expected with no inhibition from petroleum hydrocarbons which have significantly decreased (P=.05) in all treatment cells except one.
The cost savings of using this approach was realized over traditional hauling and disposal costs with the additional sampling and analysis included.
