Stemple & Ward
Pittsburgh, PA – 1996 – $120,000
Scope of Work:
Stemple & Ward purchased a public transportation garage and converted it to an electric motor winding facility. Years afterwards, gasoline odors began seeping through the sewage vents. Investigation identified four historic 5,000 gallon underground storage tanks previously used for leaded gasoline. The tanks had leaked into the surrounding subsoils and migrated into the storm sewers.
Neumeyer Environmental used ground-penetrating radar to locate the tanks. We excavated the tanks and removed the mix of water and product. Neumeyer Environmental shipped 20,000 gallons off-site to a recycler for processing. Neumeyer Environmental purged the tanks of flammable gas, removed and disposed them at a licensed tank disposal facility. 2,500 tons of adjacent subsoils required removal and disposal at a regulated facility.
