The Aluminum Finishing Company site is a former metal-finishing facility that was in operation from March 1981 to January 1993. The operator was electroplating metal nuts and bolts of various sizes by first cleaning them in a solution of caustic sodium cyanide, and then electroplating them with cadmium and coating with chromium. The metal-cleaning solution was neutralized with sulfuric acid. Wastewater from the electroplating process was collected in tanks and left to evaporate. The City of Houston had previously cited the operator for discharging plating wastewater into the city’s sanitary sewer system. At the time of the investigation, six rectangular tanks contained varying amounts of cadmium/chromium sludge. The site consisted of a large metal warehouse and a former office building at the time of the hazard ranking. Currently, the large metal building is occupied by Riverside Kitchen and Bath and used for storage of lumber and partially finished cabinets, and other woodworking operations. The former office building had been converted to the current owner’s residence.
