The 6-acre Aladdin Plating Site is located near Scranton, Pennsylvania. Land use surrounding the area is predominantly residential. A residential community of fifty homes is located one-half mile to the southeast. An estimated 11,000 people rely on private or public water supplies for drinking water. Surface water bodies include Leggett's Creek and Bell Mountain Creek.

From 1947 to 1982, the Aladdin Electroplating Company was involved in chromium electroplating and decorative electroplating. Liquid wastes generated from these processes were deposited into two on-site unlined surface impoundments via an open drainage ditch.

Various state and federal environmental agencies performed numerous investigations of Aladdin Plating Company. The Pennsylvania Department of Environmental Resources (PADER) conducted soil sampling activities at the site in 1983, and discovered elevated levels of chromium in the site's soil. A Preliminary Site Assessment (PSA) was performed by PADER, EPA and the Technical Assistance Team (TAT) in February 1987. As a result of the findings of the PSA, EPA began sampling residential wells surrounding the site in March 1987. EPA initiated a Preliminary Site Evaluation (PSE) in April 1987 and issued a ROD for Operable Unit 1 to address soil contamination in September 1988.

This ROD addresses OU2; namely the contaminated groundwater at the site. The objective of the remedy is to reduce risks associated with exposure to contaminated groundwater. Institutional controls will be the primary remedy at the site for the low-level threats in the groundwater.

The remedy status for the media addressed in this ROD are as follows: Groundwater 1 is Final Action. The media volume associated with this site is not documented. The state does not concur with the selected remedy.
Remedy:  The selected remedial action for the site includes implementing institutional controls prohibiting well-drilling in the shallow water-bearing zone beneath the site and excavating within the entire 6-acre parcel; collecting and analyzing groundwater samples from monitoring and residential wells for thirty years to ensure that contamination is not migrating to locations where it might present a threat to human health or the environment; the wells will be sampled for chromium on a quarterly basis for the first five years and then annually thereafter for thirty years. The overall Present Worth costs are $178,256. The annual O&M costs are $21,249 (Year 1 to 1.) The annual O&M costs are $16,249 (Year 2 to 5) The annual O&M costs are $2,012 (Year 6 to 30).
