Conduct Additional Site investigation at Hotel Powerhouse site

The scope of this project is to determine the current status of soil contamination at the Hotel Powerhouse site by means of drilling 5 borings to determine maximum concentrations of diesel in the soil.The site is the result of a surface spill of approximately 10,000 gallons of diesel from a railroad tanker car in 1972, releases from a diesel Underground Storage Tank (UST) serving the Powerhouse removed in 1993 and 50 feet of fuel discovered in a 300 foot deep 8-inch unused drinking water well in the 1990s. Several Site Assessments were conducted at the site, with numerous soil borings delineating the lateral and vertical extent of soil contamination. Approximately 1,500 cubic yards of contaminated soil were removed from the site in the early 2000s. Studies determined that the contamination in the well was not related to the releases to the soil but most likely, it was mistaken for a tank fill port. This well was decommissioned in 2012.

The main focus is whether soil contamination remains above the direct contact cleanup level at the site. The goal will be to close the site with institutional controls if levels are sufficiently low at the time of this current round of testing.
