Problems/Comments

Buried drums of asphalt uncovered soil contamination, sampling was done in summer 1993 by contractor. 1996- Results and site investigation work from 1993 submitted by CBJ. PA submitted by Tryck, Nyman, Hayes in 1987 stated that benzene and toluene were detected in the drinking water well of a nearby restaurant during 1985. No conclusive evidence was found to link the contamination to the Red Samm site. The restaurant hooked up to city water in 1986. 1996-Contamination encountered during foundation construction for elementary school. Work halted, and consultant hired to do assessment. Site name has been changed from Red Samm Construction to current. Rescored. Tract B-1 and B-2, USS 1284. Janes assigned at site closure. 6/26/18: Tar/asphalt has been observed coming to the surface on the baseball field and a consultant is conducting an investigation. As a result, the site has been reopened.

Danielle Duncan
7/27/2018	Site Visit	Visited the site while Nortech excavation was underway. Buried, solid asphalt fill was observed in addition to tacky, tar/chip seal material. Approved the use of solid, asphalt as fill, but required that the tacky material be excavated to a depth of 3 feet to prevent direct contact by the public. Below the asphalt materials, contaminated soil of unknown composition was observed and sampled. The excavation was lined and backfilled. Pending analytical results, the material will likely be excavated and disposed of appropriately.	Danielle Duncan
8/8/2018	Update or Other Action	The minor excavation on the playground was completed. Approximately 3/4 yards of soil was excavated that had some asphalt but was less extensive than what was observed on the ball field.	Danielle Duncan

Areas of the site where asphalt tack was observed surfacing and subsequently excavated were the ballfield and the Riverbend Elementary School playground. Asphalt tack, batched asphalt, asphaltic concrete fill, and stained soil were excavated from the areas. Continued monitoring for the presence of asphalt tack is warranted and any observed releases must be reported to the ADEC Contaminated Sites Program.	Danielle Duncan
