Problems/Comments
On May 7th, 1998, a non-regulated heating oil tank (tank #7) was decommissioned at the residence. Contaminated soil was found near the east end of the tank at a depth of two feet below ground surface (BGS) extending down to a layer of clay or silt near the bottom of the pit. The excavation measured six feet by twelve feet (72squarefeet) and a depth of six feet BGS. Two analytical samples were collected from a location corresponding with the pipe trench based on field screen readings. An estimated volume of two cubic yards of contamination appeared in an area associated with the fuel supply and return lines and was placed between liners on-site. Groundwater was not encountered in the excavation. There is a public utility water line nearby and reportedly a drinking water well located near the site. NPS and DEC staff determined that additional excavation was impracticable. The fuel supply lines were capped and the excavation was backfilled with clean soil. The tank appeared to be in good condition. The volume of remaining contamination was not estimated.

| 10/29/2002 | Update or Other Action | 2/28/01 CAFR from Platt Environmental states 5 discrete confirmation samples collected from re-excavated UST location. DRO at two locations < 1,000 ppm. Benzene at 0.05 at one location. Fourteen cubic yards transported to USR in Juneau. Platt recommended closure at this site but it appears GW monitoring may be merited. Soil contamination documented w/in 2" of the GW table. | Bill Janes |
| 6/21/2005 | Update or Other Action | Name changed to NPS Indian Point (GBJ-A Resid) to reflect NPS designator. | Mike Jaynes |
| 9/30/2008 | Update or Other Action | Site drawings from and discussion with Bill Huebner (NPS) confirms that a drinking water well maintained by the Park Service is used at the site. Shallow well appears to be upgradient ~250 ft from GBJ-A residence and ~360 ft from GBJ-B site. At a minimum, GW monitoring is recommended at this well prior to site closure consideration. | Daniel Fremgen |
