Action Information

Action Date Action Description DEC Staff
4/2/1999 Site Ranked Using the AHRM By staff. Deborah Williams
5/6/1999 Update or Other Action Sample results from drinking water wells were sent to RP and adjacent property owner. Both water samples were below the MCLs. Deborah Williams
5/28/1999 Site Characterization Workplan Approved Workplan approved to install three monitoring wells (one upgradient and two downgradient), twice a year. Deborah Williams
5/29/1999 Cleanup Level(s) Approved Groundwater monitoring wells will be sampled twice a year. Deborah Williams
9/17/1999 Site Added to Database Soil and groundwater contamination. Deborah Williams
3/9/2000 Site Characterization Report Approved Site Characterization report submitted to ADEC by Shannon & Wilson. Benzene level was found at 2.37 ppb in MW-2. DRO level was below detection limits. The on-site drinking water well sample results were below detection limits. Deborah Williams
11/13/2000 Update or Other Action Groundwater monitoring report submitted by Shannon & Wilson. Benzene level at MW-2 was 0.734 ppb. DRO was below detection limits. The drinking water well sample results indicated levels below detection limits for BTEX. Deborah Williams
12/18/2001 Update or Other Action Groundwater monitoring report submitted by Shannon & Wilson. Water samples were collected on 7/6/01 and BTEX and DRO were below detection limits. Drinking water well sample results also indicated DRO and BTEX below detection limits. Deborah Williams
7/10/2002 GIS Position Updated Changed the Latitude, Longitude, Method Accuracy, Accuracy and Unit fields. Heather Goldman
8/11/2004 Update or Other Action Groundwater samples collected from the monitoring wells and the on-site drinking water well on June 7, 2004, did not contain BTEX compounds that exceed the cleanup levels for the DRO or BTEX. Shannon & Wilson recommends that a NFA be issued for the site. ADEC requested at least one or two indoor air samples be collected from the basement to ensure that vapor intrusion is not a complete pathway. Deborah Williams
8/27/2004 Update or Other Action ADEC talked to Shannon and Wilson and they stated that the Insurance Company refused to pay for indoor air sampling. The insurance company is only concerned about protecting the waters of the State. Shannon and Wilson also stated that there is currently new owners at the site who may not be aware of the site conditions. Their names are Stephen and Michelle Hekeler. Deborah Williams
9/3/2004 Update or Other Action ADEC sent a letter to the new owners regarding the contamination at the property. Along with the letter, ADEC sent a copy of the Notice of Environmental Contamination to recorded on the deed so that a conditional closure could be issued for the site. Deborah Williams

Contaminant Information

Name Level Description Media Comments
DRO Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil DRO found in soil beneath garage foundation at 8,920 mg/kg in 1999.
Toluene Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil Toluene found in soil beneath garage foundation at 26.7 mg/kg in 1999.
Benzene Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil Benzene found in soil beneath garage foundation at 2.56 mg/kg in 1999.
Ethylbenzene Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation Soil Ethylbenzene found in soil beneath garage foundation at 34.4 mg/kg in 1999.
Xylenes (total) > Human Health/Ingestion/Inhalation Soil Xylenes found in soil beneath garage foundation at 161.8 mg/kg in 1999. This concentration exceeds outdoor inhalation cleanup level of 63 mg/kg, but DEC believes a de minimus amount is present and will not affect outdoor air.

Requirements

Description Details
Advance approval required to transport soil or groundwater off-site. Standard condition.
Movement or use of contaminated material (including on site) in a manner that results in a violation of the water quality standards is prohibited (18 AAC 70) Standard condition.
Periodic Review Any future change in land use may impact the exposure assumptions cited in this document. If land use or ownership changes, these management conditions may not be protective and ADEC may require additional remediation and revised conditions. Therefore the RP/landowner shall report to ADEC every 5 years to document land use, or report as soon as RP/landowner becomes aware of any change in land ownership and/or use, if earlier. The report can be sent to the local ADEC office or electronically to DEC.ICUnit@alaska.gov.
Groundwater Use Restrictions Installation of groundwater wells requires ADEC approval.
Excavation / Soil Movement Restrictions Sub-surface soil contamination is located near the north and east side of the garage. When contaminated soil becomes accessible or when construction is planned over the contaminated area, contact ADEC to determine if a workplan is needed.
