We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
The chlorinated hydrocarbon tetrachloroethene (PCE) was detected in shallow ground water (GW) and surface water (SW) of wetlands at this site in sampling by two consulting firms that took place primarily in 1996. Groundwater and surface water contamination by PCE was documented but a source area was not identified. Contaminant volume appears to be minimal in terms of mass. No continuous contamination or higher levels of contamination were identified in the adjacent upslope and upgradient surface and near-surface waters of the City of Palmer former unpermitted dumpsite, alleged to be a potential contaminant source area by Briggs property owner Ray Briggs. No hazardous substance contamination was detected in the Briggs on-site drinking water well, reported to be completed at a depth of 50 feet in bedrock. The former tenant before Briggs purchased the property in 1989 was Grizzly Trucking; operations included heavy equipment maintenance and storage. Tax Parcels are Matsu Lots C-18 and C-19. The last analytical testing was apparently done in 1996. The highest analytical result for PCE contamination in surface "marsh" water was 0.082 mg/L. The current (2016) groundwater and surface water cleanup level for PCE is 0.041 mg/L. All records in the ADEC CS file were scanned on 9/21/2017 and are in the electronic file.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 2/6/1996 | Update or Other Action | Memo by staff Krieber with subject "Palmer Airport Unpermitted Dump Site" that includes information on property owner Ray Briggs' on-site water well and adjacent City of Palmer property dump site remediation activities. Memo is relevant to Briggs site because owner Ray Briggs contended that contamination migrated to his property from the dump site. | Eileen Olson |
| 4/4/1996 | Update or Other Action | Date of Gilfilian Engineering Phase II Environmental Site Assessment report on file for Ray Briggs' property, prepared by the Small Business Association. | Eileen Olson |
| 5/13/1996 | Update or Other Action | Date of Gilfilian report "Water Test Results Ray Briggs' Property, Palmer, Alaska" summarizing lab results from a 4/23/1996 ground water monitoring event. Elevated results for PCE found in water and sediment samples. | Eileen Olson |
| 7/13/1996 | Update or Other Action | Date of letter from Mike Krieber to US Small Business Administration reviewing ground and surface monitoring reports. Letter notes that the source of the low level contamination on the Briggs property has not been identified. | Eileen Olson |
| 7/23/1996 | Document, Report, or Work plan Review - other | Staff reviewed a soil sampling report and a GW/SW sampling report. At reported contaminate levels, cleanup is not warranted nor required by the department. ADEC requests a GW gradient investigation be performed. | Mike Krieber |
| 8/8/1996 | Update or Other Action | Contaminant of concern is tetrachloroethene (PCE). TCE was not detected. PCE found in surace 'marsh' water and in shallow (2' deep) groundwater. Contaminant distribution appears to be intermittent and discontinuous. | Eileen Olson |
| 8/8/1996 | Site Added to Database | TCE and GW contamination. | Mike Krieber |
| 8/30/1996 | Update or Other Action | Status report by Gilfilian Engineering to US Small Business Administration addressing Department questions including comments regarding the probable transport mechanism for contamination. | Eileen Olson |
| 10/14/1996 | Update or Other Action | ADEC letter from Krieber to US SBA summarizing responses from Gilfilian Engineering to ADEC, including comment that additional information is needed to determine whether a source of contamination remains. | Eileen Olson |
| 10/31/1996 | Update or Other Action | Gilfilian report received with subject line "Analytical Sample Results, City of Palmer Airport Property, Conducted as part of the Environmental Assessment of Ray Briggs' Property" prepared for US SBA and dated October 31, 1996. The report notes that the airport ground and surface water flow paths indicate a source of contamination that is not originating on the Briggs property. | Eileen Olson |
| 12/20/1996 | Update or Other Action | ADEC letter dated 12/20/1996 from Krieber to US SBA in which Krieber suggests that source of PCE is on Briggs property. ADEC reviewed soil, surface water and ground water sampling reports. PCE is slightly over MCLs in a drainage ditch's surface water (37 ppb) and is observed in low levels in the ditch soil. One other shallow soil sample showed low TCE. Because of low levels and no identifiable source, ADEC stated in the letter that further investigation and cleanup was not needed. | Mike Krieber |
| 12/23/1996 | Site Ranked Using the AHRM | Site ranked by staff. | Mike Krieber |
| 5/22/1997 | Update or Other Action | Briefing on file written by staff Olson and Krieber for ADEC management re site status, priority and recommendations. Briefing notes that TERRASAT sampling effort, reported in the 4/4/96 Gilfilian report, reported PCE to be present at a level of 0.082 mg/L in "marsh" water on the Briggs property. | Eileen Olson |
| 11/1/1999 | Update or Other Action | Report on file dated Nov. 1999 was rec'd by ADEC in February 2001 from consultant Terrasat. The report is titled "Site History Documentation and Geophysical Investigation of the Former Palmer Airport Dump Site, Palmer, Alaska" and was prepared for Ray Briggs. Report includes timeline beginning in 1978. | Eileen Olson |
| 5/10/2000 | Site Ranked Using the AHRM | Changed the GW Usage Value from 0.4 to 1. | Eileen Olson |
| 11/27/2000 | Meeting or Teleconference Held | Staff Olson testified in federal court Briggs v. City of Palmer (A95-007-CIV) regarding the Department's oversight and review function with respect to contamination at the Briggs site and adjacent Palmer airport property. | Eileen Olson |
| 12/3/2002 | Update or Other Action | Updated latitude and longitude based on coordinates supplied by Mike Crotteau of the Wellhead Protection Program as digitized using plat and/or orthophoto maps. | Former Staff |
| 7/20/2004 | Update or Other Action | File number issued 2245.38.020. | Aggie Blandford |
