Problems/Comments

A 300-gallon home heating oil tank was removed on 1/17/1995 resulting in a release of an unknown amount. Approximately 18 cubic yards of soil was removed and returned to the excavation after field screening and one lab sample resulting in 330 milligrams per kilogram (mg/kg). Free product discovered in monitoring well in 1999. Three inches of free product was noted in monitoring well B2MW on 4/26/2002. Latest groundwater monitoring data (2005) indicated that a monitoring well just south of the property boundary contains 96.6 milligrams per liter (mg/l) diesel range organics (DRO) in groundwater as 0.25 inch free product.

Action Information

Action Date Action Description DEC Staff
1/17/1995 Update or Other Action Reviewed the Shannon & Wilson, Inc. "Underground Storage Tank (UST) Site Assessment at 1001 C Street, Anchorage, Alaska" dated 2/2/95 and received by the department 9/23/99. A 300-gallon home heating oil tank was removed on 1/17/95 resulting in a release of an unknown amount. Approximately 200 gallons of water was pumped from the tank prior to removal. Approximately 18 c.y. of soil was removed and returned to the excavation after field screening and one lab sample resultng in 330 mg/kg DRO. The excavation went to 6 feet deep. No GW was encountered. DRO and BTEX sampled for resulting in the maximum lab result of 9,000 mg/kg DRO at 5.5 feet bgs, ~6" below the tank bottom. No BTEX was detected. Bill Petrik
2/13/1995 Site Characterization Report Approved Reviewed the Shannon & Wilson, Inc. "Underground Storage Tank (UST) Release Investigation;1001 C Street; Anchorage, Alaska" dated March 1995 and received by the department 9/23/99. A 6'x9'x13.5' deep pit was excavated at the approximate location of a sample taken 1/17/95 that resulted in 9,000 mg/kg DRO in an attempt to evaluate the extent to which petroleum hydrocarbons contaminated soil and GW. GW was not encountered. No samples in the bottom or sidewalls of the excavation was performed due to slumping to 7' bgs. Approximately 15 c.y. of soil was excavated and based on field screening segregated into stockpiles of 11.5 c.y. of contaminated soil and 3.5 c.y. of clean soil. The contaminated stockpile was placed on a liner and covered. On 2/20/95 Boring B1 was drilled to 27' bgs. 7 soil samples were taken every 2.5' starting at 10' bgs and ending at 22.5' bgs. Sample B1S4 taken from 17.5 to 19.5' bgs had the highest screening level and was sampled. The result was 1,700 mg/kg DRO. Sample B1S6 taken from 22.5 to 24.5' bgs resulted in 20 mg/kg DRO. Four clean stockpile screening PID sample readings ranged between 2 to 3 ppmv and no samples were submitted. Sample S7 from the contaminated soil stockpile had the highest PID reading and was submitted for analysis resulting in 4,880 mg/kg DRO. GW was encountered at 23.6' bgs and a sheen on it noted. Bssed on the absence of finer grained soils, released fuel most likely migrated mostly vertically to the water table. Bill Petrik
3/15/1995 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). Reviewed closure site assessment and corrective action workplan (to install a passive bioventing system). Did not approve the workplan as the passive system estimated 5 years or more for remediation. Lynne Bush
4/3/1995 Meeting or Teleconference Held Conference call between Eileen Olson and Lynne Bush of ADEC with Lee Ann Osgood of Shannon & Wilson. Further excavation of contamination at the site is not an option due to depth of the contamination and potential hazards to existing structures. Maggie Cross, the homeowner may want to get the work completed rather than dragging it out. ADEC wants Ms. Cross appised of the current status by S&W. ADEC requests active remediation. And time estimate for passive remediation cannot be made because of so many variables. Eileen Olson
4/6/1995 Cleanup Plan Approved A request to transport 17 cubic yards of petroleum contaminated soil from the site was approved this date. Lynne Bush
4/6/1995 Site Added to Database Site added to database. Lynne Bush

7/14/1997 Update or Other Action The department received a call from Dee Hanson, homeowner, who is wondering is she will receive any documentation that the site is "clean and closed" as she wants to incorporate language in an agreement holding the Salvation Army responsible in the event that she wants to sell the property. Eileen Olson
1/27/1998 Potentially Responsible Party/State Interest Letter A letter was sent this date to Major Gilman of the Salvation Army indicating that our records show that the Salvation Army is the responsible party for the site and the department requests written response within 15 days of receipt of the letter as to their intent for responsibility and intentions regarding remedial activities is responsiblity is not disputed. The letter also mentioned the department's Cost Recovery Policy. Ray Dronenburg
2/23/1998 Update or Other Action ADEC requested additional site work by letter including GW sampling, fate of IDW water from installation of MW, and a work plan for future soil and GW remediation.. Ray Dronenburg
2/23/1998 Update or Other Action (Old R:Base Action Code = RI - Remedial Investigation). Reviewed a copy of the Shannon & Wilson (S&W) report "Monitoring Well Installation and Soil Disposal; 1001 C Street; Anchorage, Alaska dated July 1995 and received 2/17/98. Approximately 3.5 c.y. of clean soil stockpiled on site was backfilled into the former pit excavation on 6/13/95 with more clean fill imported to bring the excavation to grade. An approximate 15 c.y. contaminated soil stockpile on site was transported to Alaska Soils Recycling (ASR) for thermal treatment that was completed on 6/20/95 based on a 7/1/95 ASR letter to the department. Monitoring well B2MW was drilled, installed, and purged on 6/16/95. A sheen was noted on the drummed purge water. The sampled GW was analyzed for GRO, DRO and BTEX. Sampling results indicated GW contamination - 0.96 mg/l DRO, 0.4 mg/l GRO, ND for benzene, 0.002 mg/l toluene, 0.0018 mg/l ethylbenzene, and 0.03 mg/l total xylenes. Total BTEX .0338 ppm. Soils at 17 to 19.5' below ground surface left in situ exceeded 1700 ppm. S&W contends that the GRO and BTEX components are potential contamination migrating from a site at 901 (840) C Street. Eileen Olson
3/18/1998 Update or Other Action Received a response to the 2/23/98 department letter. The letter did not dispute the Salvation Army being responsible and indicated that Shannon & Wilson was contacted to perform additional monitoring work as well as develop a work plan for further remedial site actions. The letter included an attached copy of the IDW water receipt from Alaska Pollution Control. Ray Dronenburg
12/1/1998 Update or Other Action The department received a copy of an "Escrow Holdback Agreement" dated 1/31/95 from Dee Hanson for the Salvation Army to deposit $4,500 w/o interest with the escrow agent for insuring cleanup work at the subject site to be completed by 5/1/95. Ray Dronenburg

3/4/2002 Update or Other Action Contacted Major Murray regarding site status. He said he was unaware of any reason why Shannon & Wilson had not proceeded with the work since the contract was given to them. He promised to look into the matter. Beatrice Egbejimba
3/7/2002 Meeting or Teleconference Held Visited the site at Samia and Matt's request. They also invited Mavis who declined. The purpose of the meeting was to pick out appropriate locations for the three monitoring wells. The gas, sewer and water lines were already located and mapped out before we arrived. The driller was also present to confirm if he could drill in any location we picked out. At the site we discovered that the site plan was not to scale. Changes were made to two well locations and an alternative location was picked out for the south well. Shannon & Wilson has not been able to communicate with the property owner on which the south well should be located. Beatrice Egbejimba
3/19/2002 Update or Other Action Sent letter to Major Murray of the Salavation Army with ADEC approval of the Shannon & Wilson "Revised Work Plan for Additional Release Investigation Services, 1001 C Street, Anchorage, Alaska" dated 1/22/01 and 3/13/02 revised map. Beatrice Egbejimba
4/10/2002 Meeting or Teleconference Held ADEC met with Mavis Perron and Samia of Shannon & Wilson at the site. Shannon & Wilson would like to put in wells on Friday and Saturday but Mavis suggested they wait till the following weekend. She needs more time to consult with her Attorney and get in touch with the owner of the vehicle parked close to the proposed location. Shannon & Wilson can not wait because they have already applied for a right of way permit and received an approval for those days. Finally it was agreed that Marvis would be in touch in a day or two after consulting with her attorney. Beatrice Egbejimba
5/31/2002 Update or Other Action The CSP granted permission to dispose of impacted soil at Alaska Soil Recycling and impacted water at Alaska Pollution Control. 80 gallons of groundwater were collected from the site for processing on 5/21/02. Beatrice Egbejimba
6/7/2002 Update or Other Action 2 drums of contaminated soil cuttings from Borings B6 and B7 were transported to Alaska Soil Recycling for processing that resulted from site activities on 5/21/02 after receining ADEC approval. One aditional 55-gallon drum and 10 gallons of water and product from the March 2000 product recovery test remains at the site. Beatrice Egbejimba
6/12/2002 Update or Other Action Received a cc of a letter sent 5/30/02 from Kay Rawlings of the Department of Law to the Salvation Army with an attached Bill for Collection for the period 11/16/01 through 3/31/02. Beatrice Egbejimba
6/24/2002 Site Characterization Report Approved Upon review of the Shannon & Wilson "Additional Release Investigation Services, 1001 C Street, Anchorage, Alaska" report dated June 2002 received by the department on 6/12/02, the ADEC sent a letter to the RP approving it. In order to further characterize the site, Borings B5 and B6 were advanced on April 12, 2002, and B7 on April 20, 2002 to 28 feet bgs, conducting soil screening and sampling for DRO and BTEX during the process. The boring logs indicated that a petroleum odor was detected during drilling of Boring B6 below 20 feet bgs and in Boring B7 below 19 feet bgs. Monitoring wells were subsequently installed in all three borings. Groundwater was encountered at approximately 22 feet bgs in all three borings during drilling and did not fluctuate more than one foot when subsequently measured within three weeks after drilling. Groundwater elevation measurements undertaken subsequently indicated the GW flow was to the southwest with a gradient of about 0.001 foot/foot. Three inches of floating product was measured in monitoring well B2MW prior to purging. Monitoring wells B4, B6, and B7 exhibited a sheen or slight sheen. Soil samples from Borings 6 and 7 were ND for BTEX but DRO was above cleanup levels in each of these borings at 983 mg/kg and 369 mg/kg, respectively. Both of these samples were taken from 20 to 22 feet bgs. DRO was detected in groundwater samples from monitoring wells B2, B4, B6, and B7 with the results 42.4 mg/l, 0.578 mg/l, 2.18 mg/l, and 4.83 mg/l, respectively. The groundwater cleanup level for DRO is 1.5 mg/l. Soil and groundwater is impacted on site above cleanup levels. Contamination is migrating off-site. Evidence indicates a continuing source in the vicinity of the former UST location. Groundwater flow direction changes. Data resulting from this characterization suggest the possibility of a second off-site source to the northeast of the subject site. Further investigation of this possibility is warranted. ADEC also requested quarterly monitoring, product recovery, and installation of additional monitoring wells. Work plan and schedule to be submitted by July 15, 2002. Beatrice Egbejimba
6/27/2002 Update or Other Action ADEC waived the requirement to install additional monitoring wells after discussing the issue with the consultant. Request will be reviewed after additional monitoring of on-site wells. Beatrice Egbejimba
7/1/2002 Update or Other Action Received a cc of a letter sent 6/11/02 from Kay Rawlings of the Department of Law to the Lori Barnett with a Bill for Collection paid by the RP for the period 11/16/01 through 3/31/02. Beatrice Egbejimba
1/13/2003 Update or Other Action ADEC received letter from Department of Law indicating that a check on behalf of ADEC was received from The Salvation Army for cost recovery ($293.13). Beatrice Egbejimba
1/24/2003 Update or Other Action ADEC called Matt Hemry of Shannon & Wilson regarding quarterly monitoring scheduled for July 2002. He said that the monitoring event didn’t take place as planned because of lack of funding from the RP. A call to the RP revealed that the Anchorage office of the Salvation Army was not aware that Shannon & Wilson’s contract had been terminated by their risk assessment group at the Salvation Army headquarters. More information will be provided on 27/01/03 by the Anchorage Salvation Army after consultations with risk assessors. Beatrice Egbejimba
2/3/2003 Update or Other Action Received a cc of a letter sent 1/31/03 from Kay Rawlings of the Department of Law to the Lori Barnett with a Bill for Collection paid by the RP for the period 4/1/02 through 6/30/02. Beatrice Egbejimba
9/28/2004 Update or Other Action A letter was sent this date indicating that no ground water monitoring events have been received since 2002. The CSP requested that if any monitoring events have been conducted since this date that you forward them to the CSP no later than 1/15 /05. David Allen

5/19/2005 Update or Other Action The CSP received a letter from the Salvation Army dated 5/13/05 indicating that the Salvation Army has contracted with Shannon & Wilson to begin further ground water sampling at the site. An attached letter from the Salvation Army to Shannon & Wilson dated 3/28/05 verifies contract approval between the Salvation Army and Shannon & Wilson. The Salvation Army has been billed for work performed by Shannon and WIlson in the spring of 2005 and Mr. Turker was supposed to contact the CSP regarding related work. Bill Petrik
3/30/2007 Update or Other Action Staff reassigned from Sundet to Petrik. Aggie Blandford
2/25/2008 GIS Position Updated Used web resources and site map to update latitude and longitude from erroneous address matching method. Used TopoZone Pro at 1:2,952 scale satellite photography plotted on a large scale map, NAD 83. Location was corroborated by using Goggle Maps. Bill Petrik
2/25/2008 Exposure Tracking Model Ranking Initial ranking with ETM completed. Bill Petrik
3/26/2008 Site Characterization Report Approved Reviewed a copy of the Shannon & Wilson, Inc. report "April 2005 Groundwater monitoring Event, 1001 C Street, Anchorage, Alaska" dated 6/13/05 and received by the program on 3/7/08. A product recovery test was conducted and DRO sampling of MWs B2MW through B7MW occurred on 4/8/05. B2MW and B7MW had a heavy sheen but no measurable product; ~0.25” of product was measured in B6MW and after 1.5 hours of bailing the product level reduced to 0.1”. No other wells were measured for product on this date. A sheen was noted on the purge water from B2MW, B4MW, B6MW, and B7MW prior to sampling. The purge water was picked up by Emerald Alaska for treatment and disposal on 6/13/05. The GW flow direction was south-southwest with a gradient of less than one percent. DRO was not detected in B3MW and B5MW but was above cleanup levels in the remaining wells other than B4MW, with the highest value 96.6 mg/l. It appears that B2MW and B4MW have decreasing DRO trends (free-phase to 26 mg/l and 61.3 mg/l to less than 1 mg/l, respectively) but B6MW and B7MW have increasing trends (2.18 mg/l to 96.6 mg/l and 4.83 mg/l to 60.0 mg/l, respectively). DRO levels in B3MW and B5MW have been either ND or below cleanup levels for each sampling event. Bill Petrik
4/10/2008 Update or Other Action Reviewed a copy of a cc'd letter to Devra Hayes from Pam Post, Department of Law (DOL), dated 4/9/08 the CSP received indicating that the DOL received a cost recovery check from the RP. The latest Bills for Collection (CO25123, SPAR07316, SPAR7639, and SPAR08508) to the RP were related to the cost recovery periods of 1/16/01 through 4/30/01, 1/16/03 through 7/31/06, 3/1/07 through 3/15/07, and 2/1/08 through 2/29/08, respectively. Bill Petrik
7/28/2008 Update or Other Action The Contaminated Sites Program (CSP) sent a letter to the responsible party (RP). The letter provided a detailed summary of the site history to set the background, refuted the claims that the RP is making regarding both that they are not responsible as well as the problem is caused by an off-site source, and requested a work plan based on review of file documents and interpretation of site reports. A response was requested by 9/29/08. Bill Petrik
5/11/2009 Update or Other Action A letter was sent by Contaminated Sites Program (CSP) staff reminding the responsible party (RP) that the CSP has not yet received any communication from The Salvation Army, the RP, in response to a letter the CSP sent July 28, 2008. The letter requested a work plan addressing the site contamination issues to be submitted to the CSP by September 29, 2008. The CSP sent this letter Certified Mail, Return Receipt Requested and requested a written response within 30 days of receipt of the letter. (Petrik) Bill Petrik
9/1/2010 Update or Other Action The Contaminated Sites Program (CSP) sent a letter this date to the responsible party indicating that the CSP has not had any communication from them in response to its letters requesting a work plan initially on July 28, 2008 and reiterated on May 11, 2009. The recent CSP letter sent this date requested a written response within 30 days of receipt of the letter requesting a site status and update for requested site work. Bill Petrik
7/18/2011 Update or Other Action Letter received from Salvation Army in response to recent contact by DEC PM. Meeting scheduled for 7/19/11 to discuss site status Bill O'Connell
10/5/2011 Document, Report, or Work plan Review - other Reviewed work plan for groundwater monitoring and free product recovery at 1001 C Street. Product levels will be measured in each of the 6 wells at the site, and where product levels are greater than 0.5 inches, a product recovery test will be conducted over a two hour period. Groundwater samples will be collected fronm all wells where product is absent, and a level loop survey will be completed to evaluate groundwater flow direction. Bill O'Connell
3/1/2012 Document, Report, or Work plan Review - other Reviewed 2011 Groundwater Monitoring Report for 1001 C Street. Water and product levels were measured in wells B2MW, B3MW, B4MW, B6MW, and B7MW. B5MW could not be located. Free phase product was found in wells B2MW at 1.34 feet thick, B3MW at 1.43 feet thick, B6MW at 0.42 feet thick, and B7MW at 1.53 feet thick. This is the first instance of product in B3MW, which previously did not contain contaminants above Table C cleanup Levels. The product found in wells B2MW and B3MW nearest the former fuel tank was reddish in color, whereas the product found in B6MW and B7MW was yellow in color, suggesting the potential for offsite source areas to be impacting the property. A groundwater sample was collected from B4MW. DRO was detected at 4.91 mg/l, BTEX was not detected. The presence of free phase product precluded the accurate calculation of groundwater flow direction, but based on the correction of groundwater levels that accounts for the specific gravity of the product, groundwater is indicated to be flowing to the south-southeast, which is consistent with previous measurements. Groundwater levels were lower than in previous sampling events, which may be contributing to the presence of free product in the wells and the increase in contaminant concentrations in B4MW. Bill O'Connell
8/2/2012 Document, Report, or Work plan Review - other Reviewed Work Plan for Well Installation, Product Recovery, and Groundwater Monitoring at 1001 C Street. Activities proposed for 2012 include fuel fingerprinting of NAPL, product recovery efforts from wells where product is present, groundwater sampling at wells with no product, a horizontal and vertical well survey, and a drinking water well search. Three new groundwater monitoring wells will be installed and sampled and up to two soil samples will be collected per borehole prior to well installation. Soil and groundwater samples will be analyzed for DRO, RRO, GRO, and BTEX. Bill O'Connell

3/17/2014 Site Characterization Report Approved One groundwater sample and one filed duplicate sample were collected from groundwater monitoring well B8MW. The groundwater was analyzed for GRO, BTEX, DRO, and RRO. Concentrations were below cleanup levels. Depth to groundwater and depth to product was conducted on all the groundwater monitoring wells. Well B6MW was the only well to contain a measurable amount of product, 0.01 foot. Based on the last groundwater monitoring and product recovery event, CSP is not requiring a remedial action plan at this time; however, CSP is requiring quarterly groundwater monitoring and/or product recovery for a period of two years, after which this requirement will be re-evaluated. CSP requests that a work plan be submitted by May 15, 2014, including a schedule for when the work will be conducted. CSP requests that product monitoring and/or product recovery continues for monitoring wells B6MW and B7MW. If product is recoverable, please have the light non-aqueous phase liquid fingerprinted to evaluate the source of the product Katrina Chambon
5/23/2014 Document, Report, or Work plan Review - other Reviewed Work Plan for Quarterly Groundwater Monitoring Well Sampling and Product Recovery for the former Salvation Army Property, 1001 C Street. The objectives are to evaluate the plume stability and document contaminant trends, recover free product to the extent practicable, and perform fingerprint analysis on product that may be present at the site to evaluate potential source areas. In previous events, free product has only been present in recoverable amounts during periods of low groundwater. Groundwater samples will be collected from wells B2MW, B3MW, B4MW, B5MW, and B8Mw, assuming free product is not present. Wells B6MW and B7MW will be evaluated for the presence of free product but not sampled as it is suspected that contamination in these wells is from an offsite source area. Bill O'Connell
3/16/2015 Site Characterization Report Approved Reviewed the 2014 quarterly Groundwater Monitoring and Product Recovery report. The wells were sampled in the three quarters (May, September, and November). During each of the events, groundwater samples were collected from B2MW, B3MW, B4MW, B5MW, B8MW and analyzed for diesel range organics (DRO). All samples collected in the three quarters (except at B8MW in May and November and B3MW in May) exceeded Table C groundwater cleanup levels for DRO. B6MW had the only measurable product (ranging from 0.01 feet to 0.06). There was not enough product in B6MW an no product in B3MW during the three events to collect samples for fingerprinting.

7/1/2016 Meeting or Teleconference Held Met with the Salvation Army and their consultant to discuss the current site conditions in response to the April 7, 2016 Work Plan submittal. Proposed scope of work from the work plan did not appear to address the potential off-site source adequately to make any conclusions regarding contamination source origin. The next step is to meet with the neighbor property owner to seek permission to expand off-site investigative work onto the neighbor property. Darren Mulkey
12/22/2016 Document, Report, or Work plan Review - other Reviewed the Former Salvation Army Property - 12/19/16 - Shannon & Wilson report, Investigation of historical heat source for garage structure, 1001 C Street, Anchorage, Alaska. The study was conducted to assess if there may be additional sources that may be contributing to contamination that was discovered on this site. The structure is currently heated by a natural gas fired unit heater that was installed in 1995. There was no evidence of an above ground or below ground heating oil tank observed during the investigation. There is no evidence of a historic heating source exhaust vent or fuel source plumbing associated with the structure. There is not a floor drain in the concrete floor of the structure. No information was discovered for a previous heating source prior to the installation of the natural gas heater installed in 1995. Darren Mulkey

4/17/2017 Document, Report, or Work plan Review - other Reviewed Work Plan for Additional Site Characterization Activities. Scope of work includes installation and sampling of one upgradient groundwater monitoring well at 236 West 10th Ave, sampling of existing monitoring wells, evaluation/recovery of free product, if present from offsite and onsite wells for comparison purposes, a level-loop survey, investigation of a potential fuel source for the garage onsite, and a geophysical survey and soil sampling to identify potential heating oil UST at 236 West 10th Ave. At the onsite garage, historical air photos will be reviewed and electromagnetic and ground-penetrating radar surveys will be conducted to evaluate for the presence of a heating oil tank in this vicinity. At 236 West 10th Ave, a geophysical survey will also be conducted to look for a potential historic heating oil tank. Bill O'Connell

2/28/2018 Document, Report, or Work plan Review - other Reviewed Additional Site Characterization Report for 1001 C Street. The objective of the additional characterization was to evaluate a potential off-property source on the property to the east, collect product samples for fingerprinting, evaluate a potential on-property source at the garage building, sample groundwater and conduct a level loop survey. Due to the presence of free product along the southern edge of the site, it has been suggested that a second source may be located on the property to the east at 236 west 10th Ave. A ground penetrating radar survey was conducted at the suspected location of a former heating oil tank. The survey did not indicate the presence of a buried tank. Follow up conversations with the previous owner indicated a heating oil tank was present at this location, but was removed in the 1970’s. In addition to the GPR survey, a single monitoring well, B9MW, was installed along the eastern edge of 2369 west 10th. The soil sample collected from this borehole contained DRO up to 3,880 mg/kg at 22.5 – 24.5 feet bgs. The sample from 5-7 feet bgs contained DRO at 44.9 mg/kg. An electromagnetic survey conducted at the onsite garage building, as well as a historical air photo review did not indicate any source areas near the garage. Groundwater samples were collected from seven wells, both on the 1001 C street property as well as off-property. The new well, B9MW, contained DRO at 3.53 mg/l and well B7 also located on the 236 West 10th Ave property contained DRO at 5.67 mg/l. 1001 C street source area well contained DRO a 1.54 mg/l, which is significantly lower than previous results. LNAPL was present in well B6MW, but not enough for fingerprinting. Bill O'Connell
