The April 2012 agreement with the Potentially Responsible Parties (GE and SI Group) for the construction and operation of the water treatment plant also required the companies to install five additional groundwater extraction wells along the western edge of the landfill (EW-4 to EW-8). The new extraction wells collect additional contaminated groundwater for treatment at the plant and are located closer to the landfill than the three pre-existing extraction wells. The first of the new extraction wells came online on July 6, 2015. Each of the remaining wells came online in four-week cycles. The fifth, and final, extraction well came online yesterday, October 26.

The EPA will hold a public information meeting for the Dewey Loeffel Landfill Superfund Site on Wednesday, November 4 in Nassau. See page 1 of the Fall 2015 Community Update for more meeting information: http://www3.epa.gov/region02/superfund/npl/dewey/pdf/deweyloeffel_communityupdate_fall2015_final_v2.pdf.

EPA Update on Treatment Plant at the Dewey Loeffel Landfill Superfund Site: September 1, 2015
 

The data from the sampling conducted on August 19, 2015 is now available on EPA’s Dewey Loeffel Landfill Superfund Site webpage. This sampling event occurred the day before the process began of replacing both carbon filter units in the plant.

On August 20, the first carbon filter unit (known as the lead) was replaced. The second carbon filter unit (known as the lag) was temporarily taken out of service on August 21, and then replaced on August 27. While the lag unit was out of service, discharge of treated water from the plant occurred after it had been processed through the specialized treatment system for 1,4-dioxane (the HiPOx unit) and the lead carbon filter unit. Data collected to date has demonstrated that the HiPOx unit is working effectively.

Both of the replacement carbon filter units are now in place and operational. The data reflecting the replacement of the first carbon filter unit will be available next week. The data reflecting the replacement of both units will be available the following week.

The startup of the new groundwater extraction wells also continues. The third of five new extraction wells (EW-4) was brought online on August 31.

EPA Update on Valley Stream Testing - August 19, 2015

 

Supervisor Fleming,

 

I am reaching out to provide you advance notification that GE and S.I. Group’s contractors will be conducting some investigation activities in Valley Stream starting on August 25. The investigation activities will include the installation of three staff gauges which are pipes that will be placed in the stream to measure water levels. There will also be field readings collected in the stream (every 50 feet) to assess water quality parameters.

 

These activities are associated with the landfill and groundwater investigation of the Dewey Loeffel Landfill Site. EPA has given GE and S.I. Group interim approval to conduct a limited set of tasks in advance of EPA’s approval of the Remedial Investigation/Feasibility Study Work Plan (RI/FS). As you are likely aware, some of the tasks detailed in the RI/FS work plan are constrained by the season and conditions so that is why EPA provided this interim approval of this work.  

 

This initial work is expected to completed in about 3 days. The start date is dependent upon GE and S.I. Group retaining access from the property owners. If the schedule changes I will provide you with an update. Please let me know if you have any questions.

EPA Update of Dewey Loeffel Landfill Superfund Site: August 18, 2015
 
The data from the sampling conducted on August 5, 2015 is now available on EPA’s Dewey Loeffel Landfill Superfund Site webpage.

On June 10, 2015, one of the two carbon filter units in the treatment plant was replaced to address a short-term increase in 1,4-dioxane (up to 6.6 parts per billion) in the treated discharge. Data collected after the carbon filter unit was replaced showed that the concentrations of 1,4-dioxane in the treated discharge had decreased.

Between July 22 and July 29, 2015, the concentration of 1,4-dioxane increased from 0.57 parts per billion to 1.3 parts per billion. Based on the data, the EPA has attributed this most recent increase to the carbon filter unit that was not replaced in June. To ensure that the plant continues to operate at maximum effectiveness, the EPA announced last week that both carbon filter units in the plant will be replaced beginning this Thursday, August 20, 2015. The most recent data for 1,4-dioxane (August 5, 2015), now available on the site webpage, is 2.5 parts per billion.

To prevent cross-contamination of the carbon filter units, the first carbon filter unit (known as the lead) will be replaced this Thursday, August 20. On Friday, August 21, the second carbon filter unit (known as the lag) will be taken out of service until it is replaced on Thursday, August 27. While the lag carbon filter unit is out of service, discharge of treated water from the plant will occur after it has been processed through the specialized treatment system for 1,4-dioxane (the HiPOx unit) and the lead carbon filtration unit. Data collected to date has demonstrated that the HiPOx unit is working effectively. Both carbon filtration units are scheduled to be operational by August 28th. The data reflecting this change-out of both carbon filters is expected to be available the week of September 7.

All of the data collected to date continues to meet the discharge limits set by the New York State Department of Environmental Conservation and show no detectable levels of most compounds tested for. EPA will continue its ongoing oversight of the treatment plant operations.

Subject: RE: Nassau Lake

Supervisor Fleming,

 

Yes, GE and their contractors have started the process to request access from property owners for only the Phase 1 portion of the Remedial Investigation for the surface water drainageways. This process can often take many weeks and months so they are trying to secure access so that sampling can begin in the fall, as discussed in the July 2015 project update.

 

I plan on being up in Nassau the evening of August 26th to meet with UNCAGED to discuss their comments on the Phase 1 Remedial Investigation Work Plan for surface drainageways and also the landfill and groundwater RI/FS Work Plan. UNCAGED previously indicated that the Town of Nassau may also attend that meeting. If you will not be participating in that meeting and have additional questions please let me know and we can set up a time for a discussion.  

 

Thanks,

EPA Update on Sampling of Treated Water from the Loeffel Superfund Site: June 16, 2015
TOWN NOTE: Please note that the discharge of 1,4-dioxane into the Valatie Kill has reached 6.6ppb.

EPA UPDATE -
The data from the sampling conducted on June 3, 2015 is now available on EPA’s Dewey Loeffel Landfill Superfund Site webpage.
 

The recent increase in 1,4-dioxane concentrations has been attributed to the carbon filtration system at the plant. To improve the carbon system’s effectiveness, one of the carbon filter units in the plant was replaced last week (June 10).

A sample of treated water was collected after the carbon filter unit was replaced (June 12) and those results are expected to be available next week.

The data show no detectable levels of most other compounds tested for.

EPA UPDATE – 8/31/2011

EPA recently provided an update on progress at the Dewey Loeffel site. As discussed in their last report, installation of the groundwater monitoring wells began in late June and was completed in mid-July. In August, geophysical evaluation began and further testing of the wells (including sampling) is underway. The groundwater evaluation is schedule to be completed by the end of September.

As you may recall, the Landfill Cap Investigation was initiated in May. The technical report with the results of the investigation is expected by the end of September and will be available on EPA’s website at http://www.epa.gov/region2/superfund/npl/dewey/.

A report summarizing the results of the groundwater investigations is expected at the end of this year. Additional groundwater investigations may be necessary and are dependent on the findings of the investigation.

 

 

The attachment represents a map with the well locations and properties identified for current EPA work on the Loeffel Site.  

EPA has placed 2 wells on property (A. Smith - Block 5 , Lot 20) .  Those are wells 3 and 5 on the attached map.   They have placed 3 wells on property (Block 5 , Lot 21).   Those are wells 1, 2, and 4. 

August 1, 2011 Update on the Loeffel Landfill

Attached is the May, 2011 Groundwater Sampling Event Monitoring Report completed by GE's consultant Tetra Tech Geo (formerly GeoTrans).  The report is dated July 28, 2011.  GE's consultant will conduct their fall groundwater monitoring well sampling in October.  As evidenced by sample results from OMW-222 and OMW-223 (all parameters were non-detect), the groundwater plume has not migrated further in that direction.  This sampling event is a separate effort from the residential well sampling which is conducted by GE's other consultant Arcadis.

 

Also, I would like to report that at the request of EPA, the DEC is now operating the off-site groundwater extraction wells.  You can expect that the number of tanker trips will increase considerably. EPA has completed the installation of five additional off-site monitoring wells and will be performing testing on them shortly.

Dear Community Members:

Please find information the Town has requested concerning the tanker trips and loads from the Loeffel Landfill by clicking the above link.  DEC reports that there were 14 tanker trips in the months of April and May.  Their claim is that the leachate composition has not changed.  Additionally, I want to advise you that EPA will begin the off-site monitoring well installation next week.  Their contractors are expected to begin efforts on June 20th.  The actual work is not scheduled to begin until the next day.   GE is also sending consultants out to conduct additional soil and sediment sampling in/near T11A beginning June 22nd.  This sampling is expected to take a few days.


Please let me know if you have any questions. 

Thank you and best regards.

Dave Fleming, Town Supervisor
