Dear Resident,

As promised, this week’s update will focus on the Well Field Drilling Plan, which commenced yesterday and will take place over the next several weeks.

Before I get into the details of the plan, I would like to point out that the drilling of wells will enable the collection of gas that has not been collected for the past several months due to the inoperability of the existing gas collection system. The drilling will allow us to remove leachate from the landfill through the combination pumps and pipes that will be put in place in the wells.

When finished, it is expected that the amount of gas that will be collected will double that which is currently being removed; and that we will be removing more than 35,000 gallons per day of leachate which will be pumped to storage tanks and hauled off-site. This should make a noticeable difference in the reduction of odors.

The County will be spending approximately $2.6 million to drill more than 3,500 feet of wells, which will then be tied into a Landfill Gas Collection System (LGCS) and is expected to result in the collection of twice as much methane gas from the landfill compared to the amount that is currently collected. In addition, the LGCS will be equipped with pipes and pumps that will be used to drain liquid (leachate) from the landfill.

It is anticipated that with the installation of the pumps for the leachate, that the equipment will extract approximately 35-40,000 gallons of liquid per day and that liquid will be stored in new storage tanks placed on site during the project. Those tanks will be emptied into tanker trucks and hauled off-site to wastewater treatment plants.

During the drilling of the wells, anticipated to be between 30 and 50 wells depending on the depth of drilling that is necessary to reach gas and leachate, an odor control plan has been established. It is considered to be a three point defense against the spread of odors into the neighborhoods, east and northeast of the landfill.

The first point of defense will be the use of Neutralene in a pelletized form that is directly applied to the material that is being drilled and removed.

The second point of defense against the odors will be the use of a fogging system, directly next to the material that is being drilled and removed, in order to break down the odor at the source.

The third point of defense will be to continue the perimeter vapor system, which has been working over the past two weeks. With the five working stations on the perimeter, combined with the direct application and the fogging system, we believe that this will give us the best results that can be expected.

The drilling will take place probably through the month of April due to the number of wells that will be drilled. During this period of time, it should be understood that when a well is drilled, it will be closed within a day containing the leachate pipe, the gas pipe and the equipment to seal the well and enable it to be connected to the overall LGCS.

As the drilling progresses, the odors will continuously be monitored. I will continue to send you updates directly and the County website will be updated as well.

As always, if you have any questions or concerns, please do not hesitate to send them to me directly.

Sincerely,

Tom Arnone
Freeholder Director
