2.2 Planning Section
|
|
|
|
2.2.1 Anticipated Activities
Preparation of an Action Memorandum to fund providing a deeper well or whole house treatment systems for affected residents.
Conduct a ground water investigation in early summer to determine source of the contamination and ground water flow.
Additional residential wells will be sampled as necessary.
Conduct vapor intrusion sampling in the homes in the affected area.
2.2.1.1 Planned Response Activities
Additional residential well sampling at homes in town as needed or requested Conduct vapor intrusion sampling inside the homes in the affected area.
Conduct ground water investigation to determine the source of the contamination.
2.2.1.2 Next Steps
Prepare and submitt an Action Memorandum to provide an alternate water supply or whole house filters for the affected residents. One option includes a deeper well as a source for residential water supply. Also, whole house carbon and air stripping treatment units to remove the Volatile Organic compounds could be utilized.
2.2.2 Issues
The township operates a deep well at Thompson Park which was installed by Wedron Silica. USEPA has requested that the Township consider utilizing the well to provide water to the 4 affected residents. The Township has said no to the proposal based on "potential Liability".
