Other:
A.
Air Sparge Wells
1.
Design Goals:
Placed perpendicular to direction of ground water flow and in vicinity of TCE highs.
Cycle wells to insure contaminated ground water does not flow around wells.
Not run during summer season due to low levels of TCE detected.

b.
Pipe Diameter:
2 in
c.
Depth:
50 ft
d.
Screen Interval:
