Pig Monitoring Well Skimming Sock

We use these skimming socks at several underground storage tank sites across North Carolina for passive free product recovery. These monitoring well skimming socks work perfectly in 2" diameter or larger wells and can absorb a large a significant amount of product.

New Pig Skimming Sock

These oil only absorbent socks have exceeded my expectations for continued passive recovery of free product from environmental monitoring wells. These socks allow us to recover free product (and only free product, no water) from wells for an entire month, instead of just when technicians are present during site visits. They hold up well under conditions of high VOC's and removal following saturation.

Pig Monitoring Well Sock

The oil absorbent monitoring well socks work great. The amount of oil retained is amazing. They seem to even draw oil into the well. WELL DONE!!

By Fred


Great for Diesel Fuel Recovery

I am using the Monitoring Well Skimming Socks to recover diesel fuel from an underground tank leak, in small diameter wells and sumps. The socks absorb the diesel efficiently and at a lower cost than most of the alternative methods. Keeping them in the wells helps to draw the fuel from the soil. Their use also greatly reduces the volume of contaminated water generated for disposal.

Durable Monitoring Well Sock

The best monitoring well sock on the market. Very durable, doesn't break apart after wringing a couple of times. Easy to use and really absorbs the oil and not water unlike other similar products claim. Thanks Pig
