Section 1: System Description
Function and Theory
The Geotech Product Recovery Canister (PRC) is a passive, skimmer device designed to
recover light floating hydrocarbons (such as gasoline and diesel fuel) from the ground
water in wells that are 2 inches (5cm) and larger.
Featuring a floating oleophilic/hydrophobic intake assembly, the skimmer can
automatically collect and skim floating product down to a sheen. Standard 2” skimmers
provide 12” (30cm) of intake travel and standard 4” skimmers provide upto 16” (40cm) of
intake travel, to accommodate water fluctuations. The unit is suspended in the well at the
desired recovery depth by the 25 feet (7.6m) of supplied stainless steel suspension cable.
System Components
A PRC consists of two (2) major components; a product skimmer assembly and a
collection canister (as shown in Figures 1-1 through 1-3). On the 4” model, the skimmer
assembly is protected by a slotted screen which pre-filters the incoming product and
protects the intake assembly from damage. The skimmer assembly collects free product
and passes it through a coiled hose to the collection canister. Recovered product is
evacuated by removing the PRC from the well and opening the drain on the bottom of the
device.
Increased capacity collection canisters are available and easily installed by simply
unscrewing the collection canister section and replacing it with a larger collection canister
and weight assembly. When going from smaller to larger collection canisters,
consideration must be made for weight. Going from larger to smaller is not a problem.

Section 2: System Installation and Operation
To install the PRC first measure the water and product levels with an Interface Probe
(Geotech can provide you with a variety of Interface Probes for all applications).
Typically, the PRC is set so that the intake assembly is placed at the midpoint of its travel
to allow for water table fluctuation in both directions (see Section 6 for an example of a
PRC in the well). To set the intake assembly at the midpoint of travel, measure from the
top centralizer (2” skimmer), or top cap (4” skimmer) on the PRC and along the
suspension cord, the same distance as the water level reading taken with an Interface
Probe, then subtract 6 inches (15cm). Suspend the PRC from the wellhead to this point.
To empty the collection canister, simply pull the PRC up from the well, open the drain
valve (by applying a downward pulling force on the valve sleeve – like a water bottle) and
transfer the recovered product into an approved container.
When re-installing, verify that the intake assembly will be set within its range of travel (as
describe above), and that the drain valve is completely closed to avoid the possibility of
water entering the canister. Figure 2-1 shows an example of the drain valve open and
closed.
Figure 2-1 Drain valve operation
Prior to installation, the oleophilic/hydrophobic screen intake must be
“conditioned”, or primed. To accomplish this, use diesel fuel or similar
hydrocarbon to saturate the screen portion of the intake assembly (as
shown in the figures found in Section 7). The optimum fluid would be
the downwell hydrocarbons to be recovered. Take care to avoid
damaging the intake assembly.

Section 3: System Maintenance
With proper maintenance the Geotech PRC will provide years of reliable service. When
emptying the canister, these simple maintenance steps can be taken to assure its
reliability.
1. Inspect the product skimmer assembly for signs of physical damage. Scrapes or
dents in the screen intake may cause the skimmer to take on water. If such
damage is found, a new replacement intake assembly may be necessary.
2. Inspect the tubing coil for physical damage or obstructions, such as kinks.
Replace the tubing coil as necessary.
3. Inspect the collection canister for physical damage such as cracks. Replace as
necessary.
4. To clean the intake assembly screen intake, use a very soft bristle paint brush
and fresh diesel fuel or the type of product being recovered. Typically, this type of
maintenance should only be performed when the screen is obstructed with
emulsified product or other debris. Take care not to dent or scratch the screen
intake.
5. Use diesel fuel or similar hydrocarbon to saturate the screen portion of the
intake. The optimum fluid would be the downwell hydrocarbons to be recovered.
Take care to avoid damaging the screen intake.

Section 4: System Troubleshooting
Problem: The PRC recovers only water.
Solutions:
1. The PRC is set too low in the well restricting the travel of the intake assembly.
2. Drain the collection canister completely, allow the screen intake to dry, re-prime
the screen, then reset the PRC so that the water level fluctuation is within the
travel range of the intake assembly.
Problem: The water level has risen past the top of the travel range of the intake
assembly.
Solution:
Drain the collection canister completely, allow the screen intake to dry, re-prime the
screen, then reset the PRC so that the water level fluctuation is within the travel range of
the intake assembly.
Problem: The drain valve is not fully closed.
Solution:
Empty the collection canister (as described in Section 2), and then close the drain valve
by pushing up on the outer sleeve of the drain valve until it stops.
Problem: There is a mechanical malfunction or a leak has developed.
Solution:
Call Geotech Environmental Equipment Inc. at 1-800-833-7958 for assistance.
Problem: The skimmer intake is not recovering product.
Solutions:
1. There is no product to recover.
2. Check, and periodically monitor, the product layer thickness.
If the water level has risen above the travel range of the intake
assembly at any time between site visits, the skimmer
assembly and collection canister will fill up with water and
displace any collected product. It will remain this way until
reset, even if the water level falls back within the travel range of
the intake assembly.
8
Problem: The skimmer is set too high.
Solution:
Recheck the water and product levels and reset the skimmer assembly (use the
installation procedures described in Section 2).
Problem: The canister vent is blocked.
Solution:
Make sure that the holes in the suspension fitting are clear of debris. The PRC will not
operate if these holes are plugged.
Problem: The intake assembly is obstructed or the coiled product hose is kinked.
Solution:
Refer to Section 3, “System Maintenance”.
