HAPPY NEW YEAR!

PSA had a great year in 2007 and looks forward to an exciting 2008.  In 2007 PSA made some additions to equipment and performed some exciting projects for new clients.

EQUIPMENT:

In the fall of 2007 PSA acquired a used 6620 track unit which will complete our list of Geoprobe® units for the near future.  With this new purchase PSA will now have the ability to auger and install 1-inch wells in difficult and off road areas previously not possible with our stand 6600 truck unit.  PSA has been working quickly to outfit and prepare this unit with many of the aminities to make it more user friendly and more efficient for our staff to perform tasks in the field.  Those include a custom 50-gallon aluminum water tank mounted to the rear of the unit with on demand water sprayer, fold down work stations and rod holders for ease of use for both staff and client, tool holders and our “quick” vise attachment, liner box carrier and lastly upgrades to the winch mast for faster setup and take down while drilling or probing.

To haul this new machine PSA purchased a 2004 F-350 quad cab dually and brand new 14K Lbs. flatbed trailer.  PSA then installed a Knapheide topper to carry all our tooling and supplies to provide the best operations a field.

This new unit will be utilized as our primary drilling rig capable of installing 2-inch PVC/Stainless monitoring/injection wells.  Let us help you utilize this awesome capability on your next project.

EXCITING PROJECTS:

Since 1997 PSA has focused on the remediation industry as a primary sidebar to our typical sampling activities.  2007 saw some great opportunities to perform those injection activities.

Columbus, NE

PSA working with an EPA contractor performed potassium and sodium permanganate injections at 68-locations to depths of 65-feet.  A total of 156,400-gallons of product was injected to help remediate a former drycleaners TCE and degredation products contamination plume.  The project was completed in 45-days and  $12,000.00 under budget!

Private Site

PSA mixed and applied over 8,000 pounds of RegenOx® at 62-locations to depths of 32-feet.  The project was designed such that the contaminated are had been shored off with bridge pilings to bedrock, containing all the product within a constructed soil filled bathtub.  The project took just over 18-days given weather/ice delays and $4,000.00 under budget.

KEEPING UP WITH THE TIMES

In the environmental industry trends and technology is a full time business in and of itself.  PSA strives to maintain a good understanding of what is needed by clients and regulators alike.  Here in Missouri one of those is the implementation of soil gas monitoring.  The new MO RBCA program addresses the need for certain sites to have and acquire soil gas readings on an on-going basis.  PSA has kept on-top of this need by providing permanent soil gas monitoring points.  Similar in construction to a monitoring well these little gas sample wells are excellent in construction and ease of use for the client to return and sample as needed my these specific site monitoring criteria.  Set in a flush mount monitoring well vault a gas tight valve is connected to a 3/8”x ¼” polyethylene tubing.  The tubing runs down hole to a 6-inch or 18-inch .5” D stainless steel screen.  Set just like a well with a sand pack and grouted using high solids bentonite slurry the soil gas sample points make for fast and accurate sampling of a sites soil gas condition.  Typical installation of 4-8 points per day is typical depending on depth.  Using this method of soil gas sampling versus continual remobs to the site to acquire new “active” soil gas probes is much more cost effective over the coarse of sampling events needed.

MONITORING WELL ABANDONMENT

Given so many of the sites are now moving into a clean phase PSA has adapted and tooled up to provide clients with the best monitoring well abandonment capabilities possible.  Our quick extractor for PVC is light years ahead of other methods for removal of PVC wells.  1, 2 and 4-inch PVC wells are all possible with PSA’s quick extractor tooling.  Flush mount or above ground protective can removal is also made possible with specialized tools and fixtures.  Let PSA provide you with a quote for your monitoring well abandonments.
