HAPPY NEW YEAR!

PSA had a great year in 2010 and looks forward to an exciting 2011.  In 2010 PSA made some additions to equipment and performed some exciting projects for new clients.

EQUIPMENT:

Already in 2011 PSA is moving forward with a new division of PSA that will be providing air-knifing / potholing services. PSA has acquired a Vacmaster system to provide this service.  PSA will be working quickly to train and obtain all necessary certifications to efficiently and cost effectively provide this new and exciting service as soon as possible. 

This new unit will be utilized as a utility clearing unit for sites requiring this value added service.

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.
