The most critical element in meeting the objectives of a saturation field
monitoring effort is the successful determination of actual aerial
source/receptor patterns in the region of concern. Our key personnel
have over 20 years of applied experience in measuring such relationships
in a field operations environment. This experience involved the real-time
mapping of transport and dispersion patterns by measuring the downwind
concentrations of emissions around a known
source. Plume mapping projects
that our key people have managed and participated in include hundreds of
tracer tests in urban and rural environments, as well as, both ground and
airborne boundary layer pollution profiling projects utilizing tracers
of opportunity.
The Team's experience dates back almost three
decades to major projects mandated by federal, state, and local
districts to determine dispersion patterns around existing and proposed emission sources. The studies have ranged from multiple power plant, area source, line source and dispersion studies in California, Colorado, Nevada, Indiana, Illinois, Tennessee, Ohio, Missouri, South Carolina, Virginia and Washington DC. All these studies included making ground based measurements with up to 125 samplers to map the plume transport and dispersion. In addition, many smaller scale source/receptor reconciliation programs to quantify emissions from mining and material handling operations, vehicle emissions in tunnels, and urban source emission patterns have been conducted by our key personnel. Clients for whom the developed methodologies and technologies have been deployed include Southern California Edison, Ohio Edison, Savannah River Laboratory, Consolidated Edison, Pacific Gas and Electric, Exxon, Texaco, the California Air Resources Board, various State Air Pollution Control Districts, and many others.

Some of our recent projects include:

Satellite Site Operations for the California Regional PM10/PM2.5 Air Quality Study (CRPAQS)

Las Vegas Valley CO Saturation Study
