BACKGROUND: Source Environmental Sciences, Inc.

Source Environmental Sciences, Inc. was founded in 1984 by Jack Coblenz and several other environmental specialists from Dames & Moore, Inc. (a large multi-national environmental consulting firm). Since its founding, Source has concentrated on performing environmental consulting services for industrial and commercial clients in Texas and in nearby states. Over the years, Source has gained a reputation for providing very high quality services at fair and reasonable costs. As a result, Source grew rapidly into a firm of 50 employees.

In late 1990 Source was purchased by Team, Inc., a large nation-wide industrial services firm, where it became the Source Environmental Science Division of Team, Inc. The operations, services and staff of Source remained essentially unchanged and Jack Coblenz continued managing operations as President of the Source Division.

In 1995 having completed its contractual agreements with Team, Source was reformed as an independent environmental consulting firm and conveniently located its offices in the Galleria area of Houston, Texas, the heart of the city's commercial and retail activities. Source now has a modest size staff of highly qualified environmental experts. Source now prides itself as having over 100 clients for whom it performs the majority of their environmental services. These clients are mostly commercial and industrial firms, but Source has also successfully completed many environmental projects for various governmental clients at city, county and state agencies. The scope of this work and the variety of clients can be readily seen on the our list of recent projects.


Source is a veteran owned and operated small business enterprise and meets all requirements of the U.S. Small Business Administration's size standard.
