HP Environmental to Celebrate 30th Anniversary in 2021


We are celebrating our 30th anniversary in 2021. What started out as a small environmental laboratory has now become an established industry leader in Industrial Hygiene, Site Assessment, Microbiology, Chemistry, and Building Science.

We thank everyone that has been a part of our journey over the last 30 years — both clients and friends — and look forward to serving your environmental needs for another 30 years and more.

The History of HP Environmental

HP ENVIRONMENTAL, Inc. was founded in 1991 by R. Hugh Granger, Ph.D., and Piotr Chmielinski, M.S., CIH, to provide technical expertise in the increasingly diverse sciences needed to understand and control human exposure to environmental and industrial hazards.  

Since its founding, HPE has grown in size and stature and is now widely recognized for its leadership in the environmental sciences. In 1993, HP Environmental purchased and occupied a 7,500 square foot office, conference and laboratory facility near Washington, D.C.’s Dulles International Airport.  The laboratory is located in the heart of Fairfax County’s technology corridor and is convenient to most major metropolitan areas of Maryland, Virginia, West Virginia and Washington, D.C.

From here, the team quickly grew to include a variety of environmental and laboratory sciences. We added experts from a variety of fields, including geologists, environmental engineers, industrial hygienists, safety professionals, home inspectors, chemists, and more.

Today, HP ENVIRONMENTAL has become an industry leader in providing innovative, environmental expertise to clients large and small not only in our own DC-area backyard but across the country.

We thank everyone that has worked with us over the years and look forward to continuing this important work together in the future.
