What We Do

Region 3's Laboratory and Technical Services Branch (LTSB), housed in the EPA Environmental Science Center (ESC) in Fort Meade, Maryland, provides laboratory and technical services for Region 3's air, water and waste programs. The lab:

  • is responsible for analytical services, site/project level data quality assurance, data management and integration;
  • provides both routine and non-routine laboratory analysis; and
  • plays a major role in quality assurance of all Regional data collection and analysis.

The ESC is now certified as a LEED® Building.  The U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED®), is a certification program requiring applicants to demonstrate the building's operations as energy efficient and high performing.
