About ASI


About Analytical Services, Inc.

Analytical Services, Inc. (ASI) is a full service environmental microbiology laboratory that provides testing, consulting, research and expert witness services to clients throughout the United States and internationally.  

ASI projects range from routine compliance monitoring to investigative projects to research to special projects that incorporate multiple disciplines.  We routinely analyze water, wastewater / reclaimed water / stormwater, biosolids, sediments, and other matrices for pathogens and indicator microorganisms.  ASI has received samples from 48 states and 12 foreign countries. 

ASI is pleased to announce that our laboratory holds Primary NELAC accreditation from the New Hampshire Environmental Laboratory Accreditation Program (ELAP) for EPA Method 1623.1 in drinking water and non-potable water.  This certification covers the USEPA requirement for laboratories performing Cryptosporidium analyses for the second round of the Long Term 2 Enhanced Surface Water Treatment Rule (LT2 Round 2).  ASI also holds accreditation from numerous entities; including TNI/NELAP, US CDC and numerous states, for various parameters and matrices.  Please see Certifications or contact us for details.   

In 2014, ASI became part of the IEH Laboratories and Consulting Group, Inc., with corporate headquarters located in Lake Forest Park, WA.  While ASI's laboratory is still located in Williston, VT, joining IEH has increased our technical expertise, analytical capabilities, laboratory capacity and resources, especially with respect to molecular microbiology.
