TMI Analytical Services is a small environmental testing laboratory, accredited by the Illinois Department of Public Health (IDPH) to perform analysis of drinking water for the presence/absence and quantification of coliforms and E. coli within samples, using ONPG-MUG and membrane filtration analyses. We are also able to perform quantification of other bacteria in waste water and solid samples. In addition, we are accredited by the American Industrial Hygience Association (AIHA) to perform analysis of air, bulk, and swab samples for identification and enumeration of fungi. Our laboratory works with environmental engineering firms, certified mold inspectors, municipal water department personnel, and individuals for sample collection.
