Environmental Testing

Organics: Volatiles, Semi-volatiles, PCB/Pesticides, Explosives, Herbicides, TPH (GRO, DRO, ERO) using the analytical techniques of GC, GC/MS, and HPLC.

Metals: Total/Dissolved/Leachable Metals including RCRA analytes, CWA analytes, SDWA analytes, Hexavalent Chromium, and Low Level Mercury using the analytical techniques of ICP, ICP-MS, Cold Vapor Absorption, and Cold Vapor Fluorescence.

General / Physical Testing: Commonly referred to as “Wet Chemistry”, we have the capability of measuring an extensive list of anions and physical characteristics using gravimetric, colorimetric, titrimetric, and potentiometric techniques.

TCLP/SPLP: These leachable procedures, as well as other program specific procedures are part of the routine testing performed in the Organics, Metals, and General Chemistry departments.

Air: Multiple air monitoring methods are routinely performed. Accredited analyses for Volatiles (TO-15), PAHs/Semi-volatiles (TO-13), Formaldehyde (TO-11), and Metals (NIOSH 6009, 7300, 7600) are available.

Field Services: Supported by an acclaimed Client Services team, the Chicagoland Division's Field Services team has the capability to collect samples in support of NPDES, Stormwater, SDWA, and RCRA requirements, as well as Flow studies and other specialized needs. Services range from simple courier service to critical “Clean Hands, Dirty Hands” techniques for low level metals determinations.

• Special Studies: Throughout the years, Microbac has assisted with numerous bench studies evaluating different operations such as chemical oxidation treatment, chemical treatability, bioremediation, and sterilization procedures. The Chicagoland Division can assist with specialized environmental services requests.

Food Safety

Food Testing: Food and food-related product testing for Microbiological agents is a specialty at the Chicagoland Division.

Store / HACCP Inspections: Trained sanitarians are available to provide consulting services and sample collection in support of Hazard Analysis Critical Control Point efforts and Safe Quality Food (SQF©) certification.

Microbiology: Aerobic Plate Count, Anaerobic Plate Count, Total Coliform, Fecal Coliform, E. coli, Listeria, Salmonella, Legionella, Staphylococcus aureus, Yeast & Mold/Fungi, Spoilage Organisms, CEA . These organisms and groups are routinely evaluated using various techniques, including conventional plating, membrane filtration, and Polymerase Chain Reaction (PCR).

• Food Chemistry: Through the Microbac network, extensive food chemistry, nutritional labeling and advanced testing are available.
