Serving O’Fallon, IL

O’Fallon is a St. Clair County city of about sixteen square miles where Interstate 64, US 50 and IL 158 meet and a CSX line runs through. It treats its own wastewater but buys all of its drinking water. The city operates a 14.6 million gallon a day treatment plant under NPDES permit IL0021636, while finished water for 46,603 people arrives through exactly two custody transfer master meters from Illinois American Water, so the entire water accounting, loss analysis and billing of the city rests on the accuracy of those two meters. HSHS St. Elizabeth’s Hospital completed a 65.7 million dollar medical, surgical and emergency department expansion on St. Elizabeth Boulevard in February 2025, bringing new and relocated clinical equipment into service under its own commissioning and documentation requirements. Red-E-Mix runs a ready mixed concrete plant in the Commerce Plaza corridor and Jet Precast builds precast concrete products on West Third Street. Scott Air Force Base adjoins the city as its own separate census place. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because O’Fallon sits outside our Mid-Atlantic pickup radius, we serve St. Clair County through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments‍ ‍at your facility. Each calibration is performed against documented procedures, traced through NIST, and accompanied by an audit-ready certificate that supports AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems.
