A semi-truck hauling a corrosive water treatment chemical leaked an estimated 300 gallons of product along South Street and Interstate 65 in Lafayette, Indiana, prompting a full hazardous materials response, a truck stop evacuation, and shelter-in-place advisories for nearby businesses. The leak began on the 3900 block of South Street near the Riviera Maya restaurant, and the truck continued east to I-65 before heading north. At approximately 6:54 p.m., the driver called 911 from Love's Truck Stop to report the leak after moving the trailer away from the heavily populated South Street corridor. Shipping documents and field testing identified the substance as AQUCAR™ GA 50 Water Treatment Microbiocide, carried in 16 intermediate bulk containers (IBCs). Incident Command determined that an emergency braking maneuver near I-65 mile marker 168 shifted the load and damaged one container. The Lafayette Fire Department, Lafayette Police Department, Tippecanoe County Emergency Management Agency (TEMA), and Indiana Department of Environmental Management (IDEM) neutralized pooled product with soda ash and diluted roadway residue with water. Officials confirmed no product entered any waterway or storm drain. Roadways and businesses reopened as areas were treated, with cleanup expected to finish by the end of the day on October 9.

Location and Infrastructure

South Street is a primary east-west corridor on Lafayette's southeast side, where it carries State Road 38 toward the Interstate 65 interchange. The 3900 block sits within a busy commercial stretch lined with restaurants, retail businesses, and service establishments, drawing steady passenger traffic throughout the day. Near the interchange, travel centers such as Love's Truck Stop attract a high volume of commercial vehicles entering and exiting I-65, which serves as one of Indiana's most heavily used freight routes between Indianapolis and Chicago. This blend of local shoppers, commuters, and long-haul trucks creates congestion at signalized intersections and interchange ramps, particularly during evening hours. Mile marker 168 lies near the State Road 38 interchange serving Lafayette. Commercial vehicles hauling regulated materials through this corridor are required to display hazard placards, which help first responders identify cargo risks.

Legal Rights and Considerations

Incidents involving commercial carriers and hazardous materials may implicate both Indiana law and federal regulations. Under Indiana's Comparative Fault Act (Indiana Code 34-51-2), a claimant may recover damages reduced by their percentage of fault, but recovery is barred if their fault exceeds 50 percent. Indiana generally imposes a two-year statute of limitations for personal injury and property damage claims (Indiana Code 34-11-2-4). Motor carriers transporting hazardous materials are subject to Federal Motor Carrier Safety Administration and Pipeline and Hazardous Materials Safety Administration rules, including cargo securement standards and elevated minimum financial responsibility requirements under 49 CFR Part 387. Those affected may have claims for property damage, vehicle damage from corrosive residue, medical expenses related to chemical exposure, lost wages, and business interruption losses. Documenting damage, retaining receipts, and obtaining official incident reports can be important. Individual circumstances vary, and this information is not legal advice.
