Missouri Hannibal Water Settlement Notes

  • Oliver Latta, et al. v. Hannibal Board of Public Works, et al.
  • Case No. 16SL-CC01881
  • Pending in the Circuit Court of the County of St. Louis, State of Missouri

Four named plaintiffs brought this class action lawsuit against the City of Hannibal, Missouri and the Hannibal Board of Public Works regarding the quality of water between September 2011 and February 2016.

Specifically, the plaintiffs alleges that the Hannibal defendants was negligent in supplying water “unfit for human consumption” because the water contained elevated levels of total trihalomethanes, a disinfection byproduct used during that time below EPA allowable limites. Some studies indicate their is higher chance of certain cancers due to exposure of excessive levels of the byproduct.

Under the terms of the settlement, the Hannibal defendants will pay a minimum of $5 million for water quality improvements, including installing a carbon water filtration system (estimated at over $14 million). The settlement will also payout $205,000 in a fund for residents who consumed the water over a period of three years. Members of this Class will need to submit a claim for reimbursement of out-of-pocket costs for a urinalysis for blood and urine cytology.

Hannibal denies the allegations and denies any wrongdoing.. Complete details about the case and settlement are provided on the Missouri Hannibal Water settlement website.
