Case Closed: Verdict for City of Pomona in Water Contamination Case Upheld

After a 13-year legal battle,Pomona awarded its full past and future treatment costs: $30.28 million 

LOS ANGELES, CA, October 31, 2023 – After 13 years of hard-fought litigation, proceedings in the City of Pomona’s case against SQM North America Corporation seeking to recover for the costs of groundwater contamination caused by SQM’s defective fertilizer products have officially concluded, with SQM’s payment to the City in the sum of more than $30.2 million. This payment represents the City’s full costs, both those already incurred and those expected to be over the next 30 years, for treating perchlorate in its drinking water supplies, together with certain costs awarded by the court, and interested. SQM made the payment after the Federal Court of Appeals for the Ninth Circuit, in a May 2023 decision, upheld a September 2021 jury verdict in favor of the City. The jury found that defective perchlorate-tainted fertilizer sold by SQM, a subsidiary of multinational mining company Sociedad Química y Minera de Chile, for use in the City’s former citrus orchards had contaminated its drinking water wells with perchlorate, necessitating a specialized water treatment plant costing tens of millions of dollars to construct and operate.

Perchlorate is a toxic chemical that can be particularly harmful to children as it disrupts hormones needed for healthy growth and development. As a result, it is banned from drinking water supplies in California except at very low levels, and is also the subject of a pending nationwide drinking water standard under consideration by theEnvironmental Protection Agency. In 2010, the City retained SL EnvironmentalLaw Group (SL) and filed a products liability lawsuit against SQM seeking $30.2 million to recover past and future costs associated with investigating and remediating perchlorate contamination.

SL attorneys argued that SQM should take responsibility for the cost of the contamination cleanup caused by its defective products, as manufacturing methods available at the time the fertilizer was made could have removed the perchlorate from the fertilizer.After fighting through multiple appeals and trials, the City convinced theCourt of Appeals for the Ninth Circuit in Pasadena that the evidence supported the City’s claim and $30.2 million in damages.

Ken Sansone, senior partner at SLEnvironment Law Group who led the City’s efforts at trial and on appeal said[VMB1] , “The City of Pomona never gave up, and neither did our team of lawyers. I commend the resilience and tenacity of everyone involved in this fight to ensure that the polluters, not the taxpayers of Pomona, are held accountable for remediating perchlorate contamination.”
