Kenneth Sansone


Ken Sansone, a partner with SL Environmental Law Group PC, exclusively represents water suppliers in contamination lawsuits, including claims over PFAS and 1,2,3 trichloropropane, or “TCP.”  He has obtained more than $125 million in recoveries for water systems to treat TCP, a toxic contaminant from defective pesticides sold by Shell Oil and Dow Chemical.

Ken serves as lead trial and appellate counsel to the City of Pomona, and, in September 2021, obtained a $48M jury verdict for the City for the costs of cleaning up perchlorate contamination from the use of tainted fertilizer products made by SQM, a multinational mining company.

Prior to joining SL, Ken served as an Assistant Attorney General for the State of New Hampshire.  He has more than 20 years of experience handling complex civil and criminal cases in federal and state trial and appellate courts.
