The companies, which deny the allegations, said that they expect to finalize a formal agreement by the second quarter of 2023.
Chemours said it would contribute half the agreed amount, while the remainder would be provided by DuPont and Corteva.
A first trial testing those claims against 3M Co. is scheduled to begin next week.
Chemours, DuPont and Corteva were originally included as defendants in that trial, but Gergel removed them from the proceedings last month.
The companies also face claims in other courts raised by individuals and by state attorneys general in California, Maryland, Washington and elsewhere.
