Abstract: | A fundamental question reported in hundreds of court decisions and evaluated every day by claims adjusters is whether a constituent that caused injury and damage is a “pollutant.” If yes, the claim will most often not be covered under general liability, professional, property, umbrella, or other policies because of the applicability of a pollution exclusion. Based upon our review of 200 cases, we determined that in 140, or 70 percent of the time, the constituent was considered a “pollutant” and the insurance claim was denied. In order to have insurance for “irritants” or “pollutants,” an insured must obtain specific pollution coverage. |
