The Flint, Mich., water crisis returned to the news recently as criminal charges were brought against additional government employees resulting from the crisis. Meanwhile, a federal court in Pennsylvania recently issued a ruling in an insurance case that, like Flint, related to alleged contamination in drinking water stemming from corroded pipes. The decision rejects two insurers’ attempts to avoid coverage and serves as a good reminder of some fundamental insurance law principles—the duty to defend is broad, ambiguous policy language usually is construed against the insurer, and policies should be interpreted in favor of their purpose to provide coverage. It is also a reminder that the pollution exclusion is not nearly as all-encompassing as insurers like to think it is.
