When several major oil companies agreed earlier this month to pay nearly $424 million to settle a federal lawsuit brought by scores of water providers claiming damages from the gasoline additive M.T.B.E., one Long Island provider took the largest share by far.
The Suffolk County Water Authority in Oakdale, which supplies water to more than 1.1 million customers in the county, walked away with $73.4 million of the settlement. That figure was by far the highest among the Long Island providers and the other more than 150 water companies from 17 states.
