Nassau County, New York
Nassau leftover cesspools sit on the North Shore (~40,000 residential systems). A firm is listed only when Nassau Consumer Affairs prints a Home Improvement license number and the street is North Shore / unsewered. The S.E.P.T.I.C. installer PDF names firms but does not print the number — the number is quoted from the Apex lookup. South and central Nassau is mostly sewered and is not padded.
