Thomas McFarland Jr. is charged with unlawful discharge of a pollutant and unlawful disposal of regulated medical waste.
Prosecutors allege the 59-year-old Wynnewood, Pa., resident, who owns a house in Middle Township, dumped a bag of waste from his dental practice off a boat into Townsend Inlet.
The debris, including 260 dental-type needles, washed up along a stretch of beach the next day.
Authorities say McFarland went to the Avalon Police Department and admitted dumping the waste more than a week later.
