Tests on wastewater in an upscale Massachusetts ocean resort town have revealed unexpectedly high levels of cocaine – up to three times the national average.

The isolated island, located south-east of Martha’s Vineyard in the Atlantic Ocean, is an upscale and popular summer retreat for the prosperous, complete with sandy beaches, quaint cedar-shingled buildings and cobbled streets, and classic New England lighthouses and seafood.
