A section in the town has had to remain close since 2014 due to the town not being able to find the source of the pollution. Additionally, a portion of Crockett Cove is closed due to the possibility of upstream beaver dam. In order to solve the root of these problems DNA testing can help in determining. This issue is of importance because long Cove’s clam flats are on of the main clamming areas on the island with clamming having a large impact on the economy. The goal of Deer Isle-Stonington Shellfish Conservation Committee is to have sustainable commercial shellfish harvesting so that those who do harvest can make a good living.
