  Bureau of Marine Water Monitoring




Each year, the Bureau of Marine Water Monitoring (BMWM) updates the classification of New Jersey's coastal waters for shellfish harvesting. As the chart above shows, New Jersey has had a long history of improving the sanitary quality of its coastal waters These classifications are based on analysis of extensive sampling and pollution source surveys where actual and potential pollution sources are identified. The classifications represent a comprehensive assessment of the sanitary quality of New Jersey's coastal waters. The water classifications are:
