Recommendations
Implement recommendations in the DMF shellfish management plans for Areas MB5.2, MB5.4, and MB5.1.
Develop a monitoring plan and conduct bacteria sampling to evaluate effectiveness of point (Phase II stormwater permits) and non-point source pollution control activities and other actions and to assess the status of the Primary and Secondary Contact Recreational uses.
Support DMF efforts to improve availability/access (electronic or web site) to water quality and biological monitoring data collected from DMF shellfish sampling stations to assess the status of the Primary and Secondary Contact Recreational uses.
Work with NSRWA to implement a quality assurance component for their water quality monitoring program.
Collect and analyze estuarine and diadromous fishes from this segment of the North River to determine if mercury related to the Fireworks Site and the Indian Head River is impacting resident and migratory fishes if deemed necessary.
