In addition to the reports above, the links below are concise annual data summaries prepared by the NBC as handouts for meetings of the Rhode Island Environmental Monitoring Collaborative (https://www.rimonitoring.org/), of which the NBC is a proud member. The Director of Environmental Science and Compliance serves as the Vice Chair of this important organization that brings together stakeholders from academia, environmental groups and non-profits, and state and federal environmental management to discuss monitoring priorities and funding availability. The organization typically meets twice per year, with a spring meeting to discuss monitoring plans and a fall/winter meeting to discuss the past-year's findings.
