Welcome to Your Estuaries Partnership

The mission of Piscataqua Region Estuaries Partnership (PREP) is to protect and improve the water quality and overall health of the region’s two estuaries – Great Bay & Hampton-Seabrook. We monitor and research the region’s water ways, encourage all who live, work and play on the Seacoast to take actions to help protect and preserve the places we love, support development patterns that protect water quality, maintain open spaces and important habitat, and restore estuarine resources. Read more.

Science & Research

PREP’s core work includes our science, research and monitoring programs. We fund and coordinate scientific research projects and long-term monitoring to answer questions about the health of the estuaries and how they are changing over time. Our triennial  State of Our Estuaries reports explain the status and trends of environmental conditions in the estuaries. PREP also maintains an extensive Publications Library of research reports.  Read More

Get Involved

As the Community for Clean Water, PREP works to unite and encourage you, your friends and family to take simple steps to reduce water pollution caused by our every day actions. The power to make a difference lies in every one of us changing small behaviors so that all of us can continue to enjoy this fantastic place we call home. Read More

Partnerships & Initiatives

PREP is what it is because of strong partnerships and collaborations, the work of protecting and preserving our estuaries could not be successful without the tireless efforts and cooperation from many. A primary initiative of PREP is to conserve natural areas and restore ecosystems that support estuarine health. PREP ‘s guiding document is the Piscataqua Region 2010 Comprehensive Conservation and Management Plan which contains 82 action plans that provide a roadmap to protecting and restoring the Great Bay and Hampton-Seabrook estuaries.  Read More
