(2008) Wellhead Protection Program - Lary Lane, Gilman, And Stadium Wells In The Town Of Exeter, Nh, Wellhead Protection Program

PREP Reports & Publications

A Wellhead Protection Program (WHPP) identifies existing and potential sources of contamination to public water supply wells. The purpose of a WHPP is to prevent contamination of groundwater used for drinking water, recognizing the best way to maintain high quality drinking water is to prevent contaminants from reach drinking water sources. The Federal Safe Drinking Water Act requires states to develop Wellhead Protection Programs. New Hampshire’s Groundwater Protection Act, NH RSA 485-C, provides the basis for protection in New Hampshire. The Town of Exeter, New Hampshire has developed this WHPP for three wells, the Lary Lane well, the Gilman well, …

Testing Of Great Bay Oysters For Two Protozoan Pathogens, John I. Nelson

Eelgrass Distribution In The Great Bay Estuary 2005, Frederick T. Short

PREP Reports & Publications

Eelgrass (Zostera marina) is an essential habitat for the Great Bay Estuary (GBE) because it provides food for wintering waterfowl and habitat for juvenile fish and shellfish. Eelgrass is the basis of an estuarine food chain that supports many of the recreationally, commercially and ecologically important species in the estuary. Additionally, eelgrass filters estuarine waters, removing both nutrients and suspended sediments from the water column. Eelgrass in the Great Bay Estuary is the largest monoculture in the State of New Hampshire and is considered a vital resource to the State’s marine environment. The present report describes and interprets the eelgrass …

Newmarket Open Space Conservation Plan, Ellen Snyder

PREP Reports & Publications

Open spaces – forests, fields, wetlands, floodplains, salt marshes, rivers and streams – are integral to our community. These lands and waters that thread through our neighborhoods are a scenic reminder of our history, when people made their living by working the land. Yet we still depend on these open spaces for our health and our wellbeing. These places provide many “services” such as clean air, flood control, filtering pollutants and purifying drinking water, natural pest control, plant pollination, cooler summer temperatures, and areas for relaxing, exercising and recreating. Collectively these can be thought of as a “natural services network” …

Impacts Of Wastewater Treatment Facilities On Receiving Water Quality, Stephen H. Jones

PREP Reports & Publications

The Squamscott River has had extended episodes of low dissolved oxygen (DO) that have been recorded at a site near its mouth over the past few years. These episodes were recorded as a result of temporally intensive monitoring by a datasonde, whereas data for the rest of the river has been spotty. Thus, the spatial extent of low DO episodes is not known. This study was designed to better characterize the spatial extent of DO conditions along the full length of the river, as well as to determine nutrient and other water quality parameters along the transect to help understand …

2006 Great Bay Organic Nitrogen (Pon & Don) And Light Extinction (Par) Monitoring Program, Jonathan Pennock

PREP Reports & Publications

Nitrogen is most often considered to be the limiting nutrient for plant growth in marine waters. As a result, knowledge of nitrogen loading and ambient water-column concentrations are considered to be critical to understanding the response of aquatic ecosystems to nutrient over-enrichment—a process known as eutrophication when it results in the excess production of organic matter.

Plant production in many estuarine systems may also be limited by light availability as a result of high levels of turbidity in the water resulting from sediments, dissolved organic matter, and phytoplankton in the water column. Light limitation resulting from human-induced increases in turbidity …
