Innovative Stormwater Treatment Technologies: Best Management Practices Manual, Jillian E. Jones, G. Dana Bisbee, Harry T. Stewart

PREP Reports & Publications

Urban stormwater carries a number of pathogens, nutrients, heavy metals, sediment, and other contaminants as surface runoff flows over land. The increase in impervious or paved surfaces associated with development in urban areas reduces the natural infiltration of precipitation into the ground. With impervious cover, precipitation collects and carries contaminants before draining into nearby surface waters. Stormwater runoff from paved surfaces in developed areas can degrade downstream waters with both contaminants and increased volumes of water. This publication aims to make information on innovative stormwater treatment technologies more available to New Hampshire’s urban planners, developers, and communities. Traditional runoff management …

In this report the phrase 'Bull Toad’s Pond' is intended to include the pond and the shallow water wetland system that surrounds the pond. The original scope of this project was directed at a detailed analysis and review of existing available data, field determinations, and an analysis of the current conditions of Bull Toad’s Pond. In addition, the purpose of this project was to offer recommendations of alternative solutions for restoring the functions and values of this degraded …

Lamprey And Oyster River Watersheds River Stewardship Program, Margaret Watkins

PREP Reports & Publications

This project was designed for riverfront landowners and local land use decisionmakers to fill a critical gap in shoreland protection: land management by individual riparian landowners. By working directly with individuals in a hands-on venue, we intended to build a more informed public, knowledgeable about the value of riparian buffers. A better appreciation of the value of buffers not only improves stewardship of individual properties, but also is likely to inspire stronger support for regulatory approaches to shoreland protection. The project addressed several NHEP goals. The approach was to hold a series of public workshops, lead by specialists in water …

Nhep Management Plan 2000, New Hampshire Estuaries Project

PREP Reports & Publications

This Comprehensive Conservation and Management Plan of the New Hampshire Estuaries Project presents a broad framework and specific list of actions to protect and enhance the environmental quality of the estuaries of the State of New Hampshire. It is intended to be a guide for all who use, enjoy, or care about the state’s estuarine resources. The NHEP Management Plan addresses the environmental quality of the entire watershed draining to New Hampshire coastal waters, but focuses action efforts on the lands surrounding the Great Bay and Hampton-Seabrook Estuaries. Due to the national significance of their natural resources, the New Hampshire …

A Technical Characterization Of Estuarine And Coastal New Hampshire, New Hampshire Estuaries Project, Stephen H. Jones

PREP Reports & Publications

This technical characterization report provides a comprehensive compilation of information on key issues related to water quality and natural resources in the estuaries of New Hampshire. The report has identified some significant issues and problems facing these estuaries that will require management attention. Issues common to estuaries across the nation have been addressed to varying extents, depending on their significance in New Hampshire. Much of the trend information is biased by the sporadic interest given to the different resources and water quality issues through the years. Studies have focused to differing extents on the various areas of the coast, providing …

State Of New Hampshire's Estuaries, New Hampshire Estuaries Project

PREP Reports & Publications

In this State of the Estuaries Report, the New Hampshire Estuaries Project presents a snapshot of the environmental condition of the state’s estuaries. The Report describes the region’s valuable natural resources, and their essential links to the cultural and economic well-being of the Seacoast region and the state. It identifies challenges and problems that threaten the unique character and natural resource wealth of the estuaries.

This State of the Estuaries Report summarizes the Technical Characterization’s detailed assessment of the environmental condition of the estuaries, and describes in lay terms the scientific basis for the water quality, land use, and other …

Bioavailability And Trophic Transfer Of Humic-Bound Copper From Bacteria To Zooplankton, Emile M. Lores, Jonathan Pennock

School of Marine Science and Ocean Engineering

ABSTRACT:

The effect of humic acid (HA) on uptake and transfer of Cu by selected marine organisms from the microbial loop was determined. Bacteria grown with and without 15 µg Cu l^-1 and with and without 10 mg Suwannee River Humic Acid (SRHA) l^-1 were fed to Uronema sp. The Uronema were subsequently fed to Acartia tonsa to determine the effect of humic acid on the uptake and transfer of Cu from bacteria to copepods. The presence of 10 mg SRHA l^-1 reduced Cu uptake in A. tonsa by an average of 54% and significantly reduced the …

Regulation And Management Of New Hampshire Estuaries: A Base Programs Analysis, Nh Department Of Fish And Game, Great Bay National Estuarine Research Reserve

PREP Reports & Publications

This report is designed to provide a snapshot of the local, state and federal management framework for the estuaries of the state. Natural resource management, land use regulation, research, education and funding are all important pieces of this framework, and each is reviewed in relation to specific problems of the estuaries. The report first summarizes the issues and potential issues confronting the estuaries and then reviews the existing policies and programs aimed at dealing with these issues.

Temporal Alternation Between Light- And Nutrient-Limitation Of Phytoplankton Production In A Coastal Plain Estuary., Jonathan Pennock, Jonathan H. Sharp

School of Marine Science and Ocean Engineering

ABSTRACT: The potential for Light- and nutrient-limitation of phytoplankton production was examined in the Delaware Estuary, USA, by combining a hierarchy of expenmental approaches including smallscale bioassay experiments, ecosystem-level analysis of nutrient concentration and stoichiometric ratios, and light-limitation modeling. Light was found to be the predominate regulator of phytoplankton growth throughout the estuary during the winter period as a result of high turbidity and a wellmixed water column. However, during late spring, phosphorus (P) was found to limit growth. This observation was confirmed at each of the experimental levels, and was related to several factors, including elevated input ratios (230:l) …

Comparison Of Predicted And Observed Dioxin Levels In Fish: Implications For Risk Assessment, Judy S. Lakind, Daniel Q. Naiman

RISK: Health, Safety & Environment (1990-2002)

After comparing sampled and modelled dioxin levels in the tissue of fish near pulp and paper mill discharges, the authors argue that, until an improved bioaccumulation model is incorporated into EPA's Risk assessment process, determination of human health Risks associated with consuming dioxin-contaminated fish should be based on sampling.

Variation In A Host-Epiphyte Relationship Along A Wave Exposure Gradient, Phillip S. Levin, Arthur C. Mathieson

New Hampshire Agricultural Experiment Station Publications

The red alga Polysiphonia lanosa (L ) Tandy is an obligate epiphyte that primarily occurs on the fucoid brown algal basiphyte Ascophyllum nodosum (L) Le Jolis In the present study we examine how epiphytic interactions between P lanosa and A nodosum vary along a wave exposure gradient within the southern Gulf of Maine, USA P lanosa was most dense on protected shores, however because the stature of P lanosa was greater on exposed than on sheltered shores, greater biomass occurred In exposed habitats Epiphytlc P lanosa pnmanly attached to inlured vegetative bssue at exposed sites, while ~ t osc currence …

Phytoplankton Production In The Delaware Estuary: Temporal And Spatial Variation., Jonathan Pennock

ABSTRACT:

Phytoplankton production in the Delaware Estuary (USA) was measured over several seasonal cycles (1980-1985). Seasonal variability in daily area1 production (JP; g C m-2 d-l) was dlrectly related to chlorophyll concentrations in the upper estuary, ranging from a maximum of 1.1 g C m-' d-' In summer to a minlmum of d-l) dunng summer in the presence of low phytoplankton biomass (2 to 10 kg Chl I-'), and in mid-estuary [2.6 g C d-l) during the spring diatom bloom (50 to 60 yg Chll-l). Desplte the occurrence of maximum nutnent concentrations in the freshwater region, highest JP and 90 …
