Evaluation of Effects of Wastewater Treatment Discharge on Estuarine Water Quality

This report marks the completion of a two-year project focused on observed and estimated effects of wastewater treatment facilities (WWTFs) on estuarine water quality within the New Hampshire (NH) Seacoast region. This study was designed and carried out in an effort to help the NH Department of Environmental Services (NHDES) and NH Estuaries Project (NHEP) evaluate the effects of WWTF effluent quality on bacterial and nutrient concentrations in New Hampshire’s estuarine waters, as well as to help NHDES/NHEP identify related WWTF infrastructure problems. An extensive database of bacterial and nutrient concentrations in effluent collected post-disinfection from 9 NH WWTFs and 2 Maine WWTFs that discharge into the Great Bay and Hampton/Seabrook estuaries was developed. The data were used to determine ratios between different bacterial indicators in WWTF effluent, estimates of in-stream bacterial concentrations following effluent discharge to receiving waters and estimates of nutrient loading from selected WWTFs

A study of the crab pot as a fishing gear

The crab pot as a fishing gear was introduced in Maryland waters, following some years of greatly expanded use in Virginia, during the 1939 season, and was widely used during 1940. The 1941 session of the Maryland Legislature, however, illegalized the crab pot. Since that time the device has been given up almost entirely by Maryland fishermen, its attempted use in a commercial way having persisted in diminishing numbers in only one region of the state

Springs of Florida

bulletin which documented the major and important springs in the state (Ferguson et al., 1947). This publication was revised in 1977, with many previously undocumented springs and many new water-quality analyses being added (Rosenau et al., 1977). The Florida Geological Survey's report on first magnitude springs (Scott et al., 2002) was the initial step in once again updating and revising the Springs of Florida bulletin. The new bulletin includes the spring descriptions and water-quality analyses from Scott et al. (2002). Nearly 300 springs were described in 1977. As of 2004, more than 700 springs have been recognized in the state and more are reported each year. To date, 33 first magnitude springs (with a flow greater than 100 cubic feet per second or approximately 64.6 million gallons of water per day) have been recognized in Florida, more than any other state or country (Rosenau et al., 1977). Our springs are a unique and invaluable natural resource. A comprehensive understanding of the spring systems will provide the basis for their protection and wise use.

Spot sampling of nutrient concentrations in the Puarenga catchment, Rotorua

The Centre for Biodiversity and Ecology Research was approached by Tūhourangi Tribal Authority for assistance with measuring water quality in streams in the Puarenga Stream catchment. Water sampling was subsequently undertaken on 18 July 2011 and samples were analysed to determine concentrations of total and dissolved fractions of nitrogen and phosphorus. Nitrogen and phosphorus are both essential plant nutrients which, when present in excess, can cause eutrophication and associated water quality decline of freshwaters. High concentrations of dissolved forms of nitrogen can also be toxic to aquatic organisms. Excessive nitrogen and phosphorus concentrations are typically the result of pollution due to human activities, although groundwater in the Central Volcanic Plateau region can have elevated concentrations of phosphorus arising from natural geological sources. This report summarises the methods used, presents the results and places measured concentrations in context by drawing comparisons with both guideline and regional mean values

Preparations for the Forbes Expedition, 1758, in Adams County, with Particular Focus on the Reverend Thomas Barton

In the year 1755, two events occurred which left their impress upon the history of what was to become Adams county. One was momentous, and its consequences, like concentric ripples produced by a stone hurled into a large body of water, continued to move and shape the history of Pennsylvania\u27s frontier long afterwards. By comparison, the other was insignificant, the mere, almost undetectable slipping of a pebble into the rushing torrent of Time. Yet this second happening eventuated in ways that profoundly contributed to our understanding of Adams county\u27s, and Pennsylvania\u27s, history during the years 1755-59. The lesser of these occurrences had its genesis in the religious needs of a people often neglected in accounts of colonial Pennsylvania, the Anglicans (or members of the Church of England) who dwelt along the western frontier and who, as it fell out, were largely Anglo-Irish and Scots-Irish in origin. Numerically fewer than their Presbyterian neighbors clustered to the north in Cumberland county and to the south in the settlements of Marsh Creek, the people of the Church of England had informally staked out an area for themselves along the Conewago and the Bermudian Creeks in Huntington, Tyrone and Reading townships in what was then western York county. A shoal precariously situated in a sea of Presbyterians, Seceders, and Covenanters, and cut off from the nearest Anglican church, St. James\u27s in Lancaster, by the triple geographic barriers of dense forest, broad river, and vast distance, they felt the survival of their religion an uncertain thing indeed.

Great Bay Coast Watch: A Citizen Water Monitoring Program Volunteer Water Quality Monitoring Manual, 2004

The Great Bay Coast Watch is citizen volunteers, working within the UNH Cooperative Extension/NH Sea Grant Program, protecting the long-term health and natural resources of New Hampshire’s coastal waters and estuarine systems through monitoring and education projects. The purpose of this document is to present step-by-step instructions for conducting water quality testing in support of the Great Bay Coast Watch (GBCW)

Results of 2013 Macroalgal Monitoring and Recommendations for Future Monitoring in Great Bay Estuary, New Hampshire

The recently designated nitrogen impairment and reports of elevated macroalgal growth in Great Bay Estuary indicate ecological imbalance. However, reversing the Estuary’s ecological decline will require commitment of considerable resources and is complicated by the variety of sources that deliver nitrogen to the Estuary and the intermittent nature of historic macroalgal monitoring. To advance our understanding of the macroalgal and nitrogen dynamics of the Estuary, data were collected via three approaches: 1) assessing plant cover and biomass along transects; 2) assessing plant cover at randomly selected points; and 3) comparing the nitrogen isotope ratios of macroalgae collected from different habitats. The results offer insight into changes in macroalgal abundance and species composition and the relative importance of various nitrogen sources to macroalgae in Great Bay. Overall, our results corroborate the findings of increasing macroalgal blooms in previous studies and suggests plausible directions for a long-term macroalgal monitoring program
