Bioaccumulation of trace metals in plant tissues can present a health risk to wildlife, and potentially to humans. The Passamaquoddy Tribe in Maine was concerned about health risks of cadmium (Cd) because of a health advisory for moose liver and kidney consumption due to high Cd levels. In addition to Cd, this study evaluated concentrations of aluminum (Al), calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), nickel (Ni), phosphorus (P), lead (Pb), and zinc (Zn) in four common terrestrial moose-browse species, associated forest soils, and two species of aquatic vegetation on Passamaquoddy tribal land in eastern …

This research project examined the distribution of phytoplankton in the Damariscotta River, as well as environmental factors, such as nutrients, light, and physical conditions, in order to assess the estuary’s ability to sustain additional farms.

Mt. Piscgah Community Conservation Area Management Plan, Winthrop Conservation Commission, Kennebec Land Trust
Maine Town Documents
The 94-acre Mt. Pisgah Community Conservation Area was established in 2003 when the Maine Forest Service granted a conservation easement to the Kennebec Land Trust and then sold the property to the Town of Winthrop. The successful protection of the Mt Pisgah tower property culminated a community-wide effort to conserve the area for outdoor recreation, water quality protection, and continued access to the lookout tower.

The MDI Water Quality Coalition has been working with citizens on water quality related projects in Frenchman Bay since 1997. Over the last decade, many issues of concern to the residents and users of the bay have come up. These issues include polluted runoff from paved streets and parking lots, increasing development in the upper reaches of coastal watersheds as well as right on the shoreline, nutrient enrichment of bays, over harvesting of marine resources, shifting of mussel harvesting techniques to aquaculture, building of piers, increasing visitation by cruise ships, contamination of swim areas, declining eelgrass populations, shoreline erosion, and …
Contrasting Chemical Response To Experimental Acidification Of Five Acid-Sensitive Streams, Heather Vanessa Goss
Contrasting Chemical Response To Experimental Acidification Of Five Acid-Sensitive Streams, Heather Vanessa Goss
Electronic Theses and Dissertations
To evaluate the role of stream water and substrates in response to acidification, we experimentally acidified five first-order streams in 2005: East Bear Brook, Hadlock Brook, and Mud Pond Inlet (Maine, USA); Fernow WS3 (West Virginia, USA); and Lesní Potok (Czech Republic). All have forested catchments and low alkalinity water. We evaluated water samples from a reference site above the point of hydrochloric acid addition and from two or three sites located 16 to 94 m downstream. Just before acid addition we collected streambed sediment samples for sequential extraction of metals. Several sediment-water and aqueous processes contributed to neutralization of …
Radon In Ground Water: A Study Of The Measurement And Release Of Waterborne Radon And Modeling Of Radon Variation In Bedrock Wells, Vincente E. Guiseppe
Radon In Ground Water: A Study Of The Measurement And Release Of Waterborne Radon And Modeling Of Radon Variation In Bedrock Wells, Vincente E. Guiseppe
Electronic Theses and Dissertations
Naturally occurring radon gas (222Rn) exists in ground water and drinking water supplies. Research involving radon in ground water requires the ability to accurately measure radon in water. In the absence of a national program, an intercomparison study of laboratories was sanctioned by the State of Maine. The University of Maine research laboratory supplied each laboratory with water samples of various radon concentrations, served as the reference laboratory, and analyzed the results presented here. The external review of the University of Maine laboratory and agreement with some of the participating laboratories verifies its accuracy in measuring radon in water. A …
Public Access To Privately Owned Land In Maine, James M. Acheson
Public Access To Privately Owned Land In Maine, James M. Acheson
Maine Policy Review
In Maine, people have long used private land for recreation. James Acheson points out that this “open land” tradition—unique in the nation—has huge economic implications, especially for the state’s tourism industry. In recent years, there has been a substantial increase in land posting, largely in response to abuses by the public. Although a number of different kinds of institutions have arisen to allow continued public access to private land, Acheson suggests that more needs to be done if Maine’s “open land” tradition is to be maintained
A Geochemical, Isotopic, And Petrologic Study Of A Watershed With Arsenic-Enriched Ground Water In Northport, Maine, Gail Elizabeth Lipfert
A Geochemical, Isotopic, And Petrologic Study Of A Watershed With Arsenic-Enriched Ground Water In Northport, Maine, Gail Elizabeth Lipfert
Electronic Theses and Dissertations
High mean arsenic concentrations up 26.6 ¹mol/L (1990 ¹g/L) occur in ground water within a watershed at Kelly's Cove, Northport, Maine, USA. The Kelly's Cove watershed is a fractured-bedrock system composed of sul¯dic schist with granitic to dioritic intrusions. Arsenic is enriched in these rocks up to 1050 mg kg¡1 (average: 68 mg kg¡1). The distribution of arsenic in the bedrock appears to be controlled by the presence of arsenopyrite and arsenian pyrite, that occur primarily in post-metamorphic, tourmaline + quartz § carbonate veins and the Kelly's Cove granite. Based on the metamorphic signature of the tourmaline chemistry and the …
