MEASUREMENT ON THE EFFECTS OF EROSION CONTROL ON AQUATIC LIFE IN THE NEMADJI RIVER AND ITS TRIBUTARIES
(1977)The influence of sedimentation and turbidity associated with erosion from the Nemadji River Basin is assumed to have deleterious effects on the aquatic biota. Studies in the past year have concentrated on identifying fish ... -
FRESHWATER AQUATIC CRITERIA DEVELOPMENT AND TOXICITY TESTING
(1986)Aquatic toxicity testing was completed on a number of compounds/elements to supply the necessary data for preparation of Criteria Documents in 1986. The compounds/elements tested included hexachlorobenzene, selenium IV & ... -
PRELIMINARY INVESTIGATION OF THE ROLE OF AQUATIC MACROPHYTES IN HEAVY METAL UPTAKE FROM WATER WITH COAL PARTICLES
(1981)A survey was made and representative samples of vascular macrophytes from the Superior, Wisconsin-Duluth, Minnesota Harbor were collected in August 1975 and stored in a frozen condition until processed. The processed samples ... -
Static Coal Storage - Biological Effects on the Aquatic Environment
(1977)Benthic samples taken from four regions of the ORBA Coal dock facility indicated that the aquatic environment was moderately polluted as indicated by the kinds of benthic species present and by the diversity index value. ... -
THE EFFECTS OF RED CLAY TURBIDITY AND SEDIMENTATION ON AQUATIC LIFE IN THE NEMADJI RIVER SYSTEM
(1978-10-03)Red clay erosion in southwestern Lake Superior has been a natural process along shorelines and in tributary streams and rivers since decline of lake levels following the Pleistocene period. Exposure of the unconsolidated ... -
FISHERY ASSESSMENT FOR THE DOUGLAS COUNTY SUBMERGED LANDS BETWEEN ORBA AND WISCONSIN GRASSY POINT
(1977-09-30)A fishery assessment was _conducted of the embayment between the present ORBA Coal Facility and Wisconsin Grassy Point in the St. Louis Bay. These are Douglas County submerged lands (platted government lots) which are being ... -
LAKE SUPERIOR SHORELINE VEGETATION AND EROSION: AN ECOLOGICAL SURVEY
(1980-04-15)Shoreline erosion along the Great Lakes continues to be a major economic and environmental concern. Of the nearly 5900 km. of shore- line, approximately 60% is erodible glacial clays, sands, or gravels. Fifty percent of ... -
CHEMICAL AND PHYSICAL ANALYSES OF SELECTED HIGHWAY CONSTRUCTION MATERIALS IN DOUGLAS COUNTY, WISCONSIN
(1976-10)A proposal to use sediments dredged from the Superior=Duluth Harbor as construction material for the proposed Arrowhead High Bridge has been the impetus be hind this study. The focus of the study is a comparison of ... -
BIOACCUMLATION STUDY PCDDs and PCDFs Residues in Fish Tissue A Progress Report
(1987-03-06)The bioaccumulation study is an outgrowth of the EPA's National Dioxin Study concerned with assessing contamination from 2,3,7,8-tetrachloro-p- dioxin (2,3,7,8-TCDD) in soil, water, sediment, and fish tissue. Phase 2 of ... -

TEST EXPLORING THE EFFECTIVENESS OF THE ULTRASONICATOR INVASIVE SPECIES WATER TREATMNET FOR BALLAST WATER MANAGEMNET
(2022-06-06)This technical report presents findings from bench-scale evaluation of the ultrasonicator invasive species water treatment developed by UPIR LLC to inactivate aquatic organisms. This evaluation was the first attempt to ... -
COMPARISON OF COPPER, LEAD AND ZINC TOXICITY TO FOUR ANIMAL SPECIES IN LABORATORY AND ST. LOUIS RIVER WATER
(1983)A study was conducted to compare the toxicities of copper, lead and zinc in laboratory water with their respective toxicities in water from the St. Louis River. St. Louis River water was collected upstream of major ... -
TRANSPORT OF TOXIC SUBSTANCES INTO LAKE SUPERIOR BY SUSPENDED SOLIDS
(1983-10)A primary threat to Great Lakes sport and commercial fisheries arises from contamination problems due to the introduction of certain xenobiotic chemicals in aquatic environments. Of particular concern are hydrophobic ... -
