This book was released on 1983 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations on the effectiveness, persistence and drift of 2,4-D(Aqua-Kleen) were reviewed following 33 treatments to controlEurasian water milfoil between 1976 and 1981. These experimentsindicated that in certain locations, 2,4-D was effective inremoving nuisance weed growth for up to three years followingtreatments. Legal considerations, procedures for application andmonitoring, and technical information on 2,4-D and othertreatment methods were reviewed to guide implementation of futuretreatment programs. The major advantage of herbicide use wasthat in some sites it could be applied relatively quickly, overlarge areas, at a low cost. The major limitation of herbicidetreatments was possible conflicts with water use. Followingexperimental treatments, concentrations of 2,4-D above thedrinking water standard (0.1 mg/L) persisted in the treated areafor a maximum of 4 to 6 days. Drift at this concentration wasdetected at a maximum of 125 m from open water treatments of 12ha or less in large lakes. Low concentration of herbicide (justabove 0.001 mg/L) were observed to drift up to 2 km and, typically, persisted for less than 40 days in treatment areas. It was unlikely that well water near treatment areas could becontaminated with 2,4-D, but the potential for hydrauliccontinuity between wells and treated water should be considered. No significant detrimental effects on non-target organisms wereobserved, although agencies responsible for wildlife resourcesshould be contacted about new treatment sites.

Download or read book Lake and Reservoir Restoration written by G. Dennis Cooke and published by Elsevier. This book was released on 2013-10-22 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.
