Evaluation of Water Quality Projects in the Lake Tahoe Basin

Lake Tahoe is a large sub alpine lake located in the Sierra Nevada Range in the states of California and Nevada. The Lake Tahoe watershed is relatively small (800 km(20) and is made up of soils with a very low nutrient content and when combined with the Lake's enormous volume (156 km(3)) produces water of unparalleled clarity. However, urbanization around the Lake during the past 50 yr has greatly increased nutrient flux into the Lake resulting in increased algae production and rapidly declining water clarity. Lake transition from nitrogen limiting to phosphorous limiting during the last 30 yr suggests the onset of cultural eutrophication of Lake Tahoe. Protecting Lake Tahoe's water quality has become a major public concern and much time, effort, and money has been, and will be, spent on this undertaking. The effectiveness of remedial actions is the subject of some debate. Local regulatory agencies have mandated implementation of best management practices (BMPs) to mitigate the effects of development, sometimes at great additional expense for developers and homeowners who question their effectiveness. Conclusive studies on the BMP effectiveness are also expensive and can be difficult to accomplish such that very few such studies have been completed. However, several project evaluations have been completed and more are underway. Such study usually demonstrates support of the project's effectiveness in decreasing nutrient flux to Lake Tahoe. Here, we review the existing state of knowledge of nutrient loading to the Lake and to highlight the need for further evaluative investigations of BMPs in order to improve their performance in present and future regulatory actions.

Assessment of pollution profile in Buyukcekmece Watershed, Turkey

Buyukcekmece Lake located north of the Marmara Sea coast of Turkey is the third largest water resources among the six main reservoirs of a megacity Istanbul, providing 17% water demand. This study aims to investigate the water quality changes in Buyukcekmece Lake and to classify it in accordance to Turkish Water Pollution Control Regulation for inland surface waters, and assess the impacts of the land-use practices, population density, and settlement in the Buyukcekmece watershed. Physical, chemical, and biological quality of Büyükçekmece Lake has been investigated between December 2007 and June 2008 by collecting samples from the Lake and four streams that feed Büyükçekmece Lake. Land use profile maps of the water basin were created by using ARC-GIS to ensure the quality of drinking water. It was determined that the water quality of Büyükçekmece Lake was still of overall second class, implying that it can be used as a safe drinking water resource following a conventional water treatment scheme; however, it is moving toward the third class. Remarkable portion of the pollution in water basin was attributed to domestic wastewater discharges. Agricultural areas that occupy more than half of the water basin have also adversely affected the water quality.     

Spatial distribution and multiple sources of heavy metals in the water of Chaohu Lake,Anhui, China

In this study, a survey for the spatial distribution of heavy metals in Chaohu Lake of China was conducted. Sixty-two surface water samples were collected from entire lake including three of its main river entrances. This is the first systematic report concerning the content, distribution, and origin of heavy metals (Cu, Cr, Cd, Hg, Zn, and Ni) in the Chaohu Lake water. The results showed that heavy metals (Cu, Cr, Zn, and Ni) concentrations in the estuary of Nanfei River were relatively higher than those in the other areas, while content of Hg is higher in the southeast lake than northwest lake. Moreover, Cd has locally concentration in the surface water from the entire Chaohu Lake. The heavy metal average concentrations, except Hg, were lower than the cutoff values for the first-grade water quality (China Environment Quality Standard) which was set as the highest standard to protect the social nature reserves. The Hg content is between the grades three and four water quality, and other heavy metals contents are higher than background values. The aquatic environment of Chaohu Lake has apparently been contaminated. Both the cluster analysis (CA) and correlation analysis provide information about the origin of heavy metals in the Lake. Our findings indicated that agricultural activities and adjacent plants chimneys may contribute the most to Cd and Hg contamination of Chaohu Lake, respectively.     

基于湖北省12个中小型湖泊的水环境遥感监测应用示范

以《湖北省水环境遥感监测示范系统》为数据处理平台,对2012—2014年湖北省大东湖水网、梁子湖水系和汤逊湖水系共计12个湖泊的水质类别以及营养状态级别进行遥感监测,并对比实测数据进行精度评价。结果表明:遥感监测的梁子湖、豹澥湖和严西湖水质相对较好,杨春湖、北湖和南湖水质相对较差且富营养化状况较为严重。该系统能很好地实现对水质优良达标湖泊以及富营养化湖泊的识别。对示范区域各湖泊水质类别和营养状态级别的遥感监测,基本上能满足业务化运行的需求。个别湖泊遥感监测精度较低,主要表现为遥感监测的湖泊水质类别和营养状态级别均要优于实测的结果。系统对于面积相对较大的湖泊遥感监测精度更高。     

生态补水对玄武湖水质的影响

分析南京玄武湖1997年-2010年的水质变化,以及生态补水与玄武湖水质变化的关系。结果表明,玄武湖于1998年实施生态补水,随着生态补水的持续运行和生态补水量的不断增加,玄武湖水质得以显著改善,其水质类别由生态补水前的劣V类水体转为V类水体,并接近于Ⅳ类水体,富营养化程度由重度富营养化水平转为轻度富营养化水平。目前玄武湖主要营养物质来源于生态补水,相关性分析显示各湖区TN浓度与生态补水中TN浓度呈显著相关关系。
