Book Description
Macroinvertebrates in urban streams in Ohio are potentially compromised by habitat loss, by the annual peak discharge event, and by degraded water quality. The Mill Creek in Southwest Ohio is a significantly channelized river that collects storm water runoff, wastewater treatment plant effluent, permitted dischargers, sanitary sewers, and combined sewers. Channelization areas have had 12-40 years to re-grow. Most of the riparian zone, although narrow, is lined with trees that shade the channel. The result is eutrophication by nutrient loading, some toxic chemical spills, and habitat simplification. This study was designed to show the relative impacts of habitat and water quality on the macroinvertebrate community in a multi-stressed urban stream. Possible limiting factors were quantified and evaluated along the main-stem of the Mill Creek and related to the macroinvertebrates five times over the summer of 2000. The habitat was characterized using the Ohio EPA's QHEI, the estimated peak flow, and pebble counts. Water quality was quantified by the nutrient concentrations found. Both habitat and water parameters were compared to macroinvertebrate density, taxa richness, and the calculated metric, invertebrate community index. Data was collected for base flow in the summer and autumn of 2000-2001. The QHEI and the ICI were linearly related over transects done in four non-consecutive years within a decade. Multiple regression showed several habitat variables correlated to taxa richness. ANOVA identified average species richness was significantly impacted by both water quality and habitat variables. A non-parametric method (detrended canonical correspondence analysis) separated the determinants for invertebrate communities along a nutrient (19.1% of variance) and habitat axis (11.1% of variance).

Book Description
This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. - Provides a concise guide to WQIs: their purpose and generation - Compares existing methods and WQIs and outlines strengths and weaknesses - Makes recommendations on how the indices should be used and under what circumstances they apply
Constructed Wetlands for the Treatment of Landfill Leachates

Book Description
Constructed wetlands are proving to be the best natural treatment system for landfill leachates. Most of the contaminants in landfill leachates are degraded in treatment wetlands. Potential for long-term sustainability and significant cost savings are attractive features of this eco-technology. Documentation of the experience in this use of constructed wetlands has been limited. Constructed Wetlands for the Treatment of Landfill Leachates is the first compilation of the results of research from North America and Europe. Originally presented at an international symposium, this collection of papers offers the most recent research findings from the leading researchers in this new and innovative natural treatment system. Specific issues addressed in the text include: leachate characteristics, and the potential for treatability by constructed wetlands wetland treatment, processes and transformation use of constructed wetlands in cold climatic conditions assessment of the tolerance of wetland plants to the toxicity of leachates role of plants in the treatments of leachates integrated wetland systems performance of different wetland treatment systems cost comparisons of wetland technology vs. traditional treatment technologies The potential for environmental contamination due to leachates from landfills is increasing, and there is an urgent need to find ways and means to treat leachates in a sustainable way Constructed Wetlands for the Treatment of Landfill Leachates will provide an invaluable source of information on the subject for scientists, engineers, practitioners, policy makers, and regulatory officials.
