Marine environment is the largest habitat covering approximately 70% of the total earth surface. Oceans are the main regulatory agent of earth’s climate and harbour a huge diversity of living organisms. Marine environment provide a unique ecological niche to different microbes which play a significant role in nutrient recycling as well as various environmental activities. However with rapid industrialization, urbanisation, ship trafficking and mining activities enormous amounts of waste including heavy metals, hydrocarbons, chemicals, dyes, organic load, agriculture waste, pesticides, antifoulants (e.g. tributyltin) and bacterial pathogens have accumulated in marine/estuarine environments over several decades and pose a serious threat to marine macro and micro biota and humans and therefore require special attention. However some natural marine microbes are known to possess diverse resistance mechanisms and degradation pathways to variety of toxic pollutants and these unique characteristics of marine/estuarine bacteria proved to be an ideal tool in bioremediation of contaminated marine and estuarine environmental sites. Reclamation of marine polluted environments using marine microbes has been found to be effective, affordable and ecofriendly technological solution over conventional physical and chemical methods. Objective of this book is focus on marine pollution and application of marine microorganisms in cost effective and ecofriendly methods of pollution abatement.

The increasing human population and the associated activities have negatively influenced the ecosystems and life on earth. The continuous addition of agrochemicals, heavy metals and industrial wastes/ effluents in the ecosystems have caused great harm, including loss of productivity, biodiversity, climate change and diseases in plants, animals and humans, resulting in increased marginal lands and endangered sustainability of life on earth. Hence, there is an urgent need to reverse the impact of dangerous pollutants through a holistic, sustainable and biotic approach. Bioremediation involves the utilization of biological systems, mainly plants (phytoremediation) or microorganisms or both in combination (rhizoremediation) for the removal or degradation of pollutants and revive the habitats in an eco-friendly manner. Recently, there have been many success stories related to bioremediation involving plants or plant-microbe interactions. These success stories are related to the removal of heavy metals, pesticides, polyaromatic hydrocarbons, explosives, radionuclides or reduction of biological oxygen demand, total dissolved solids, total suspended solids, oil spills in water bodies. Rhizoremediation has also been successfully used for reclamation of saline or marginal soils. With the range of pollutants and the total area (on earth) covered by these toxic chemicals, it is important that these eco-friendly technologies be utilized in a better way. The book throws light on the recent happenings, research and success stories related to bioremediation of polluted habitats through phytoremediation or rhizoremediation. The book also highlights some of the significantly important plant and microbial species involved in remediation, the physiology, biochemistry and the mechanisms of remediation by various plants and microbes, and suggestions for future improvement of bioremediation technology.

From water quality criteria and regulations to advanced techniques and implementation issues, this book offers scientists a toolkit for developing safe and successful reuse strategies. With a focus on specific contaminant removal techniques, this book comprehensively covers the full range of potential inorganic/organic contaminating compounds and highlights proven remediation methods. Socioeconomic implications related to current and future water shortages are also addressed, underscoring the many positive benefits of sustainable water resource management. Offers pragmatic solutions to global water shortages Provides an overview of the latest analytical techniques for water monitoring Reviews current remediation efforts Covers innovative technologies for green, gray, brown and black water reclamation and reuse

This report addresses the microbiological detoxification of hazardous organic compounds before and after they have contaminated soil, groundwater, and other areas. The in situ degradation of toxic organic compounds is often the most cost-effective cleanup approach. Companies which use or provide microorganisms and other products and services for hazardous organic waste detoxification are listed in the appendices of this report. Keywords: Hazardous materials; Water pollution; Pollution control and Abatement; Biodegradation; Detoxification; Degradation; Hazardous wastes; Organic wastes; Microorganisms; Bacteria. (kt).

A small but growing number of municipalities are augmenting their drinking water supplies with highly treated wastewater. But some professionals in the field argue that only the purest sources should be used for drinking water. Is potable reuse a viable application of reclaimed water? How can individual communities effectively evaluate potable reuse programs? How certain must "certain" be when it comes to drinking water safety? Issues in Potable Reuse provides the best available answers to these questions. Useful to scientists yet accessible to concerned lay readers, this book defines important terms in the debate and provides data, analysis, and examples of the experience of municipalities from San Diego to Tampa. The committee explores in detail the two major types of contaminants: Chemical contaminants. The committee discusses how to assess toxicity, reduce the input of contaminants, evaluate treatment options, manage the byproducts of disinfection and other issues. Microbial contaminants, including newly emerging waterborne pathogens. The book covers methods of detection, health consequences, treatment, and more. Issues in Potable Reuse reviews the results of six health effects studies at operational or proposed reuse projects. The committee discusses the utility of fish versus mammals in toxicology testing and covers issues in quality assurance.

Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.
