Book Description
The term "emerging contaminants" and its multiple variants has come to refer to unregulated compounds discovered in the environment that are also found to represent a potential threat to human and ecological receptors. Such contaminants create unique and considerable challenges as the push to address them typically outpaces the understanding of their toxicity, their need for regulation, their occurrence, and techniques for treating the environmental media they affect. With these challenges in mind, this handbook serves as a primer regarding the topic of emerging contaminants, with current and practical information to help support the goal of protection where they are encountered. Features Explores the definition, identification, and life cycle of emerging contaminants. Reviews current information on sources, toxicology, regulation, and new tools for characterization and treatment of: 1,4-Dioxane (mature in its emerging contaminant life cycle) Per- and polyfluoroalkyl substances (PFASs; a newer group of emerging contaminant) Hexavalent chromium (former emerging contaminant with evolving science) 1,2,3-Trichloropropane (progressing in its emerging contaminant life cycle) Provides thoughts on opportunities in managing emerging contaminants to help balance uncertainty, compress life cycle, and optimize outcomes.

Book Description
Determination of the distribution of coliform bacteria in the vicinity of the outfall effluent of the Monterey Water Pollution Control Plant was made using the membrane filter technique for enumeration. The coliforms were seen to follow the onshore mass transport of water in the surface layer in response to predominately westerly winds. The extent of penetration of coliforms into the bay north of the outfall is restricted to several hundred yards, while more extensive spreading was observed towards the surf zone. No consistent pattern of variation of the coliform distribution would be related to the tidal cycle. Higher concentrations of coliform bacteria on several occasions seemed to be related to reduced periods of solar radiation. (Author).

Book Description
San Francisco Bay is the largest and most productive estuary on the Pacific Coast of North America. It is also home to the oldest and densest urban settlements in the American West. Focusing on human inhabitation of the Bay since Ohlone times, Down by the Bay reveals the ongoing role of nature in shaping that history. From birds to oyster pirates, from gold miners to farmers, from salt ponds to ports, this is the first history of the San Francisco Bay and Delta as both a human and natural landscape. It offers invaluable context for current discussions over the best management and use of the Bay in the face of sea level rise.
