A thorough analysis of public policy and the Clean Water Act'seffect on water quality in the U.S. Using water quality data and historical records from the past 60years, this book presents the measured impact of the 1972 CleanWater Act on domestic waterways-ecologically, politically, andeconomically. Municipal Wastewater Treatment supports thehypothesis that the Act's regulation of wastewater treatmentprocesses at publicly owned treatment works (POTW) and industrialfacilities has achieved significant success. The authors' case ispresented in: * Background information on the history of water pollution controland water quality management * Chapters addressing long-term trends in biochemical oxygen demandloadings from municipal wastewater plants and the "worst-case"dissolved oxygen levels in waterways downstream of point sourcesbefore and after the Clean Water Act * Nine case study assessments of long-term trends of pollutantloading water quality and environmental resources associated withPOTW discharges Using long-term trends in dissolved oxygen as the key indicator ofwater quality improvements, this book provides a detailedretrospective analysis of the effectiveness of the water pollutioncontrol policies and regulations of the 1972 Clean Water Act. Thesuccesses of the Act that have been achieved over the past 30 yearsare placed in the historical context of the "Great SanitaryAwakening" of the 19th century and changes in public policies forwater supply and water pollution control that have evolved duringthe 20th century to protect public health and the intrinsic valueof aquatic resources.

A tragedy of Virginian colonial frontier In the summer of 1786 a large war party of Shawnee Indians entered Abb's Valley, Virginia, and descended on the household of militia officer Captain John Moore which included members of his immediate family together with hired labourers. The family occupied a substantial log building and were well armed, so Moore believed that his family was well placed to fight off a small Indian attack. The nearest homestead was six miles away and Moore, relying on his own abilities, thought it unnecessary to follow the example of neighbours by taking refuge in the nearest fort. The attack achieved complete surprise and Moore was killed before he could reach the safety of the house. What followed was an appalling, but typical, Indian massacre of the colonial period frontier in the 18th century. Various family members, young and old, were slaughtered on the spot, the property was set alight and a substantial herd of livestock was taken. Surviving members of the Moore family were taken as captives to the Indian townships, several of them being murdered on the journey. Once the survivors reached the Indian village there followed another period of torture which for Mrs. Moore and a teenage daughter proved fatal. Two young women survived their ordeals to eventually be ransomed. The story of this notable frontier tragedy was written by James Moore, a son of Mary Moore, who was one of the two ransomed captives. This a vital account of the struggles endured by the early settlers of the American wilderness and will be of essential interest to anyone interested in the early history of the state of Virginia.
