An Introduction to Water Quality and Water Pollution Control

Kenneth M. Vigil

Oregon State University Press, 2003

Clean Water is a book for anyone concerned about this precious resource who wants to become better informed. In straightforward language, Kenneth Vigil provides a comprehensive introduction to the many scientific, regulatory, cultural, and geographic issues associated with water quality and water pollution control.

Most other books on water quality and pollution control are highly technical and very specific, and are aimed at engineers, scientists, or attorneys. Clean Water, on the other hand, is a comprehensive discussion of the subject intended for a wider audience of science students, educators, and the general public.

Vigil avoids the use of technical jargon and uses many photos and diagrams to illustrate and explain concepts. He provides sufficient detail to educate readers about many broad topics and includes additional references at the end of each chapter for exploring specific topics in more detail.

Clean Water summarizes the basic fundamentals of water chemistry and microbiology and outlines important water quality rules and regulations, all in concise, understandable prose. It describes the basic scientific principles behind water pollution control and the broader approach of addressing water pollution problems through watershed management. There are sections on drinking water and on citizen involvement in water pollution control efforts at home and in the community.

Impurity and Purification in Early Judaism and the Jesus Tradition

Thomas Kazen

SBL Press, 2021

This collection of essays by Thomas Kazen focuses on issues of purity and purification in early Judaism and the Jesus tradition. During the late Second Temple period, Jewish purity practices became more prominent than before and underwent substantial developments. These essays advance the ongoing conversation and debate about a number of key issues in the field, such as the relationship between ritual and morality, the role and function of metaphor, and the use of evolutionary and embodied perspectives. Kazen's research stands in constant dialogue with the major currents and main figures in purity research, including both historical (origin, development, practice) and cognitive (evolutionary, emotional, conceptual) approaches.
