Emily Alcott, MES, is a fluvial geomorphologist and an ecologist at Inter-Fluve Inc. of Hood River, Oregon. She earned a master of environmental science degree from Yale University and a bachelor of science in biology from Hobart and William Smith Colleges. Her area of expertise is in the management of water resources and the restoration and rehabilitation of cold water stream systems. Her work has primarily been in the Northeast and Pacific Northwest of the United States.
Mark S. Ashton, Ph.D.,
is the Morris K. Jessup Professor of Silviculture and Forest Ecology at the School of Forestry and Environmental Studies at Yale University. He earned his bachelor of science from the University of Maine, College of Forest Resources, and his master of forestry and Ph.D. from Yale University. Professor Ashton conducts research on the biological and physical processes governing the regeneration of natural forests. The results of his research have been applied to the development and testing of silvicultural techniques for restoration of degraded lands and for the management of natural forests for a variety of values. His work is focused on land rehabilitation for watershed management and water quality.

Illuminating opportunities to develop a more integrated approach to municipal water system design, Natural and Engineered Solutions for Drinking Water Supplies: Lessons from the Northeastern United States and Directions for Global Watershed Management explores critical factors in the decision-making processes for municipal water system delivery. The book offers vital insights to help inform management decisions on drinking water supply issues in other global regions in our increasingly energy- and carbon-constrained world.
The study evaluates how six cities in the northeastern United States have made environmental, economic, and social decisions and adopted programs to protect and manage upland forests to produce clean drinking water throughout their long histories. New York, New York; Boston and Worcester, Massachusetts; New Haven and Bridgeport, Connecticut; and Portland, Maine have each managed city watersheds under different state regulations, planning and development incentives, biophysical constraints, social histories, and ownerships.
Some of the overarching questions the book addresses relate to how managers should optimize the investments in their drinking water systems. What is the balance between the use of concrete/steel treatment plants (gray infrastructure) and forested/grassland/wetland areas (green infrastructure) to protect surface water quality? The case studies compare how engineered and/or natural systems are employed to protect water quality.
The conclusions drawn establish that it makes environmental, economic, and social sense to protect and manage upland forests to produce water as a downstream service. Such stewardship is far more preferable than developing land and using engineering, technology, and artificial filtration as a solution to maintaining clean drinking water. Lessons learned from this insightful study provide effective recommendations for managers and policymakers that reflect the scientific realities of how forests and engineering can be best integrated into effective watershed management programs and under what circumstances.
