Project Scope
|
A committee, formed by the Water Science and Technology Board will assess
geological, geochemical, biological, engineering, and institutional factors
that may affect the performance of sustainable underground storage technology,
based in part on a review and evaluation of existing projects. It will also
provide an overview of some of the research needs and priorities required for
the implementation of such projects.
Specifically, the study will assess and make recommendations with
respect to the following questions:
* What research needs to be done to develop predictors of performance for
underground storage projects based on hydrogeology (degree of aquifer
confinement and homogeneity, regional hydraulic gradient, etc.), geochemistry
of the source water and the aquifer, well characteristics, and the character of
the recharge water in terms of contaminants, disinfectants, and microbes?
* What are the long-term impacts of underground storage (e.g., hydraulic,
geotechnical, geochemical, adsorptive capacity of contaminants, etc.) on
aquifer utility at wellhead and regional scales, and can these impacts be
ameliorated?
* What physical, chemical, and geological factors associated with underground
storage of water may increase or decrease human and environmental health risks
caused by microbes, inorganic contaminants such as nitrite, disinfectant
by-products, endocrine disruptors, personal care products, pharmaceuticals, and
other trace organic compounds?
* Are there any chemical markers or surrogates that can be used to help assure
regulators and the public of the safety of water for groundwater recharge? What
should we monitor and at what spatial and temporal scales?
* What are the challenges and potential for incorporating sustainable
underground storage projects into current systems approaches to water
management for solving public and environmental water needs?
Sponsors: American Water Works Association Research Foundation, WateReuse
Foundation, U.S.Geological Survey, The CALFED Bay-Delta Program and the
California Department of Water Resources Conjunctive Water Management Branch
(both under the Association of Bay Area Governments/San Francisco Estuary
Project), City of Phoenix, Inland Empire Utilities Agency, Sanitation Districts
of Los Angeles, Chino Basin Watermaster, and NRC Internal funding from the
President's Committee of the National Academies
The approximate starting date for the project is 01/01/2005.
A final report will be issued at the end of the project in approximately 24
months.
ADDENDUM: The project duration has been extended. A final report is expected on 9/30/2007
