Metal Mining

Some useful information on metal mining in the Tucson area can be found in Southwest Groundwater Consultants, Inc., Conservation and CAP Use Potential of Tucson AMA Mines, Prepared for Arizona Department of Water Resources, TAMA, 1997. Pima Association of Governments, Groundwater Monitoring in the Tucson Copper Mining District - Detailed Upper Santa Cruz Basin Mines Task Force Area Recommendations, July 1983. Arizona Department of Mines and Mineral Resources, Arizona's Mining Update, 1998.

Chapter 6: ENSURING SAFE DRINKING WATER

Information about water quality in Arizona is available from the EPA Web site. ADEQ also has a Web site with Arizona information. ADEQ's biennial reports (published in even-numbered years) on water quality in Arizona contain valuable information about surface and groundwater quality, including contamination sites of special concern. See Arizona Department of Environmental Quality. Arizona Water Quality Assessment 1996. The USGS is collecting a large amount of water quality information under its NAWQA Project (National Water Quality Assessment) some of which is available from the Tucson office. Pima County, City of Tucson, Dames and Moore. A summary of the TCE cleanup project is in TARP In-Channel Recharge Pilot Proposal, Abbreviated Report (Pima County, City of Tucson and Dames and Moore. January 1997).

Water Quality

Some general introductions to water quality issues can be found in several issues of the WRRC Arroyo by Joe Gelt. These include"Water Quality, a Complex Issue" (Summer 1987), "Nonpoint Source Pollution: Unfinished Business on the Water Quality Agenda" (April 1990), "Constructed Wetlands: Using Human Ingenuity, Natural Processes to Treat Water, Build Habitat," (March, 1997) and "Microbes Increasingly Viewed as Water Quality Threat" (March, 1998).

The Pima Association of Governments has published a series of reports on regional water quality matters. Topics include A Regional Plan for Water, Sewerage and Solid Waste Management; An Assessment of Groundwater Quality Near the Sahuarita Landfills, Sahuarita, Arizona; Phase I Report. Final, Avra Valley Recharge Project Stable Isotope Study Year-End Progress Report Fiscal Year 1996-1997; CAP Water Salinity Impacts on Water Resources of the Tucson Basin; Central Avra Valley Storage and Recovery Project Pilot Phase and Expanded Pilot Phase Stable Isotope Study; Fiscal Year 1997-1998 Progress Report; Groundwater Monitoring in the Tucson Copper Mining District - Detailed Upper Santa Cruz Basin Mines Task Force Area Recommendations; Landfills Along the Santa Cruz River in Tucson and Avra Valley; Arizona and the Water Quality State of the Region Report.

Public attitudes toward CAP water were surveyed by Gary Woodard and other in Impacts of Changes in Water Quality and Consumer Responses in Tucson, Arizona. (WRRC 1993). Malcolm Pirnie Environmental Engineers looked at another similar community's experience with a change in water source in Investigation of Potable Water Complaints in Dickinson, Texas (Malcolm Pirnie, Inc., Special Study Report, May, 1986).

Water Treatment

Dames and Moore produced a series of papers for Tucson Water on CAP Use Study for Quality Water in 1994 and 1995.

Corrosivity

A study was done for Tucson Water by M. McGuire and others, Review of Corrosion-Related Water Quality Problems in the City of Tucson (McGuire Environmental Consultants 30 September, 1993).

More general discussions of corrosivity are by R. Lane, Control of Scale and Corrosion in Building Water Systems (McGraw Hill, New York, 1993) and I. Wagner, Internal Corrosion in Domestic Drinking-Water Installations. Aqua, 41(4), 219-223, 1992. The effects of corrosion on steel were studied by R.J. Pisigan and J. Singley, Effects of Water Quality Parameters on the Corrosion of Galvanized Steel (Journal American Water Works Association, 76-82, November, 1985).

Disinfection and Disinfection Byproducts

These are just a few of many studies of disinfection treatment methods and disinfection byproducts. White, G., The Handbook of Chlorination, Van Nostrand Reinhold Company, New York; McGuire, M., S. Reiber, R. Sierka, J. Singley, and C. Steelink, Disinfectants for Drinking Water Treatment- A White Paper (Prepared for Tucson Water by Central Arizona Project Water Quality Expert Panel), 25 April, 1995.

Disinfection byproducts are discussed in R.J. Bull's Toxicology of Drinking Water Disinfection, (Washington State University, Pullman, WA); G. Cline and J. Russell's An Evaluation of Treatment Strategies for the Control of Disinfection By-Products: Water Quality vs. Cost and W.H. Glaze's Reaction Products of Ozone: A Review. Environmental Health Perspectives, 69, 151-157, 1986. A great deal of information on this subject is available from the EPA Web site.

Salinity

Studies of salinity in the Colorado River include the Colorado River Basin Salinity Control Forum's Water Quality Standards for Salinity, Colorado River System, 1993; the U.S. Department of the Interior's Quality of Water - Colorado River Basin (Progress Report No. 18, 1997); and T.G. Miller and others The Salty Colorado, The Conservation Foundation, Washington D.C., 1986.
