WELL STATIONS There are five deep well stations that receive water from the aquifer. The depths of each well casings range from 250 to 460 feet. PUMPS The pump stations located throughout the city pump water to the tanks and provide adequate pressure to the water system. STORAGE The city utilizes three elevated storage tanks with a combined capacity of 1.6 million -gallons located near the Portneuf Wellness Complex. Recently the city completed a 1.5 million -gallon underground storage tank located on Trueman Street, south of Siphon Road.

We are pleased to present this year's Annual Water Quality Report (Consumer Confidence Report) as required by the Safe Drinking Water Act (SDWA). This report is designed to provide details about where your water comes from, what it contains, and how it compares to standards set by regulatory agencies. This report is a snapshot of last year's water quality. We are committed to providing you with information because informed customers are our best allies. -Do I need to take special precautions? Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno -compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/ AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Water Drinking Hotline (800-426-4791). -Additional Information for Nitrate Nitrate in drinking water at levels above 10 ppm -Why are there contaminants in my drinking water? Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline (800-426-4791). -Additional Information for Lead If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. City of Chubbuck is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at http://www.epa.gov/vour-drinking-water/safe-drinking-water-hotline is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider. Source water assessment and its availability The state has completed an assessment of our source water. That report is available for review at the City Offices. -How can I get involved? The City has attempted to make this report informative and readable. This report shows our water quality and what it means. If you have questions about the report or your drinking water, please call the City Public Works offices at (208) 237-2430, and further assistance will be provided. If you would like to have input on how your drinking water is provided, you may either call the number above, or attend the City Council meetings. 1� WATER QUALITY REP017 ANNUAL 2Uz For more information about this report or if you have ql relating to your drinking water, please visit our web https:/ /cityofchubbuck.us/water-waste-water/ or contact us at: The City of Chubbuck Water Department 175 Park Lawn Chubbuck, ID 83202 208-237-2430 Ext. 145
