Fort Irwin’s Water System is operated under a privatization contract with CH2MHill.  As the system ownership is not transferred to CH2MHill, compliance responsibilities still reside with the U.S. Army.

Fort Irwin has recently completed the Year 2016 Water Quality Report for Fort Irwin.
CH2MHill routinely monitors (on behalf of Fort Irwin) for constituents in the drinking water according to Federal and State laws.  The full results of the monitoring for the period of January 1st through December 31st 2016 are available on the web at This website also contains previous year’s reports.

The Year 2016 Water Quality Report meets all requirements for the Consumer Confidence Report for 2016. The Environmental Protection Agency and the State of California Title 22 requires that this report be prepared and posted by the community water system on an annual basis to keep the public informed. 

Fort Irwin Water system has undergone extensive changes since the last report. Fort Irwin completed construction of a new water treatment plant, Irwin Water Works (IWW), last year. The plant began treating some of the water provided to our residents in May 2016. Beginning 1 July 2016, all water provided to Fort Irwin was treated at IWW and is fully potable. Fort Irwin also began to decommission the old Reverse Osmosis (RO) plant and system in September 2016 by connecting the Domestic Uses (DU) system to the RO system and decommissioning the RO plant. The finishing steps in this transition will be occurring during the summer of 2017. Fort Irwin is required to report all the water quality results taken during 2016. Fort Irwin’s report contains information on the source of the water and any contaminants that may be present in the source water. For example part of last year the water provided in the Domestic Use (DU) water system exceeded the maximum contaminate limits for Arsenic and Fluoride. All water provided after 1 July 2016 and Reverse Osmosis (RO) water provided at small taps and water fountains is safe to drink.

This report’s purpose is to improve public health protection by providing educational material to allow consumers to make educated decisions regarding any potential health risks pertaining to the quality, treatment, and management of their drinking water supply.
