By July 1 of each year, the City of Greenbrier is required to notify customers about the quality of the drinking water including a summary of the results of the tests that are performed. The notification, the Consumer Confidence Report (CCR), is printed in the Robertson Count Times. Physical copies can be obtained at City Hall. The CCR provides information for the previous calendar year. It also contains general information about the water system as well as technical information about the analyses that are performed on a routine basis.
