Clarks Hill, South Carolina

A boil water advisory has been issued for portions of McCormick County, South Carolina, affecting residents in various areas, including Clarks Hill. The advisory commenced on Friday, January 3, 2026, and remains active. Residents are urged to boil all tap water vigorously for at least one minute before consumption or use in food preparation to ensure safety. This precautionary measure is in place until further notice and is essential for preventing potential health risks associated with waterborne contaminants.

Understanding the Advisory

The advisory means that the water supply in affected areas may be contaminated, though officials have not yet released the specific cause for this particular advisory. Boil water advisories are typically issued when there is a possibility that harmful bacteria or other microorganisms could enter the public water system. Common reasons for such advisories include significant water main breaks, widespread loss of water pressure, complications at water treatment plants, or the detection of contaminants through testing. For example, in the past, McCormick County has issued boil water notices after E. coli was found in water tests. However, the specific reason for the current advisory has not been detailed.

Guidelines for Residents

During a boil water advisory, all water intended for drinking, cooking, making ice, brushing teeth, washing dishes, or preparing baby formula should be boiled. Bringing water to a rolling boil for a full minute is sufficient to kill most bacteria and viruses. After boiling, the water should be allowed to cool before use. Bottled water is also a safe alternative during this period. It is advised to avoid using appliances that rely on drinkable water, such as ice makers and coffee makers, during the advisory. When bathing or showering, generally these activities are considered safe, but care should be taken to avoid ingesting the water.

To ensure the safety of food service establishments, they are advised to follow all applicable state and federal regulations during a boil water advisory.

Lifting the Advisory

A boil water advisory is a precautionary measure that remains active until water samples can be collected and tested to confirm the absence of harmful bacteria. These tests usually take a minimum of 16 hours to process. Once test results confirm the water is safe, the advisory will be officially lifted. Residents will be notified when the advisory is repealed, and at that point, they may return to normal tap water usage. After an advisory is lifted, it is often recommended to flush water lines by running cold water taps for a few minutes to clear any stagnant water.

The South Carolina Department of Health and Environmental Control (SCDHEC) provides guidelines and information regarding boil water advisories, emphasizing the importance of public safety during such events. Residents should continue to monitor local announcements for updates specific to the McCormick County advisory.
