Boil Water Advisory – EFFECTIVE 09/01/2022


City of Mount Pleasant Did Not Meet Treatment Requirements


Our water system recently violated a drinking water standard. As our customers, you have a right to know what happened, what you should do, and what we did to correct this situation.

We routinely monitor your water for turbidity (cloudiness).  This tells us whether we are effectively filtering the water supply.  Normal turbidity levels at our plant are .03 turbidity units.  A water sample taken on September 1, 2022, showed levels of 1.99 turbidity units.  This was above the standard of 1.0 turbidity units.  Because of these high levels of turbidity, there is an increased chance that the water may contain disease-causing organisms.  Out of an abundance of caution and to ensure our customers are aware of the situation, we are issuing this notice. 

What should I do?

DO NOT DRINK THE WATER WITHOUT BOILING IT FIRST. Bring all water to a boil, let it boil for one minute, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and preparing food. Boiling kills bacteria and other organisms in the water. Continue using boiled or bottled water until further notice.

People with severely compromised immune systems, infants, and some elderly may be at increased risk. These people should seek advice about drinking water from their health care providers. General guidelines on ways to lessen the risk of infection by microbes are available from EPA’s Safe Drinking Water Hotline at 1 (800) 426-4791.

What does this mean?

Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches. These symptoms are not caused only by organisms in drinking water. If you experience any of these symptoms and they persist, you may want to seek medical advice.

What happened? What was done?

A problem occurred with the treatment system at the water plant. During water plant start up, high turbidity water passed through the filters due to operator error and entered the distribution system.  There may be an increased chlorine smell or discoloration in your water due to corrective actions taken by the water department.  Samples will be taken every 24 hours beginning Friday, September 2nd and again Saturday, September 3rd.  Two consecutive clear samples will be required to lift the boil water advisory. 

The health and safety of our residents is our top priority.  For updates, please check the City of Mount Pleasant’s Facebook page and its blog at https:\\ or the community information phone line:  989-779-5320.
