When algae dies, it gives off geosmin – a compound that negatively impacts the taste and odor of drinking water.
Water Department officials assure customers the water is safe for drinking, cooking, bathing and all other purposes, even though it may have an earthy smell and taste.
In an attempt to try to mitigate the issue, the department increased the dosage of ozone at the North Holly Water Plant. Ozone is used to disinfect the drinking water, and it can help with resolving taste and odor issues, but not in all cases. Very small amounts of geosmin can affect drinking water’s taste and odor.
Customers may try to improve the taste of their drinking water by:
- refrigerating the water in an open container
- adding a slice of lemon or lime.
