Louisville Water Scientists and Plant Operators Responding to Drought Conditions

Monday July 23, 2012

With the hot weather and drought conditions, algae forms in the Ohio River. The sunlight penetration of the still water promotes blue-green algae growth and associated organic compounds, known as MIB (Methyl-Iso-Borneol) and Geosmin. These compounds can cause taste and odor issues in our drinking water, the most common description is a musty or earthy taste and smell.

This is not a health issue. Our water meets all EPA water quality regulations. The water is safe to drink.

Customers can chill their drinking water in an open container. This will help improve the taste of the water. Public health is our number one responsibility - our customers and we expect good-tasting water.

Every summer we monitor river conditions for algae and when we encounter it, we treat with Powdered Activated Carbon (PAC) to absorb the organic compounds from the water. We have the ability to remove 90 to 95% of these compounds. You'll notice the Crescent Hill Reservoir is black, this is from the PAC. It is filtered from the water before it enters the public supply.

While much of the US - and the state of Kentucky deal with drought conditions, we are fortunate to have the Ohio River - it's an abundant supply. Louisville Water customers don't have to worry about water supplies.
