Water Quality Reports
GCWW publishes an annual Water Quality Report for its customers. Updated by April 1 of each year, this publication complies with the U.S. EPA's National Primary Drinking Water Regulation for Consumer Confidence Reports.
On average, GCWW treats about 132 million gallons of water a day on average and conducts about 600 tests daily throughout the water treatment and distribution process. Monitors and alarm systems are also located throughout the treatment plants and in the distribution system to continuously monitor water quality.
These tests include:
• Source water is tested routinely before it enters treatment plants.
• Treated Water is tested after each step in the treatment process.
• Water from the distribution system is sampled and analyzed regularly.
The Ohio EPA reviews test results on a monthly basis, and every year, GCWW water meets or exceeds all state and federal health standards for drinking water.
GCWW draws its water from the Ohio River and the Great Miami Aquifer near Fairfield and uses state-of-the-art water treatment technology including:
• Sand filtration
• Granular Activated Carbon adsorption (GAC)
• Powdered Activated Carbon (PAC)
• Ultraviolet disinfection (UV)
