When a PWS fails to meet the required Disinfection By-Product Precursor removal percentage between the source water and the treated water it must issue a public notice to inform the consumers of its water that Total Organic Carbon (TOC) is not adequately removed and this is a treatment technique violation. You can use this template as a guide to prepare that public notice.
