Butner, NC. September 4, 2020  — Congratulations to SGWASA Executive Director Scott Schroyer, Utilities Operations Director Fred Dancy and the dedicated SGWASA water treatment facility employees for once again achieving success in meeting the North Carolina Drinking Water Standards for Disinfection By Products (DBP).

What are DBP’s and TTHM’s?

DBP’s: Disinfection by-products (DBPs), also called trihalomethanes, are formed when chlorine and bromine interact with natural organic materials in water, such as in chlorinated drinking water and chlorine-treated swimming pools. DBPs can be found in the air during activities such as showering, bathing, dishwashing, and swimming. DBPs do not build up in the environment.

TTHM's: Trihalomethanes (THM) are a group of four chemicals that are formed along with other disinfection by products when chlorine or other disinfectants used to control microbial contaminants in drinking water react with naturally occurring organic and inorganic matter in water.  The EPA regulates total trihalomethanes at a maximum allowable annual average level of 80 parts per billion (0.080 MG/L).

SGWASA Executive Director Schroyer commented, “Consistently achieving low values quarter after quarter for the past three years to be in compliance with the EPA is excellent in terms of SGWASA providing quality drinking water to its customers.”

Thank you to everyone involved for keeping SGWASA among the best in our area.

Jimmy Gooch, SGWASA Board Chairman
