Abfa Says Tap Water Safe, Increases Chlorine Levels

The water industry has raised chlorine levels by 40% in piped water to help fight the Covid-19 pandemic, head of Hygiene Department at the Tehran-based National Water and Wastewater Engineering Company of Iran (Abfa) said.
“This was done based on international health protocols and does not pose any health hazard,” Koushyar Azam Vaqefi was quoted as saying by ISNA.
In normal conditions utilities adjust maximum chlorine levels at 0.7 milligram per liter. Nonetheless, since the outbreak of coronavirus in January, Abfa has gradually increased the level to 1 milligram, up 40%, he added.
Reassuring that at this level, no harmful health effects could occur, he said, “Chlorine levels up to 4 mg/l or 4 parts per million (ppm) are considered safe for drinking water. But there will be no need to add that amount of chlorine to tap water.”
