South Pasadena residents are noticing cloudy and discolored tap water from their faucets, an issue that is causing health concerns. Reports of yellow or brown water began in March, and have been concentrated in the central and eastern parts of the city.
Residents who first started noticing the concerning phenomenon took to the online neighborhood forum Nextdoor to voice their concerns. In a thread with more than 60 responses, residents began to notice a pattern, starting roughly two weeks ago.
[The water] starts with brown color, then yellow, then normal clear color… It stained part of my bathtub,” resident Sabina Langan said.
The city received ten reports in March and twenty reports in April and responded by testing water quality at affected sites and attempting to clear pipes. Residents dealt with the issue by running water through a faucet until it clears up, drinking bottled water, or using a water filter.
“I am changing my water consumption habits by letting my water run for a few minutes prior to use if I find the discoloration severe,” resident John Woo said. “The severity of the discoloration seems to change on a daily basis.”
According to the city, the discoloration is due to a blending of groundwater with surface water from the Metropolitan Water District (MWD) for the purpose of meeting a new regulation. Due to a reaction between the types of chlorine in the new blended water, the water is reacting with the city’s water mains and residential pipes and causing changes in clarity and odor.
The Water Division assured that the water is still harmless, and meets or exceeds both federal and state standards. In an attempt to alleviate the changes, the city has flushed water through pipes and fire hydrants. However, residents claim that the flushing did not improve water quality.
“Although the City flushes the water mains, the effects are predominately experienced by dwellings with old galvanized piping, especially apartment units where water tends to [stagnate] in the pipes,” Acting Public Works Director Rafael Casillas said.
