Why water in California’s capital is now stinking | Climate crisis in the western United States

Sacramento waters, CaliforniaHas always received calls from relevant residents reporting the strange taste and smell of water coming out of the tap. A naturally occurring compound called geosmin can give water a rustic taste when the water level is low and the temperature is high.

Water is not dangerous, but it smells. Complaint calls usually do not start until the end of autumn or summer. But this year is different, thanks to the worsening drought that has hit the region hard.

The city’s water quality supervisor, Mark Severide, says the temperature is hotter and the water level is lower than most people remember. “That’s why we’re experiencing an early onset of this problem. It’s a problem the city has been telling people for years,” he says.

Due to this situation, the city issued a statement that it was safe to drink water, urging residents to cool the water or add a little lemon to hide Muskines.Suggestion Raised eyebrowsHowever, authorities want to ease people’s fears, saying the situation is reminiscent of the day-to-day challenge of dealing with extreme droughts.

Changes in water quality are not limited to Sacramento.Other Districts throughout California reported concerns about The taste and smell of waterThis problem is one of several symptoms of a drought disaster, especially during the dry season. In other areas, wells are expected to dry out and more than a million Californians already have no access to safe drinking water. According to a report issued by the State Water Resources Management Commission this year, 620 public water systems and 80,000 domestic wells were at risk of failure.

Geosmin is a compound produced by living organisms Underwater water level is not dangerous, But they are not filtered during purification.

“This water meets or exceeds all federal water quality guidelines. It’s safe and healthy to drink,” says Severeid. “We are dealing with very low concentrations. We are talking about geosmin concentrations in the one billionth range-very small amounts,” he adds. “But people are very sensitive to changes in the taste, smell and temperature of water.”

Geosmin is produced by blue-green algae that breed when the water level is low and the temperature is high. Filtration takes care of algae, but does not catch strange-tasting compounds. The drought produced record highs and record low discharges from raw water. This complicated the problem and created early arrivals. This issue can continue throughout the year.

Carlos Eliason, a spokesman for Sacramento’s utility sector, states that as a city resident, he himself experienced the problem. “It smells almost like Petrichor,” he says, explaining the same odor that can often be detected after the first rain following dry weather.

Adding lemon may help for now, but plans are being implemented for a more robust response. According to Severide, the area has begun a planning process to rethink water treatment over the next 50 years, and filtration to remove compounds that cause taste and odor is one of the top priorities.

According to Eliasson, the plan focuses on improving water treatment in the face of bad weather and strengthening resilience to the threat of drought and wildfires that are expected to be exacerbated by climate change.

“Obviously, we are experiencing it in real time,” says Severide. “Low flow, high temperature – many complaints. After discussing this with people for hundreds of years, we got tired of it.”
