Advertisement 'Do Not Drink' advisory lifted for North Sacramento residents Cause of contamination is still unknown Share Shares Copy Link Copy

City officials lifted the “Do Not Drink” advisory for some residents in a North Sacramento neighborhood Wednesday afternoon.Late Tuesday night, utilities officials posted signs on the doors of people living between Main Avenue, Norwood Avenue, Pell Drive and Interstate 80 saying not to drink the or use that tap water. Residents also reported that the water was purple.By 6 p.m. Wednesday, officials said there was no longer any contamination in the water and that it was safe to drink.“Flushing of fire hydrants in the area has resolved the color issue and the city continues to investigate the possible causes,” officials said in a statement. “Laboratory results indicate that water samples are normal.”The lab tested for iron, manganese, chlorine, pH, turbidity, color and bacteria. All results came back normal. However, the city only tested the water after it had been flushed and had not tested the purple water."Those items indicate to us that whatever the issue was, has passed," Sacramento Water Quality Superintendent Pravani Vandeyar said. "But until we identify the cause, we don’t know if it can reoccur."Late Wednesday utilities workers went door-to-door to as many as 1,000 homes, talking to residents and delivering flyers with information about the steps the city has taken.The city is looking into whether dye or chemicals somehow flowed back into the system from a business or some industrial use. More complex tests are still being processed, and the city plans to continue monitoring and testing the water for another week.The cause of the discoloration is still unknown.PREVIOUS STORY:Some residents in a North Sacramento neighborhood are being warned Wednesday morning to not drink or use tap water because of an undisclosed problem, the Department of Utilities confirmed with KCRA.Residents in a several block radius between Main Avenue, Norwood Avenue, Pell Drive and Interstate 80 woke up to a letter on their door warning of problems with the water.Officials with the Department of Utilities said they began receiving calls about 4 p.m. Tuesday of reports of purple water."An unknown substance has been added to the drinking water supplied by the city of Sacramento," said the letter, which was posted Thursday by the city of Sacramento. "(Residents are advised) to not use the tap water for drinking and cooking until further notice."The letter was posted on residents' doors between 10:30 and 11 p.m. Tuesday, but officials did not knock on doors because they didn't want to wake people up.The letter goes on to say that residents should use bottled water only for drinking, brushing teeth, washing dishes, making ice and food preparation "until further notice."Residents are urged to not treat the water themselves by "boiling, freezing, filtering, adding chlorine or disinfectants or letting water stand" because it will not make the water safe, the letter said."We will inform you when tests show that the water is safe again," the letter said. "We expect to resolve the problem within 24 hours. We will keep you informed as we gather information."The area receives its water from two wells, and no purple water was found in the wells. The issue is likely coming from the pipes that run from the wells to people's homes, according to water quality superintendent Pravani Vandeyar. The pipes range in age from more than 100 years old to pipes that are relatively new, she said."We’re not sure that this is a health issue because we still don’t know what caused the color. So, it’s difficult to say whether there is an impact if you’ve ingested water," Vandeyar said. "We’re thinking there’s probably no impact, but it’s difficult to tell that for sure."A variety of initial testing showed the water to be normal, said Vandeyar.Vandeyar said it's hard to tell what caused the purple water because they don't have sample of the purple water to test. Finding a cause could be like finding a needle in a haystack, she described. Water appears to be running clear Wednesday morning, but bacteriological test results won't come back until about 4:30 p.m., according to the Department of Utilities.The city is providing drinking water to the elementary school and the middle school in the area, and anyone else who needs drinking water can contact the Department of Utilities.Anyone with questions is told to call the following numbers:Water utility contact: 311 or 916-264-5011 (24 hours a day)California Division of Drinking Water: 916-449-5577Local County Health Department: 916-875-5881
