BEVERLY — A 24-hour boil order enacted Thursday for thousands of Beverly and Morgan Park homes has been lifted, officials said Friday morning.
Residents should run all cold-water faucets for five minutes before resuming normal use, officials said.
City officials said a “power outage” caused a loss of water pressure from 8:30-9:30 a.m. Thursday at the 110-year-old Roseland Pumping Station, potentially allowing bacteria to contaminate water mains.
The order was lifted after microbiological samples analyzed by the Department of Water Management’s Water Purification Laboratories verified that the water is safe to drink, officials said in a statement.
Andrea Cheng, acting commissioner of the Department of Water Management, blamed the outage on ComEd maintenance in the area and pledged a full investigation.
The boundaries of the boil order were east of Sacramento Avenue, north of 119th Street, west of I-57 and southwest of Beverly Avenue. Residents in these areas can now use their water normally, but first should follow these guidelines, the water department said:
The Department of Water Management advises the following after rescinding a boil order advisory:
- Flush all faucets. Run all cold-water faucets for 5 minutes. Instructions for intensive flushing can be found here.
- Flush drinking fountains by continuously running for 5 minutes.
- Flush automatic icemakers. Make 3 batches of ice and discard all 3 batches.
- Drain and refill hot water tanks.
- If you have a water softener, run water through a regeneration cycle.
- If you have a point of use or inline water filters, sediment and/or Reverse Osmosis systems perform the recommended filter change or back-wash in accordance with the manufacturer’s specifications.
- Drain reservoirs in large buildings that have water-holding reservoirs.
- Flush water coolers: run coolers with direct water connections for 5 minutes.
- Re-start and flush any water-using fixture in accordance with the manufacturer’s specifications.
Rich Negrin, vice president of external affairs for ComEd, said at a joint news conference with city officials the routine maintenance work was not being done at the pumping station, 347 W. 104th St., but it somehow impacted the facility.
Negrin disputed the problem was caused by a “power outage,” saying all four power lines headed into the pumping station remained fully charged.
“The question is whether some of the maintenance that occurred had an impact on some of the city’s equipment,” Negrin said. “We responded immediately to make sure and try to investigate what was going on in terms of the fluid situation as it evolves…we’ll figure out what this issue is and obviously offer whatever assistance we can to make sure everything is repaired.”
