A failure at the South Water Treatment Plant for the City of Marco Island caused a pump to shut down and dropped water pressure, prompting a boil water advisory for the southern part of the island.
The notice, issued March 30, was rescinded as of 10:30 Monday morning.
The area impacted in the southern part of the island included areas west and south of the Winterberry Bridge, and south of Winterberry Drive and South Barfield Drive.
Any time the pressure in the water lines that transport potable water falls below 20 per square inch, a boil water notice is issued as a precaution, even when contamination is unlikely.
A city notice said the precautionary notice will be in place until water samples can be collected and analyzed, which can take 48 hours. Testing is done due to chances that the loss in water pressure could allow harmful bacteria to enter lines.
The water tests came back clear.
A boil water notice means tap water should not be used for drinking, cooking, or ice-making until tests verify the water meets all standards.
During the testing period, any tap water used for drinking or in anything that humans and animals ingest, should be vigorously boiled for at least one full minute. The boiling kills any microorganisms that may be present.
