LAPLACE — A boil-water advisory has been issued for Chantilly Drive to St. Andrews Boulevard on Belle Terre Boulevard in LaPlace, according to St. John the Baptist Parish officials.

The emergency action was caused by a large main water leak on Belle Terre Boulevard.

Residents in the impacted area are advised to purify their water before consuming it or using it for food preparation.

To purify, boil water for one minute in a clean container. Parish officials said the one-minute boil time begins after the water has been brought to a rolling boil.

Protocol following a loss of pressure to the system requires testing of a water sample by a state-certified lab. The sample must be incubated for 24 hours before the test is administered. Test results are sent to the Parish and Department of Health. If no contaminants are identified, the boil water advisory is lifted, usually, within 48 hours.

“It is safe to bathe, wash clothes and wash dishes during this time,” a Parish statement reads. “When the boil water advisory is lifted, notifications will be posted online at www.sjbparish.com and sent to affected area.”

Emergency repairs to a large main water leak on Belle Terre Boulevard have been completed, and Parish officials said water pressure is returning as of 2 p.m. Wednesday.
