Ascension Parish officials said Monday a boil water advisory will remain in effect for the small Mississippi River community of Lemannville at least until results from key water quality tests arrive Tuesday.

Officials announced the boil water advisory late Saturday night after a vehicle hit a fire hydrant in St. James Parish.

That part of Ascension Parish’s west bank, which is downstream from Donaldsonville along La. 18 and north of the Sunshine Bridge, is supplied by St. James Parish government’s water system.

Ken Dawson, Ascension Parish chief administrative officer, said in a statement Monday that the damaged fire hydrant in St. James was on the same water line that supplies Lemannville in Ascension.

Though the line in Lemannville did not lose pressure, Ascension officials issued the boil advisory because the crash and repairs to the hydrant still compromised the waterline, Dawson said.

Parish officials have said residents who live in Lemannville — they are customers of Ascension Consolidated Utilities District No. 1 — can consume their tap water after boiling it for at least 20 minutes.
