LOUISVILLE, Colo. (KDVR) — Update, Jan. 6. 7 p.m. The boil advisories for Louisville, Superior and Sans Souci have been lifted.

Original: Both Louisville and Superior are currently under a boil water advisory following the devastation left behind by the Marshall fire, impacting the water supply.

Louisville and Superior changed their water supply to untreated water to make more water available to fight the fires, according to the Colorado Department of Public Health and Environment.

“As soon as the fires are extinguished or controlled, and people can safely come back to their homes, CDPHE will coordinate with the city to flush and test the water to make sure it’s safe to drink again,” CDPHE said in a news release.

Louisville’s advisory was sent out Thursday evening while Superior’s was announced Friday morning.

What to do during a boil advisory

Anyone in Louisville or in Superior is advised to use bottled water or boil any water that will be used for drinking (including for pets), making ice, brushing teeth, washing dishes or food preparation.

The Colorado Department of Public Health and Environment released this information on how to respond to the boil advisory:

  • Bring water — including filtered water — to a boil, let it boil for three minutes and then let it cool before using.
  • Do not use water from any appliance connected to your water line, such as ice and water from a refrigerator.
  • Showering in the water without boiling it is OK, but do not swallow any water. Use caution with babies and young children; consider sponge baths.
  • Breastfeed infants or use ready-to-use formula, if possible.
  • If you experience symptoms like nausea, cramps, diarrhea and associated headaces, seek medical advice.
