Water pressure dropped below the acceptable level of 15 psi. This advisory will be in effect until further notice. The East bank of Orleans Parish is not affected by this. Residents in the affected area are advised not to drink, make ice or brush teeth until further notice. Residents who have compromised immune systems are advised not to wash hands, shower or bathe. All other residents are advised to take the following precautions: -Wash hands: Use soap and water, dry hands, then apply hand sanitizer. The safest option is to wash with boiled or bottled water. -Shower or bathe: Be careful not to swallow water while showering or bathing. Use extra caution when bathing infants and young children. A sponge bath can reduce the chance of swallowing water.
