Cheat sheet: Everything LA residents need to know about water advisories

Water Advisories Issued Due to Wildfires in LA County

Water departments in Los Angeles County, including the Los Angeles Department of Water and Power (LADWP) and Pasadena Water and Power (PWP), have issued water advisories for residents near the Palisades and Eaton fires. These notices are due to the potential contamination of the water system as a result of the fires.

How to Determine If Your Home is Under a Water Advisory

To check if your home is under a water advisory, first identify the water department serving your area by checking your water bill. If you are a renter, ask your landlord for the information. The advisories are specific to different areas, and the notice will inform you about the type of advisory in place.

Types of Water Advisories

There are three types of advisories currently in effect due to the wildfires:

1. Boil Water Notice

   • This advisory means it is not safe to drink or use the water without boiling it first. According to LADWP guidelines, a Boil Water Notice is issued when "the water supply has a microbiological contaminant that can be rendered safe by boiling the water or by using bottled water." LADWP advises to bring the water to a full rolling boil for at least one minute before using it, and let it cool for about 30 minutes before storage[5].

2. Do Not Drink Notice

   • This notice means you should not drink the tap water at all, as the contamination is severe and cannot be made safe by boiling or disinfection. Agencies will issue this notice when "the water supply has an acute contaminant that cannot be rendered safe by boiling the water or by disinfection, or is an unapproved source with no water quality data," according to LADWP[5].
3. Do Not Use Notice
   • This advisory means you should not use the tap water for any home activities, including showering, hand washing, drinking, food preparation, or washing dishes. Local water departments advise using bottled water only for all of your water needs[5].

Guidelines for Each Advisory

Boil Water Notice

• Drinking and Baby Formula: Use pre-boiled or bottled water.
• Showering and Bathing: The water in your home may be used for showering, bathing, shaving, and washing as long as you take care not to swallow any water. Limit your time in the bath or shower to minimize contact with the water. Immunocompromised individuals or those with chronic illnesses should use boiled, then cooled water to bathe—sponge bathing is advisable.
• Washing Dishes: Hand-wash with pre-boiled water. Alternatively, rinse your dishes with a diluted bleach solution (1 tablespoon of unscented bleach per gallon of water) after washing them with dish detergent. It’s fine to use the water for home dishwashers as long as the hot wash is at least 170° F and includes a full dry cycle. Commercial dishwashers that are National Sanitation Foundation listed are also safe to use.
• Washing Clothes: It’s safe to use a washing machine for laundry as long as the clothes are fully dried before being worn.
• Washing Vegetables and Other Food Prep: Wash them with boiled, then cooled water.
• Brushing Teeth: Use pre-boiled or bottled water.
• Washing Hands: It’s okay to wash them with tap water as long as you wash vigorously with soap. If you’re washing your hands to prepare food, use bottled or pre-boiled water.
• Water for Pets: Pets can drink pre-boiled or bottled water. For more specific information, contact your vet[5].

Do Not Drink Notice

• Drinking and Baby Formula: Do not use tap water at all, even if it is boiled. Use bottled water for drinking and making baby formula.
• Showering and Bathing: Using tap water to bathe is safe, but be careful not to swallow the water or let it come into contact with nicks, cuts, or open wounds. Sponge bathing is advised. Limit your time in the bath or shower, and do not take hot baths. Use lukewarm water and ventilate the area.
• Washing Dishes: Use bottled water. If you’re using a dishwasher, use the air-dry setting.
• Washing Clothes: It’s okay to use cold tap water to wash your clothes. If your clothes dryer does not vent outside, avoid using it and dry your laundry indoors.
• Washing Vegetables and Other Food Prep: Use bottled water for washing or handling food and for making ice. Do not use automatic ice makers.
• Washing Hands: It’s safe to wash them with tap water as long as you wash vigorously with soap. If you’re washing your hands to prepare food, use bottled or pre-boiled water.
• Water for Pets: Use bottled water.
• Swimming Pools and Hot Tubs: Do not use them[5].

Do Not Use Notice

• This notice means you should not use the tap water for any home activities, including showering, hand washing, drinking, food preparation, or washing dishes. Local water departments advise using bottled water only for all of your water needs[5].

Accidental Consumption of Tap Water

Under any of these advisories, LADWP states the likelihood of becoming sick is low, but still possible, especially for those who are immunocompromised or have a chronic illness. If you have any symptoms of gastroenteritis, including diarrhea, nausea, vomiting, or abdominal cramps with or without fever, seek out medical attention[5].

Is My Home Filter Enough?

No, your home filter is not designed to filter out the types of bacteria produced by wildfires. According to Newsha Ajami, a hydrologist, average home filters are built for metals and toxins commonly found in tap water but not for the contaminants introduced by wildfires[5].

How Does Water Contamination Happen?

Water contamination from wildfires occurs through several methods. The high usage during firefighting can lead to a decrease in water pressure, causing leaks in pipes. These leaks can suck pollutants and toxins back into the water system. Debris can also make its way into groundwater, and overheated pipes can melt and affect the efficiency of entire water systems[5].

Expecting Updates

Expect notices to be updated every two days. LADWP will inform residents when tests show that water is safe to drink, which takes a minimum of 48 hours to complete according to public safety protocols. For Do Not Drink notices, agencies face challenges in estimating how long the advisories will remain in effect due to changing conditions and flushing the system to meet standards[5].

Where to Get Bottled Water

Potable water is available at several locations:

• 450 N. Lake Avenue, Pasadena, 91101 (Tuesday, January 14, from 10 a.m. to 3 p.m.)
