Changes in water chemistry, such as increased dissolved organic carbon concentrations, or increased iron and manganese concentrations.

This may lead to larger amounts of sludge stuck in water filters or more chemicals needed for water treatment, all of which would raise operating costs

Increased turbidity (water cloudiness).

More algal blooms in reservoirs, causing health effects, taste and odor.

More debris in water reservoirs, causing damage and higher maintenance costs.

The following problems may impact a drinking water system long after the wildfire is over: ash) to wash into downstream drinking water supplies. Burned land and forests near water can cause large amounts of hanging or dissolved material (e.g. during intense rainfall events in the fall/winter months). For some communities, problems may appear long after the wildfire is over (i.e. It is hard to predict the long-term impacts of wildfires on drinking water quality. What are the long-term impacts to my water quality?

If there is skin contact with fire retardants, wash the area with soap and water, and launder any clothing prior to wearing. Drug and Poison Control Center for advice at or call 1 800 567-8911.

However, you should contact a physician or B.C. If inhaled or ingested, immediate first aid is not likely required. People and pets should avoid direct contact with fire retardants. (Cloudy or unclear) Turbidity Nitrite - 3 mg/L nitrite or 1 mg/L as nitrite-nitrogen.Nitrate - 45 mg/L as nitrate or 10 mg/L as nitrate-nitrogen.

Water should meet the following guideline levels: To make sure water is safe, drinking water from sources where fire retardant chemicals were used should be checked to ensure that it meets the Guidelines for Canadian Drinking Water Quality. Where fire retardant has entered into drinking water sources, it is likely the amounts will be so small that it is not a human health concern. For more information, see HealthLinkBC File #05a Nitrate in Well Water. If fire retardant gets into surface water that is used for drinking water, it may cause temporary increases in nitrate/nitrite levels and/or water cloudiness. This adds a red color, so the fire fighters can see where it is dropped. A nitrogen-based product, similar to fertilizer, is added along with small amounts of additives to make it fight fires better. The most commonly used fire retardant in B.C. When good practices are followed, there is little risk to human health and the environment. The use of fire retardants to fight wildfires is common in B.C. Can fire retardant affect my drinking water? This could allow pollution to enter the system, or lead to stagnant water lines that may need to be flushed. These may interrupt normal treatment practices, or cause loss in water pressure. building, water intake valve, water well head, treatment system, piping, etc.) Electricity/power outages or fire damage to structures (e.g.Changes in water appearance, clarity, colour, smell and/or taste.Fires at or upstream of your water intake.lake), some signs your water supply may have been impacted by wildfires include: If your drinking water comes from your own private well or surface water source (e.g. If there are concerns, they should communicate with you. If you are on a community water system, your water supplier should check your water system and the quality of your drinking water. How do I know if my water quality has been affected? The level of impact depends on the power and size of the fire, the weather, type of landscape/geography, and the ecosystem where the water comes from. These changes can make it harder for the local water treatment system to work in making your drinking water safe.

If fire retardant is present, there may be a possible rise in soil and water chemical levels, such as: phosphate, nitrate, and nitrite.

Changes in taste, colour and smell of drinking water.

Changes in water quality from build-up of ash, soil erosion, and fire debris.

Changes in the amount and timing of snowmelt and runoff from storms.

Possible effects of wildfires on drinking water include: How can wildfires affect drinking water quality? When wildfire affects the trees, soil and vegetation surrounding these areas, it can be difficult for that water ecosystem to maintain good water quality. For example: nearby streams, rivers and lakes. Wildfires can impact water sources used for our drinking water.
