Community drinking water results from the additional drinking water testing following the 2023 wildfire season
Overview
This page shows the results of additional drinking water testing done in 2023 and 2024 after the wildfire season. Results are grouped by community and include both raw (untreated) and treated (drinking) water samples.
About the substances tested
The following substances were tested as part of this initiative:
- Nutrients: Ammonia, Nitrite, Nitrogen (Total), Phosphorus
- Minerals: Calcium, Potassium
- Disinfection by-products: Haloacetic Acids (HAAs)
- Other chemicals: Per- or Polyfluoroalkyl Substances (PFAS), Polycyclic Aromatic Hydrocarbons (PAHs)
- Water chemistry indicators: Conductivity, Cation/Anion balance, Electroneutrality
Some of these substances can affect health if present at high levels over time. Others are not linked to health risks but help assess how well water treatment systems are working.
How to read the tables
- Raw water means untreated source water entering the water treatment plant.
- Treated water means water that has gone through full treatment and is safe to drink.
- Not detected means the substance was not found above the laboratory detection limit.
- Greyed-out cells mean the sample was not received or could not be analyzed due to lab issues.
- Crossed-out cells mean no test was requested - some substances were only tested in treated water because they are only a concern when consumed.
