A natural phenomenon may make drinking water cloudy for North Marin Water District (NMWD) customers in West Marin. The occurrence is the result of air dissolved in the water and is not uncommon during wet seasons. This spring has been especially rainy, resulting in high flows in Lagunitas Creek, which is adjacent to the district’s water supply. Pressure caused by high water levels, combined with cold temperatures, makes the water capable of holding and dissolving significant amounts of entrapped air. By the time the water gets to the faucet, it may look similar to carbonated soda. For clear drinking water, the district suggests letting the water sit for a few minutes. While the water is safe to drink, the district has increased testing to assure its high quality.
