Does your water smell or taste a bit "off" sometimes?

As you turn on the tap in the late fall and early winter months you might notice a bit of a musty odor or an earthy “flavor” to your usually sparkling glass of PID water.

While water quality tests tell us our water is safe to drink and meets all EPA standards, we’re not any happier than you are with water that doesn’t meet our usual high flavor standards.

Two compounds released from soil and algae, methylisoborneol (MIB) and Geosmin, can be detected by humans at levels of less than 10 parts per trillion (one part per trillion would compare to one inch in 16 million miles).

MIB is most commonly found in the bottom layers of lakes; Geosmin is the substance that gives soil its “dirt” smell. Together, these two lend a temporary and undesireable “bouquet” to our PID water when levels are high in the water we use from Magalia Reservoir. Paradise Lake, because it’s deeper, hasn’t so many issues because the water is colder and therefore “fresher” in odor and taste.

When the seasonal rains begin in late fall, the District goes to work at refilling our reservoirs. It becomes a complex balancing act of slowing the discharge from Paradise Lake (so it can refill for the next year) and using a blend of water from the lake as well as Magalia Reservoir to supply the treatment plant—and our users.

When we have an early rainstorm, the runoff water entering the magalia bypass pipeline overwhelms the amount of water and changes its chemistry. State health standards force us to use water from the magalia reservoir (which remains treatable) but there are taste and odor issues even though the water is safe to drink and use.

Fluoride

PID does not add fluoride to the water.

Chlorine

PID uses chlorine during its treatment process to kill disease-causing organisms. The water leaving the treatment facility has a small amount of chlorine residual sufficient to keep water safe and healthful while it travels the distribution system until it reaches your home. 

While the state allows higher levels of chlorine,  the district typically distributes water with a low chlorine residual ranging from 0.2 - 0.8 ppm.

A simple water pitcher with a built-in filter can improve the flavor of the water for those individuals sensitive to the taste of the treated water.

Water testing frequency

Each day, PID tests your water to make sure it is clean, safe and healthful before it leaves the treatment plant to be delivered to your home. Employees also perform weekly tests within the distribution system to ensure the water remains so during delivery. The consumer confidence reportwe publish each year provides more information on these tests results and additional water testing we routinely perform.
