What causes the "earthy taste" that sometimes affects our water?

Earthy and musty odors are usually caused by algae in our raw water that produce two compounds: Geosmin, which causes earthy tastes and odors, and 2-methylisoborneol (commonly referred to as MIB), which causes musty odors. The algae that produce these compounds are normally present in the summer when conditions are warm and better-suited for algal growth. These compounds are very difficult to remove during the purification process and while some people find the taste unpleasant, they are not harmful when consumed. Our treatment process utilizes powered activated carbon (PAC) and we actively manage our raw water sources to minimize algal growth.
