Some water customers in North Richland Hills have noticed changes in the taste and odor of their drinking water recently. This occurs when there is an increase in organic compounds (Geosmin or 2-Methylisoborneol) that are naturally occurring in the water supply. While these compounds have an earthy or musty odor, they are non-toxic and safe to consume. The same compounds are also present in beets, spinach, mushrooms and other foods.
Heating your water increases the release of organic compounds, which explains why the smell is more easily detected when in the shower or when used for hot beverages. Chilling your water may make the smell less detectable.
According to the Trinity River Authority (TRA), which supplies water to the City of North Richland Hills, it is a normal occurrence for there to be an increase in organic compounds in area lakes this time of year. TRA is making adjustments to its treatment processes to reduce the taste and odor issue.
