[ARCHIVED] Water Quality Public Notice

Public Notice Graphic


Public Notice

July 24, 2023

It has been determined that slightly elevated levels of manganese are causing a slight discoloration of household drinking water in the Godley area. Preliminary sampling has indicated small levels of manganese that are consistent with the appearance of a yellowish color. Manganese is not a regulated constituent in water supplies and is deemed as a secondary standard by the EPA meaning elevated concentrations may result in discoloration and possible taste issues but does not pose a risk to health. All other routine water quality sampling has not indicated anything that is known to pose a risk to health.  So, while the water is slightly discolored, the water is still safe.

Lake Granbury is beginning to de-stratify due to higher temperatures, which is the process in which cooler water at the bottom of the lake becomes warm and rises into the upper parts of the lake. When this happens, manganese, which is found at higher concentrations at the bottom of lakes, is then stirred up into the upper level of the lake. This condition should be temporary and should clear up as the Lake Granbury begins to settle.

We are searching for ways to better remove the manganese from the water with current treatment processes on hand. We will also be monitoring concentration levels along with our other routine water quality sampling. In the event there is an adverse change we will notify you promptly.
