Manganese in Treated Water Delivered by the Trinity River Authority 

Arlington-The presence of higher than normal manganese in treated water distributed to Bedford, Colleyville, Euless, Grapevine and North Richland Hills by the Trinity River Authority of Texas has caused a light yellow or brown color to be noticeable in some of the water being delivered.    

Manganese is an essential trace nutrient for plants and animals and poses no health risk to humans. Manganese is also a naturally occurring substance and is present in the lake water treated by TRA.  

This condition has occurred in past years and may also be associated with taste and odor issues.  Ozone disinfection equipment is currently being installed in the TRA water treatment facility which will significantly reduce future water staining and taste and odor incidents.           

While undesirable, manganese poses only aesthetic problems, which will ultimately pass through the distribution system and no longer be noticeable by the public.
