Water Quality Report

The City of Bedford is supplied with surface water from Lake Arlington through the Trinity River Authority's Tarrant County Water Supply Project and the 2 groundwater wells.

2019 Water Quality Report
This report describes the susceptibility and types of constituents that may come into contact with the City's drinking water source based on human activities and natural conditions. The information contained in this assessment will allow the City of Bedford to focus on source water protection strategies.

Safe Drinking Water Act

The Safe Drinking Water Act of 1972 (SDWA) is designed to protect drinking water quality and has broad authority to include surface and ground waters that have the potential to be used as drinking water sources. The Environmental Protection Agency (EPA) has the authority to establish and update specific standards for drinking water quality and is supported by the Center for Disease Control (CDC) and the Federal Drug Administration (FDA).

The EPA has specific federal limits for over 80 compounds referred to as the primary standards (MCLs) and having a known or suspected potential to create health-related impacts. Secondary standards (SMCLs) also exist and these are considered nuisance-related contaminants, such as taste and odor. Secondary standards are typically implemented voluntarily or by state rules. Bedford is a Superior Public Water Supply, which means that the water is treated to the secondary standards.

Trinity River Authority: Water Taste & Odor Notice

The Trinity River Authority (TRA) customers in the cities of Bedford, Colleyville, Euless, Grapevine and North Richland Hills may be detecting an earthy or musty taste in their tap water. Though this may be unpleasant, TRA assures its customers that their tap water is safe to drink.

The current taste and odor are being caused by the compound Geosmin (compound coming from algae) in TRA's raw water supply, Lake Arlington. Geosmin does not affect the safety of the finished tap water and is not a public health threat. Preliminary results from samples taken on January 9 indicate that the Geosmin concentration in raw water from Lake Arlington has begun to decrease.

Treatment for Taste & Odor

Currently, the primary treatment process for taste and odor at the TRA Tarrant County Water Supply Project (TCWSP) is ozonation. During events producing high concentrations of taste and odor from compounds such as Geosmin, the treatment is aided with the addition of hydrogen peroxide after primary disinfection is achieved.

Projected Raw Water Conditions & Its Effects on Taste & Odor

Lake Arlington's water temperature plays a key role in favoring algae populations that produce Geosmin. From past observations, Geosmin concentrations are highest after the lake temperature is below 10 degrees Celcius. Because of the recent warm, sunny days, there may be a retreat in populations of organisms producing Geosmin.

The TRA will continue to make modifications to the ozone feed at TCWSP to improve the sedimentation basins performance. Improved sedimentation will aid the removal of a large portion of the Geosmin. Taste and odor concerns are elevated because even in low concentrations, the taste and odor produced by Geosmin is readily noticed, however the TRA is closely monitoring the raw and finished water and are applying all appropriate resources toward removing the taste and odor causing compounds.
