Where Do We Get Our Drinking Water?

Bastrop drinking water comes exclusively from a ground water source (wells) known as an alluvial aquifer.   An alluvial aquifer is an area of water bearing sand and gravel typically found near lakes, streams and rivers; in our case, the Colorado River.  Bastrop began pumping from this source in the 1930's and continued until 1965.  We returned to this water supply in 1989 and continue to enjoy the high quality water found in the area.


The Texas Natural Resource Conservation Commission (TNRCC) has assessed the City of Bastrop's system and determined that the water is safe to drink.  The assessment was made by using data in tables shown below.  Since your water meets federal standards, there may not be any health-based benefits of purchasing bottled water of point of use devices.

The TNRCC will be reviewing all of Texas' drinking water sources. The source water assessment process will be completed in three years. It is important to protect your drinking water by protecting your water source.

The table below contains all of the federally regulated or monitored constituents which have been found in your drinking water. U. S. EPA requires water systems to test up to 97 constituents. None of the detected chemicals exceed the MCL for that chemical and no remedial action is required.

Unregulated Contaminants

Year Constituent Average of All Sampling Points Range of Detected Levels Reason for Monitoring
2002 Chloroform 1.925 ppb 1.2000 - 3.0000

Unregulated contaminant monitoring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants.
2002 Bromoform 6.025 ppb 4.1000 - 8.9000 Unregulated contaminant monitoring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants. 
2002 Bromodi-choloromethane 6.85 ppb 4.6000 - 9.6000 Unregulated contaminant monitoring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants. 
2002 Dibromochloro-methane 13.475 ppb 10.0000 - 17.1000 Unregulated contaminant monitoring helps EPA to determine where certain contaminants occur and whether it needs to regulate those contaminants. 

Total Coliform: Not detected.
Fecal Coliform: Not detected.

DEFINITIONS:

Maximum Contaminant Level (MCL) - The highest level of a contaminant in drinking water. MCLs are set close to the MCLGs as feasible
using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG) - The level of contaminant in drinking water below which there is not known or expected health risk.
MCLGs allow for a margin of safety.

Treatment Technique - A required process intended to reduce the level of a contaminant in drinking water.

Action Level - The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

ppm - parts per million; sometimes expressed as milligrams per liter.

ppb - parts per billion; sometimes expressed as micrograms per liter.

pCi/I - picocuries per liter ( a measure of radioactivity).
