Sources of Drinking Water |
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pickup substances resulting from the presence of animals or from human activity.
|
Information about Source Water Assessments |
The TCEQ completed an assessment of your source water and results indicate that some of your sources are susceptible to certain contaminants. The sampling requirements for your water system are based on this susceptibility and previous sample data. Any detections of these contaminants may be found in this Consumer Confident Report. For more information on source water assessments and protection efforts at our system, contact Terry Tuttle, System Manager, High Gabriel WSC, (512) 259-3888. |
For more information about your sources of water, please refer to the Source Water Assessment Viewer available at the following URL: http://tceq.state.tx.us/drinkingwater/SWAP/index_swa.html

High Gabriel WSC obtains its water from the Trinity Aquifer, via wells located in the High Gabriel Estates subdivision, located two miles north of the city of Leander in Williamson County, Texas. |

Water Quality Test Results |
Definitions: |
The following tables contain scientific terms and measures, some of which may require explanation. |
Avg: |
Regulatory compliance with some MCLs are based on running annual average of monthly samples. |
Maximum Contaminant Level or MCL: |
The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. |
Maximum Contaminant Level Goal or MCLG: |
The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. |
Maximum residual disinfectant level or MRDL: |
The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. |
Maximum residual disinfectant level goal or MRDLG: |
The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. |
