2018 Annual Drinking Water Quality Report

(Consumer Confidence Report)


Phone Number: (409) 385-2863

PWS ID Number: TX1000002


Water Quality Report for the period of January 1 to December 31, 2018

This report is intended to provide you with important information about your drinking water and the efforts made by the water system to provide safe drinking water.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants.  The presence of contaminants does not necessarily indicate that water poses a health risk.  More information about contaminants and potential health effects can be obtained by calling the EPAs Safe Drinking Water Hotline at: (800) 426-4791

Information on Sources of Water

The City of Silsbee's source of water is ground water pumped by three deep wells from the Chicot Aquifer and the deeper Evangeline Aquifer.  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 pick up substances resulting from the presence of animals or from human activity.

Contaminants that may be present in source water include:

-Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

-Inorganic contaminants, such as salts and metals, which can be naturally- occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

-Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses.

-Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems.

-Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.

Information about Secondary Contaminants

In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems.  FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.  Contaminants may be found (such as calcium, sodium, or iron) in drinking water and may cause taste, color, and odor problems.  These types of problems are not necessarily causes for health concerns.  For more information on taste, odor, or color of drinking water, please contact the system's business office.

Special Notice

You may be more vulnerable than the general population to certain microbial contaminants, such Cryptosporidium, in drinking water.  Infants, some elderly, or Immuno-compromised persons such as those undergoing chemotherapy for cancer; persons who have undergone organ transplants; those who are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders, can be particularly at risk from infections.  You should seek advice about drinking water from your physician or health care providers.  Additional guidelines on appropriate means to lessen the risk of infection by Cryptosporidium are available from the Safe Drinking Water Hotline (800-426-4791).

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children.  Lead in drinking water is primarily from materials and components associated with service lines and home plumbing.  We are responsible for providing high quality drinking water, but we cannot control the variety of materials used in plumbing components.  When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking.  If you are concerned about lead in your water, you may wish to have your water tested.  Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at

Information about Source Water Assessments

A Source Water Susceptibility Assessment for your drinking water source(s) is currently being updated by the Texas Commission on Environmental Quality.  This information describes the susceptibility and types of constituents that may come into contact with your drinking water source based on human activities and natural conditions.  The information contained in the assessment allows us to focus source water protection strategies.

For more information about your source(s) of water, please refer to the Source Water Assessment Viewer available at the following URL:

Further details about sources and source water assessments are available in Drinking Water Watch at the following URL:

Source Water Assessment Protection

The TCEQ completed an assessment of your source water and results indicate that some of our 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 Confidence Report.  For more information on source water assessments and protection efforts at our system, contact Joe Moreno at (409) 385-3535.


Water Quality Test Results


Level 1 Assessment: A Level 1 Assessment is a study of the water system to identify potential and determine (if possible) why total coliform bacteria have been in out water system

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

Level 2 Assessment: A Level 2 Assessment is a very detailed study of the water system to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions.

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 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.

Maximum Residual Disinfectant Level:  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.



MFL: Million fibers per liter (a measure of asbestos

Na: Not applicable

Mrem:Millirems per year (a measure of radiation absorbed by the body)

NTU: nephelometric turbidity units (a measure of turbidity)

Treatment Technique or TT: A required process intended to reduce the level of a contaminant in drinking water

Ppt: Part per trillion, or nanograms per liter (ng/L)

Ppq: Parts per quadrillion, or pictogramsper liter (pg/L)

Avg: Regulatory compliance with some MCLs is based on running annual average of monthly samples.

ppm: Milligrams per liter or parts per million - or one ounce in 7,350 gallons of water.

Action Level Goal (ALG): The level of a contaminant in drinking water below which there is no known or expected risk to health.  ALGs allow for a margin of safety.

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