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 http://www.epa.gov/safewater/lead.

Turbidity is a measurement of the cloudiness of the water caused by suspended particles. We monitor it because it is a good indicator of water
quality and the effectiveness of our filtration.

Water Loss
Water loss and accountability is reported annually to the Texas Water Development Board. Water loss is based on the amount of water
metered for delivery exiting the Water Treatment Plant less the amount of water accounted for as metered to the customers throughout the
system. Numerous factors account for the ‘loss’ of water including line breaks, filter backwash, weeping mains, theft, water quality flushing,
and meter inaccuracy.

Additional Information – City of Odessa Water Service Line Inventory
The City currently has a link for you to search by entering your address to check the current status of your service line. Lead Service Line
Dashboard (arcgis.com)
Keep in mind the inventory is still ongoing and not all service lines have been identified. You will notice one of four types of service line
identifications, lead, non-lead, galvanized requiring replacement (GRR) or lead status unknown. If your address is identified as lead or GRR,
those lines will need to be replaced. If your service line is identified as unknown there can be several reasons, the inspection has not been done
in your area or access was not possible at the time. If your address shows “Service Line Unknown”, there is a possibility that some or all of your
line could be made of lead or galvanized materials.
Important Reminder: Any house built after 1988 will not contain lead, as lead pipes were banned in Texas starting July 1, 1988.
Visit the website to check your address and ensure the safety of your water service. As we continue to work on identifying all water service lines
within our City we will be updating the link above. You will also have access to any frequently asked questions and updates in the city utilities

About the Tables Contained In This Report. The tables in this report list all of the federally regulated or monitored
constituents, which have been found in Odessa’s water. The EPA requires testing of up to 97 constituents. The
concentrations (MCL and MCLG) of these standards are set by the EPA based on the potential health effects of the
regulated constituent in the public water supply. The data presented in the report is from the most recent testing done in
accordance with regulations. The following abbreviations/definitions are used in the tables:
Action level – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a
water system must follow
Action Level Goal (ALG) – The level of a contaminant in drinking water below which there is no know or expected risk to
health. ALGs allow for a margin of safety.
Avg – Regulatory compliance with some MCLs are based on running annual average of monthly samples.
Level 1 Assessment – a Level 1 assessment is a study of the water system to identify potential problems and determine (if
possible) why total coliform bacteria have been found in our water system.
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 occasion.
MFL – million fibers per liter (a measure of asbestos)
Mrem – millirems per year (a measure of radiation absorbed by the body
NTU - Nephelometric Turbidity Units (a measure of turbidity)
ppb - parts per billion, or micrograms per liter (µg/L).
pCi/L - picocuries per liter (a measure of radioactivity).
ppt – parts per trillion, or nanograms per liter.
ppm - parts per million, or milligrams per liter (mg/L)
ppq – parts per quadrillion, or pictograms per liter
na – not applicable
Treatment Technique or TT – A required process intended to reduce the level of a contaminant in drinking water.
Maximum Contaminant Level Goal (MCLG) - The level of a contaminant in drinking water below which there is no
known or expected health risk to health. MCLG’s allow for a margin of safety.
Maximum Contaminant Level (MCL) - The highest level of a containment that is allowed in drinking water. MCL’s are
set as close to the MCLG as feasible using the best available treatment technology.
Maximum Residual Disinfectant Level Goal (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
contamination.
Maximum Residual Disinfectant Level (MRDL) – The highest level of disinfectant allowed in drinking water. There is
convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
