Water Loss
In the water loss audit submitted to the Texas Water Development Board for the time period of Jan-Dec 2024, our system lost an estimated 330,730,841 gallons of water. If you have any questions about the water loss audit, please call Mr. Manuel Ponce, Ms. Aryzbeth Saldana, or Mr. Jesse Trejo during normal business hours (8:00 AM to 4:00 PM) Monday through Friday at 956-402-4302.
Milligram per liter (mg/l)=part per million (ppm): one ppm is about the same as one drop of soda in 35 quarts.
Microgram per liter (ug/l)=part per billion (ppb): is 1000 times less than ppm or one drop of soda in 35,000 quarts. pCi/l: Picocuries per liters-units of measure for radioactive substances.
Maximum Contaminants Level (MCL)-the highest level of contaminants in drinking water.
Maximum Contaminants Level Goal (MCLG)-the level of contaminants in drinking water below which there is no known or expected health risk; MCLG allows for a margin of safety.
Action Level-the concentration of a contaminant; which if exceeded, triggers treatment or other requirements, which a water system must follow.
NTU-Nephelometric Turbidity Units are units of measures for turbidity, such as miles measures distance. Turbidity has no health effects. However, turbidity can interfere with disinfecting and provide a medium for microbial growth. Turbidity may indicate the presence of disease causing organisms, including bacteria, viruses and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches. Turbidity is suspended materials that cause water to become cloudy.
