Laguna Madre Water District has been recognized as a Superior Water system for many years by TCEQ. Our Water Quality has been excellent, especially with our new micro-filtration system installed in 2014. Texas Drinking Water Watch maintains current information on Public Water Supply Systems, including our Water District. You may access the database at and enter our Water System No. TX0310005 for more information. Taste, color, or odor problems are not necessarily causes for health concerns.

Laguna Madre Water District is a public water system using surface water and conventional filtration and/or microfiltration. Treatment processes, personnel, and monitoring requirements are in place to meet the following requirements established by the Environmental Protection Agency and Texas Commission on Environmental Quality (TCEQ):

·         Pathogen control by removal/inactivation of viruses, Giardia lamblia, and Cryptosporidium,

·         Maintain residual disinfection throughout the water distribution system,

·         Exceed turbidity performance standards,

o   Turbidity is the measure of relative clarity of a liquid, an optical characteristic of water and an expression of the amount of light that is scattered by material in the water when a light is shined through the water sample. Material that causes water to be turbid include clay, silt, finely divided inorganic and organic matter, algae, soluble colored organic compounds, and plankton and other microscopic organisms. Turbidity monitoring demonstrates removal of these particles from our drinking water.

·         Cover finished reservoirs / water storage facilities,

·         Operate by Qualified, Licensed Personnel as specified by Texas Commission on Environmental Quality,

·         Demonstrate optimal corrosion control to protect public health by minimizing lead and copper levels in drinking water, and

·         Disinfection profiling to improve public health protection by reducing exposure to disinfection byproducts and bacteriological coliform and contaminants.
