LNVA Canal Water Quality Data
Lower Neches Valley Authority collects and analyzes canal water samples daily to provide its industrial and municipal customers with current water quality data. The data enable our customers to prepare for any changes in water quality directly affecting their water treatment processes, allowing them to prepare an adequate supply of chemicals to maintain the highest level of quality processed water. Each of our customers need specific information relative to their applications. For example, municipal water treatment plants need data on alkalinity, turbidity and pH, while industrial users are concerned about water hardness to determine if scaling would pose a problem. The following is an average, minimum and maximum value for each parameter.
