City gets aggressive in fighting Zebra mussels

Post Date:May 26, 2017
The City of Lewisville is taking an aggressive approach to combat Zebra mussels to maintain the safety and reliability of the water supply.

Zebra mussels are an invasive species of freshwater mussels that have been causing havoc with ecosystems in North America. Feeding on algae, the mussels colonize in mass creating blockages and causing damage to pipelines, waterways, and even water treatment plants.

The City has been working with a professional water engineering firm to study and develop strategies to protect the City’s water system. Beginning in June, the City will introduce a copper ion treatment into the water system at the Lewisville Lake intake pipes. Trace amounts of copper ion will penetrate and break down the biofilm, the accumulation of microorganisms on wet surfaces, on the pipe walls, which serves as an ideal place to attach and grow for Zebra mussel veligers (larva stage of Zebra mussels).

Copper ion treatment is considered more economical than other chemical treatments. It is a proven technology in naval and power generation plants in prohibiting biofilm in various water sources around the country. The use of copper ion has become a viable, cost-effective option at intake and transmission pipelines that provide water supply to drinking water treatment plants.

As part of the drinking water treatment process, the mussels, biofilm, and copper will be removed through normal water treatment processes. The City has developed a monitoring plan to evaluate copper dosage throughout the treatment process as required by the Texas Commission on Environmental Quality. Additionally, the City will begin increased lead and copper testing on water lines in resident’s homes as part of the monitoring plan. Currently, the City has been under “reduced monitoring” status which requires lead and copper testing on the water lines of 30 volunteer houses around the city every three years. As a precautionary measure, TCEQ has expanded that testing to 60 homes.

This increased testing requirement by the TCEQ does not mean there is an increase in lead/copper in residential houses. This additional testing is being done to ensure no increase in levels once the copper ion treatment begins.

Because 30 homes already are in the voluntary testing program, 30 more are needed. If a resident would like to volunteer, they must have a house built before 1986 because those homes are more likely to have lead pipes and fixtures. They could also have brass, copper plumbing and/or chrome-plated fixtures in their homes.

A third-party company running the program will send the resident a kit in the mail that includes some paperwork and a one-liter bottle. The resident will fill out the forms, follow the directions on how to collect the water sample, and then mail it back to a laboratory for lead and copper testing. There is no cost to the resident to return the sample. The resident will be given a website log-in where they can monitor the testing process of the water collected from their homes. The City also will receive notices of all results.

Please call the City of Lewisville Environmental Control Services Laboratory at 972.219.3545, or send an email to ECSLab@cityoflewisville.com if you meet the requirements and want to participate in the lead and copper sampling program.

Every year, the City of Lewisville publishes results of all water tests in the Water Quality Report. This report can be accessed online at the Water Quality Reports page on cityoflewisville.com. The report is created using the most recent U.S. Environmental Protection Agency and TCEQ test results. Lewisville’s water system is rated “Superior,” which is the highest rating from the TCEQ
