Clean Up Work on Chemical Spill in the Creek Behind Town Hall Begins Today

On Thursday, April 30, Town staff noticed a discoloration of the water in the creek behind Town Hall. Staff determined that material being used for soil stabilization related to the construction project at Prestonwood Shopping Center permeated a storm drain and migrated into the creek. The construction company, Dallas-based Beck Group, has contracted with Cotton Remediation to manage the clean-up efforts. 

The remediation company will be using an onsite, multi-stage filtration system to filter out the pollutants. The Cotton team will be using tanker trucks to siphon water from Winnwood Creek. This water will be mixed with clean water and re-introduce behind Town Hall to help with the filtration process. They will also be pressure washing rocks and other hard services as part of the clean-up efforts.

Work on the project began today and crews will be working from 8am – 7pm on Saturday and Sunday. We expect this process to be completed by the middle of next week, including water quality testing. Texas Commission on Environmental Quality (TCEQ) has approved the plan and will inspect the work when completed.

Even though there is not a public health concern, we still ask that residents and their pets avoid the creek area until the cleanup effort has been concluded.

After further review of the situation, it appears that the soil stabilization material migrated into the creek through an undetectable fissure in the ground. The team at Beck has responded quickly and professionally and we appreciate their efforts to resolve the situation to Addison’s high standards.
Thank you for your patience with this disruption.
