W&M Closes Industrial Wastewater Releases at Central Texas Facility

Client: Jewelry Manufacturer
Location: Central Texas
Project: Soil Removal Response Action

Project Description

W&M completed a soil removal Response Action for two wastewater sumps at a jewelry manufacturing facility that were found to have elevated levels of arsenic, cadmium, copper and/or silver.

Project Details

During affected property assessment activities, surface soil at two Areas of Concern and were found to contain metals (arsenic, cadmium, copper, and/or silver) at concentrations exceeding the critical protective concentration level (PCL) for residential use.  Because of building renovation plans at the Facility, the Client opted to proceed with a soil Response Action, via a Self-Implementation Notice (SIN), prior to submittal of the Affected Property Assessment Report (APAR).  With a TCEQ-approved Class 3 groundwater designation, critical PCLs for the metals of concern were established as equal to the Texas Risk Reduction Program (TRRP) Tier 1 residential total soil combined (TotSoilComb) PCLs for a 0.5-acre source area.

W&M Solutions

The soil Response Action was initiated in August 2018 and completed in October 2018.  Affected surface soil was removed by excavation, profiled, and disposed at a nearby landfill.  Soil confirmation samples were collected for laboratory analysis, and additional over-excavation was conducted to fully remove the affected soil.  The APAR for the operational portion of the Facility was submitted in November 2018 and approved by the Texas Commission on Environmental Quality (TCEQ) in January 2019. Following a review of the Response Action Completion Report, the TCEQ issued a “no further action” letter in April 2019.
