El Paso Metals Site Sampling, TX

Weston deployed innovative data management technology to expedite the collection of 12,000 samples from 2,025 private homes; by analyzing and collecting 1,200 samples in under ten days, Weston brought significant cost savings and efficiency to the project.

EPA Region 6 detected high levels of metals in soils near a copper smelter in El Paso, representing a potential imminent and substantial danger to human health. Weston coordinated closely with EPA under the Rapid Response contract to model the copper smelter stack emissions, identify a 3-mile radius of potential impact, and implement a four-phase sampling program to determine whether removal actions were warranted.

Weston deployed innovative data management technology to expedite the collection of 12,000 samples from 2,025 private homes. In only 9 days, Weston analyzed and collected 1,200 samples, saving EPA an estimated $150,000. Using a GIS database, we prioritized work and supported EPA in responding to individual public inquiries regarding property status. Our team analyzed daily samples within 8 to 12 hours to determine whether school property soil removal was required before children returned from summer break.

Weston performed oversight of the Emergency Rapid Response Services contractor; coordinated with federal, state, and local officials; and was acting liaison between EPA and over 2,000 El Paso homeowners and residents. Commercial, public, and undeveloped properties, and 2,025 private homes were sampled to determine surficial soil metals contamination (arsenic and lead). We also identified high-population traffic at risk areas.
