In what amounts to an almost anticlimactic confirmation of what was already established, the City of San Antonio announced Friday afternoon that third-party testing of soil removed from the Henry B. Gonzalez Convention Center expansion site and moved to city land near the San Antonio Food Bank proves the soil is safe and uncontaminated.
Weston Solutions is the latest environmental firm to give the soil a clean bill of health after Metropolitan Health District hired the firm to confirm results reported by Raba Kistner in February after the initial tests performed by Geo Strata Environmental led to a report that suggested the soil was contaminated, an assertion contained in the report's narrative that contradicted the chemical analysis contained in the same report.
"Weston's results confirm the data from the two initial environmental reports that indicated the soil is safe for residential use and was appropriately reused on a commercial property," the City press release stated. "Data from Weston's tests showed metals below or within TCEQ's residential standards. The data also shows that the low levels of metals do not transfer through water, including groundwater and storm water runoff."
Weston's environmental analysis included 48 soil borings over the approximately 48-acre commercial site, according to the release.
Here is Weston's executive summary.
