In 2010 Directed Technologies Drilling, Inc. (DTD) installed horizontal remediation wells beneath county offices in Sante Fe, New Mexico. The project garnered design engineer Daniel B. Stephens & Associates, Inc. (DBS&A) an Engineering Excellence Award (EEA) from the American Council of Engineering Companies New Mexico (ACED NM). The award is for State Lead Remediation Services performed at the Santa Fe County Judicial Complex (SFCJC) in historic, downtown Santa Fe. Awarded annually, ACEC NM EEA’s recognize engineering firms for project that demonstrate a high degree of achievement, value, and ingenuity. Projects are rated on the basis of: uniqueness and originality; future value to the engineering profession and perception by the public; social, economic, and sustainable development considerations; complexity; and successful fulfillment of client/owner’s needs.*
Key features of the treatment systems included two horizontal soil vapor extraction wells and one horizontal hot-air injection well capable of delivering 400-degree-Fahrenheit air to the subsurface for thermally enhanced volatilization of contaminants. Since the plume extends beyond the site, the state of New Mexico will continue to operate two soil vapor extraction systems on adjoining properties. As of April 2011, more than 16,000 gallons of gasoline have been removed and treated by the systems designed by DBS&A.
