W&M has provided due diligence services, Leaking Petroleum Storage Tank (LPST) site assessments, Texas Risk Reduction Program (TRRP) site assessments and reporting, tank removal, remediation design/oversight, and obtained regulatory closure at mulitiple facilities for our client throughout Texas (as well as OK, KS, AR, and Jamaica). W&M’s work with our client was instrumental in obtaining regulatory closure of Service Operations Centers in the following locations: Fort Worth, Arlington, Dallas, Austin, Midland, Houston, Corpus Christi, Richardson, Longview, McKinney, San Antonio, Tomball, Huntsville, Midlothian, and Pittsburg.  

Our staff worked with Dallas County District #6 to address contaminated soil along Interstate IH-30 in Balch Springs, Texas. The subject property was adjacent to a gasoline service station and had been impacted with petroleum hydrocarbons. The impact had stopped development of a planned subdivision and specifically the utilities along the highway access road. W&M conducted Phase II sampling at the site, designed plans and specifications for modifications to the buried utilizes, and provided general consulting services to Dallas County to complete this project.

W&M has a long history of working with AT&T on a wide range of projects dating back to 1998. Our work with AT&T has included Phase I ESAs, Phase II Investigations, removal of PSTs, closure of LPSTs through the TCEQ PST program (reimbursable and non-reimbursable sites), site remediation, and use of soil vapor extraction (SVE) as a treatment method. W&M has successfully worked with AT&T to become one of their prime contractors in Texas and surrounding states.

W&M Brownfields assisted investors in the acquisition of a contaminated property in downtown Austin, through a limited liability corporation, at a discounted price. The property was a former gasoline service station that had the tanks removed while a petroleum hydrocarbon release had occurred but was not reported. W&M located financing and negotiated the sale and closure of the property for the investors. A tenant was located and the property was leased in order to provide income for the investors while regulatory closure is achieved. This property is not currently for sale.

W&M completed a thorough Site inspection that included plotting the exact location of all current and former oil and gas wells using a GPS. Field data was overlaid with Railroad Commission of Texas (RRC) well data to determine the accurate number of active, plugged, and abandoned wells at the Site. W&M identified eight main oil field areas during the Site reconnaissance. Based on Site conditions, W&M developed an environmental liability cost estimate.

W&M completed an assessment of the Site in the vicinity of the Olin Gathering System located near Deadwood, Texas. A release from the gas gathering lines had impacted surface soil and associated drainage area. W&M addressed the impacted soil by bio-treatment and removal of the floating free product. Total petroleum hydrocarbons (TPH) were treated from over 5,000 parts per million (ppm) to less than 400 ppm. As a result of our response actions, no additional remedial actions were required for this Site.

W&M has worked on a wide range of projects for a nationally respected law firm and their clients. This work has included real estate due diligence for mergers and aquisitions and regulatory compliance projects. Specific projects have included Phase I ESAs, Phase II Investigations, addressing enforcement issues with the TCEQ, and remediation projects. Working with this law firm required attention to detail and expertise with the fate and transport of potential chemicals of concern in the soil and groundwater.
