Local conditions
Environmental conditions in San Juan County
San Juan County sits at the heart of the San Juan Basin, one of the most prolific natural gas and coalbed methane producing regions in the American Southwest. Decades of energy extraction, pipeline infrastructure, and associated industrial activity mean that due diligence on land in this county carries real weight—whether you are financing a commercial pad site in Farmington, developing a logistics facility near Bloomfield, or breaking ground on infrastructure serving the regional energy sector. Residual contamination from hydrocarbons, produced water, or legacy industrial operations can stall transactions, delay permits, and expose buyers to long-term liability. Our environmental services team provides Phase I and Phase II Environmental Site Assessments, construction-phase soil and groundwater support, and regulatory coordination designed to give contractors, developers, and engineers a clear picture of site conditions before commitments are made. Coverage for San Juan County is dispatched through our Denver regional hub, with scheduling arranged in advance to fit project timelines.
San Juan County's subsurface is characterized by sedimentary geology common to the Colorado Plateau, with soils that can include silty and sandy alluvial deposits along river corridors and tighter formations at upland elevations; arid, high-desert conditions limit natural attenuation of certain contaminants and can complicate vapor intrusion assessments, making thorough site characterization especially important before construction begins.
FAQ · San Juan County
Does the history of oil and gas activity in the San Juan Basin affect how a Phase I ESA is scoped for a typical commercial site?
Yes. The density of historical and active energy operations in the San Juan Basin means that recognized environmental conditions (RECs) related to hydrocarbon releases, pipeline easements, and produced water disposal are common findings. The environmental professional conducting the assessment follows ASTM E1527-21, which requires evaluation of all reasonably ascertainable records, and a thorough review of state Oil Conservation Division databases is standard practice for sites in this county.
What New Mexico state agency receives Phase II findings, and does that affect how reports are formatted?
The New Mexico Environment Department (NMED) oversees voluntary and mandated site cleanup programs, including the Voluntary Remediation Program and the Petroleum Storage Tank Bureau. Phase II reports intended for regulatory submission are formatted to address NMED data quality and reporting requirements alongside ASTM E1903-19 guidance, so agency expectations are built into the work scope from the start rather than addressed after delivery.
How does the arid climate in San Juan County affect soil sampling and vapor intrusion evaluation during a Phase II?
Low annual precipitation and high evapotranspiration rates reduce natural flushing of shallow soils, which can concentrate certain contaminants near the surface. Conversely, dry conditions affect capillary rise and soil moisture assumptions used in vapor intrusion modeling. Sampling protocols follow ASTM E1903-19 and applicable EPA vapor intrusion guidance, with soil classification and moisture content documented to support site-specific modeling inputs.
