Local conditions

Environmental conditions in El Paso County

El Paso County sits at the foot of the Rockies, where rapid residential and commercial growth along the I-25 corridor meets a legacy of military installations, agricultural operations, and former light-industrial sites. That combination means environmental due diligence is not a formality—it is a practical step that protects transaction value and keeps construction schedules intact. Our firm provides Phase I and Phase II Environmental Site Assessments as well as construction-phase environmental support, dispatched to El Paso County from our Denver regional hub. Whether you are closing on a commercial parcel in Colorado Springs, breaking ground on a mixed-use development in Monument, or managing stormwater compliance on an active site, our team brings consistent documentation and field protocols that lenders, engineers, and regulators can act on. The laboratory operates under a documented quality system, and field technicians hold current ACI and NICET certifications where applicable to construction-phase work.

El Paso County's soils include expansive clays and fill materials in developed areas, conditions that can influence subsurface investigation planning during Phase II work and affect how environmental samples are collected and interpreted. Colorado's dry climate and seasonal temperature swings are also relevant to vapor intrusion evaluations, since low humidity and freeze-thaw cycling can affect how subsurface contaminants migrate toward occupied structures.

FAQ · El Paso County

Can radon be part of an environmental assessment for a commercial building in El Paso County?

Radon is not addressed under ASTM E1527-21 Phase I scope, but Colorado's Front Range—including El Paso County—is situated in EPA Radon Zone 1, indicating the highest potential. For commercial projects with occupied below-grade or slab-on-grade spaces, a standalone radon assessment can be scoped separately and is worth discussing with your lender or project engineer before closing.

How does the expansive soil character in El Paso County affect how you conduct a Phase II investigation?

Expansive clays common to parts of El Paso County can complicate borehole advancement and soil sampling. Field crews account for difficult drilling conditions when selecting equipment and sampling intervals. Sample collection and handling follow ASTM D4700 guidance for soil sampling, and the site-specific geology is noted in the work plan so the laboratory and reviewing engineer have full context for analytical results.

My project is near a former agricultural area in El Paso County. What contaminants should I be concerned about?

Former agricultural land may carry residual pesticides, herbicides, petroleum from equipment storage, and fertilizer constituents including nitrates. A Phase II scope for these sites typically includes soil and groundwater sampling analyzed for organochlorine pesticides per EPA Method 8081, petroleum hydrocarbons, and inorganic analytes. The specific analyte list is finalized based on historical use findings from the Phase I records review.
