Local conditions
Environmental conditions in Merrimack County
Merrimack County's development landscape reflects New Hampshire's broader history: mill-era industrial sites along river corridors, agricultural land being converted for residential and commercial use, and a growing pipeline of mixed-use redevelopment in communities like Concord and Pembroke. Each of those project types carries environmental due-diligence requirements that, if handled late or incompletely, stall financing, trigger regulatory review, or surface liability after closing. Our firm provides Phase I and Phase II Environmental Site Assessments along with construction-phase environmental support—stormwater compliance documentation, soil management oversight, and underground utility and storage tank coordination—to keep transactions on schedule and projects moving through permitting. Coverage for Merrimack County is dispatched through our Boston, MA regional hub. Scheduling is project-based; contact us early in your timeline so we can align assessment and reporting deliverables with your closing, permitting, or construction milestones.
New Hampshire's glacially deposited soils—ranging from outwash sands and gravels to dense till—can complicate subsurface investigation planning, as depth to bedrock and groundwater elevation vary significantly across short distances in Merrimack County. The region's defined freeze-thaw season and spring wet conditions are practical considerations when scheduling Phase II field work or construction-phase soil sampling.
FAQ · Merrimack County
Does New Hampshire have state-specific requirements that go beyond the ASTM E1527-21 standard for a Phase I ESA?
ASTM E1527-21 sets the federal All Appropriate Inquiries baseline, but New Hampshire NHDES maintains its own regulatory database and brownfields guidance that an environmental professional must consult. Our Phase I reports incorporate NHDES file reviews and state hazardous waste site records alongside the standard federal and commercial database searches required by E1527-21.
Our site in Merrimack County was historically used for agriculture. What environmental concerns should we be looking for during due diligence?
Agricultural properties may have legacy pesticide and herbicide applications, buried fuel storage for farm equipment, and former orchard areas where arsenic-based pesticides were historically used in New England. A Phase I ESA will flag these recognized environmental conditions, and if warranted, a Phase II investigation under ASTM E1903-19 can include targeted soil sampling to characterize actual conditions before closing or construction.
How does New Hampshire's winter and spring wet season affect Phase II subsurface investigation scheduling in Merrimack County?
Frozen ground can prevent hand-auger and direct-push sampling and may require equipment mobilization delays. Spring snowmelt raises groundwater tables across much of the county, which can affect vapor intrusion assessments and soil sample interpretation. We factor seasonal conditions into sampling protocols and recommend scheduling Phase II fieldwork outside peak freeze or saturation windows when project timelines allow.
