About this file
This is an Addendum to a Request for Bids issued by the New Hampshire Department of Natural and Cultural Resources (DNCR) for soil and groundwater contamination sampling services at Mount Washington State Park. The addendum addresses contractor inquiries regarding project #CAP2610 and clarifies key project requirements and procedures. Contractors are responsible for proposing specific soil boring and temporary groundwater well locations based on historical data provided by DNCR and site conditions within their Sampling & Analysis Plan (SAP) submittal following Notice to Proceed. The fieldwork sampling window is June 1 through July 31, 2026, with work restricted to 7:00 A.M. to 4:30 P.M., Monday through Friday unless pre-approved. Contractors must demonstrate familiarity with Mount Washington State Park's rugged, steep, high-elevation terrain (4,600 feet and above) and its associated seasonal weather challenges, and early site visits are strongly recommended to assess access logistics, staging areas, and safety protocols. The Final EPA Region 1-compliant Quality Assurance Project Plan (QAPP) must be submitted within 30 days of Notice to Proceed (due by June 30, 2026), and all contractors must comply with NHDES Environmental Ordinance 600/610 and EPA Region 1 QA/R-5 safety standards. The contractor must include analyses for PFAS (EPA Method 1633), volatile organic compounds, semi-volatile organic compounds, polycyclic aromatic hydrocarbons, total petroleum hydrocarbons, and metals, with laboratory selection remaining at the contractor's discretion provided the chosen laboratory meets EPA Method 1633 requirements and regulatory standards.
The addendum confirms that the RFB does not predetermine the exact number and locations of soil borings and groundwater wells, nor does it reference existing environmental reports; however, DNCR will provide historical data regarding known contamination sites to the winning bidder, with most documented contamination occurring prior to DNCR's property ownership. Contractors are expected to conduct independent research on publicly available historical site documents to appropriately develop SAP locations. The contractor must deliver a Data Usability Summary Report (DUSR) and comprehensive draft and final reports including figures, tables, boring logs, well construction details, laboratory reports, and electronic data deliverables in formats compliant with EPA Region 1 QAPP and NHDES Environmental Ordinance requirements; however, the RFB does not prescribe specific templates. No specific template is mandated for DUSR and electronic data deliverable formats, but contractors should propose industry-standard formats aligned with NHDES and EPA Region 1 requirements, with clarifications available through the bid questions deadline of May 13, 2026. The addendum does not disclose pricing information, set-asides, incumbent contractors, or specific funding amounts or sources.

DNCR Responses to posed questions regarding project #CAP2610.
MWSP_SGS_RFB04-22-26-(002) dated April 22, 2026.
1. Soil Borings & Temporary Groundwater Wells
• The exact number and locations of soil borings and temporary groundwater wells are not predefined in the RFB. These will be identified and detailed as part of the contractor’s Sampling & Analysis Plan (SAP) submitted after Notice to Proceed.
Contractors are expected to propose specific locations based on historical data provided by DNCR, site conditions and project objectives within your SAP submittal.
2. Site-Specific Access, Safety, Seasonal Considerations
During the sampling window June 1 – July 31, 2026, note the following:
• Terrain at Mount Washington State Park may be rugged, steep, and exposed at high elevation (4,600 ft+), with potential for sudden weather shifts. The RFB emphasizes contractor site familiarity prior to bidding.
• There are no specific restrictions or seasonal site closures mentioned, but seasonal weather (e.g. wind, fog, precipitation) may impose field constraints.
• Contractors must show they can meet NHDES Env-Or 600/610 and EPA Region-1 QAPP/QA-R5 safety standards.
Early site visits are strongly recommended to assess access logistics, staging areas, safety protocols, and seasonal challenges.
3. Availability of Historical Data / Prior Assessment Reports
• The RFB does not reference any existing environmental reports or historical data, but this information will be provided by DNCR to the winning bidder. There are a few known sites that have records of previous contamination and will be mapped out for the winning bidder.
• Independent review of any public information to propose SAP locations appropriately is recommended, most of the contamination occurred prior to DNCR owning the property.
Unless posted in addenda, no internal DNCR data are guaranteed to be available—independent research on historical site documents will be needed prior to SAP development.
4. QAPP & EPA Approval
• The RFB mandates development of a full EPA Region-1-compliant QAPP to accompany the SAP.
• It requires submission of the Final QAPP within 30 days of NTP (due by June 30, 2026)
• While Region-1 QAPP compliance is required, there is no explicit statement regarding EPA’s direct approval before field work. Nonetheless, meeting all EPA QA/R-5 requirements is mandatory
• Given this timeline, anticipate review cycles and potential revisions; EPA or NHDES may require approval before field mobilization.
5. Laboratory Selection for PFAS & Other Analytes
• Laboratory analyses must include PFAS (EPA Method 1633), VOCs, SVOCs, PAHs, TPH, and metals.
• The RFB does not specify any required/preferred laboratory—selection is at the contractor’s discretion, if the chosen lab can analyze PFAS via EPA 1633 and meet regulatory standards.
Choosing a lab qualified in Method 1633A (latest December 2024 version) with demonstrated QA capabilities under Region 1 criteria would be advisable.
6. Data Usability Summary Report (DUSR) & EDD Format/Template Requirements
• The contractor must provide a Data Usability Summary Report (DUSR) and both draft and final reports including figures, tables, logs, well construction details, lab reports, and electronic data deliverables (EDD).
• The RFB does not prescribe a specific template, but compliance with EPA Region-1 QAPP and NHDES Env-Or requirements is expected—implying use of industry-standard formats for DUSR and EDD.
Contractors should propose formats that align with NHDES/EPA Region 1 standard submittals; if needed, clarification can be requested via the bid questions deadline (May 13) to ensure compliance.
