Request for Bids – Soil & Groundwater Sampling Mount Washington State Park – Summit Environmental Assessment Project #CAP2610

1. Clarification – Existing Groundwater Wells

This Addendum clarifies requirements in Section 4. Project.Specifications of the Request for Bids.

• Existing Groundwater Wells DNCR confirms that only one (1) existing well, located at the summit will be included in this investigation for groundwater sampling.

• Scope Adjustment

• No other existing wells are to be accessed, tested, or included in the sampling program. Only 1 existing well is to be tested.

• The requirement to install temporary monitoring wells remains unchanged unless otherwise modified by subsequent addenda.

• Bidders shall prepare pricing accordingly.

2. NHDES Project Manager:

• DNCR is coordinating with NHDES, and no NHDES project manager is assigned.

3. Drivers of the Investigation:

4. Existing Well Data / Groundwater Depth:

• DNCR has available well logs, construction details, and any known groundwater data for the existing wells on the summit.

• Clarification: Only one existing well is part of this project’s sampling scope. No other wells are planned for testing.

• DNCR is determining whether any historic analytical results exist for the single well included in the scope. Additional sampling of other water sources is not planned.

5. Temporary vs. Permanent Wells

• DNCR’s current intention is to test the existing well solely for investigative purposes. There is no active plan to convert them to permanent wells.

6. Analytical Suites

• Full suites (VOCs, SVOCs, PAHs, TPH, metals, PFAS) are anticipated; however, the number of samples requiring each suite will be specified to ensure consistent pricing.

7. Access Restrictions for Drilling Rigs

• Vehicle weight and size restrictions do apply on Mt. Washington Auto Road. DNCR will clarify allowable equipment types and whether a special access permit will be required. No permits have been required in the past, just coordination with the Mt.
