About this file
This is an addendum to a Request for Bids issued by the State of New Hampshire for soil and groundwater sampling services at Mt. Washington State Park. Addendum 1, dated July 9, 2026, clarifies the requirements and procedures for managing purge water generated during temporary well purging activities associated with project CAP 2610. The addendum specifies that bidders must account for purge-water handling and disposal costs in their proposals using an estimated volume range of 100 to 300 gallons. Actual purge-water volumes will be determined during field operations, and contract pricing may be adjusted accordingly upon confirmation of actual quantities.
The addendum establishes two pathways for purge-water management based on contaminant levels: purge water meeting all New Hampshire Ambient Groundwater Quality Standards may be discharged on-site in accordance with state groundwater discharge regulations, while purge water exceeding these standards must be collected, containerized, transported off-site, characterized, and disposed of at a licensed treatment or disposal facility. Bidders are instructed to include all purge-water handling, disposal, and related costs in their bids using the placeholder volume range provided, with final invoicing subject to adjustment once actual field measurements are completed.

Addendum 1 – Clarification of Temporary Well Purging Water Management for CAP 2610 Mt. Washington State Park Soil & Groundwater Sampling.
Date: 7/9/2026
This document clarifies that temporary well purging water may be discharged on-site provided it meets all applicable New Hampshire Ambient Groundwater Quality Standards as governed under the Groundwater Discharge Program.
Purge-Water Management Bidders shall note the following requirements regarding management of purge water generated during temporary well purging:
• Purge water that contains contaminants exceeding Ambient Groundwater Quality Standards must be collected, containerized, transported off-site, characterized, and disposed of at a licensed treatment or disposal facility.
• If purge water meets all Ambient Groundwater Quality Standards, temporary on-site discharge is permissible in accordance with New Hampshire groundwater discharge regulations.
Estimated Purge-Water Volumes Because static water levels in the wells are not yet available, bidders shall assume an estimated purge-water range of 100–300 gallons for bidding purposes. Actual volumes will be confirmed in the field, and contract pricing may be adjusted accordingly.
Instructions for Bidders
• Bidders shall include all purge-water handling, disposal, and related costs using the placeholder volume range provided. Final invoicing may be adjusted once actual purge-water volumes are measured during field operations.
