Questions & Answers / Clarifications

This document provides responses to vendor questions regarding Solicitation 140P1426Q0031 for Groundwater Monitoring at Grand Teton National Park.

• Formaldehyde Analysis: Required only for the three Gros Ventre wells as listed in Table 3.
• Purge Water Disposal: For annual monitoring, purge water may be scattered on the environment. For Colter Bay Landfill monitoring, it can be disposed of at the Colter Bay Sewage System (43.901422°, -110.627404°). The COR will facilitate site access.
• Dedicated Bailers: No wells currently have dedicated bailers installed.
• Reporting Frequency: One report per year is required, inclusive of both spring and fall events. Spring sampling results should be provided when available, potentially in an Excel format similar to Attachment 6.
• IDW Disposal (Colter Bay Landfill): Liquid IDW and disposable sampling equipment can be disposed of at the Colter Bay Sewage System. The COR will facilitate access.
• IDW Disposal (Bi-annual Sampling): IDW for bi-annual sampling may be scattered on the environment, as background data does not suggest it is hazardous.
• Work Plan/HASP: A proposed methodology, including a work plan or Sampling and Analysis Plan, is required with the bid proposal, in addition to a Health and Safety Plan (HASP).
• Sampling Techniques: Standard sampling techniques, as described in the U.S. EPA manual RCRA Groundwater Monitoring Technical Enforcement Guidance Document (September 1986), are acceptable for all sites unless alternate methods are approved.
• Small Business Set-Aside: Confirmed as a small business set-aside with NAICS Code 541620 and a Small Business Size Standard of $19M.
• Recent Experience: Ongoing projects can be submitted if at least 50% complete.
• Laboratory Analysis: Included in the contractor's unit pricing.
• Report Format: Attached groundwater monitoring reports are representative of the expected format and detail for future reporting.

These clarifications provide specific details on waste disposal, sampling methods, reporting, and experience requirements. Offerors should ensure their proposals address these points. The solicitation is a small business set-aside under NAICS 541620.

Amendment / Modification

• Amendment 0001 to Solicitation #140P1426Q0031 clarifies that the requirement for "Annual Groundwater Sampling of Monitor Wells in Grand Teton National Park and the John D. Rockefeller Memorial Parkway" is a Total Small Business Set-Aside.

• This clarification corrects an error in the original solicitation (SF-18) which incorrectly stated that it was not a small business set-aside.

• The clarification pertains to the set-aside status of the requirement.

• This amendment does not appear to change the proposal deadlines or other submission requirements, but it is critical for small businesses to note the set-aside status for eligibility.

It notes that groundwater flow is generally south-southeasterly and identifies several constituents (1,2-dibromoethane, beryllium, iron, lead, manganese, and Total Dissolved Solids) detected at concentrations exceeding regulatory screening levels for drinking water. However, it clarifies that this groundwater is not used as a drinking water source, thus posing no imminent health risks.
• Introduction: Provides background on the contract with the National Park Service (NPS) and the sampling event, noting that the last sampling occurred in September 2022.
• Field Sampling and Analysis: Describes the procedures used for well site inspection, monitoring well gauging, and low-flow sampling methods, including stabilization criteria.
• Laboratory Analysis: Lists the parameters analyzed, including volatile organic compounds, TAL Metals, and general groundwater chemistry. It details sample collection, preservation, and handling specifications.
• Quality Assurance and Quality Control (QA/QC): Outlines the QA/QC samples collected (trip blanks, field duplicates, matrix spikes) and discusses findings related to potential cross-contamination and analytical precision.
• Data Presentation and Evaluation: Presents groundwater flow data and analytical results, highlighting constituents that exceeded quality standards. It also notes the historical detection of toluene, which was not detected in 2024.
• Statistical Evaluation: Analyzes groundwater data from 2006 to 2024 using EPA's ProUCL software to identify statistically significant differences in chemical concentrations between background and downgradient wells.
• Findings and Recommendations: Summarizes key findings, including groundwater elevation fluctuations, flow direction, and the detection of constituents above screening levels. WWC Engineering recommends continued monitoring of the landfill.

This report provides critical environmental data related to the Colter Bay Landfill. Bidders interested in environmental consulting, remediation, or monitoring services in the Grand Teton National Park area would find this data relevant for understanding site conditions, historical contamination, and regulatory compliance requirements.
