Session Topics include:
- Lunchtime Talk: ARPA Presentation from Water Investment Division
Purpose and Objective: Update and review of ARPA and Revolving Loan funding including 3-Ac Stormwater, Lead Service Inventories, and other related funding topics.
- Padraic Monks – Water Investment Division Financial and Loan Programs Manager
- Topic #1: Case Study on Service Line (SL) Identification Approaches and Associated Costs
Purpose and Objective: USEPA’s Lead and Copper Rule Revisions require every community water system in the country to prepare an inventory of service line materials. The town of Bennington, VT is actively working to identify and replace every lead service line in its water system. Available records of service line materials are unreliable, and a stepwise approach has been developed and implemented to identify service line materials throughout the distribution system. This presentation will review the development of Bennington’s stepwise approach, evaluating the accuracies and costs for service line identification methods including records reviews; visual observations; fully flushed and sequential profile samples; and test excavations.
Presenter: Patrick Smart, PE – MSK Engineers
- Topic #2: High resolution characterization and the Discrete Fracture Network™ approach for improved CSM development and Remediation at two chlorinated solvent contaminated sites
Purpose and Objective: This presentation will include a summary of how high-resolution site characterization techniques are critical to developing conceptual site models and providing a sound basis for contaminated site management and remediation. The case studies will highlight two unique approaches to the remediation of Trichloroethene plumes based on the high-resolution characterization. One with an in-situ Chemical Oxidation system implementation and the other with a sustainable bio / phytoremediation remedy. The Rock Core Discrete Fracture Network™ (DFN™) characterization technology will be highlighted as a characterization approach with discussion on how it is being adapted for PFAS.
Presenter: Bradley Green, P.G. and Jessica Bulova, PMP – Sanborn Head and Associates
- Topic #3: Lower Welden Stormwater Treatment Facility
Purpose and Objective: Presentation will review the City of St. Albans’ Lower Welden Stormwater Facility and the complexities related to siting, designing and permitting a facility of this scale in an urban environment while meeting new 3-acre requirements for both the City owned land and nearby private 3-acre properties. This project was funded by an agreement LC-00A00394 awarded by the Environmental Protection Agency to the New England Interstate Water Pollution Control Commission in partnership with the Lake Champlain Basin Program. NEIWPCC manages LCBP’s personnel, contract, grant, and budget tasks and provides input on the program’s activities through a partnership with the LCBP Steering Committee.

- Topic #4: Topic #4: Vermont Green Schools Initiative, Three Acre Stormwater Design Projects
Purpose and Objective: Utilizing experience gained working with School representatives, DEC regulators, and the State’s private consultant administering Vermont’s Green School Initiative this presentation will provide background on the 3 acre component of the Stormwater Rule, OCE’s overall planning and design approach for 3 acre projects leading to a discussion on the effectiveness of the approach, challenges encountered, refinements and lessons learned as projects move to final design and permit submission.
