Explore the Conference (Home – NEWWA)
Weston & Sampson presents at the 2025 New England Water Works Association (NEWWA) Annual Conference, happening September 21–24 at the Samoset Resort in Rockport, Maine. This premier event brings together water industry leaders, utilities, regulators, and engineers to collaborate on advancing safe, sustainable, and resilient water systems.
Weston & Sampson’s team will be sharing expertise on PFAS remediation, stormwater and wastewater management, asset management, and climate-resilient water infrastructure. We look forward to connecting with industry peers and working together to protect New England’s most vital resource—clean water.

Don’t Empty the Tank: Elevated Storage Modifications in Charlotte, NC
Lancaster County Water & Sewer District serves a high-growth area outside Charlotte, NC. LCWSD has numerous pressure zones within their system, requiring extensive pumping, valving and segmentation. LCWSD and Weston & Sampson are completing a project to merge two densely populated pressure zones by lowering a 1-million-gallon elevated storage tank. This presentation will demonstrate how extensive planning, hydraulic modeling, old fashioned legwork and design expertise combined to improve operational efficiency and provide redundancy for a rapidly growing water system.

The True Cost of Quality: Ensuring PFAS Data Accuracy for Informed Decision-Making
Proactive quality control prevents costly issues associated with addressing data quality issues reactively and aligns with the Cost of Quality framework. This framework was originally developed for manufacturing, however, it can also be applied to PFAS analysis, where data accuracy impacts compliance, treatment, remediation, and litigation. High-quality PFAS data is essential to mitigate risks and avoid costly errors. Investing proactively in data quality
enhances data reliability, minimizes errors, and strengthens confidence in PFAS data needed to support decision-making.

A Toolbox Approach for MDBP Rules Compliance: An Enhanced Distribution Monitoring Case Study
The U.S.EPA is reviewing the microbial and disinfection byproducts rules as part of its six-year regulation review. This presentation provides a case study encouraging EPA to allow a “toolbox” of options meeting the intent of the rule of providing safe drinking water at lower chlorine residuals than the proposed minimum numerical values. One potential toolbox item is enhanced monitoring of the distribution system that would allow lower but sufficient levels of secondary disinfectant to keep the distribution system biologically stable.

One Well, Two Tests, and a Collaborative Path Forward: Lessons from Littleton’s Source Approval Journey
Presenters
KEVIN MacKINNON, PG, PH, Senior Technical Leader, Weston & Sampson, Portsmouth, NH,
COREY GODFREY, Deputy District Manager, Water Supply District of Acton, Acton, MA, and
MATT SILVERMAN, Water & Sewer Superintendent, Littleton Electric Light & Water Department, Littleton, MA
Eleven public wells in Boxborough, Massachusetts, were impacted by PFAS and road salt, prompting a partnership with Littleton to develop a new groundwater source. The project quickly became complex primarily due to endangered species habitat, resulting in two pumping tests and layered permitting. Ultimately, strong agency collaboration and timely funding—from MassDOT’s Salt Remediation Program and the Drinking Water State
Revolving Fund—made the project a success. This presentation shares lessons learned and strategies to streamline permitting while protecting vital water resources.
