1. MCWD Is Expanding PFAS Monitoring and Developing a Microplastics Sampling Program The district plans to expand PFAS sampling beyond source wells into the distribution system and establish microplastics sampling at source wells and in the system. Staff reported no PFAS from district source wells. A citizen-science study raised public questions, and the additional sampling is intended to build a dataset that can help the district assess outside findings. Staff said it could not verify how or when those samples were collected. Staff described the distribution-system PFAS work as additional to its state-required source-well testing; they did not identify a state microplastics testing requirement.
