#9 of 25 ยท Best Water Quality Reports in America 2026SilverPDF report

WSSC Water

Laurel, Maryland

WSSC reads like a corporate magazine โ€” polished spreads, water-drop stat callouts, and a custom map of its two river sources and where they blend. It has tested for PFAS voluntarily since 2020, monthly since 2022, and lets you compare its two plants side by side. Design flourishes occasionally fight readability, and there is no web-native version, which keeps it in the silver tier.

Scored edition: 2024 Water Quality Report: Ensuring Safe Water for Thriving Communities (2024 data). WSSC Water has since published its 2025 Water Quality Report: Excellence Expanded, Safeguarding Every Sip (2025 data), which was not scored.

  • Corrected September 13, 2026: Each scorecard now names and links the exact report edition we scored, and notes any newer edition the utility has published. Some report links had pointed to pages that have since moved on to a newer edition.
  • Corrected September 13, 2026: The scorecard described a map of three water sources and voluntary monthly PFAS monitoring since 2020. The map shows two river sources and the area where they blend, and the report describes quarterly PFAS testing from 2020, monthly from September 2022.

Plain-language clarity25% of score

4/5+0.3 vs avg

Generally readable with clear stat callouts, though some body text is wrapped along diagonal shapes, which works against it.

A 5/5 looks like: Every term is translated, units are made tangible (e.g. an Olympic-pool analogy), and each section opens with what it means for you.

Contaminant transparency25% of score

4/5โ‰ˆ cohort avg

Voluntary PFAS testing since 2020, monthly since September 2022, with detected values shown against the limits, plus dual-plant (Patuxent vs Potomac) comparison tables.

A 5/5 looks like: PFAS, lead and any exceedances are shown with real values against the limits, and problems are disclosed plainly rather than buried.

Information design20% of score

4/5+0.9 vs avg

Corporate-magazine spreads with water-drop stat callouts and a custom service map of Potomac, Patuxent and blended water; strong, if occasionally style over substance.
