Mitigating PFAS contamination in the United States: assessing the impact of California's legislation from 2018 to 2022 on drinking water quality.
Review in Journal of public health policy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study evaluates the impact of California's specific per- and polyfluoroalkyl substances (PFAS) legislation on perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) contamination levels in public drinking water. We conducted a comparative statistical analysis using data collected by the United States Environmental Protection Agency (US EPA) Unregulated Contaminant Monitoring Rules (UCMRs), specifically UCMR 3 and UCMR 5. To assess PFOA and PFOS levels in active public water systems during the pre-legislation period (2017) and the post-legislation period (2023) we applied Levene's test to assess differences in variances, followed by unpaired and Welch's t-tests to compare mean PFAS concentrations between the two time periods. We detected a significant decline in both PFOA and PFOS levels post-legislation, suggesting that robust state-level regulatory measures can effectively reduce PFAS contamination. Findings highlight the potential for California's comprehensive approach to serve as a model for national policy to mitigate PFAS exposure and protect public health.
