Dissolved Organic Carbon Source Impact on Perfluoroalkyl Substances Removal from Stormwater Using Activated Carbon and Ion Exchange Resin.
Article in Environmental science & technology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The capture and recharge of urban stormwater can augment water supplies in dry regions. To safely use urban runoff, it is necessary to remove harmful trace organic contaminants, especially perfluoroalkyl substances (PFASs). This study assesses the removal of six PFASs from synthetic stormwater with dissolved organic carbon (DOC) derived from straw and compost, which are representative materials observed in stormwater catch basins. Activated carbon (AC) and ion-exchange resin (IX) alone or in tandem are used to assess the impact of DOC on the sorbent performance and lifetime. PFAS breakthrough profiles in column studies are used to model contaminant removal via a 1-D intraparticle pore diffusion model, which is then used to predict contaminant removal under varying environmental conditions. Experimental results show PFAS removal is worst when biodegradable straw DOC is present, indicating larger kinetic limitations to sorption than nonbiodegradable compost DOC. The use of AC and IX in combination shows additive improvements over using the sorbents individually. Modeled parameters from replicate tests show consistency in the predicted breakthrough. With 3 mg/L compost DOC and 80 cm/h face velocity, models show that 50-100 cm AC followed by 12.5-50 cm IX provides long-term PFAS removal, ca. 10 years or 90,000 empty bed volumes.
