Key Points

To determine whether perfluorooctane sulfonate (PFOS) concentrations in surface water provide an independent and reliable predictor of PFOS bioaccumulation in fish across diverse aquatic ecosystems.
Assessed chemical concentrations of PFOS in surface water across contrasting aquatic environments.
Quantified corresponding PFOS bioaccumulation levels in wild fish tissues residing within those ecosystems.
Analyzed the predictive relationship between environmental water exposure and internal fish contamination.
Surface water PFOS levels directly and independently predicted tissue concentrations in fish across all sampled habitats.
The predictive capacity of surface water concentrations remained robust despite environmental contrasts between the studied aquatic ecosystems.
