- This letter is in response to the comments of Prof. Tianming Huang on ¿Tracking nitrate and sulfate sources in groundwater of an urbanized valley using a multi-tracer approach combined with a Bayesian isotope mixing model¿ (Torres-Martínez et al., 2020). We appreciate Prof. Huang's insightful comments, his interest in our work, and his thorough analysis. We also acknowledge his constructive feedback and, upon reflection, would like to provide some clarification. The overall analysis and conclusions of the study remain unaffected. © 2025
