Baseflow and Stormflow Zinc Loads in a Small Agricultural River Catchment Influenced by an Industrial Area
Round 1
Reviewer 1 Report
This manuscript investigates a case study of the baseflow and stormflow Zinc loads in a small agricultural river catchment influenced by an industrial area. It basically satisfies the scope of the journal Water. As learned from the manuscript, it is well organized and written. I would like to recommend a minor revision as there are seveal issues to be further addressed:
- The description of water level - discharge model in Section 2.3 is not clear. Please give more details.
- The baseflow survey was performed in February, 2020 and the stormflow issue was carried out in September, 2020. How to quantify the uncertainty of the baseflow and storm flow Zinc loads in the sampling processes in this study? It is suggested to demonstrate it with more information in the revision.
- Line 131-132: "February was selected ...into the water body". Please add supportive evidences.
- The limited samples might be very weak to illustrate the baseflow and stormflow Zinc loads in the watersheds of interest. Please add some discussions about this critical issue.

Reviewer 2 Report
This is an interesting work, which clarifies the origin of contamination with Zn, contributing to the possibility of being treated and largely excluded, improving the water quality and aquatic life.
Introduction
It is very focused on the Zn issue. However, Fe and suspended solids (SS) were also evaluated. A brief explanation of the reason for evaluating these parameters should be given.
Material and Methods
In the site description, you should add data on temperature, lithology, and main types of soil (as these are important non-point sources).
Is river water used to irrigate agricultural crops in the surrounding area?
Results and Discussion
Despite having chosen to do a Results and Discussion chapter, it often separates both, especially in point 3.1. Can you rearrange the text? However, I think this is a good chapter.
Conclusions
Good
