Reviewer 2 Report
This work aims to test the effectiveness of an in situ remediation methodology based on the immobilization of these PTEs through the application of zero-valent iron nanoparticles (nZVI). It contains some new results which may be interesting to some Geosciences readers. Therefore, I recommend publication of the manuscript after addressing the following comments:
The manuscript must be edited by a senior author or an English professional to improve English level along with some minor corrections. Some of the English errors are listed below:
“…were cross-checked with the…” should be replaced with “…was cross-checked with the…”.
“…suitable technique for reduction the risk…” should be replaced with “…suitable technique for reducing the risk…”.
“…once nano dimensional and stable at superficial conditions.” should be replaced with “…once nano-dimensional and stable under superficial conditions”.
“behaviour" should be replaced with “behavior” all over the manuscript.
“…part of the of Três Marias formation…”
“…it was placed washed and disinfected…”
“…the nZVI are an important reducing agent that, in aqueous media, react…”.
The abstract needs improvement. Please add more information on the research results. It should be informative and completely self-explanatory and should not include experimental procedure.
The introduction should start with stating the objectives of the work and providing an adequate background, avoiding a summary of the results.
Figures should be labeled as (a), (b), (c)… followed by a descriptive caption or title.
Figures captions should clearly describe the figures with more detail.
Following references should be cited to improve the quality of the paper:

The results and discussion section should be improved. It should be presented with clarity and precision, should be explained by referring to the literature, and should interpret the findings in view of the obtained results.
