Analysis and Control of the Physicochemical Quality of Groundwater in the Chari Baguirmi Region in Chad

Round 1

Reviewer 1 Report

Dear Authors

In part of chapter 1. Introduction [l 33] there was no background relating to the issues analyzed in the study. Authors should conduct an initial literature search. The introduction is modest and only applies to the region. L 61, 2.2. Methods of analysis - in this section, please provide more details on the analyzes used or connect to the point Laboratory analyzes [L 69]

In my opinion, the discussion [I 297] should contain a bit more references. I believe that the statistical analysis was carried out correctly at work. However, I missed other - simple tools, such as box charts, frames - whiskers. Their results are clear and easy to interpret.

Reviewer 2 Report

The manuscript titled “Analysis and control of the physicochemical quality of groundwater in the Chari Baguirmi region in Chad” depicts an elaborate and comprehensive analysis of 12 physicochemical parameters in Chari Baguirmi region in Chad. The work is thorough and will provide important guidelines for future water quality management in that area. The writing and English grammar are also excellent and I enjoyed reading the manuscript. Therefore, I recommend acceptance in its current form or with minor corrections.

Couple minor corrections:

In many instances, there are paragraphs made of only one or two sentences. Please combine accordingly to make a paragraph with at least 4/5 sentences.

Figure 2 to Figure 12:

The plots quality should be improved. The x-axis data (samples) looks confusing and overlapping with one another. The gridlines should be removed or may be a few only. Y-axis label should also contain the units.
