Round 1
Reviewer 1 Report
General Comments.
1. The document, when analyzed on Plagiarism's software, i.e., Turnitin, is showing 18%. As per my view, it must be lower down up to 14% or so for an article. Self-Plagiarisms are also not accepted more than 2.5%.
2. The tables and figures used are not clear and can be enhanced. Heading must be with sequential numbers like 1.0, 1.1, 1.2, etc.
3. In reference section some reference is de-shaped, may be due to formatting. They are also needed to be corrected as per journal format.
4. The introduction must be reduced to one and a half pages.
5. The title needed significant modification.
6. The numbering of content must correct.
7. The manuscript requires an extension of the literature.
8. The manuscript does not illustrate great attention and activity in the field.
9. Tables also contain few references.
10. Please enhance the manuscript on analysis of earlier mention issues.
11. The figure number is distorted and can be rechecked.
12. For the text clarity, would you refrain from using additional words, mostly meaningless filler words, which can be omitted or some archaic words see, e.g. "respectively", "thus", "hence", "therefore", "furthermore", "thereby", "basically,", "meanwhile", "wherein", "herein", "Nonetheless", "Perceivably," etc.?
13. Major English correction is needed in each section.
Specific Comments.
Abstract: This section should be reorganized for consistency. It could also be shortened by deleting and synthesizing 2 or 3 sentences, or summarizing certain ideas.
- I suggest to present the original contributions after synthesizing the main results
- Please, specify the methodology after the research questions.
- The aim of the study could come after the literature gap and before the theory
Introduction: This section should be improved and supported by more and recent references. The authors must clearly demonstrate the relevance of the subject and the problem, justify the literature gap, show the main results and the originality of the contribution. The authors should describe the importance of their research more clearly. The references cited lack articles on contaminants from last year. So, add more references (2014-2021) to support the author's points of view. Last paragraph must be an outline of the complete study showing the needed and targets assumed in the paper. Hence need minor revision. It also suggestive to add latest article in references. Please use the literature background on cleaner production/sustainability (but not self-citations, please) to broaden the manuscript foundation. Please develop a better title.
Materials: More specific details are needed to be added with use of latest reference. Better use recent article for updating this section. Figure 1 and Fig.2 & 3 need more elaboration in text. To be convincing, the methodology should be justified and more detailed.
Results and discussion:it must clearly do not establish a strong environmental concerns (however, as much as possible, avoid self-citations). In your discussion section, please link your empirical results with a broader and deeper literature review. Discussions and conclusions must go deeper, it would be more interesting if the authors focus more on the significance of their findings regarding the importance of the interrelationship between the obtained results and sustainable development in the sector context, and the barriers to do it, what would be the consequences, in the real world, in changing the observed situation, what would be the ways, in the real world, to change/improve the observed situation.
Future scope of this study can be added as well as social impact can also be discussed in this paper.
Conclusions: Add this section and it needed to be free from any variables are symbols. Only main pointed like what was expected and what was achieved must be written. What signification contribution this study to the society must be mentioned in this section. Please make sure your conclusions' section underscores the scientific value-added of your paper and/or the applicability of your results. Highlight the novelty of your study. Clearly discuss what the previous studies that you are referring to are. What are the Research Gaps/Contributions? In your conclusions, please discuss the implications of your research

Reviewer 2 Report
In this manuscript, the influence of industrial wastewater on the water quality of the Bole Lemi River water around the industry park. This topic fits the scope of the journal. However its quality needs to be highly improved. I have some comments as below:
1. Is there any special reason for the sampling time ? from May and June 2021.
2. Did the industrial wastewater contain some contaminants? However the authors did not consider this aspect.
3. In the Abstract, "Results showed a varying concentration for temper-ature, EC, pH, TSS, TDS, COD, BOD, TN, and TP." What was the meaning of "concentration of temperature"? And why these indicators were selected?
4. No error bars can be found in the data. If the experiments were not repeated, the results of this study can be questionable.
5. Overll, the authors should clarify the novelty of this work, and major revisions are needed.
Weighted Arithmetic Index Method was used to estimate the water quality of the water samples using for Water Quality Index (WQI
