•	The language (both spelling and grammar) and sentence structures need extensive revision. For example: The extent to which they can provide a complete description of the situation is very “limits” as they always...; … takes a long time, which assists in the delay of “decision and in turn in strategic plans”.
•	The abstract needs to be modified, since it’s a copy from the last paragraph on page 2.
•	The style of writing references within the text needs correction. When the number of authors exceeds a two authors, one just writes “First Author et al.”.
•	Is it HiWaMIS or HyWaMis that stands for Hyderabad Water Management Information System? When both the full name and the acronym are stated once, there is no need to repeat the full name again (2nd page, 5th paragraph).
•	 In the 2nd section, Geographical setting, the area of the lake is stated in km, instead on km2.
•	Smalls and capitals need to be checked, (section 2.1. 2nd paragraph).
•	“Decision makers would take their decision to stop these charges by indicating the factors that affect the lake seriously which will be detected through GIS application, so that urban planners and decision makers can move as shown in figure 1.” It is not clear, how figure 1 indicates the “moves” of urban planners and decision makers. 
•	Table 1; Figures 2, 3; as well as Graphs 1 & 2 are not clearly referred to within the text.
•	Consider black/white printing when referring to colors of objects.
•	It was stated at the end of the introduction that section 4 of the paper will “describe the mapping technique to examine contamination of water…”. However, only the “results” were projected in that section without any details of the means and methodologies of reaching those results.
•	It would significantly enhance the work, if more stress is given to particulars rather than generals. So instead of stating the capabilities of GIS, more focus needs to be given on the methodology carried out in this research.
•	There is no clear mentioning of the attribute data used to come out with the research results. Mentioning this data (as few as they might be), and how they were processed, will increase the value of the presented work.
