Clear the following questions so I may try to answer.
1. These samples are taken from the same water at different time?
2. Different water source at the same point?
3. Different water sources at different time?
4. Same water at different point and different time?
5. Other
@Nafees Mohammad...the water samples are taken from different source (Different municipal wastewater treatment plants) at the same time (Same day).
Well,
Standard deviation, mean, mean+ SD, mean-SD, Coefficient of variation.

Sincerely
You can use the t-test or ANOVA to determine if the variation is significant or insignificant.
@Emad.......please elaborate on the use of ANOVA for such data. Because, as far as I know, ANOVA works when you have two or more column or row.
We can one -way ANOVA and Two-way ANOVA. I can help you to determine that.
