The results in Table 9 show that the pH of water is raised at the inlet (7.12) and decreased in the irrigated perimeter
(6.73) and then increases slightly towards the outlet of irrigated perimeter (6.85). By referring to Table 7
showing the pH interpretation standards, water was found to be neutral at the inlet (6.9 - 7.6), slightly acid in the
perimeter and outlet of it. This would be due to the use of fertilizers and pesticides. For water salinity, we found
that the results interpretations are similar to those for the pH. This means that the salinity is high at the inlet of
the irrigated perimeter with a value of 465 μs/cm, low in the irrigated perimeter with a value of 317.5 μs/cm and
increases to 355 μs/cm at the outlet of the irrigated perimeter. Compared to the World Health Organization
(WHO) standards, for the salinity range of 250 μs/cm to 750 μs/cm, the risk is said to be medium. In terms of
our study, the salinity of our three sampling points is showing a medium risk, because the values are between the
limits of the tolerable margin, Table 8.
