While all other water samples were within the permissible limit, the recorded 643.2 mg/L TDS value for the Initao sample and 578.4 mg/L for Gitagum were beyond the limits set by PNSDW and USEPA.
All total hardness data of water samples from all locations have values that are within the PNSDW standard limit of 300 mg/L CaCO3, except for Libertad.
Overall, these results may indicate potential levels of ions [2,13,21] The TDS result was in agreement with the conductivity result which was site specific in terms of variation (p value = 0.010381; refer to Table 6), exceeding PNSDW drinking water standard (refer to Figure 6) [1].
