EXECUTIVE SUMMARY: The study tested the null hypothesis that there is no significant relationship between the pH Level of Rainwater and its amount of Rainfall, Ion Concentration and Electrical Conductivity in the Philippines. The data was provided by the Department of Environment and Natural Resources which includes the Philippine Data of Rainwater's pH Level, Amount of Rainfall, Ion Concentration which includes Sulfate, Nitrate, Chlorine, Ammonium, Sodium, Potassium, Calcium, Magnesium and Hydrogen concentrations and Electrical Conductivity gathered from the three Philippine Stations. The data were used to determine the relation between: pH Level and Amount of Rainfall; pH Level and Sulfate Ion Concentration; pH Level of Nitrate Ion Concentration; pH Level and Chlorine Ion Concentration; pH Level and Ammonium Ion Concentration; pH Level and Sodium Ion Concentration; pH Level and Potassium Ion Concentration; pH Level and Calcium Ion Concentration; pH Level and Magnesium Ion Concentration; pH Level and Hydrogen Ion Concentration; and pH Level and Electrical Conductivity recorded in the three (3) local stations. Based on the findings, generally, failed to reject the null hypothesis that there is no significant relation between the Amount of Rainfall and pH Level of rainwater in the Philippines. In Station 1, NH4 and K+ showed significant relation; Cl and K+ in station 2 and H+ in station 3 respectively. All other ions did not have correlation to pH. There is no significant relation between the electrical conductivity and pH Level. These results support the conclusion regarding the insignificant correlation between the pH and the Electrical Conductivity in all stations. Electrical Conductivity is directly related to concentrations than pH, and the Amount of Rainfall is independent of both. Recommendation include periodic data collection and large scale sampling.
