Objective: With the increasing attention to health influence by ecology environment and climate changes, it is important to explore the characters of drinking water quality and meteorological factors at tropical areas of South China. This study aims to study the water quality of municipal source water and to elucidate the relationship between water quality changes and climatic factors at Haikou. Methods: By analyzing the data of water quality indexes of source water in the past five years from July 2013 to April 2017, the representative indexes as following were analyzed: Fecal coliforms (FC), ammonia nitrogen (NH4+), Nitrate(NO3-), iron(Fe), permanganate Index(CODMn), fluoride(F), arsenic(As), chloride (Cl-). The methods of normal test, rank test and rank correlation were used to explore the water quality and the infuence by precipitation, temperature and sunshine. Results: Only the CODMn was normal distribution for the above indexes. For the five years, Mean of FC was of 110 MPN/L, NH4+ was 0.18 mg/L, Fe was 1.07 mg/L, CODMn was 1.67 mg/L, F was 0.14 mg/L, As was 0.0020 mg/L, NO3- was 1.12 mg/L, Cl- was 7.10mg/L. By the rank correlation test, CODMn, NH4+ and Fe was positive correlated with temperature, it was respectively (r=0.483, P=0.049), (r=0.310, P=0.045), (r=0.423, P=0.039). There is negative correlation for nitrate and chloride between temperature, it is respectively (r=-0.577, P=0.003) (r=-0.317, P=0.042); the indicators are not related to other two climatic factors. Conclusion: The source water has a higher concentration of iron. The temperature is an important factor that affects the local source water quality of Haikou. It is necessary to strengthen removing CODMn, NH4+ and Fe at the torrid period for drinking.
