Assessing Water Quality of Te Teuk Pus Hot Spring in Kampong Speu Province of Cambodia
Abstract
The aim of the present study is to investigate water quality and potential trace metal contaminations in the hot spring of Cambodia. The sampling was conducted in Te Teuk Pus hot spring which is located in Kampong Speu province of Cambodia. Eleven water samples were collected from the Te Teuk Pus hot spring and were analyzed by Hanna COD and Multiparameter Photometer HI 8 099 and Hach DR 1900 Spectrophotometer. The physicochemical parameters were measured on-site using Hanna pH/ORP/ISE Meter and EC/TDS/NaCl Meter. Analytical results reveal that the temperature of the Te Teuk Pus hot spring range from 43.67℃ to 63.00℃ with an average of 47.83℃. The mean pH (9.02) of the hot spring is higher than the regulation limit of WHO’s drinking water quality guideline (DWQG) and Cambodian drinking water quality standard (CDWQS). A comparison reveals that As, Cr, Cu, and Fe concentrations are lower than WHO’s DWQG, but Cr, Cu and Fe concentrations in the Cambodian hot spring water are higher than those of Taiwan (Fanfan) and Turkey (Cermak). Mean Mn concentration of the Te Teuk Pus hot spring is higher than that of Vietnam, Thailand, Taiwan, Turkey, and Iran. Ca2+, Cl2, Mg2+, NO2-, NO3-, PO43-, SO42- and SiO2 are found lower than the regulation limits of WHO’s DWQG. This study suggests that this Te Teuk Pus hot spring water is acceptable for general use. However, further assessment of thermal tolerant bacteria should be made to prevent public health and tourists’ recreational activities.
