The study provided the status of pesticide use in three ecological regions in Kien Giang province. The management and use of pesticides were still inadequate due to not being fully aware of their harmful effects, leading to environmental pollution, which affected rural community. The soil, surface water and groundwater analysis showed that environmental pollution was a significant concern. The soil acidity was low to moderate, soil organic matter was deficient and soil was contaminated with heavy metals such as Pb, Zn, Cu and As. In terms of surface water, salinity regulated the studied sites in the dry season, TSS of 5/9 sites was higher than the standard, Coliform of 4/9 sites was 46 times higher than the standard, DO was less than 5 and BOD was 2-3 times higher than the standard. Surface water nutrients N-NO3- and N-NH3- were below the allowable threshold, P2O5 of 2/9 sites exceeded the allowed standard, N-NO2- of 5/9 sites exceeded the standard. Regarding the groundwater, the pH was neutral, the TSS at all sites was over the threshold, the water hardness of 2/9 sites exceeded the threshold, the Coliform at all sites was over the threshold and 3/9 of the areas were contaminated with Escherichia coli. This study showed that the perception of using pesticides in the study regions has to be changed.
