Summary: This study aimed to appraise seasonal variations in surface water quality on the coasts of Southwestern Vietnam using entropy-weighted water quality index (EWQI) and multivariate statistics: cluster analysis (CA), principal component analysis (PCA), and discriminant analysis (DA). Forty-nine samples monitored in Kien Giang province during the rainy and dry seasons were analysed for 16 physiochemical and biological parameters. Compared to the Vietnamese standard, surface water quality in the study areas was contaminated with organic matter (high biological oxygen demand and chemical oxygen demand), nutrients (high ammonium (NH4+), nitrite, and orthophosphate), total suspended solids (TSS), iron (Fe), and coliform. Seasonal variations in surface water quality in the coastal regions were observed. TSS, organic matter and microbial problems in water bodies tend to be more serious in the rainy seasons due to an increase in water flow containing pollutants from upstream and wastes from regional human activities. Meanwhile, the salinity in the dry season (0–32‰) was greatly higher, which caused only 10% of samples to be suitable for irrigation. CA extracted 11 and 13 clusters from 49 locations in the dry and rainy seasons, respectively. Five principal components obtained from PCA can explain 74 and 70% of total water quality variations in dry and rainy seasons, respectively. Moreover, the results of PCA suggested that natural factors (hydrological regimes, temperature, rainfall, sea-level rise) and human sources (domestic, agriculture, industry, and tourism) are accountable for these fluctuations. DA extracted 7 parameters (pH, TSS, salinity, Fe, nitrate, NH4+, and chloride) for leading the difference in water quality, with 88% of correct assignation. EWQI revealed that about 66% of total samples were classified as a very bad quality for drinking in the dry season. However, this ratio declined to 59% in the rainy season. Although the surface water quality was slightly improved during the rainy season, organic matter and microbial pollution need to be concerned. The findings of this study can provide insights into seasonal variations in surface water with the application of multivariate statistics and EWQI, which could support policymakers in developing water management strategies.

Summary: The study was conducted to analyze surface water quality fluctuations in the the southern region of Vietnam using monitoring data at 58 locations. Seventeen water quality indicators were analyzed including pH, temperature, electrical conductivity (EC), dissolved oxygen (DO), total dissolved solids (TDS), total suspended solids (TSS), chemical oxygen demand (COD), biological oxygen demand (BOD), ammoniacal nitrogen (NH4+- N), nitrite nitrogen (NO2−-N), nitrate nitrogen, iron (Fe), lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), and chloride (Cl− ions). The study used water quality index (WQI), cluster analysis (CA), principal component analysis (PCA), and Entropy weighted methods to analyze surface water quality. The results showed that the surface water was contaminated with organics (low DO and high TSS, BOD, COD), nutrients (high NH4+-N) and Fe. While Pb at some locations exceeded the allowable limit of the national technical regulation, other indicators (Cd, Hg and As) were within this standard. Moreover, DO, TSS, BOD, COD, NH4+-N, Fe, EC, TDS, and Cl− were seasonally fluctuated. WQI classified water quality from bad to very good (WQI = 42–100) due to the impact of hydrological conditions, navigation, wastewater from industrial zones, and fishing ports. The results of CA suggested that it is possible to reduce the 11 sampling locations (from 33 to 22 locations) in clusters 1–6 and the frequency of monitoring from 8 to 5 times per year, which still ensures representativeness of water quality over time. This reduction allows lowering the monitoring costs by 56.5%. The PCA identified five major potential sources explaining 87.3% and 8 minor sources explaining only 12.7% of water quality variation. Temperature, pH, EC, DO, BOD, COD, NH4+-N, NO2−-N, Fe, Cl−, Pb are important indicators need to periodically be monitored. Furthermore, orthophosphate, total phosphate, total nitrogen, coliforms should be considered to add into the next monitoring program. Locations with medium and bad water quality are concentrated in Dong Nai, Ho Chi Minh City and Long An, which requires finding effective solutions to improve the water quality. The current results can assist in decision-making related to environmental quality monitoring in the southern region of Vietnam.

Summary: Groundwater serves as an important resource for people in the Mekong Delta, but its quality has been continuously declined from human activities. Current status of the groundwater quality needs to be evaluated for sustainable groundwater resource management. This study aimed to evaluate the groundwater quality for drinking purposes in the Mekong Delta, Vietnam, using multivariate statistical methods and integrated-weight water quality index. Data comprised 8 water quality parameters (pH, total hardness, nitrate (NO3−), iron (Fe), lead (Pb), mercury (Hg), arsenic (As), and coliforms) obtained from 64 observation wells in An Giang province, Dong Thap province, and Can Tho city, were analyzed by cluster analysis (CA), principal component analysis (PCA), and integrated-weight water quality index (IWQI). The results indicated that most parameters were within standards while excessive hardness and Fe contamination were found in some regions. More than 80% of samples were detected with serious coliform contamination. The CA results revealed that groundwater quality heavily depend on geological locations with 4 clusters of the sampling locations. Three principal components obtained from PCA could explain 77.2% of the groundwater quality variation. The IWQI values ranging from 4 to 2761 classified groundwater quality as excellent (53.1%), good (25%), poor (9.4%), very poor (4.7%), and undrinkable (7.8%), which were associated with coliform contamination. These findings have provided insights into the groundwater quality status in the region, which can benefit in developing a water protection strategy.
