The Relau River Water Quality Analysis at the National Forest Reserve, Merapoh, Pahang

Abstract This research aims at using a combined water quality index (WQI) and pollution index (PI) to assess and characterize river water quality of Cau River which is one of the longest rivers in the north of Vietnam. Five different water quality and water pollution indices were used including the Water Quality Index (WQI), Comprehensive Pollution Index (CPI), Organic Pollution Index (OPI), Eutrophication Index (EI), and Trace Metal Pollution Index (TPI). The combined water pollution indices show more serious pollution towards the river downstream. In particular, CPI and OPI reveal a high risk of eutrophication. Cluster analysis was applied to classify water monitoring points into different quality groups in order to provide a better understanding of the water status in the river. This study indicates that a combined water quality analysis could be an option for decision making water use purposes while its single index shows the current situation of water quality.

The purposeofthis research is to analyze the water quality of Bengawan Solo River in Bojonegoro Regency. Water sampling was carried out at 6 monitoring points along the Bengawan Solo River in Bojonegoro Regency. Determination of sampling monitoring points, based on the differences of characteristics that exist in the study area. Some parameters issued are temperature, conductivity, COD, BOD, and Oil/ fat food which are then compared with the criteria for Class III standards of river water quality in accordance with the Regional Regulation of East Java Province Number 2 of 2008. Based on the analysis results obtained at each point monitor, area 1, is the most polluted area. It is caused, in this area, there are several activity of downtown. Households produce waste from bathroom, toilet, kitchen, washing clothes and washing household appliances.

Day By Day

As a developing country, industrialization is rapidly growing up in Bangladesh. Most of the cases, the industrialization process don’t considering any impact on environmental body. In this study, the impact of unplanned industrialization on the surface water is the main focus. In between several resources, the water quality of the Sitalakhya River is our study area. Quality of the Sitalakhya River water is getting polluted day by day through industrial effluents and household wastewater, lube oil and oil spillage around the operation of river ports. The Sitalakhya river water quality analysis is considered between 1975 to 2018, qualitative and quantitative results for pH, DO and BOD were analyzed and also trends of these parameters were also analyzed. Day by day river water quality going far away from EQS value, which is significantly harmful to flora fauna. In this circumstance, industrial effluent and other environmental impacts from unplanned industrialization is main goal of this study. This study shows, how unplanned industrialization can damage an environmental system which is very harmful to our entire ecological cycle. If cannot control this unplanned industrialization, water body will damage and all related ecosystem will be effected.
