Waters quality test based on macrozoobenthos bioindicator parameter in the Bolong river, Magelang

The exploration of macrozoobenthos diversity as a bioindicator parameter in the Bolong river, Magelang has not been widely carried out. This study aims to determine the water quality of the Bolong river based on macrozoobenthos Bioindicator parameters. This research method uses a qualitative descriptive approach. The water quality test is measured based on the level of macrozoobenthos diversity according to the Shannon-Wienner diversity index. The purposive sampling method is used to determine 5 stations for sample collection. The intake of macrozoobenthos is done by using a Surber net and a tray at the bottom of river waters. Moreover, sampling is carried out with three repetitions. The data is analyzed using a diversity index, uniformity index, and dominance index to determine the water quality based on the Bioindicator parameters. Based on the result of the study, the macrozoobenthos diversity index is 1.028. Based on this index, the quality of waters in the Bolong river is considered as moderate pollution

Water pollution evaluation as consequent of old wells oil exploration

This research was aimed to investigate effect of oil spills on surface water from exploration in Dutch well.The investigation was carried out by in situ measurement of some parameters.Water sample was collected by grab sampling method and the analysis was conducted at Laboratory of Environment Badan Lingkungan Hidup dan Penelitian Pengembangan (BLHPP) Kabupaten Musi Banyuasin.The measurement result showed that some parameters did not fulfill the requirement of Standar Quality for Domestic Water Regulation according to Government Regulation No. 82 year 2001 i.e. COD and Oil&Fat content. The surface water and shallow ground water quality had some parameters that did not comply with standar quality according to regulation such as BOD, COD, DO, and oil-fat content.Calculation of pollution indeks (PI) showed that domestic water has 3.26 and was categorized into slightly polluted. At surface water in Angit River, the calculation of PI showed that upstream river was slightly polluted (3.23), while midstream was slightly polluted (3.22) and in downstream river was mildly polluted (9.60).

SELECTION OF SUSTAINABLE DOMESTIC WASTE MANAGEMENT TECHNOLOGY CASE STUDY: TANJUNG MEKAR VILLAGE, KARAWANG

The Citarum River is one of the rivers that is a source of clean water and is consumed by residents in the watershed and in DKI Jakarta. Currently, the Citarum River is facing serious environmental problems because it is a reservoir for waste from various sources such as factory, hotel and hospital waste as well as domestic waste, silting, problems with embankments and final treatment sites that are harmful to health. The results of monitoring the water quality of the Citarum River show that the water of the Citarum River has not been able to meet the water quality standards that have been determined based on the SK. West Java Governor No. 39 of 2000. The decline in water quality is caused by an increase in the pollutant load originating from the population, industrial development, extensification and intensification of agricultural land, fisheries development, livestock pollution and mining and excavation exploration. The focus of this research is emphasized on the river pollutant waste management program from domestic waste originating from community activities in Tanjung Mekar Village. The purpose of this study was to analyze waste management systems and domestic wastewater that are easily applied by the community, especially along rivers, in supporting community-based environmental management

Acid Rain in Niger Delta Region: Implication on Water Resources Quality and Crisis

This research focused on the effect of acid rain on the water quality of the Niger Delta region of Nigeria. Three hundred water samples were collected: 100 water samples from rain, 100 from open wells and 100 from rivers. The water samples were analysed using the paired t-test and multiple correlation analysis to ascertain their level of variation and relationship. Hydrochemical analysis revealed moderately low pH values of 4.98 > 5.12 > 5.23 for rain, river and well water resources in the Niger Delta region. The anions, cations and microbiological characteristics in river and well water sources before rain events were generally greater after down pours. This indicates that the pH values of rain water resources correlated significantly (r = 0.80) with gas flaring, an activity connected with petroleum exploration activities in the Niger Delta region. The acid content in the rainwater not only lowers the quality of rainwater sources for domestic use, but also the quality of well and river water sources in the region. This has led to acute drinking water shortages in the region and has exacerbated struggles for the few existing clean water sources. The cessation of gas flaring as well as the provision of adequate potable water supply to locals is highly recommended. Additionally liming of the water resources and other methods of cleansing acidic water may be employed in the interim.Keywords: Acid rain, well, river and water crisi

An Innovative Holistic Approach to an E-flow Assessment Model

River water resources provide a wide range of necessary ecosystem services, including regulating, provisioning, supporting and cultural services. Ecosystem services are linked to an appropriate level of functionality of river water resource processes, which can be connected with river basin environmental objectives. Environmental objectives can be achieved only if appropriate flow and sediment regimes and related river morphology quality are guaranteed. The obligation to define environmental flow (E-flow) in the European Union Water Framework Directive European (WFD) is not explicit, and the implementation of the WFD is more focused on water quality. Considering the specific climatic, hydrographic and hydrological conditions and the definition of E-flow, each EU country has developed procedures for their investigation and determination. In the Republic of Croatia, no methodology has been elaborated, nor is there any legal regulation to define E-flow downstream of a dam or water intake site. This paper presents the significant pressures that have affected the transboundary rural Sutla River basin between Croatia and Slovenia. These pressures can cause changes in the hydrological regime and biological elements of water quality. The holistic approach defines the E-flow for a profile on the Sutla River by linking hydrological, morphological, and ecological characteristics based on the exploration of the Sutla River and its biological communities. The full implementation of a holistic approach and the transition to Level III of the E-flow definition requires the enhancement of exploratory hydrological and biological monitoring that enables the use of habitat modelling. Doi: 10.28991/cej-2020-03091611 Full Text: PD

A baseline report of water quality and invertebrate assessment in River Hohwa, Lake Albert: final report

Tullow Oil plc is to launch an onshore Early Production System (EPS) of oil drilling rated at 4,000 barrels of oil per day by 2009. The location of the EPS is in the Kaiso-Tonya area of Block 2 Oil Exploration Zone along Lake Albert within the Albertine graben. Tullow Oil plc contracted Environmental Resources Management (ERM) Southern Africa (Pty) Ltd in conjunction with Environmental Assessment Consult Limited (EACL) to undertake an Environmental Impact Assessment (EIA) for pre-construction and operation of the proposed EPS. ERM in association with EACL requested National Fisheries Resources Research Institute (NaFIRRI) to conduct a baseline survey of water quality and invertebrates in River Hohwa. This study was requested as part of an earlier baseline survey conducted at the Kaiso-Ngassa spit oil exploration area in Block 2. It was conducted at five selected sites (Fig. 1 & Table 1) within the Hohwa River basin in the Kaiso-Tonya Exploration Area 2. The study was pertinent because the targeted oil wells for EPS are upstream this river which drains the Kaiso-Ngassa valley into Ngassa lagoon

This report gives the baseline information specifically on water quality (physical/chemical, nutrient and phytoplankton biomass status) of the open part of the lake, a river flowing into the lake and a lagoon, within Butiaba-Wanseko area. Oil and gas exploration in the Albertine Graben are on-going activities by Tullow Oil Plc, and Heritage Oil and Gas (Heritage). Part of the activities involve 2-D TZ seismic surveys in exploration area Block 2 (Butiaba-Wanseko area) in Buliisa District. A study of the transition zone (basically along the shoreline was undertaken by National Fisheries Resources Research Institute (NaFIRRI) on behalf of Environmental Assessment Consult Ltd (EACL) during September 2007. A major objective of the study was to carry out a baseline survey of the fisheries and water quality of the lake shore between Wanseko and Butiaba prior to the proposed 2-D Seisimic investigation

Reliability of stored river water as an alternative for consumption in Ekpoma, Nigeria: a human health risk assessment

With looming global water-related issues, the monitoring of water quality for household and industrial consumption has become more pertinent. Rivers in nearby towns serve as primary water sources for Ekpoma town. 123 samples of stored river water were collected from 41 sampling locations and physical properties - pH, electrical conductivity (EC), salinity, temperature, and total dissolved solids (TDS) - were measured in situ using the Hanna edge® Multiparameter EC/TDS/Salinity Meter-HI2030. Atomic absorption spectrophotometry (AAS) was used to detect and measure the concentration of potentially toxic metals (PTMs): Al, Cr, Cu, Fe, Mn, Ni, Pb, and Zn. The measured concentrations were compared to the WHO, US EPA, and NSDWQ regulatory standards, and a spatiotemporal health risk analysis was performed using HERisk software. Twenty-five percent of the tested samples contained PTM concentrations within the allowable regulatory limits. Spatiotemporal health risk analysis showed that 98.8% of the cumulative carcinogenic risks (CRcum) were entirely from Pb contamination via oral ingestion. PTM concentrations in the samples suggest the degradation of river water quality due to agricultural activities, crude oil exploration activities, and soil composition in the region. Best management practices (BMPs) and treatment processes for the removal of detected contaminants are recommended to improve water quality
