Distribution of volatile organic compounds (VOCs) in surface water, soil, and groundwater within a chemical industry park in Eastern China
This paper focuses on the distribution of volatile organic compounds (VOCs) in the surface water, soil, and groundwater within a chemical industry park in Eastern China. At least one VOC was detected in each of the 20 sampling sites, and the maximum number of VOCs detected in the surface water, groundwater, and soil were 13, 16, and 14, respectively. Two of the 10 VOCs with elevated ...

Impact of pollution and seasonal changes on microbial community structure in surface water
We studied the differences in a microbial community structure with respect to the water pollution level and seasonal changes. The determination of phylogenetic groups of Bacteria and Archaea was done using fluorescent in situ hybridization (FISH). The total number of microorganisms was determined by direct counting of DAPI (4′,6-diamidino-2-phenylindole) stained samples using a fluorescence ...

Waste agricultural fibres highly effective removing water pollution in developing countries
Discharging different kinds of wastewater and polluted waters such as domestic, industrial and agricultural wastewaters into environment, especially to surface water, can cause heavy pollution of this body sources. With regard to increasing effluent discharge standards to the environment, high considerations should be made when selecting proper treatment processes. Any of chemical, biological and ...

Contamination of groundwater and the risk to human health
Groundwater is a major source of drinking water in many parts of the world. In industrialised countries, there is increasing concern that groundwater reserves are being contaminated by industrial effluents and the chemical pesticides and fertilizers used in intensive farming. This paper compares some of the existing guidelines for acceptable concentrations of certain common contaminants in ...

Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate
Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

Hydrochemical evaluation of surface water quality and pollution source apportionment in the Luan River basin, China
In the context of rapid economic growth in China, hydrochemical characteristics of stream water quality are being influenced by a variety of natural and anthropogenic inputs. We determined 10 hydrochemical parameters of the surface water at 29 monitoring sites in the Luan River basin of northern China during 2007–2009. Water quality hydrochemistry was evaluated using fuzzy comprehensive analysis ...

Pollution assessment of the impact of industrial effluents on the qualities of surface water and sediments of River Ona in Ibadan, Oyo state, Nigeria
River Ona, a major river in Ibadan, into which industries discharge their effluents, was studied to assess the impact of the industrial discharge. The mean levels for some parameters gave evidence of pollution. The mean values for DO (4.9 ± 0.3 mg/l), COD (54.5 ± 0.5 mg/l), PO43− (0.47 ± 0.09 mg/l), SO42− (20.65 ± 0.85 mg/l) were reported for the upstream region, while the downstream mean values ...

The effects of industrialisation on water quality and livelihoods in Lesotho
In Lesotho, some of the industrial wastewater discharges are being released untreated into the environment causing water pollution. This study investigates the extent and impacts of industrial water pollution in Lesotho and the associated effects on human livelihoods in the region. A combination of desk studies, in-field water sampling and socio-economic survey showed that industrial effluents ...

The challenges of water governance in Ho Chi Minh City
Population growth, urbanization, pollution and climate change pose urgent water challenges in cities. In this study the sustainability of integrated water resources management in Ho Chi Minh City (HCMC) was evaluated using the City Blueprint approach. The City Blueprint is a set of 24 dedicated indicators divided over 8 categories, i.e., water security, water quality, drinking water, ...

Evaluation of stormwater BMPs for implementing industrial stormwater permitting strategy
This study assesses the performance of stormwater best management practices (BMPs) in industrial sectors and their effluent quality to facilitate the development of technology-based numerical effluent criteria. Generally, retention ponds outperform other BMP types for reducing total suspended solids, and media filter and wetland basins outperform other BMPs for metal removal. Detention basins ...

Radiological safety and environmental monitoring aspects of mining and processing of uranium ore at Jaduguda, India
Low–grade uranium ore is mined and processed in India since the early 1970s. To adhere to the regulatory compliance monitoring of external gamma level, radon and long–lived alpha activity of ore dust is carried out in uranium mines. Apart from this, surface contamination is also monitored in radiologically important areas of ore processing plant. Exposure of occupational workers is evaluated ...

Nitrate Analysis of Water Samples Using a Benchtop UV-Vis Spectrophotometer
Nitrogen is naturally found in groundwater and surface water in the form of nitrate, nitrite, or ammonium. The EPA has established a maximum contaminant level of nitrate-nitrogen in potable water of 10ppm. This application presents results of UV-Vis analysis of nitrate concentrations in drinking water, ground water, and industrial wastewater, showing that the manual colorimetric method is ...

Monitor and Control TSS, pH & Algae - Webinar
Are elevated pH and TSS levels a concern? In wastewater and industrial ponds algae directly influence pH and TSS levels. Warm, stagnant, and nutrient-rich water creates the ideal conditions for algae to bloom. Making discharge into surface water or rivers difficult and risking (NPDES) environmental compliance. EJ Neafsay and Greg Eiffert will talk you through: How algae negatively affect pH, ...

Phytoestrogens in the environment: II. Microbiological degradation of phytoestrogens and the response of fathead minnows to degradate exposure
Phytoestrogens are endocrine active compounds derived from plants, including the isoflavones genistein and daidzein, and their methylated derivatives biochanin A and formononetin. These compounds have been detected at the µg/L level in the effluents of plant‐processing industries and municipal treatment plants, and at the ng/L level in surface water around the world. The persistence of ...

Toxicity Monitoring of Waste Waters from Tanneries with Microbiotests
Abstract : Waste waters from tanneries pose one of the most difficult problems for the treatment and subsequent discharge of such industrial effluents in surface waters. The biological breakdown of these wastes must be preceded by flocculation to prevent biomass inhibition from exposure to the toxicants present. Residual toxicity, however, persists in the supernatant after the chemical treatment, ...

Comparison of wastewater treatment processes on the removal efficiency of organophosphate esters
Organophosphate esters (OPs), widely used as flame retardants and plasticizers, are regarded as a class of emerging pollutants. The effluent of municipal wastewater treatment plants is generally considered to be the main contributor of OP pollution to the surface water. In this study, anoxic–oxic (AO) and University of Capetown (UCT) processes were selected to investigate the removal ...
