Potential health implications of water resources depletion and sewage discharges in the Republic of Macedonia
Potential health implications of deficient sanitation infrastructure and reduced surface water flows due to climate change are examined in the case study of the Republic of Macedonia. Changes in surface water flows and wastewater discharges over the period 1955–2013 were analyzed to assess potential future surface water contamination trends. Simple model predictions indicated a decline in ...

Decentralized Wastewater Treatment Solutions for Off-Grid Locations
Efficient, independent plants bring top-quality treatment to even remote areas Every human settlement, regardless of its size or location, requires an effective way of dealing with the wastewater generated by those who live and work there. Discharging untreated or inadequately treated sewage into the environment poses a risk to the environment and human health. It can also have broader ...

Sustainable management of household solid waste
In most countries, the majority of household solid waste is landfilled because of associated low capital, operation and maintenance costs. However, many existing landfills have exhausted their handling capacities and new facilities are faced with the problem of siting. Alternatives to traditional landfill practice are required to achieve sustainability in managing solid waste. This manuscript ...

Cryptosporidium spp. andGiardia spp. in surface water supply of Campinas, Southeast BrazilSurface water contaminated by domestic sewage discharges is a potential source of pathogens, including protozoa. During 2005–2006, the source water (Atibaia River) of the Surface Water Treatment Plant (WTP) of Campinas city, São Paulo, Brazil was sampled to obtain an assessment of Cryptosporidium oocyst and Giardia cyst concentrations. Calcium carbonate flocculation (CCF) and membrane filtration ...

Monitoring leachate composition at a municipal landfill site in New Delhi, India
Most of the landfills in developing countries do not have any liner at the base, or a drainage layer or a proper top cover, which results in the potential problem of groundwater/surface water contamination due to the leachate. Hence, to decide whether the leachate is to be collected and treated, or may be allowed to discharge into the adjoining soil or public sewer or surface waterbody, it is ...

Sustainability and the indispensability of politics: a study of sanitation partnerships in urban India
The chronic absence of hygienic sanitation for many urban Indians and the resultant contamination of surface water sources are a major cause for the poor environmental condition in most cities in India. In the past decade, public?private partnerships have been presented as an innovative strategy to rectify this pervasive problem. Numerous partnerships to improve sanitation have been launched in ...

Making MGP Wastes Beneficial
More than 11 billion gallons of coal tar were generated at MGP sites in the United States from 1816 to 1947. The types and quantities of waste discharged to surface waters from MGPs vary from site to site, and the disposition of several billion gallons is unknown and remains unaccounted for. Numerous locations in the United States have sediments and soils contaminated with wastes generated from ...

Novel
Bacteroides host strains for detection of human- and animal-specific bacteriophages in waterBacteriophages active against specific Bacteroides host strains were shown to be suitable for detection of human faecal pollution. However, the practical application of this finding is limited because some specific host strains were restricted to certain geographic regions. In this study, novel Bacteroides host strains were isolated that discriminate human and animal faecal pollution in ...

University of Washington portal - Case Study
Active Treatment and Wheel Wash Water Treatment In late 2008 construction began on the 3-year Seattle Light Rail University of Washington link connecting the university with downtown Seattle. Because this site drains to Lake Washington and the Montlake Cut the City of Seattle has put extra emphasis on protecting surface water from contaminated stormwater runoff. In fact, the city routinely ...

Hydrogeomorphological Controls on Groundwater Quality in the Rattaphum Catchment (Songkhla Lake Basin), Thailand
The Rattaphum Catchment comprises four major hydrogeomorphic units: mountains, footslopes, plains and inland swamps around a lake system. The area accommodates three main agroecosystems: vegetable, rubber and fruits. During the high-rainfall period, groundwater levels rise near to the soil surface in all agro-ecosystems. The high water levels remain for 3–4 months in the coastal plain, while in ...

Fate and spatial variations of polybrominated diphenyl ethers in the deposition within a heavily urbanized area: case of Paris (France)
In this paper, we present the first results on the geochemical cycle of PolyBrominated Diphenyl Ethers (or PBDE) in the Paris Region (France). In order to provide information about the distribution and mobility of eight PBDE congeners, we first determined the level of contamination of different environmental compartments: i.e. atmosphere, soils and waters. Atmospheric PBDE deposition was ...

Aerobic biodegradation potential of endocrine disrupting chemicals in surface‐water sediment at Rocky Mountains National Park, USA
Endocrine disrupting chemicals (EDC) in surface water and bed sediment threaten the structure and function of aquatic ecosystems. In natural, remote, and protected surface‐water environments where contaminant releases are sporadic, contaminant biodegradation is a fundamental driver of exposure concentration, timing, duration, and, thus, EDC ecological risk. Anthropogenic contaminants, ...

Integrated SUDS scheme overcomes challenges at low-lying manufacturing facility
The sustainable drainage system developed by ACO Water Management for Kybotech's new timber processing facility in Nottinghamshire fully integrates a number of SUDS processes to successfully overcome the site's many challenges. Situated in a restricted low-lying position close to the watertable, the system first removes all oil deposits and sawdust carried in run-off from both the handling yard ...

The Benefits of Biological Treatment for Drinking Water
The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...

Quantitative microbial risk assessment to estimate the health risk from exposure to noroviruses in polluted surface water in South Africa
This study assessed the risks posed by noroviruses (NoVs) in surface water used for drinking, domestic, and recreational purposes in South Africa (SA), using a quantitative microbial risk assessment (QMRA) methodology that took a probabilistic approach coupling an exposure assessment with four dose-response models to account for uncertainty. Water samples from three rivers were found to be ...

Determination of perfluorinated compounds (PFCs) in solid and liquid phase river water samples in Chao Phraya River, Thailand
Perfluorinated compounds (PFCs), especially perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), are fully fluorinated organic compounds, which have been used in many industrial applications. These chemicals have contaminated surface water all over the world even in developing countries like Thailand. The previous study showed the contamination in Chao Phraya River in 2006 and ...
