  • Quantification of exposure to fecal contamination in open drains in four neighborhoods in Accra, Ghana

    In low-income countries, rapid urbanization adds pressure to already stressed water and sanitation systems that are critical to the health of communities. Drainage networks, designed for stormwater but commonly used for disposing of waste, are rarely covered completely, allowing residents to easily come into contact with their contents. This study used spatial mapping, documentation of ...

  • Working in confined spaces: did you cover your risks?

    Most industrial facilities have confined spaces. They often get overlooked because access to them is rare. Not surprisingly, many facility managers believe there is no particular reason for concern.  The awakening could be a rude one, as several managers have faced criminal prosecution and substantial fines as a result of fatal accidents. The issue of work in confined spaces is a historical ...

  • Nitrate-nitrogen, Land Use/Land Cover, and Soil Drainage Associations at multiple spatial scales

    Managing non–point-source pollution of water requires knowledge of land use/land cover (LULC) influences at altering watershed scales. To gain improved understanding of relationships among LULC, soil drainage, and dissolved nitrate-N dynamics within the Calapooia River Basin in western Oregon, we selected 44 watersheds ranging in size between 3 and 33 km2 for monthly synoptic sampling of surface ...

  • River Basin

    A river basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The river basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is separated from adjacent basins by a drainage divide. The ...

  • Restoring Peatlands in Russia - Preventing peat fires, mitigating climate change

    Millions of hectares of drained and abandoned peatlands in European Russia are highly vulnerable to fires, such as those that covered Moscow in smoke during the extremely dry summer of 2010. Rewetting degraded peatlands, especially abandoned peat mining sites, and establishing a sustainable usage will prevent fires and their negative impacts on climate and biodiversity. Cause and threats ...

  • ADP Submission on mitigation potential of peatlands

    Peatlands in drained state cause 5% of current global CO2 emissions, while these drained peatlands cover only 0.3 percent of the global land surface. This means that peatlands should be treated as hotspots for emissions reductions; i.e. as areas of land with very significant emissions, but which enables to concentrate MRV investments. The trend of conversion is very rapid, especially in the ...

  • Quantitative Microbial Risk Analysis to evaluate health effects of interventions in the urban water system of Accra, Ghana

    A quantitative microbial risk assessment was applied to evaluate the microbial risks of the Accra Urban Water System (AUWS). The exposure assessment was based on the count of indicator organisms in waste water from open roadside drains and in water and sand samples from the beach. The predicted total disease burden generated in a representative catchment of the AUWS (Odaw Catchment) was 36,329 ...

  • GTI and the City of Tulare celebrate 25 years of converting waste to energy - case study

    Energy conservation has always been extremely important to both the City of Tulare and the wastewater treatment facility. Since biogas can be used as fuel to generate electricity, the city wanted a means to reliably collect biogas from the BVF® reactor to recover the energy while also controlling odors and reducing greenhouse gas emissions. To address the City of Tulare’s needs, ...

  • Base flow nutrient discharges from lower delmarva peninsula watersheds of Virginia, USA

    Received for publication August 11, 2008. Proper management of shallow coastal systems, which are vulnerable to nutrient enrichment, requires knowledge of land use impacts on nutrient discharges. This study quantified base flow nutrient concentrations and yields for 1 yr (May 2001–April 2002) from 14 first-order streams on the Virginia Eastern Shore (VaES) on the Delmarva Peninsula and assessed ...

  • Using the Clean Development Mechanism to mitigate emissions from peatlands: “Avoided drainage” and “Rewetting” as new CDM activities

    Introduction Currently, the only land-use, land-use change and forestry (LULUCF) activities that are eligible under the Clean Development Mechanism (CDM) are afforestation and reforestation (A/R), which allow for the generation of credits by net removal by sinks. This could include afforestation and reforestation of wet organic soils (peatlands), e.g. with peatswamp forest tree ...

  • Position paper: Accounting for peatland hotspots in the new climate agreement

    Introduction Peatlands (~organic soils) worldwide store twice as much carbon as all forest biomass, although they cover only a tenth of the land. The drainage of peatlands, for forestry and agriculture, leads to the oxidation of this carbon and increases their vulnerability to peat fires, leading to huge emissions of greenhouse gases. Hotspots for mitigation ...
