  • Tapping the potential of codigestion

    Codigestion refers to processing multiple biodegradable substrates (feedstocks) in an anaerobic digestion (AD) system. A more contemporary definition refers to the digestion of a combination of select biodegradable feedstocks with a base substrate that an AD system was designed to handle. The intent is to maximize the production of biogas (i.e., renewable energy) by adding substrates that produce ...

  • Phosphate detection in water - a potential amperometric approach

    Excess phosphorus causes eutrophication (excess of nutrient promoting a proliferation of plants, (especially algae) inecosystems. Consequently, the monitoring of phosphate in waste, drinking and natural water is of major importance.There is a strong interest in a method alternative to the standard molybdate colorimetric method, which is not well suited to continuous monitoring under field ...

  • Forecasting fish biomasses, densities, productions, and bioaccumulation potentials of Mid‐Atlantic wadeable streams

    Regional fishery conditions of Mid‐Atlantic wadeable streams in the eastern United States are estimated using the BASS bioaccumulation and fish community model and data collected by the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP). Average annual biomasses and population densities and annual productions are estimated for 352 randomly selected ...

  • On-line monitoring of algae concentration with ALGco - Case Study

    The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. The ALGcontrol offers on-line monitoring of different kind of algae through fluometric a (fluorescence) technique. Fluorescence is the property of some atoms and molecules to absorb light at a ...

  • Online monitoring of algae concentration with ALGcontrol - Case Study

    Online monitoring of algae concentration with ALGcontrol The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Harvesting Corn Stover and Soil Quality

    Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn stover ...

  • Planting trees and managing soils to sequester carbon

    As of 2007, the shrinking forests in the tropical regions were releasing 2.2 billion tons of carbon per year. Meanwhile, expanding forests in the temperate regions were absorbing 0.7 billion tons of carbon annually. On balance, a net of some 1.5 billion tons of carbon were being released into the atmosphere each year, contributing to global warming. The tropical deforestation in Asia is driven ...

  • Ordinances To Amend Soils Boost Compost Demand

    Municipalities everywhere are realizing that some of the environmental issues they are grappling with locally may be mitigated by healthier soils. In the late 1990s, when Puget Sound Chinook salmon was listed as threatened, Washington State officials scrambled to find ways to improve water quality in the Puget Sound and protect spawning streams. They identified a number of methods to reduce ...

  • Sulphur mineralization kinetics of cattle manure and green waste compost in soils

    Sulphur mineralization of cattle manure (CM) and green waste compost (GWC) added to six agricultural soils with different chemical properties was monitored over 10 weeks in a laboratory incubation experiment. Although the amount of sulphur was higher in CM than in GWC, the cumulative SO4 2--S values in GWC-treated soils were higher than in soil amended with CM. The percentages of mineralized S ...

  • Decadal changes in Potassium, Calcium, and Magnesium in a deciduous forest soil

    Decadal changes in soil exchangeable K+, Ca2+, and Mg2+ concentrations and contents from 1972 to 2004 in eight intensively monitored plots on Walker Branch Watershed were compared with estimates of increments or decrements in vegetation and detritus. The results from these eight plots compared favorably with those from a more extensive set from 24 soil sampling plots sampled in 1972 and 2004. ...

  • Persistence of the tricyclic antidepressant drugs amitriptyline and nortriptyline in agriculture soils

    Amitriptyline and nortriptyline are widely‐used tricyclic antidepressant drugs. They have been detected in wastewater, surface runoff, and effluents from sewage treatment plants. As such, they could potentially reach agriculture land through the application of municipal biosolids or reclaimed water. In the absence of data on their fate in the environment, the persistence and dissipation ...

  • Recent carbon and nitrogen accumulation and acidification in soils of two Scots pine ecosystems in Southern Germany

    Abstract  Changes of the soil chemical status during the recent 22–30 years at two historically degraded forest sites in southern Germany (Pfaffenwinkel, Pustert) stocked with mature Scots pine (Pinus sylvestris L.) stands were studied by repeated soil inventories conducted in 1974, 1982–1984, 1994, and 2004 on replicated control plots of fertilization experiments, allowing a statistical ...

  • Modifying broiler diets with phytase and vitamin d metabolite (25-OH D3): impact on phosphorus in litter, amended soils, and runoff

    Received for publication April 14, 2009. Adding phytase and 25- hydroxycholecalciferol (25-OH D3) to broiler diets has been shown effective at reducing total P concentrations in broiler litter. This study was conducted to determine the impact of field application of broiler litter from modified diets on P solubility in litter-amended soils and P losses in runoff. Five broiler diets and their ...

  • Analysis of Selected Herbicides And Related Metabolites in a Coastal Lagoon Under The Influence of Water Runoff: Water Column

    Anthropogenic release of chemical contaminants, in particular pesticides coming from agricultural areas, significantly impacts European aquatic ecosystems. Pesticides and herbicides used in common agricultural practices, are applied only during specific periods of the year, leading to significant seasonal peak concentrations in fresh and coastal waters, particularly in spring after heavy rainfall ...


  • Impact of recycled water use at mammoth golf courses on basin groundwater quality

    ABSTRACT The Mammoth Community Water District’s proposed plan for recycled water use in golf course irrigation as a solution to the district’s water shortage problem develops concerns over protecting its basin groundwater quality. A detailed assessment through model development, and monitoring and testing is done in this study to determine the fate and transport of concerned pollutants in ...

  • Transport of lincomycin to surface and ground water from manure-amended cropland

    Livestock manure containing antimicrobials becomes a possible source of these compounds to surface and ground waters when applied to cropland as a nutrient source. The potential for transport of the veterinary antimicrobial lincomycin to surface waters via surface runoff and to leach to ground water was assessed by monitoring manure-amended soil, simulated rainfall runoff, snowmelt runoff, and ...

  • The development of a coupled model (PCPF-SWMS) to simulate water flow and pollutant transport in Japanese paddy fields

    A new coupled model (PCPF–SWMS) was developed for simulating fate and behavior of pollutant in paddy water and paddy soil. The model coupled the PCPF- 1, a lumped model simulating pesticide concentrations in paddy water and 1 cm-surface sediment compartment, and the SWMS-2D, a finite element numerical model solving Richard’s and advection-dispersion equations for solute transport in soil ...
