  • Persistence of estrogenic activity in soils following land application of biosolids

    Estrogenic compounds may enter the environment when biosolids are applied to land. In the present study, soil samples were collected over 4 mo from a field trial following addition of biosolids. The recombinant yeast estrogen screen bioassay identified estrogenic activity in the soil at all sampling times to concentrations up to 2.3 µg 17β‐estradiol equivalency/kg. The present results indicate ...

  • Biosolids Applied to Land: Advancing Standards and Practices

    Summary Wastewater treatment in the United States is a major cornerstone of efforts to keep the nation’s waters clean. Sewage sludge is the solid, semisolid, or liquid residue generated during treatment of domestic sewage. Since the early 1970s, the U.S. Environmental Protection Agency (EPA) and the wastewater treatment industry have promoted recycling of sewage sludge. With the prohibition of ...


  • An Advanced Biosolids Treatment Process and Potential Beneficial Applications of the Processed Biosolids

    ABSTRACTAn innovative and cost-effective biosolids treatment and processing technology was developed and demonstrated at a pilot and full-scale at the Guelph Wastewater Treatment Plant in Ontario. The Lystek process involves a low but optimized application of heat, alkali, and mixing in a batch or semi-continuous system to achieve the desired physical, chemical and microbiological characteristics ...

  • Long-term effects of land application of class B biosolids on the soil microbial populations, pathogens, and activity

    Received for publication August 7, 2009. This study evaluated the influence of 20 annual land applications of Class B biosolids on the soil microbial community. The potential benefits and hazards of land application were evaluated by analysis of surface soil samples collected following the 20th land application of biosolids. The study was initiated in 1986 at the University of Arizona Marana ...

  • Soil carbon sequestration resulting from long-term application of biosolids for land reclamation

    Investigations on the impact of application of biosolids for land reclamation on C sequestration in soil were conducted at Fulton County, Illinois, where 41 fields (3.6–66 ha) received biosolids at a cumulative loading rate from 455 to 1654 dry Mg ha–1 for 8 to 23 yr in rotation from 1972 to 2004. The fields were cropped with corn, wheat, and sorghum and also with soybean and grass or fallowed. ...

  • Estimated occupational risk from Bioaerosols generated during land application of class B biosolids

    Some speculate that bioaerosols from land application of biosolids pose occupational risks, but few studies have assessed aerosolization of microorganisms from biosolids or estimated occupational risks of infection. This study investigated levels of microorganisms in air immediately downwind of land application operations and estimated occupational risks from aerosolized microorganisms. In all, ...

  • Human health risk assessment of triclosan in land‐applied biosolids

    Triclosan (TCS; 5‐chloro‐2‐[2,4‐dichlorophenoxy]‐phenol) is an antimicrobial agent found in a variety of pharmaceutical and personal care products. Numerous studies have examined the occurrence and environmental fate of TCS in wastewater, biosolids, biosolids‐amended soils, and plants and organisms exposed to biosolids‐amended soils. TCS has a propensity to adhere to organic carbon in ...

  • National Biosolids Overview

    In all, the 1990s have been good for the biosolids recycling community. Greater quantities of biosolids are being beneficially used than ever before, there are national biosolids regulations that are widely accepted as a good baseline, and there is an extensive, accessible network of researchers, practitioners, advisers and public officials who when combined, provide thousands of years worth of ...

  • Small-Scale Biosolids Composting

    Cambridge, Ohio retrofitted a portion of its vacuum assisted drying beds into a covered composting facility, processing about 300 dry tons/year of biosolids and wood chips. Like many small communities in an agricultural area, the City of Cambridge, Ohio (pop. 14,000) managed biosolids generated by its 2.25 mgd Water Pollution Control Center (WPCC) via land application on farm fields. “Then ...

  • Oquirrh Mt. Biosolids Composting Facility

    Biosolids Composting at Waste Water Reclamation Facility utilizing the MOR, Inc. Covered Aerated Static Pile (ASP) Composting System.  Facility has eliminated disposal costs associated with land application and landfill by composting biosolids on site and producing at Class A STA approved soil amendment for sale to the public.  The facilty utilizes the MOR, Inc. cover system to reduce ...

  • The effects of biosolid application on soil chemical properties and Zea mays nutrition

    BackgroundThe application of biosolid as a fertilizer in agricultural cultivation is a common practice in many countries. This study investigates the effects of sewage sludge and compost usage on soil chemical properties and Zea mays nutrition in comparison with those of iron and manganese sulfate solution. The experiment was carried out in a completely randomized block design with the following ...

  • Biosolids Composter Satisfies Customers and Neighbors

    A ticket to Penn State football games isn’t the only hard thing to come by in State College, Pennsylvania. So is the biosolids compost produced by State College’s University Area Joint Authority (UAJA) wastewater treatment plant. “For the last four years, we’ve been sold out before we’ve made the compost,” says Stephen Welch, who manages the UAJA composting plant. All biosolids generated — about ...
