  • 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. ...

  • A soil quality index for reclaimed mine soils

    The quality of soils found in mines is low if they do not receive any reclamation treatment. To our knowledge, there are no still equations to evaluate the quality of metal contaminated mine soils after the application of the reclamation treatments mainly in use today (planting vegetation and amending with wastes). Therefore, the purposes of the present study was (i) to propose a method for ...

  • Impact of using paper mill sludge for surface-mine reclamation on runoff water quality and plant growth

    Paper mills generate large amounts of solid waste consisting of fibrous cellulose, clay, and lime. Paper mill sludge (PMS) can improve reclamation of surface-coal mines where low pH and organic-carbon levels in the spoil cover material can inhibit revegetation. When applied at high rates, however, PMS may adversely impact the quality of surface runoff. Therefore, we applied PMS at 0, 224, and 672 ...

  • Reclamation of unconventional water using nano zero–valent iron particles: an application for groundwater

    Nano zero–valent iron (nZVI) is one of the most prominent examples of a rapidly emerging technology for the treatment of contaminated soil and groundwater. These particles were used successfully to absorb various heavy metals (e.g., Pb2+, Ba2+, As5+, As3+, Cr6+, Co2+, Cd2+, Cu2+), chlorinated organic contaminants (e.g., ...

  • Soil baked to clean up contamination...

    Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...

  • Surfactant–enhanced remediation of soils contaminated with petroleum hydrocarbons

    An experimental programme was undertaken to reclaim the soils contaminated with petroleum hydrocarbons. Two types of locally available soils, clay with low compressibility and poorly graded sand, were chosen for the study. Both the soils were contaminated with varying percentages of used engine oil and gasoline. Anionic surfactant Sodium Dodecyl Sulphate (SDS) was used to reclaim the contaminated ...
