Phosphate and thermal stabilization of heavy metals in dredged sediments
… The U.S. EPA toxicity characteristic leaching procedure (TCLP) confirmed both phosphate addition and calcination reduced leachability of metals with the combined treatment achieving up to an 89% reduction. In beneficial reuse, the synthetic precipitation leaching procedure (SPLP) …

Properties and environmental impact from mosaic sludge industry incorporated into fired clay bricks
… tests such as Toxicity Characteristic Leaching Procedure (TCLP), Synthetic Precipitation Leaching Procedure (SPLP) and Static Leachate Procedure (SLT) were conducted to determine the results which complied with the United State Environment Protection Agency (USEPA) and Environment …

Stabilization/solidification of lead contaminated soil using cement incorporated with sugarcane bagasse
… (SCB) is added to remedy contaminated soil. Synthetic contaminated soil was prepared in bulk by mixing soil samples with lead nitrate, Pb (NO3)2 to achieve the concentration of 500 ppm. After that, cement is added at a proportion of 5%, 10% and 15% in sample weights without SCB while in …

Leaching of metals and metalloids from highway marking glass beads and the potential environmental impact
… fluorescence (FP-XRF) spectroscopy. A number of leaching studies were conducted and included two standard United States Environmental Protection Agency (U.S. EPA) methods: the toxicity characteristic leaching procedure (TCLP) and the synthetic precipitation leaching procedure (SPLP). In addition, …

Leaching behaviors of heavy metals on petroleum sludge waste treatment by using solidification/stabilization (s/s) method with palm oil fuel ash as partial cement replacement
… leachibility of the samples was determined by Synthetic Precipitation Leaching Procedure (SPLP), Toxicity Characteristics Leaching Procedure (TCLP) and Static Leaching Test (SLT). The results were compared with United States Environmental Protection Agency (USEPA) standards. The heavy metals in …

Stabilisation and solidification of contaminated soil using cement and sugarcane bagasse ash (SCBA)
… Absorption and Permeability test. In addition, leaching tests were performed to identify the leachate behavior of heavy metals during treatment. Three leaching tests were conducted and they were the Toxicity Characteristic Leaching Procedure (TCLP), Synthetic Precipitation Leaching Procedure …

Evaluating Leachability of Residual Solids from Hydraulic Fracturing in the Marcellus Shale
… operations in the Marcellus Shale to predict the leaching behavior of select elements in disposal environments. Samples collected for this research were: (1) drilling mud, (2) treated sludge from the chemical treatment of process waters, (3) solids from the gravity settling of produced water, and …
