TLDR
A fly ash-based stabilization/solidification (S/S) technique was investigated using field soil samples contaminated with arsenic (As) and lead (Pb) and a semi-dynamic leaching test was used to evaluate the effectiveness of the S/S treatment.About:

Effect of acid rain pH on leaching behavior of cement stabilized lead-contaminated soil.
TL;DR: It is observed that the lead contamination and cement content levels can have a considerable impact on the leaching behavior of the soils and the leachability of lead and calcium is attributed to the stability of the hydration products and their consequent influence on the soil buffering capacity and structure.

Sorption of heavy metals by inorganic and organic components of solid wastes: Significance to use of wastes as low-cost adsorbents and immobilizing agents
Ya-Feng Zhou,Richard J. Haynes +1 more
TL;DR: In this article, the properties of various waste materials (e.g., fly ash, slag, red mud, water treatment sludge, fungal and bacterial biomass, tree bark, sawdust, paper mill sludge and seafood processing waste, and composted organics) and the use of these materials as heavy metal sorbents, in situ immobilizing agents, and stabilization-solidification agents are examined.

Arsenic Waste Management: A Critical Review of Testing and Disposal of Arsenic-Bearing Solid Wastes Generated during Arsenic Removal from Drinking Water
TL;DR: Current disposal options for arsenic-bearing wastes, including landfilling, stabilization, cow dung mixing, passive aeration, pond disposal, and soil disposal are summarized and compared to results from shorter, regulatory tests.

Co-treatment of gypsum sludge and Pb/Zn smelting slag for the solidification of sludge containing arsenic and heavy metals.
Yuancheng Li,Xiaobo Min,Liyuan Chai,Shi Meiqing,Chong-Jian Tang,Qingwei Wang,Yanjie Liang,Lei Jie,Li-Yang Wenjun +8 more
TL;DR: The results indicated that the leached arsenic content was always less than 5 mg/L, which is a safe level, and does not contribute to recontamination of the environment.

Contamination of drinking-water by arsenic in Bangladesh: a public health emergency
TL;DR: The experience in Bangladesh shows that groundwater sources throughout the world that are used for drinking-water should be tested for arsenic, and the fundamental intervention is the identification and provision of arsenic-free drinking water.

Heavy metal speciation and leaching behaviors in cement based solidified/stabilized waste materials.
TL;DR: The leaching of heavy metals in the S/S materials can be considered as a pH dependent and corresponding metal hydroxide solubility controlled process.
