The suitability of fly ash based geopolymer concrete as a replacement for ordinary Portland cement (OPC) concrete depends on the mobility of elements from the material. Due to the alkaline nature of geopolymer concrete, there is a potential for th...
Coal ash impoundments, along with other industrial and natural processes, can be sources of constituents of concern (COCs) to human health including arsenic (As), chromium (Cr), selenium (Se), and vanadium (V). Attempts to model the fate and trans...
An emerging strategy for the management of flue gas desulfurization wastewater involves volume reduction of the wastewater by concentrating to brine and then mixing the brine with fly ash and other chemical additives to form a paste suitable for l...
The generation of electricity from coal-fired power plants continue to be a mainstream approach. It is estimated that about 107 million tons of coal combustion residuals (CCRs) were generated in 2017 in the US (ACAA 2018). This equal amount of CCR...
Highway networks represent a type of linear land use crossing streams and sensitive water bodies. Stormwater runoff generated from highway surface has long received much attention due to the presence of a variety of contaminants, such as sediments...
