Vertical cutoff walls have been widely employed for groundwater control and in situ containment of subsurface pollutants. The traditional cutoff wall materials are usually highly susceptible to dry–wet cycles due to precipitation, drought, and groundwater fluctuation, leading to cracking or even disintegration. This study adopted sodium bentonite (NaB) to enhance the …

Aquaculture species will usually die quickly if the pH is less than 4 or greater than 11 (Table 1). Most species can tolerate a pH between 6 and 9 fairly well, but they are usually stressed by pH outside this range resulting in less growth and greater susceptibility to disease. The optimum pH for most species is between 7 and 8.5.

Bentonite, however, has been shown to aid in the restoration of biological functions in drought-affected soils. Bentonite's function as a soil moisture retainer is an important consideration. Bentonite acts as a reservoir, trapping water within its layers due to its high water-holding capacity and ability to form a gel-like structure.
