Geosynthetic clay liners (GCLs) with sodium (Na) bentonite clay are effective hydraulic barriers with extremely low hydraulic conductivity (≈1x10 -9 cm/s) when the bentonite hydrates and swells to produce a uniform layer with very small and tortuous pores. High-ionic strength solutions and solutions with extreme pH (11<pH<3) can limit bentonite swelling, and preclude low hydraulic conductivity. Various polymers have been explored as bentonite amendments to improve chemical compatibility of GCLs… CONTINUE READING
