The method of phytoremediation using Eichhornia crassipes plants was able to overcome the problem of cadmium (Cd) heavy metal pollution. This study aims to analyze the population of bacteria in Cd phytoremediation in groundwater using E. crassipes . The treatment in the study included T1 of 3 mg/L, T2 of 7 mg/L and T3 of 9 mg/L. The parameters observed were Cd concentration, a total of bacteria numbers, change in pH and total suspended solids (TSS). Based on the results of the study, the T1 treatment was the best absorbs of Cd in groundwater when using E. crassipes was 82%. It was the highest compared to other treatments which presented T2 of 65% and T3 of 73%. The highest bacteria population in T1 treatment. For pH and TSS, all treatments on the 12 th day relatively of similar. In addition, this study also produced five types of isolates based on the results of characterization, including M1, M2, M3, M4, and M5. This shows that the E. crassipes will be inhibited from absorbing Cd at high concentrations, also affecting bacteria growth.
