The objective of this study was to determine the influence of Schoenoplectus californicus Var. Tatora (totoral) in the removal of heavy metals. The methodology used in the present study was quantitative, descriptive, correlational and explanatory; the research design was sequential and probative. Studies were doing during the dry and flooding season during the period 2013 to 2017 and part of 2018. From the obtained results, the totoral adsorbs heavy metals through leaves and roots; aluminum, iron, arsenic, barium, copper, lead and zinc are mostly adsorbed by the roots (rhizofiltration) and manganese is absorbed mostly by the leaves (phytoextraction). It was shown that totoral is a hyperaccumulating plant of aluminum, iron and lead where 1139, 8560, and 93.8 mg / kg were obtained. The presence of sulphate-reducing bacteria (SRB) at the LChin1 point at a concentration of 115000 cfu / 100mL was determined and 6% of pyrite (FeS2) and 2% of spharelite ((Zn, Fe) S) were determined in the sediments and at the LChin7 point a concentration of 27000 cfu / 100mL was obtained and 2% of pyrite (FeS2) was determined in the sediments. It was concluded that the totoral decreases the concentration of metals by adsorbing on roots and leaves by means of rhizofiltration and phytoextraction mechanisms and sulfate reducing bacteria contribute to the precipitation of heavy metals in the way of sulfides whose concentration depends on the amount of substrate present in the place.
