Fibers from the textile industry were found to accumulate in the aquatic biota of the Valsequillo reservoir. Quality indexes demonstrated that waters and sediments in the Puebla City are the most contaminated. The water of this zone reached the classification of strongly contaminated, whereas the sediments showed the most accumulation/enrichment of major and trace elements of the riverine zones. The main pathologies found in humans were gastrointestinal diseases, whereas children living in vulnerable zones showed elevated levels of cancer biomarkers. Studies have indicated a high risk of suffering cancerous diseases in children that consume contaminated groundwater and high risks for developing non-cancerous diseases in adults working with river-irrigated soils and children consuming milk with high content of river-derived Arsenic.This study examines the use of organic petrology techniques to quantify the amount of coal and carbonaceous combustion by-products (i.e., coke, coal tar/pitch, cenospheres) in sediments taken from the Kinnickinnic River adjacent to the former site of the Milwaukee Solvay Coke and Gas Company. These materials are of concern as contaminants like polycyclic aromatic hydrocarbons (PAHs) are known to readily adsorb to coal and combustion byproducts. Kinnickinnic River sediment samples (n = 36) ranging in depth (1-11 ft.) were collected from eight core locations to quantify and characterize carbonaceous material in the sediments. To determine the amount (vol%) of organic particulates, U.S. Geological Survey (USGS) modified the existing ASTM D2799 using the following categories coal, coke, coal tar/pitch, inertinite organics, plant material, cenospheres, and mineral matter. Coal fragments were subdivided by rank using vitrinite reflectance (Ro, %) and organic components we
