Abstract Title

Metal Content of Kent State Stormwaters

Abstract

Metals like zinc and lead are toxic in small quantities and can only be removed from water with expensive processes. Kent State University is considered a municipality by the EPA and as such is responsible for managing the quantity and quality of its stormwater. There are many urban sources of metals, including brake dust from cars, roof flashing, various galvanized metal products, and storm grates. We collected over 170 samples during storm events and measured particulate Fe, Zn, Ni, Pb, Mn, and Cu in stormwater draining portions of the KSU campus. Median metal concentrations in stormwater were 1655 ug Fe/L, 81 ug Mn/L, 44 ug Zn/L, 3.8 ug Cu/L, 1.85 ug Ni/L, 4.6 ug Pb/L, but maximum concentrations ranged from 5–40 times higher than medians. Zn and Pb both saw spikes in particulate concentrations above the probable effect concentration. This means there is a strong chance for the particles to cause harm to biota that come into contact with the stormwater sediment. These results will assist in future studies to further the understanding of metal behavior in stormwater.
