Impact/Purpose:
The study will help to develop a more comprehensive understanding of the efficacy of treatability for various water treatment facilities as it relates to their current treatment configuration. The overall occurrence and distribution of these toxics will gain valuable knowledge in the potential for the presence of compromised source waters. Specifically, a further understanding of the presence and influence of HABs will be gained as it relates to the seasonal variability, determination of potential viable analogue indicators for the presence of a bloom and occurrence of these toxins in either the intracellular material or freely dissolved extracellularly. This project will allow the USEPA determine the occurrence and treatability of these compound for determination of regulatory guidance concentration levels, were a number of these compounds are including in the Chemical Candidates List (CCL4) list of for possible regulation. In addition, the results will be used to by the Ohio EPA to evaluate the occurrences of algal toxins in water sources and DWTPs for treatment optimization.
Description:
The propagation of cyanbacterial cells and their toxins were investigated at seven drinking water treatment plants (DWTPs) on Lake Erie were investigated with regards to harmful algal bloom (HAB) toxin concentrations, water quality variations in treatment plant influents, and propagation of cyanobacterial cells and toxins from influent to finished waters.
