Elovitz, M., E. Kleiner, C. Impellitteri, W. Gray, A. McFadden, S. Kinslow, S. Mardani, AND S. Yi. Effect of bromide in a surface water intake on the formation of brominated trihalomethanes at a public water system treatment plant.

Impact/Purpose:
Develop & use predictive statistical model to: Estimate the probability of TTHM MCL exceedance for various levels of source water bromide concentration Model the relationship between source water bromide, among other parameters, and THM formation in order to inform treatment plant optimization Potentially inform policy or regulatory actions, such as efforts to establish discharge permit limits using narrative standard and/or water quality criteria
Description:
This project is a collaborative drinking water research study. EPA is evaluating water samples collected by PWS operators in order to investigate relationships between bromide in source water and the formation of brominated DBPs in finished drinking water. This study will include a two year long water sampling period, which began in January 2013. Samples are collected at four locations in the drinking water treatment and distribution process:(1) Source water prior to treatment(2) After filtration(3) Finished water prior to distribution(4) Finished water at the consumer tap at a compliancemonitoring location
