Evaluation of water agressiveness and corrosiveness towards lead plumbing in teh drinking water distribution system of the City of London.

High level of lead in drinking water can pose a significant health risk to public. The major source of lead in drinking water is known as a leaching from lead bearing plumbing materials used in drinking water system. The leaching of lead can be affected by both the age of the lead bearing materials and the water characteristics. With time, soluble lead ion (Pb2+) may form lead solid forms such as PbCO3, Pb(OH)2(CO3)2, PbO, and PbO2, which reduces the leaching of lead by forming passivating layer. However, the change of water treatment process can affect the stability of the solid phases and cause the increase of lead level in drinking water. The goal of this project is to investigate the stability of the corrosion scale with different water quality parameters in order to better understand the impact of the change of water treatment process on the lead level in drinking water.

Personal Background

Eun Jung completed her Bachelor’s degree in Environmental Engineering in 2000 from University of Seoul in South Korea. She studied environmental analytical chemistry during M.S. degree in Department of Environmental Science and Engineering at Pohang University of Science and Technology in South Korea. She analyzed persistent organic pollutants (POPs) such as dioxins (PCDD/Fs), PCBs, and PAHs in various environmental media and evaluated their distribution and behavior in the environment. She has got her Ph.D. degree in Department of Civil Engineering majoring Environmental Engineering at Texas A&M University-College Station, TX in U.S. in 2008. Her Ph.D. studies were focused on arsenic-pyrite interactions in anoxic environment in order to better understand geochemical cycling of arsenic and predict arsenic fate and transport in the environment. She joined RESTORE in January 2009. Her research interests are on the environmental fate and transport of inorganic and organic pollutants, water chemistry, and nanotechnology.
