Indoor Premise Plumbing: The Relationship Between Water Stagnation, Chlorine Decay, And Total Organic Carbon Levels, Emerson M. Ringger, Andrew J. Whelton, Tolulope Odimayomi, Maryam Salehi

The Summer Undergraduate Research Fellowship (SURF) Symposium

Drinking water safety is critical to the health of populations worldwide, and modern plumbing infrastructure can influence drinking water chemical characteristics. Inside residential and commercial buildings however, water use and contact with different plumbing components can vary. For example, water can endure lengthy stagnation periods and residual disinfectant agents like chlorine can decay, leaving the water vulnerable to microbial growth. Plastic cross-linked polyethylene (PEX) pipes have become popular and have shown to influence water quality. While several studies have been carried out on chemical leaching from PEX piping, none were found that examined the role of pipe diameter in relation …
