Edwards Brian J. Love James M. Tanko, April 2, Blacksburg, Virginia. Abstract: While more than years of research has focused on removing acute and chronic health threats from water, substantially less study has focused on potable water infrastructure and water quality deterioration, monitoring technologies, and relationships between water taste and consumer health.

These knowledge—gaps also prevent infrastructure managers from producing drinking water that optimizes mineral content for both water taste and health benefits, and employing a monitoring tool capable of immediately detecting water contamination or equipment failures. Research was conducted to address these challenges using analytical chemistry, environmental engineering, food science, polymer chemistry, public health, and material science principles.

This work was enhanced by collaborations with sixteen American water utilities and the National Institute for Standards and Technology. Research results are unique and provide important scientific contributions to the public health, potable water, and material science industries.

Outcomes of this work have domestic and global significance, and if engaged, can greatly improve public health protection, potable water infrastructure operations, water quality, sustainability, and regulation.

The odour of water in contact with plastic pipes was assessed according to the quantitative threshold odour number TON concept. In addition, a range of esters, aldehydes, ketones, aromatic hydrocarbons and terpenoids were identified as migration products from HDPE pipes. Several of the migrated VOC were not identified. Migration tests of PVC pipes revealed few volatile migrants in the test samples and no significant odour of the test water.

Whelton, Ph. Dietrich, Ph. Gallagher, Ph. Variations in PE pipe density 0. While numerically these differences seem minor, results show that slight material differences have a notable effect on contaminant diffusivity and solubility. Nonpolar contaminant diffusivity and solubility were best predicted by bulk density. For all materials, dipole moment and Log Kow were good predictors of contaminant fate and molecular volume was only useful for predicting diffusivity and solubility values for haloalkane and nonpolar aromatic contaminants.

Gallagher, and Andrea M. Journal of Environmental Engineering , Online publication date: 1-Feb Abstract: A model was developed and validated for predicting solubility and diffusion coefficients for contaminants permeating polyethylene PE materials used for water pipes and geomembranes.

Physical and chemical properties of the contaminants and PEs were included as variables in the model. Tree regression was used to select variables, and multiple linear regression was used to develop predictive equations for contaminant diffusivity and solubility in PE.

Organic contaminant properties, especially dipole moment and octanol-water partition coefficient, had greater predictive capability than PE properties. Model coefficients changed slightly between new PE materials and chlorine-aged PE, but these changes were not statistically significant. Good agreement was demonstrated between model predictions and measured data from an independent data set. These results provide guidance for material selection for both water pipes and geomembranes and assessing contamination potential.

Dietrich, and Daniel L. Journal of Environmental Engineering , Online publication date: 1-Jul Abstract: The aim of this work was to determine if the aging of polyethylene HDPE, PEX-A and PEX-B water pipes by exposure to chlorinated water altered polar and nonpolar contaminant diffusivity and solubility by analyzing new, laboratory-aged, and exhumed water-distribution system polyethylene PE pipes.

After days of aging in pH 6. Toluene and trichloromethane diffusivity and solubility values for 7- to year-old buried water utility pipes were similar to values for new and laboratory-aged HDPE-based materials. Because chlorinated water exposure alters how polar contaminants interact with aged PE pipes, results of this work should be considered in future health risk assessments, water quality modeling, pipe performance, and service-life considerations.

Contaminant migration from polymer pipes into drinking water is a growing concern in the United States and environmental engineers are evaluating the role of these materials on water quality, system operation, and regulatory compliance. To aid these efforts and serve as a source of background information, this paper critically reviews available literature on polymeric potable water pipes in use, known contaminants released from in—service and new piping, their perceived sources, and outlines future challenges in the U.
