Conventional drinking water treatment generally requires maintenance of a disinfectant residual, most commonly free or combined chlorine. Since the discovery of disinfection byproducts (DBPs), utilities have relied on a broad range of water quality parameters to help them achieve compliance with DBP regulations. Most notably, dissolved organic carbon (DOC) and ultraviolet absorbance at 254 nm (UV254) have been used to assess DBP precursor levels in near-real time. These are often compared to actual system DBP concentrations or to results from laboratory DBP precursor tests resulting in a site-specific precursor-DBP model. The DOC or UV254 models are often inaccurate, requiring re-calibration, …

Metal contamination in drinking water, especially heavy metals such as lead, and corrosion issues, pose a threat to human health and have received increasing attention in recent years. This study reports on the results of ‘The Massachusetts Assistance Program for Lead in School Drinking Water’ and provides a better understanding of the dynamics of sampling protocols, premise plumbing and their influence on lead and copper concentrations. ‘The Massachusetts Assistance Program for Lead in School Drinking Water’ that was announced in April 2016, implemented tap-based water sampling for lead and copper at K-12 public schools and Early Education and Childcare centers …

Developing A Toolkit For Citizen Scientists' Evaluation Of Drinking Water Quality, Leighann D'Andrea
Environmental & Water Resources Engineering Masters Projects
This project evaluated tools for citizen science by assessing the potential to monitor drinking water quality at home with commercially sold, or off the shelf, test kits. The first objective was to compare the results of off the shelf test kits with laboratory-obtained values as performed in a controlled environment by trained laboratory personnel. The second objective was to provide potential citizen scientists with a selection of test kits to determine if they could successfully use the kits. These two objectives contributed to the end goal of understanding whether test kits on the market existed that could be used by …

Riparian wetlands can serve as nature-based infrastructure that slow the rapid movement of water during high flow events. As the recurrence of high flow events increases due to global climate change, an improved understanding of the potential of wetland landscapes to provide flood mitigation is needed. This research addresses both the impacts of climate change and land cover on extreme flow events in the Otter Creek watershed in Vermont. The upstream portion of the basin is modeled with the Soil and Water Assessment Tool (SWAT) to investigate the impacts of climate change on extreme flow events. A Hydrologic Engineering Center's …
