Water for the Common Wealth
The Water Systems Lab, led by Dr. Emily Kumpel in Civil and Environmental Engineering at the University of Massachusetts Amherst, is a research group studying water infrastructure, systems, service delivery, and communities across diverse urban and rural contexts.
Our work connects technical measurements of water quality and supply reliability to public health outcomes, regulatory practicies, and policies.
Active and past research locations — click markers for details.
We study water systems across a range of technical and social contexts. Common threads are supply reliability, water quality risk, and equity of access.
More than a billion people receive piped water on an intermittent schedule. We study how the nature and predictability of intermittency shapes household coping strategies, water quality, and health outcomes — through field studies in India, lab-scale experiments, and development of measurement frameworks.
How water quality changes from source through treatment and distribution to the tap. We study microbial quality, disinfection byproducts, and contaminant dynamics in reservoirs and distribution systems, including how wastewater intrusion, intermittency, and pipe materials affect health risk. Also includes lead in schools and lead service line identification.
Much of US water and wastewater infrastructure is unmapped at the parcel level, obscuring service gaps and equity issues. We develop machine learning methods to predict service type at scale, working with state agencies in Massachusetts, California, North Carolina, and the Gulf States.
We examine how storage practices affect microbial water quality and whether interventions can convert storage from a contamination risk into a reliable buffer. Combines lab studies, field work in India, Mexico City, and Kenya, and modeling of household water decisions.
Many small systems face significant challenges meeting Safe Drinking Water Act requirements. We study small system compliance, treatment options, and regulatory data quality — including WASH conditions in rural Alaska where many communities lack running water.
We provide direct technical assistance to water systems and regulators to translate research into practice. Our largest partnership is with the Massachusetts Department of Environmental Protection (MassDEP), supporting SDWA technical assistance, PFAS and emerging contaminants in small and disadvantaged communities, lead in schools and childcare facilities, lead service line inventories, and drinking water well mapping statewide.
Our research integrates field, laboratory, computational, and translational methods.
Culture-based enumeration, short- and long-read sequencing, metagenomics, AMR profiling, pathogen detection, AOC characterization, regulated and unregulated DBP quantification.
Household surveys, water quality sampling (tap and storage), pressure and flow monitoring, longitudinal data collection — from rural Alaska to urban India.
Graph neural networks, random forests, spatial models applied to infrastructure service prediction, compliance risk identification, and large regulatory/geospatial datasets.
Scaled-down physical models of water systems for controlled testing — including a recirculating pipe loop that mimics intermittent distribution systems, and bench-scale household storage models for studying contamination and treatment under realistic supply conditions.
Direct support to water systems and regulators — SDWA compliance, treatment evaluation, data quality — generating research questions grounded in real regulatory challenges.
Structured and semi-structured interviews, surveys, document analysis — used to understand household behaviors, utility decision-making, and equity dimensions of water access.
