A state-by-state comparison of policies that protect private well users.

BACKGROUND: While the Safe Drinking Water Act allows states and localities to adopt stronger protections for drinking water, state and local requirements concerning private drinking water wells vary dramatically and often do not provide necessary protections for residents who rely on well water. OBJECTIVE: This paper inventories ten types of policies including laws, regulations, programs, and activities that states have adopted or partaken in to encourage safe drinking water for residential well owners. METHODS: To identify categories of private well protections, we conducted a preliminary internet search with key search terms to create an initial list of 10 categories of laws, regulations, programs, and activities (collectively referred to as "policies") that states have taken to protect residential well water quality. To have a private well safety category present, the law, regulation, program, or activity must fit within the scope of the ten classifications. To limit the breadth of our search, we excluded local and county protections, as well as activities by non-governmental organizations. We also excluded basic construction standards for new wells and licensing standards for well drillers, both of which are covered under a previous study. We conducted an additional internet search to complete a comprehensive review of each state and category and to validate our previous findings. In addition to this internet search, we completed phone and email outreach to the state agencies implementing the well safety categories identified in our internet search to confirm our results. RESULTS: The results indicate a wide range of state-based well water protections. The number of residential well water protections present in each state ranged from 8 policies in Iowa, Kentucky, and Maine to 1 policy in Oklahoma, with a median of 5 policies across the 50 states. IMPACT: This paper examines protections that states have implemented to safeguard residential well water quality and to protect the health of people who rely on well water. This research reviews state-level regulations, laws, and programs, as opposed to local, municipal, county-level, or quasi-governmental protections for residential well owners. Residential well policies were examined across ten categories. Without any protections at the federal level, this research reveals gaps in state regulation and demonstrates the need for broader adoption of comprehensive state-level policies to better protect residential well owners from drinking water contaminants and their associated public health impacts.

US drinking water quality: exposure risk profiles for seven legacy and emerging contaminants.

BACKGROUND: Advances in drinking water infrastructure and treatment throughout the 20th and early 21st century dramatically improved water reliability and quality in the United States (US) and other parts of the world. However, numerous chemical contaminants from a range of anthropogenic and natural sources continue to pose chronic health concerns, even in countries with established drinking water regulations, such as the US. OBJECTIVE/METHODS: In this review, we summarize exposure risk profiles and health effects for seven legacy and emerging drinking water contaminants or contaminant groups: arsenic, disinfection by-products, fracking-related substances, lead, nitrate, per- and polyfluorinated alkyl substances (PFAS) and uranium. We begin with an overview of US public water systems, and US and global drinking water regulation. We end with a summary of cross-cutting challenges that burden US drinking water systems: aging and deteriorated water infrastructure, vulnerabilities for children in school and childcare facilities, climate change, disparities in access to safe and reliable drinking water, uneven enforcement of drinking water standards, inadequate health assessments, large numbers of chemicals within a class, a preponderance of small water systems, and issues facing US Indigenous communities. RESULTS: Research and data on US drinking water contamination show that exposure profiles, health risks, and water quality reliability issues vary widely across populations, geographically and by contaminant. Factors include water source, local and regional features, aging water infrastructure, industrial or commercial activities, and social determinants. Understanding the risk profiles of different drinking water contaminants is necessary for anticipating local and general problems, ascertaining the state of drinking water resources, and developing mitigation strategies. IMPACT STATEMENT: Drinking water contamination is widespread, even in the US. Exposure risk profiles vary by contaminant. Understanding the risk profiles of different drinking water contaminants is necessary for anticipating local and general public health problems, ascertaining the state of drinking water resources, and developing mitigation strategies.

Local Measures to Curb Dollar Store Growth: A Policy Scan.

In recent years, advocates have expressed concern about the exponential growth of dollar stores in low-income communities, given their limited stock of healthy foods, and several municipalities in the U.S. have passed novel policies to curb the proliferation of these stores. The purpose of this scan is to create a legal database to inform future healthy retail policies and programs. Legal mapping methods were used to identify local policies aimed at moderating dollar store proliferation. A search yielded 25 policies that met the inclusion criteria, all enacted between 2018 and 2020. Recent policies aiming to slow local dollar store growth were mostly passed in low-income communities of color. All identified policies were passed in either the Midwest or South. The majority of municipalities that passed the policies had populations where more than half of residents identified as non-Hispanic Black or Hispanic and where the poverty rate was greater than the national average. Twelve (48%) municipalities imposed temporary moratoria halting new dollar stores from opening, and ten (40%) banned new construction within a specified distance of an existing dollar store. Key themes identified from analysis of policies' purpose statements included increasing healthy food availability, diversifying local businesses, and improving community safety. These findings may be useful to leaders in other communities seeking to potentially moderate the impact of dollar stores on community health, as well as researchers and policy makers seeking to evaluate the efficacy of existing policies.
