A series of countylevel spatial econometric models showed positive economic development associated with water infrastructure spending in rural America. However, these benefits are unequally distributed among ethnoracial populations in interaction models. The United States can no longer afford to put off significant investments in drinking water and wastewater infrastructure. The allocation of US$50 billion to drinking and wastewater infrastructure through the passage of the 2021 Infrastructure Investment and Jobs Act is encouraging. However, this is hardly enough. In 2012, the American Water Works Association estimated that more than US$1 trillion was required 1. Furthermore, a consistent finding is that communities with a higher proportion of racial/ethnic minorities and low socioeconomic status are more likely to be served by a water utility that incurs drinking water violations 2-4. The Crating of the United States drinking water systems bestowed by the 2021 American society of civil engineers reflects a neglected, disinvestment, and insufficient investment to ensure a safe drinking water supply for all. Notable reasons for this rating include failure to repair, replace, and upgrade water pipe networks, and the report card stresses the need for more assistance in rural areas. The technical, managerial, and financial capacity challenges of operating water utilities in rural areas are often due to constrained resources. The water sector industry and local governments continue to express serious concerns about the decreasing population in rural America. Eventually, less population means a shrinking tax base. Over the past decade, rural America has become more racially and ethnically diverse; however, rural communities continue to experience a net loss in population. This population shift translates to rural communities throughout the United States not being able to afford or address aging infrastructure and keep up with the costs of treating raw water to ensure it is safe to drink (that is, meets regulatory standards). Now writing in Nature Water, Tom Mueller and Stephen Gasteyer 5 provide insights into whether investing in water infrastructure results in improved economic development in rural areas. The findings between drinking water infrastructure expenditures and economic development impact show a positive relationship 5 , albeit the rate is inconsistent. Few studies have previously examined this relationship in rural communities. Mueller and Gasteyer ground their study in the framework of community capitals 6 and hypothesize that "local government investment in water infrastructure will have a significant positive relationship with economic development in rural counties." This framework allows us to see the interconnectedness

To investigate the impacts of not being connected to a community water system, I surveyed households in El Paso County colonias that were not connected to a community water system (household n = 75, individual n= 293) and households that were connected to a community water system (household n = 75, individual n= 320). I conducted 150 door-to-door surveys and tested water samples from each household for free residual chlorine level, turbidity level, presence of total coliforms and E.coli during November 19, 2011 through January 27, 2012. Using this data, I applied an environmental and economic injustice approach to analyze the relationship between socio-demographics, water costs, water quality, water storage practices, sanitation, and health outcomes using descriptive statistics, independent samples differences of means t-test, z-t...

In the United States, the Safe Drinking Water Information System (SDWIS) database records the occurrence of a drinking water violation regulation in public water systems. A notable shortcoming of SDWIS is the lack of the contaminant concentration level about the allowable maximum contaminant threshold. In this study, we take advantage of both the SDWIS violation database and the contaminants sampling database at the state level to examine the drinking water quality of all kinds of drinking water systems in detail. We obtained sampling data (i.e., the concentration level of contaminants) of public water systems (PWSs) in Tennessee and explored the statistical distribution of contaminant concentration data in relation to the enforceable maximum regulatory contaminant level). We use both SDWIS violation records and actual concentrations of contaminants from the sampling data to study the factors th...

Nearly 30% of the United States population obtained their water from community water systems that did not meet federal regulations in 2019. Given the heavy interactions between society and drinking water quality, this study integrates social constructionism, environmental injustice, and sociohydrological systems to evaluate local awareness of drinking water quality issues. By employing text analytics, we explore potential drivers of regional water quality narratives within 25 local news sources across the United States. Specifically, we assess the relationship between printed local newspapers and water quality violations in communities as well as the influence of social, political, and economic factors on the coverage of drinking water quality issues. Results suggest that the volume and/or frequency of local drinking water violations is not directly reflected in local news coverage. Additionally, news coverage varied across sociodemographic features, with a negative relationship between Hispanic populations and news coverage of Lead and Copper Rule, and a positive relationship among non-Hispanic white populations. These findings extend current understanding of variations in local narratives to consider nuances of water quality issues and indicate opportunities for increasing equity in environmental risk communication.

A case-control study was conducted with records from population-based registries in New Mexico. Cases were women diagnosed with cervical cancer in 2006-2016, obtained from the Tumor Registry. Five controls per case from the New Mexico HPV Pap Registry were matched to cases by sex, age and place of residence. Dates and results of all cervical screening and diagnostic tests since 2006 were identified from the pap registry. We estimated the odds ratio of nonlocalized (Stage II+) and localized (Stage I) cervical cancer associated with attending screening in the 3 years prior to case-diagnosis compared to women not screened in 5 years. Of 876 cases, 527 were aged 25-64 years with ≥3 years of potential screening data. Only 38% of cases and 61% of controls attended screening in a 3-year period. Women screened in the 3 years prior to diagnosis had 83% lower risk of nonlocalized cancer (odds ratio [OR] = 0.17, 95% CI: 0.12-0.24) and 48% lower odds of localized cancer (OR = 0.52, 95% CI: 0.38-0.72), compared to women not screened in the 5 years prior to diagnosis. Women remained at low risk of nonlocalized cancer for 3.5-5 years after a negative screen compared to women with no negative screens in the 5 years prior to diagnosis. Routine cervical screening is effective at preventing localized and nonlocalized cervical cancers; 3 yearly screening prevents 83% of nonlocalized cancers, with no additional benefit of more frequent screening. Increasing screening coverage remains essential to further reduce cervical cancer incidence.

The quality of the geocode can vary dramatically depending on several variables, including incorrect input address data, missing address components, and spelling mistakes. A dataset with a considerable number of geocoding inaccuracies can potentially result in an imprecise analysis and invalid conclusions. There has been little quantitative analysis of the amount of effort (i.e. time) to perform geocoding correction, and how such correction could improve geocode quality type. This study used a low-cost and easy to implement method to improve geocode quality type of an input database (i.e. addresses to be matched) through the processes of manual geocode intervention, and it assessed the amount of effort to manually correct inaccurate geocodes, reported the resulting match rate improvement between the ...

Geographic accessibility, stratified by rural and nonrural areas, to necessary services across the cervical cancer continuum of preventive care is largely unknown. Health care facility data for New Mexico (2010-2012) was provided by the New Mexico Human Papillomavirus Pap Registry (NMHPVPR), the first population-based statewide cervical cancer screening registry in the United States. Travel distance and time between the population-weighted census tract centroid to the nearest facility providing screening, diagnostic, and excisional treatment services were examined using proximity analysis by rural and nonrural census tracts. Mann-Whitney test (P < .05) was used to determine if differences were significant and Cohen's r to measure effect. Across all cervic...

The model is designed to employ low-cost secondary data, and it is rooted in a perspective that merges normative environmental justice concerns with theoretical grounding in health inequalities. Since the model employs International Classification of Diseases, Ninth Revision Clinical Modification (ICD-9-CM) disease codes, it is transferable to other contexts, appropriate for use across spatial scales, and suitable for comparative analyses. We demonstrate the utility of the model through analysis of 2008-2010 hospitalization discharge data at state and county levels in Texas (USA). We identified several disease categories (i.e., cardiovascular, gastrointestinal, heat-related, and respiratory) associated with climate change, and then selected corresponding ICD-9 codes with the highest hospitalization counts for further analyses. Selected diseases include ischemic heart disease, diarrhea, heat exhaustion/cramps/stroke/syncope, and asthma. Cardiovascular disease ranked first among the general categories of diseases for age-adjusted hospital admission rate (5286.37 per 100,000). In terms of specific selected diseases (per 100,000 population), asthma ranked first (517.51), followed by ischemic heart disease (195.20), diarrhea (75.35), and heat exhaustion/cramps/stroke/syncope (7.81). Charges associated with the selected diseases over the 3-year period amounted to US$5.6 billion. Blacks were disproportionately burdened by the selected diseases in comparison to non-Hispanic whites, while Hispanics were not. Spatial distributions of the selected disease rates revealed geographic zones of disproportionate risk. Based upon a downscaled regional climate-change projection model, we estimate a &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;5% increase in the incidence and treatment costs of asthma attributable to climate change between the baseline and 2040-2050 in Texas. Additionally, the inequalities described here will be accentuated, with blacks facing amplified health disparities in the future. These predicted trends raise both intergenerational and distributional climate health justice concerns.

To date, researchers have not incorporated insurance status (an access to health care variable) in their models although access to care likely has an important association with the probability of health effects due to environmental exposures. As such, insurance status represents an important variable within spatial EJ studies focused on health, and the lack of spatially explicit access to care data is a critical limitation in the field. As a solution, we offer a method of using uninsured appendicitis cases, acquired secondarily from state hospital admissions data, to estimate rates of uninsurance at the zip-code level. We apply the technique to explore relationships between cancer risk from hazardous air pollutants and estimated rates of uninsurance, a previously unexplored phenomenon. Then, we compare the uninsurance findings to those related to poverty to illustrate how uninsurance, as a variable, compares to a more traditional socioeconomic predictor used in EJ studies. The relationship between cancer risk from hazardous air pollutants and uninsurance is weaker than the relationship between risk and poverty, but both are statistically significant. As such, we conclude with a discussion of the importance of considering insurance status in spatial studies of EJ focused on health.

After using a relative risk method to illustrate the characteristics of neighborhoods at risk for waterborne diseases based on lack of plumbing, we ran spatial regression models predicting lack of plumbing to uncover similarities and differences between the two cities. In terms of similarities, lower mean education and higher proportions of young children were associated with lacking plumbing in both cities. Lower population density and higher proportions of female-headed households were significant only in Juárez, and proportion renting was negatively associated with lacking plumbing in Juárez, but positively associated in El Paso, pointing to differences in socio-spatial structure between the cities. In framing this issue as an environmental injustice, this study draws attention of the existence of households lacking plumbing in the United States and Mexico.

Results indicate that Hispanics' ethnic status interacts with class, gender and age status to amplify disproportionate risk. In contrast, results indicate that non-Hispanic whiteness attenuates cancer risk disparities associated with class, gender and age status. Findings suggest that a system of white-Anglo privilege shapes the way in which race/ethnicity articulates with other dimensions of inequality to create unequal cancer risks from air toxics.
