Pharmaceuticals, perfluorosurfactants, and other organic wastewater compounds in public drinking water wells in a shallow sand and gravel aquifer. Epidemiology. Smaller water systems may have fewer financial and technical resources to address contamination issues when they arise [1], and the cost of water treatment per household is considerably higher for smaller systems because of a lack of economies of scale [9]. Manage cookies/Do not sell my data we use in the preference centre. Schaider LA, Ackerman JM, Rudel RA. Lubin JH, Colt JS, Camann D, Davis S, Cerhan JR, Severson RK, et al. Because purchasing systems were not included in our analysis, it was important that the data for each wholesaler included all of the cities that purchase its water in order to best characterize the population served by each CWS. Balazs CL, Morello-Frosch R, Hubbard AE, Ray I. The likelihood of studies finding environmental justice associations with the siting of hazardous waste facilities strongly depends on the unit of analysis (e.g., county, census block) and overall scope (e.g., state, national); studies with a small unit of analysis and large scope were most likely to find significant associations [10]. While the Rockefeller donation provided money 20102014 American Community Survey Data Profiles, 5-year estimates. Int J Cancer. We assessed whether our results depended on geographic region or on the spatial resolution of the demographic data. As a result of these modifications, we expanded data on the cities served for 1245 wholesale systems (174 of which lacked any city served data prior to considering purchased water systems) and adjusted the system size for 220 wholesale systems. Environ Pollut. Multiple imputation for nonresponse in surveys. 2014. In communities of color, institutional barriers in local planning and zoning practices may lead to lower rates of drinking water and wastewater infrastructure improvement [13].

Lower Yakima Valley Groundwater Quality: Preliminary assessment and recommendations document. In addition, such supplies may have diminished technical, managerial, and financial (TMF) capacity to properly manage their drinking water, so these systems may lack the resources necessary to comply with testing requirements. J Environ Health. J Environ Plan Manag. The extent of cropland coverage and livestock production had significant but small associations with nitrate concentrations, while a one-unit increase in the percent of land area used as cropland had a more substantial effect (3.3% increase, 95% CI: 3.0, 3.7%) on the likelihood that a CWS had high nitrate. Previous studies have found inconsistent relationships between system size and contaminant violations. Cite this article. When problems are identified, small systems with limited TMF may struggle to address these problems, such as through the installation of new treatment systems or development of better protected sources [1]. The West and Midwest had the highest proportions of high nitrate systems (5mg/L) and the highest 95th percentile nitrate concentrations, while the South had the lowest (Table 1). County-level data on agricultural parameters can be downloaded from the U.S. Department of Agricultures 2012 Census of Agriculture website (https://www.agcensus.usda.gov/Publications/2012/Online_Resources/Ag_Census_Web_Maps/Data_download/index.php).

We developed a protocol to identify outliers that were either misreported or misevaluated based on the average difference between each sample result and other samples from that system. Private wells are shallower than public wells, and shallow wells are more vulnerable to nitrate contamination [49]. By contacting state agencies, we were able to supplement SDWIS data for 1509 CWSs in three states; however, 13 states rarely or never record information in the cities served field (Fig. Vulnerability of shallow groundwater and drinking-water wells to nitrate in the United States. Because we lacked information about flow volumes from multiple sources within CWSs, we weighted all samples collected for each CWS equally. Extent of agricultural land use and reliance on groundwater sources were significantly associated with nitrate. Delpla I, Benmarhnia T, Lebel A, Levallois P, Rodriguez MJ. Environmental justice associations with drinking water have not been consistently observed, and may depend on the spatial scope and individual contaminants studied. Terms and Conditions, Drinking water quality is regulated in the United States under the Safe Drinking Water Act (SDWA), which establishes national monitoring and reporting requirements and maximum contaminant levels (MCLs) for 88 contaminants. SDWIS provided information in the counties served field for >99% of CWSs (n=41,781), but only 48.1% of CWSs reported information in the cities served field (n=20,267). Using the same multiple imputation approach, systems were categorized as high nitrate if their estimated system average was 5mg/L, a level associated with adverse health outcomes in some epidemiological studies, and as low nitrate otherwise. The International Agency for Research on Cancer classified ingested nitrate or nitrite under conditions that result in endogenous nitrosation as a probable human carcinogen (Group 2A) [31]. To evaluate the effect of the spatial scale of the demographic data, we also repeated our analyses using demographic data representing the city or cities served by each CWS. 2012 Census of agriculture, Agriculture Census Web Maps 2012. https://www.agcensus.usda.gov/Publications/2012/Online_Resources/Ag_Census_Web_Maps/Overview/. Race, ethnicity, and at least one poverty indicator were retained in all models, and other covariates were retained if they were significantly associated with the outcome (p<0.05) or if removing them from the model changed the effect estimates for other covariates by more than 10%. These factors are especially apparent in unincorporated areas, which have no tax base and lie outside of the municipal boundaries overseen by county or state entities. 2016;106(2):28390. For instance, if a CWS served five cities, then the proportion of Hispanic residents associated with that CWS was calculated as an average of the proportion of Hispanic residents in each of the five cities, weighted by each citys population. Epidemiological evidence for adverse health effects associated with consumption of drinking water above 5mg/L nitrate raise concerns about increased risk in people exposed at this level and support a re-evaluation of the federal nitrate standard. WebNative Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the indigenous peoples of the United States, including Hawaii and territories of the United States, as well as Northern Mexico and Canada and other times just the mainland United States. 2013;122:5864. Notably, the city served and county served fields are not checked for consistency at a national level, so SDWIS entries are prone to local (rather than official) naming conventions and typographical errors. Over 90% of the CWSs in our sample served 10,000 people (very small, small, and medium size systems); these systems provided water to less than 20% of the population served by public water supplies overall. Additionally, after adjusting for demographic and land use parameters, very small systems were more likely to have high nitrate compared to small and medium sized systems. Figure S1 Number of community water systems compiled from SDWIS and subsequently used for regression analyses. In these regionally stratified models using county-level demographics, no single feature had the same impact on system average nitrate concentrations across all four U.S. regions (Table5). The majority of estimated annual mean nitrate concentrations were below 1mg/L for all system sizes, regions, and source water types. Table S5 Spearman correlation matrix for county-level predictors, South systems. Among environmental justice indicators, race and ethnicity differed among regions and across system sizes, while wealth-related factors were less variable. Espejo-Herrera N, Gracia-Lavedan E, Boldo E, Aragones N, Perez-Gomez B, Pollan M, et al. Switzer D, Teodoro MP, Karasik S. The human capital resource challenge: recognizing and overcoming small utility workforce obstacles. As with race/ethnicity, wealth can be expected to relate to levels of contamination in two ways: proximity to pollution sources and ability to treat contaminated source water. Nitrate in drinking water and risk of death from bladder cancer: an ecological case control study in Taiwan. As part of the original implementation of the SDWA in 1974, the U.S. EPA established a nitrate MCL of 10mg/L NO3-N (45mg/L NO3) based on case studies of methemoglobinemia in infants who consumed formula mixed with water containing nitrate [18]. Furthermore, the demographics of the areas associated with the administrative addresses often varied substantially from the demographics of each water systems cities served (Additionalfile1: Table S1). Switzer D, Teodoro MP. Data used to estimate demographic characteristics can be downloaded using the U.S. Census Bureaus American Fact Finder (https://factfinder.census.gov/). A population-based case-control study of drinking-water nitrate and congenital anomalies using geographic information systems (GIS) to develop individual-level exposure estimates. These can relate to both internal factors (diminished ability to raise rates for customers) and external factors (ability to apply for loans). Of the 42,114 CWSs that did not purchase water from another system and were active between 2010 and 2014, we were able to match 39,466 CWSs to both a complete county-level demographic profile and at least one nitrate measurement from that time period (Additional file 1: Figure S1). (PDF6544 kb), Data glossary for U.S. community water systems. In 2013, 9800 public water systems, serving 26.5 million Americans, had violations of health-based standards [1]. The lead crisis in Flint, Michigan, has sparked concern about broader socioeconomic disparities in exposures to drinking water contaminants. Colorectal cancer risk and nitrate exposure through drinking water and diet. 2010;28(2):26474. Finally, to determine whether differences between the county-level and city-level results were more dependent on the scope (geographic area considered in the analysis) or scale (resolution of the city vs. county demographics), we developed an intermediate third model using county-level demographics for only those CWSs included in our city-level analysis. All county served names provided by SDWIS were matched to Census Bureau records in this manner. More Rates of poverty and home ownership were marginally, albeit significantly, lower in counties served by systems with higher nitrate concentrations. Understanding the extent of current exposures, particularly among vulnerable subpopulations, is critical for developing effective strategies to reduce exposures in these communities. Inorganic Chemical Sampling and Analytical Requirements. Dietary nitrate and nitrite and the risk of thyroid cancer in the NIH-AARP diet and health study. We obtained race, ethnicity, poverty, and home ownership information (20102014 five-year estimates) and the proportion of households in urbanized areas (2010 estimates) from the U.S. Census Bureau for each county, census-designated place, and county subdivision in the 50U.S. states [38, 39]. Table S6 Spearman correlation matrix for county-level predictors, West systems. Scales of justice: is there a geographic bias in environmental equity analysis? I. OVERVIEW Title VII of the Civil Rights Act of 1964, as amended, protects applicants and employees from employment discrimination based on their race, color, religion, sex, national origin, opposition to practices made unlawful by Title VII, or participation in Title VII proceedings. By contrast, the percent of residents living in poverty and percent African American residents were both inversely associated with nitrate. The ranges of these five-year system average intervals were generally narrow: 67.3% of system averages had a range0.2mg/L, 99.8% had a range1mg/L, and 0.2% (91 systems) had a system average interval range>1mg/L. Get FREE EXCLUSIVE insider tips on how to 1), so a substantial portion (49.4%) of CWSs were not included in this city-level analysis. Communities with higher proportions of minority residents, particularly those who are non-native English speakers, may have less political influence and may be disenfranchised from political and budgetary decision-making processes [11], and therefore may have fewer resources to install new treatment technology or develop new source waters in response to contamination. While >99% of CWSs do not exceed the nitrate MCL of 10mg/L, 5.6 million Americans are served by CWSs with nitrate concentrations above 5mg/L. See world news photos and videos at ABCNews.com Census-designated places were prioritized in all other U.S. regions, where county subdivision matching was infrequent. Such factors may be related to wealth to the extent that they are driven by economic activity. Virtual: All participants attend for the duration of the project using an online platform. Taken together, these results suggest that larger systems have higher nitrate on average, but that very small systems are more likely than other system sizes to have nitrate concentrations at the high end of the distribution. Since agricultural data were only available at the county level, our analyses using city-level demographics included agricultural variables corresponding to the counties served by each system. In light of growing epidemiological evidence for nitrate health effects below the MCL and evidence on a local level for socioeconomic disparities in nitrate exposure, our study was designed to evaluate whether nitrate concentrations are elevated in public water supplies that serve communities with higher proportions of low-income and/or minority residents. LS prepared the dataset and conducted the studys statistical analysis. Indeed, a nationwide analysis indicated that small CWSs were more likely to have management-related SDWA violations [12]. The proportion of high nitrate CWSs was nearly four times higher for systems that rely on groundwater sources compared to CWSs that rely on surface water sources, and the 95th percentile concentration for groundwater systems was more than 2mg/L higher. In the binary model, very small systems had a greater likelihood of high nitrate compared to small and medium systems. Environmental justice implications of arsenic contamination in California's San Joaquin Valley: a cross-sectional, cluster-design examining exposure and compliance in community drinking water systems. Datasets gathered from SDWIS describing the characteristics of community water systems in the U.S. (including those features needed to associate wholesalers with the systems that purchase their water) are available for download as Additional files. Nitrate is commonly found in drinking water, especially in agricultural regions, and epidemiological evidence suggests elevated risk of cancer and birth defects at levels below U.S. EPAs drinking water standard (10mg/L NO3-N).

J Occup Environ Med. Discover our premier periodical database Gale Academic OneFile. By contrast, high nitrate CWSs served less than half as many Black residents on average compared to low nitrate CWSs.

Agricultural contamination of groundwater as a possible risk factor for growth restriction or prematurity. WebStephen King: Twitters only advertiser will soon be MyPillow. After applying multiple imputation methods to address censored nitrate concentration data, we conducted mixed-effects multivariable regression analyses at national and regional scales. Correspondence to We found that the percent of Hispanic residents was associated with higher nitrate levels in our nationwide analysis and in all U.S. regions except the Midwest. Providing Safe Drinking Water in America: 2013 National public water systems compliance report. This regression ([NO3-N]=0.987*[NO3/NO2-N], r20.93) was used to estimate NO3-N concentrations when only NO3/NO2-N concentrations were provided. Since arsenic in groundwater often comes from geogenic rather than anthropogenic sources [5, 7], these associations may be indicative of disparities in the ability of communities to afford enhanced drinking water treatment technologies, and taken together, suggest that Hispanic communities may experience elevated exposures to multiple drinking water contaminants. High nitrate CWSs served nearly twice as many Hispanic residents on average compared to low nitrate CWSs, and CWSs that served the highest proportion of Hispanic residents (top quartile) exceeded 5mg/L nitrate nearly three times as often as CWSs serving the lowest proportion of Hispanic residents (lowest quartile; Additional file 1: Figure S2). WebBest Custom Writing Services. In our national mixed-effects regression analyses using county-level demographic data, race and ethnicity variables showed similar associations with both system average nitrate concentrations and the likelihood of system averages exceeding 5mg/L (Table3). We found that 5.6 million Americans relied on a public water supply with an average nitrate concentration5mg/L, one-half of U.S. EPAs drinking water standard, over the five-year period spanning 20102014. The University of Texas has more than 400 approved programs abroad and liberal arts students are encouraged to build on their linguistic skills and develop an understanding of social and cultural differences by spending a summer or semester immersed in another country.. In unadjusted models, the same observations were noted; very small systems were predicted to have greater likelihood of high nitrate but lower continuous nitrate concentrations than all other system sizes (Additional file 1: Table S7). Using SDWISs Geographic Area module, which some states primarily use to report the areas served parameters, we were able to augment our databases cities and counties served. 2014;468:38493. 305-R-15-001. Our correlation analysis found a positive correlation between percent Hispanic residents and percent urban households (Additional file 1: Table S2), suggesting that some of the association between Hispanic residents and nitrate levels may be related to nitrate sources in urban areas. Home ownership had a strong inverse association with nitrate in the West, where a one unit increase in percenthome ownership was associated with a 1.4% decline in nitrate concentrations (95% CI: 2.0, 0.7%); in the other three regions, home ownership was not associated with nitrate. 2015;207:8896. This procedure (bootstrap resampling, lognormal parameter estimation, imputation, and regression analysis) was repeated five times to determine the consistency of our results.

Ward MH, Kilfoy BA, Weyer PJ, Anderson KE, Folsom AR, Cerhan JR. Nitrate intake and the risk of thyroid cancer and thyroid disease. To evaluate variability across geographic regions, we conducted a similar set of regression analyses stratified into four regions (Midwest, Northeast, South, and West) defined by the U.S. Census Bureau. To evaluate disparities in drinking water exposures to nitrate levels of health concern, we conducted a separate set of analyses in which we dichotomized the outcome variable. There is no national database of water contaminant concentration data.

In the adjusted models, the Midwest had significantly lower nitrate concentrations than other regions, while only the West had a higher proportion of high nitrate systems than the Midwest. Small water supplies, particularly those that serve low-income and minority communities, may have poorer source water quality due to closer proximity to pollution sources. Washington State Departments of Agriculture Ecology and Health, Yakima County Public Works Department, U.S. Environmental Protection Agency. Perales Puchalt, principal investigator at University of Kansas, discusses his research on disparities in dementia care for Latino families and how he and his team are closing the gap as we celebrate National Hispanic American Heritage Month. A major limitation to our analysis is the potential for exposure misclassification. We did not include CWSs that purchased their water from another supplier; purchasing water systems are rarely required to test for nitrate and therefore rarely collect nitrate data. The goals of this study are to identify determinants of nitrate concentrations in U.S. community water systems (CWSs) and to evaluate disparities related to wealth or race/ethnicity. 2016;547:47081. In unadjusted models, we observed a similar estimate for the association between poverty and nitrate concentrations but did not observe an association between poverty and likelihood of high nitrate, and in contrast to the adjusted models, home ownership showed significant inverse associations with both outcomes (Additional file 1: Table S7). Similarly, the association between urbanicity and nitrate was significant in the city-level, but not the county-level analysis; a one-unit increase in the percent of households located in urbanized areas was associated with a 0.2% increase in nitrate (95% CI: 0.1, 0.3%). We found that communities with higher proportions of Hispanic residents tend to be served by community water systems with higher nitrate and greater likelihood of being over 5mg/L. 40 CFR 141.62. WebDr. CAS WebTerminology. We also could not include unincorporated areas in our city-level analysis because they are not included in Census Bureau data. More recent epidemiological studies have found associations between nitrate concentrations in drinking water and bladder cancer [19, 20], thyroid cancer [21, 22], colon cancer [23, 24], kidney cancer [25], birth defects [26, 27], low birth weight [28], and preterm birth [29, 30]. For each year in which a CWS operated (system-year), we calculated a minimum average nitrate concentration, imputing zero for nondetects, and a maximum average nitrate concentration, imputing the DL for nondetects. To be considered for any grant, you must complete the FAFSA. Nolan BT, Hitt KJ. For instance, in a low-income Hispanic community of 25,000 in the Yakima Valley in Washington State, more than 10% of private wells exceeded the nitrate MCL [51]. 2016;108(8):E416E24. We included region as a covariate in our nationwide models because of regional differences in nitrate concentrations and demographic characteristics (Table 1) and significant differences among some regions in unadjusted models (Additional file 1: Table S7). Agency for Toxic Substances and Disease Registry (ATSDR). We also anticipated that the high cost of removing nitrate from contaminated drinking water would lead to socioeconomic disparities in nitrate exposures. Use of bottled water may exacerbate disparities in pollutant exposures because lower-income residents have lower ability to pay for bottled water. Prenatal nitrate intake from drinking water and selected birth defects in offspring of participants in the National Birth Defects Prevention Study. [6], who observed no significant relationship between non-Hispanic people of color and nitrate levels in Californias Central Valley. 2011. http://factfinder.census.gov/bkmk/navigation/1.0/en/text_search:H2/d_dataset:DEC_10_SF1/d_people_basic_count:URBAN_RURAL. Springer Nature. Schaider, L.A., Swetschinski, L., Campbell, C. et al. Nevertheless, our findings are consistent with prior studies in which Hispanic communities were found to have higher drinking water exposures to arsenic, another contaminant regulated under the SDWA. In the city-level analysis, poverty was not associated with nitrate concentrations (Table4), while home ownership, which was not significant in the national county-level analysis, was associated with lower nitrate. WebRequest Trial >> Are you a librarian, professor, or teacher looking for Questia School or other student-ready resources? For instance, 9.1% of CWSs were high nitrate in counties in the top quartile for cropland, while only 1.8% of CWSs were high nitrate in counties in the bottom quartile for cropland. Thirteen states rarely or never report city served values in SDWIS (Fig. U.S. Census Bureau. This study represents the first investigation of socioeconomic disparities in drinking water contaminants at the national scale and provides new insights into the interplay of system characteristics and demographic parameters. Hennepin County Library: Brainfuse offers e-learning resources and free online tutoring. U.S. Department of Agriculture NASS. Some system administrator addresses were located hundreds of miles away from the cities served by their affiliated water systems or were located in a different state, and for 40% of the systems with both a city name (pertaining to the administrators city) and a city served designated in SDWIS, the two fields shared no overlapping cities. Future studies can extend our methods to evaluate disparities in exposures to other contaminants and links to health effects. Balazs C, Morello-Frosch R, Hubbard A, Ray I. 2001;43(4):37783. In a purely statistical sense, larger water systems may be more likely to detect elevated nitrate levels because they are required to test more frequently and, in the case of groundwater systems, might draw from a greater number of source water wells. Data that we compiledfor U.S. CWSs, including service areas and purchaser-seller connections, are provided in Additional files 2 and 3. Drinking-water exposure to a mixture of nitrate and low-dose atrazine metabolites and small-for-gestational age (SGA) babies: a historic cohort study. The inverse association observed nationally may be heavily influenced by the South, which has the lowest proportion of high nitrate systems, the most water systems, and the highest proportion of Black residents of all regions. For each system, we then calculated a five-year system average concentration as an interval, with the lower/upper bounds of the interval represented as the average of all of the minima/maxima of system-year intervals, respectively. This observation is consistent with our data: of the 41,781 CWSs we paired with county demographics, very small systems were significantly more likely than larger systems to lack nitrate sample results over the five-year study period (5.2% of very small systems missing nitrate data compared to 1.8% of larger systems; Pearson 2=301). J Am Water Works Assoc. Environ Health. Our target population were CWSs in each U.S. state that were active at some point between 2010 and 2014. We observed significant differences in the demographics and land use patterns between high nitrate and low nitrate (mean<5mg/L) CWSs (Table2). In our analysis, we are not able to identify the relative importance of proximity to nitrate sources and management-related factors. This study was funded by the Casey & Family Foundation. There are 574 federally recognized tribes living within the Heres Elon Musks response. Health-based violations of the SDWA were more common in poorer communities with higher proportions of Hispanic or African-American residents; the effects of race and ethnicity were not apparent in more affluent communities [8]. Pennino MJ, Compton JE, Leibowitz SG. Washington DC: National Center for Environmental Assessment, Office of Research and Development, U.S. Environmental Protection Agency; 2017. Although administrative address information was available for nearly all water systems, we concluded that such data did not reliably identify the areas served by each CWS. State was included as a random effect to capture the influence of different monitoring and reporting practices for drinking water and differences in state regulations of pollutant sources and enforcement.

Volume 94: ingested nitrate and nitrite, and cyanobacterial peptide ToxinsLyon. In some cases units (mg/L, g/L) were either missing or appeared to be misreported (e.g., 0.2ng/L), complicating the interpretation of sample results, particularly those that substantially diverged from other samples collected from the same system. Few states provide public access to electronic records documenting the service areas of their public water systems, so we relied on the information included in SDWIS. 2013;121(9):10839. Separate variables, city served and county served, describe the areas to which a system directly provides water, and the primacy agency code specifies the agency that has regulatory oversight of the water system (typically a state agency encompassing the cities or counties served). In the unadjusted models, the Midwest and West had the highest proportions of high nitrate systems, while the West had higher nitrate concentrations than the Midwest and South. 2008;26(1):186205. 6.2 Assess glycemic status at least quarterly and as needed in patients whose therapy has recently changed Epidemiology. Bullard RD, Johnson GS. Am J Public Health. We did not impute values for system averages based entirely on detected concentrations (37.9% of systems) because we could calculate these averages directly. Nitrate (NO3-N) concentrations were used when available to estimate each CWSs annual nitrate concentration. 6.1 Assess glycemic status (A1C or other glycemic measurement such as time in range or glucose management indicator) at least two times a year in patients who are meeting treatment goals (and who have stable glycemic control).E.

Investigating social inequalities in exposure to drinking water contaminants in rural areas. Similar effect estimates were observed in unadjusted models (Additional file 1: Table S7). The U.S. EPAs Integrated Risk Information System (IRIS) is undertaking a broad re-evaluation of the health effects of nitrate and nitrite [34]. Rubin DB. In some cases, this was related to data handling problems; for instance, some records were only available in paper reports, and in other cases, this may reflect a lack of compliance with monitoring requirements, which is more likely for small rural communities who may not be able to afford testing or where there is less enforcement of testing requirements.
