Did you know 87% of children under 18 in Arizona live in counties with unhealthy levels of ozone pollution? Or that 53% of public water utilities in the state experienced drinking water violations (compared to the National average of 32%) in 2019? There are 1.7 million children in Arizona, and approximately 20% of them live in poverty. Poverty is an important social determinant of health; poverty hurts children and their families. Children of color and young children are disproportionately poor and experience many issues that lead to adverse health outcomes. All children deserve a safe and healthy environment to grow and develop.
This profile highlights key Arizona children’s environmental health indicators, federal support received by the state for environmental health, health equity and climate and health programs, and a spotlight feature on a children’s environmental health-related topical issue.

Arizona Spotlight: Navajo Community Groups Dine C.A.R.E and To Nizhoni Ani
The Navajo Nation has faced years of environmental contamination from historical uranium mining and the placement of coal-powered incinerators on their lands. Their 
residents have suffered from breathing coal ash and polluted air. Uranium mining was banned in 2005 but has left a legacy of extraction contaminated water sources, including private wells.
Two Navajo community groups —Dine C.A.R.E. (Navajo Citizens Against Ruining our Environment) and To Nizhoni Ani (Sacred Water Speaks)–have been working to address these injustices for years. An overarching goal of their efforts is to make sure that the 
Navajo Nation transitions from an over-reliance on coal as an economic engine to more affordable and sustainable sources of energy, They are prioritizing and promoting sources that do not pollute Navajo air, land and water – and that are in line with their Dine way of life and fundamental principles. These organizations are recognized as leaders on these issues They collaborate with national environmental organizations, travel to Washington DC to advocate on behalf of the Navajo Nation and are committed to finding clean energy solutions and associated jobs on Navajo lands.

Children’s Environmental Health Indicators Selection Criteria
Children’s environmental health indicators (CEHIs) are measures that can be used to assess environmental hazards, exposures, and their resulting health outcomes in children. The below criteria are used when determining which indicators to utilize:
-
- Relevance: Each headline indicator should be a clear, understandable indicator of children’s environmental health, with broad relevance for a range of audiences at the state level – with relevance to the national level.
- Representativeness: The indicators as a package should provide a representative picture of children’s health and relation to the environment.
- Traceability: Each indicator should be calculated using an agreed-upon (and published) method and accessible and verifiable data.
- Timeliness: Each indicator should be calculated regularly (at least biennially), with a short lag between the end of the period and publication of the data.
- Data adequacy: The available data needed for the indicator must be sufficiently robust, reliable and valid.
- Universality: Indicators must be comparable across all or very nearly all 50 U.S. states. [/expand]
Indicator Notes and References
Safe Drinking Water
Air Quality
- Indicator Note: In this fact sheet, counties with “unhealthy” ozone pollution are those receiving a grade of D or F for ozone pollution in the American Lung Association’s 2020 State of the Air report. Approximately 80,569 or 5% of children live in Arizona counties where ozone pollution was not monitored
- Reference: Ozone Pollution. American Lung Association. 2020 State of the Air. Report card: Arizona. Data from U.S. Environmental Protection Agency’s Air Quality System. Accessed on April 21, 2020.
Warming Temperature
- Indicator Note: Warming matters — it drives most of the hazards associated with climate change such as extreme weather, heat days, droughts and heavy downpours. Children are more vulnerable to harm from extreme heat and to the other cascading effects of warming temperatures.
- Reference: AMERICAN WARMING: The Fastest-Warming Cities and States in the U.S. April 17, 2019. Climate Central. Data from National Centers for Environmental Information, National Oceanic and Atmospheric Association. Accessed on October 28, 2019
Toxic Chemicals
- Indicator Note: EPA’s Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. Certain industrial facilities in the U.S. must report annually how much of each chemical is disposed of or released on and off site. Many of these chemicals are known carcinogens, developmental toxicants, and neurotoxicants, such as arsenic, lead and mercury, that adversely impact children’s health.

Neurodevelopmental Disorders
- Indicator Note: Mounting scientific research links environmental exposures with risk of Attention-Deficit Hyperactivity Disorder (ADHD). Attention-Deficit Disorder (ADD) and Autism Spectrum Disorder (ASD). Neither genetics nor changing diagnosis or other artifacts fully account for the increased incidences of these conditions. ADHD, ADD and ASD data are for Arizona children aged 3-17 ages.

Maternal and Child Health Bureau, Health Resources and Services Administration. Accessed on March 25,2020.
Asthma
- Indicator Note: A wealth of research links exposure to poor outdoor air quality, including high concentrations of ground-level ozone, with the exacerbation of children’s respiratory illnesses, including asthma. Several studies link it with the onset of childhood asthma.
- Reference: Asthma prevalence. 2017-2018 National Survey of Children’s Health. Title V Maternal and Child Health Services Block Grant National Performance and Outcome Measures. Prevalence of current asthma, age 0-17 years. Data Resource Center for Child and Adolescent Health. Maternal and Child Health Bureau, Health Resources and Services Administration. Accessed on March 25,2020.
Pediatric Cancer
- Indicator Note: Although cancer in children is rare, the rate of pediatric cancer has been increasing since the 1970s. It is the leading disease related cause of death past infancy in U.S. children, Neither genetics nor improved diagnostic techniques can explain the increased rate. According to the President’s Cancer Panel’s 2008-2009 Annual Report, “the true burden of environmentally induced cancer has been grossly underestimated”
- Reference: Arizona Childhood Cancers Incidence Request for children age 0-19. Age-adjusted rate for 2005-2015. Centers for Disease Control and Prevention. Wide-ranging Online Data for Epidemiologic Research (WONDER). Accessed on March 25, 2020.
Blood Lead Levels
- Indicator Note: In 2017, 11.4% of Arizona children under age 6 were tested for blood lead levels (BLLs). Of those tested, 0.3% had a BLL>= 5 µg/dL. Often the most vulnerable children are not tested, and not all who are tested get reported, so 0.3% is likely an underestimate of the true scope of children’s elevated blood lead in Arizona. There is no safe level of lead exposure for children. A potent neurotoxicant, lead reduces IQ and impairs other cognitive, behavioral and developmental functions.

All children deserve and need a safe and healthy environment to grow and develop. They need clean air to breathe, safe water to drink, nutritious food to eat, and healthy places in which to live, learn, and play. Early exposure to harmful agents can lead to acute and chronic adverse outcomes. Infants and children are especially vulnerable to environmental exposures because they breathe, eat and drink more, in proportion to their body size, than do adults, and because their bodies and brains are still developing.
A blueprint for Protecting Children’s Environmental Health Network set out to identify a set of CEHIs that can be used to provide an understanding of children’s environmental health at the state level. Through this process, CEHN found that robust, valid, and regularly updated state level data–that are comparable across most states–were not readily accessible. States need adequate funding and capacity to collect and make accessible reliable CEHI data in order to set goals and track progress towards improving children’s health.
Children are our future – society has a moral obligation to protect them. Exposure to environmental hazards can and must be prevented. Prevention requires strong environmental regulations, fully funded and supportive public and environmental health programs and a robust workforce.
