This indicator reports the respiratory Hazard Index (HI) from the analyzed carcinogens in ambient outdoor air. The HI is the sum of hazard indices for those air toxics with reference concentrations based on respiratory endpoints, where each hazard index is the ratio of exposure concentration in the air to the health-based reference concentration set by…
This indicator reports the estimated concentration of diesel PM in air. The value of the indicator is in µg /m3. Areas with higher diesel PM levels (i.e., more harmful to human health) are placed higher in percentile (national ranking). The percentile could be interpreted as, for example, for a place at the 80th percentile nationwide,…
This indicator reports the percentage of days with particulate matter 2.5 levels above the National Ambient Air Quality Standard (35 micrograms per cubic meter) per year, calculated using data collected by monitoring stations and modeled to include counties where no monitoring stations occur. This indicator is relevant because poor air quality contributes to respiratory issues…
This indicator reports the percentage of days per year with Ozone (O3) levels above the National Ambient Air Quality Standard of 75 parts per billion (ppb). Figures are calculated using data collected by monitoring stations and modeled to include census tracts where no monitoring stations exist. This indicator is relevant because poor air quality contributes…
This indicator reports the percentage of children reported safe in their neighborhood. Data are acquired from the 2023 topical data of the National Survey of Children’s Health (NSCH). Source U.S. Census Bureau, National Survey of Children’s Health, 2023. Source Description The National Survey of Children’s Health (NSCH), funded and directed by the Health Resources and…
This indicator reports the percentage of children living in neighborhood without vandalism, such as broken windows or graffiti. Data are acquired from the 2023 topical data of the National Survey of Children’s Health (NSCH). Source U.S. Census Bureau, National Survey of Children’s Health, 2023. Source Description The National Survey of Children’s Health (NSCH), funded and…
This indicator reports the estimated lifetime inhalation cancer risk from the analyzed carcinogens in ambient outdoor air. The value of the indicator is persons per million lifetime. Areas with higher air toxics cancer risk levels (i.e., more harmful to human health) are placed higher in percentile (national ranking). The percentile could be interpreted as, for…
This indicator reports the estimated millions of gallons of water used per day. Water use refers to water that is withdrawn by public and private water suppliers and includes water provided for domestic, commercial, industrial, thermoelectric power, and public water uses, as well as water that is consumed or lost within the public supply system….
This indicator displays the total number of drinking water violations recorded in a two year period. Health-based violations include incidents where either the amount of contaminant exceeded the maximum contaminant level (MCL) safety standard, or where water was not treated properly. In cases where a water system serves multiple counties and has a violation, each…
This indicator reports the estimated millions of gallons of water withdrawn per day for irrigation. Crop irrigation withdrawals and irrigation consumptive use refer to water removed and consumed, respectively, from a groundwater or surface-water source to produce agricultural crops.Estimation of irrigation withdrawals using irrigation consumptive use and efficiencies neglects some components of water use for…
