The Environmental Protection Agency has said it will soon release the final tally of the nation’s most polluted counties, which it plans to release to the public by the end of March.
The report is expected to show how many communities are worse off than the rest of the country.
The EPA said in January that counties in New Jersey and New York had the most pollution, followed by West Virginia, Mississippi, Louisiana, Alabama, Alabama and Mississippi.
New York, which ranked No. 1 in the country for ozone and particulate matter pollution in 2015, was the worst in the nation for pollution.
But many of the worst polluters in New York have been in the state’s poorer areas, such as the Bronx and Queens.
Among those that have fared the worst is the Bronx, home to some of the most impoverished and struggling neighborhoods in the city, where residents struggle to get by on meager income and can’t afford to send their children to school.
The study comes as the EPA and its states, which represent much of the states worst-hit by pollution, continue to face pressure to improve pollution data, according to The Associated Press.
“We’re going to see more data from the states,” said John Hudak, who was EPA administrator in the Trump administration and was involved in the review.
“The EPA will be looking at the impact of the air pollution and what the states are doing to address it, and how much it’s costing them.”
The AP also reported on Thursday that Trump’s administration is looking to move the deadline for releasing the data back to April.
The AP first reported on the Trump EPA’s plans to push back the deadline to April 3, 2018.
Environmental groups have criticized the move.
The deadline would have allowed the public to see pollution data for the first time since the 1980s.
EPA officials have said that in the years before then, they had not released the data.
“While we have been very careful about not releasing the information at this time, the data will be released at the appropriate time,” an EPA spokesperson told the AP.
The Trump administration has been pushing for the data to be released sooner, including by March.
Officials in the EPA’s Office of Air and Radiation released a study on Friday that found the EPA did not track data about ozone pollution, particulate pollution and other pollutants that are particularly harmful to the health of people.
“EPA is aware of the need for improved transparency in the analysis of the Nation’s pollution data,” the study stated.
“Ozone is one of the major pollutants that cause air pollution, and its analysis should include data on air pollution from sources such as motor vehicles, industrial plants, agriculture, residential dwellings, and other sources.
The air and water quality data should include information on the health impacts of these pollutants, as well as data on how much of those pollutants are coming from vehicles.”
A White House spokesman said Thursday that the administration had made the request for the information from states.
“If the EPA does not receive the requested data within 30 days, the request will be reviewed,” the spokesperson said.
The president, who has been a vocal critic of the EPA, has previously called for the agency to release the data as soon as possible.
