Monitoreo del plomo en el vecindario de Pilsen /

Based on this new data, the Illinois EPA has requested that the Illinois Attorney General initiate legal action against H. Kramer relative to its contribution to a violation of the lead National Ambient Air Quality Standard.

The first results from the new ambient monitor indicate that H. Kramer is contributing to the elevated ambient air lead levels.

The Illinois EPA is investigating to determine why the elevated lead events occurred. This investigation includes: adding a second monitor in the area, at Benito Juarez Community Academy; increasing the frequency of sample collection from every six days to every three days at the Perez and Juarez monitors; and conducting investigations of numerous sources in the area, including H. Kramer, a local brass and bronze smelter.

The National Ambient Air Quality Standard is based on an average of three months of readings. Although most of the readings in 2010 were well below the standard, four elevated samples between November 2010 and January 2011 caused the three-month average to be greater than the National Ambient Air Quality Standard.

Air samples at the Perez monitor were collected once every six days and typically showed lead levels well under the new, more protective National Ambient Air Quality Standard. However, periodically there were elevated lead readings at the monitor (elevated in 11 of the approximately 60 samples taken in 2010).

In January 2010, the Illinois Environmental Protection Agency (Illinois EPA) placed a monitor on the roof of Manuel Perez Jr. Elementary School to sample ambient air concentrations of lead in the area. The monitor was located there because of the Illinois EPA's knowledge of lead emissions from local sources, concern about the proximity of emissions sources to residents and schools, and expressed community concern.
