District Air Quality Resources

The Paramount Unified School District continues to work on an ongoing basis with the South Coast Air Quality Management District (SCAQMD), the County Public Health Department and other environmental regulatory and enforcement agencies to provide our district information regarding the concerns and findings relating to Hexavalent Chromium levels in the community. The SCAQMD is the regulatory agency in charge of the air quality in the area, as well as the agency providing information regarding the current investigation. The SCAQMD implemented the placement of testing equipment in school district property, rotating the testing equipment to various school sites and regularly reviewing and releasing results of those tests in their web site, which also includes information about their air monitoring activities in the City of Paramount, their meetings and processes:

District Cr(VI) ambient air monitoring - School Results and information.  The synopsis of the district schools report is as follows:

No airborne Hexavalent Chromium (Cr(VI)) was detected inside any of the classrooms during the five days of sampling. Small quantities of Cr(VI) were detected in the ambient outdoors air from air pollution from local manufacturing during the same sampling period that classrooms were monitored.

 Cr(VI) results inside the classrooms were below the limit of detection and below the OEHHA NSRL for inhalation of 0.001 μg/m3. Outdoor levels measured ranged from less than 0.39 to 0.40 μg/m3Additionally, these levels are well below occupational exposure levels established by California Division of Occupational Safety and Health (DOSH -- better known as Cal/OSHA) as referenced in the report underTable I.   (Sept/2017)

HI John,


I apologize for the delay on the indoor air sampling results. I am trying to sort through some logistical issues but I don’t anticipate too much longer.


As for hair sampling of children in Paramount, I contacted Jane Williams, and she is not aware of any such study. We at DPH haven’t heard of a hair study either.


Best regards,
