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: http://www.aqmd.gov/home/regulations/compliance/air-monitoring-activities
UPDATE - SCAQMD announces a Summary of Efforts report:The SCAQMD has undertaken unprecedented, extensive efforts to identify and reduce sources of hexavalent chromium in the City of Paramount. This Summary of Efforts in Paramount(PDF included below), summarizes the significant progress made and provides highlights of monitoring, enforcement, rule development, public outreach, and coordination efforts.
Additionally, the Paramount Environmental Portal is provided by the City of Paramount, offering facts and information to residents and businesses about our City’s environment. The site focuses on the areas of air, water, and soil: https://paramountenvironment.org/
Please contact the office of the Assistant Superintendent of Business Services (562) 602-6025 if you have questions or comments.
The school district regularly publishes and sends home environmental information pertinent to our school community.

NEW - District Indoor Air Quality Testing - March 29, 2019 Survey Report
Report Excerpts - Hexavalent Chromium (Cr(VI)):
No airborne Cr(VI) was detected above the OEHHA NSRL inside any of the classrooms during the 24 hours of sampling.
District Cr(VI) ambient air monitoring - School Results and information - The synopsis of the district schools report is as follows:
All indoor Cr(VI) air levels measured at both school sites ranging from were well below the South Coast Air Quality Management District (SCAQMD) long-term health risk level of 0.0002 micrograms per cubic meter (μg/m3)
Indoor Cr(VI) air levels measured at Gaines ranged from Not DetectedJ to 0.0000336 micrograms per cubic meter (μg/m3) were well below the City of Paramount stationary monitor result for the period of September 26 to 29, 2018, which ranged from 0.00015 to 0.00016 μg/m3 for the 2, 24- hour samples collected and analyzed.
The outdoor Cr(VI) air levels measured at Gaines was 0.000103 μg/m3 and was below the City of Paramount stationary monitor result for the period of September 26 to 29, 2018, which ranged from 0.00015 to 0.00016 μg/m3 for the 2, 24-hour samples collected and analyzed.
Indoor Cr(VI) air levels measured at Lincoln ranged from Not Detected to 0.0000559 μg/m3 were below the SCAQMD stationary monitor result for the period of September 23 to 29, 2018, which ranged from 0.00006 to 0.00022 μg/m3 for the 2, 24-hour samples collected and analyzed.
The outdoor Cr(VI) air levels measured at Lincoln was 0.0000457 μg/m3 and was below the SCAQMD stationary monitor result for the period of September 23 to 29, 2018, which ranged from 0.00006 to 0.00022 μg/m3 for the 2, 24-hour samples collected and analyzed.
No airborne Cr(VI) was detected above the OEHHA NSRL inside any of the classrooms during the 24 hours of sampling. One exterior sample collected on the Roof of Gaines Room 1, exceeded the OEHHA NSRL. 0.00148 micrograms (μg) Cr(VI) as compared to the OEHHA NSRL of 0.001 μg was detected in the ambient outdoor air from air pollution from local manufacturing during the same sampling period that Classroom 1 was monitored. This is suggestive of an exterior ambient air issue in the vicinity of Gaines. The outdoor levels measured at Lincoln were 0.000638 μg, below the OEHHA NSRL.
All Cr(VI) air levels are well below occupational exposure levels established by California Division of Occupational Safety and Health (DOSH -- better known as Cal/OSHA) and other consensus levels such as American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value and National Institute of Occupational Safety and Health (NIOSH) Recommended Exposure Level.
All Cr(VI) air levels (level measured and Limit of DetectionM) were a magnitude of 4 to 15 times the California Department of Toxic Substances Control (DTSC) Office of Human and Ecological Risk (HERO) Screening LevelsN, (hereafter, DTSC-SLs). It is noted that all of the outdoor samples collected at school sites from December 21, 2016 through March 26, 2019, measured by both the City of Paramount and the SCAQMD were in excess of the DTSC-SLP. These levels in excess of the DTSC-SL are suggestive of a need for on-going further investigation and a quantitative baseline risk assessment. It is also noted that the Limit of Detection (LOD) for the method used is greater than the DTSC-SL which introduces limitations to the assessment and suggests the need to determine if a method with a LOD below the DTSC-SL can be developed.
The entire indoor air quality (industrial hygiene survey) report is attached and can be located in the Attached Documents Area below. This survey was a joint collaboration between the Los Angeles County Department of Public Health (LACDPH) and the Paramount Unified School District. The District paid for the field collection of data and report; LACDPH observed the process and paid for the laboratory analysis. This survey was also partially funded as a benefit of membership in the Alliance of Schools for Cooperative Insurance Programs (ASCIP). This report contains a presentation of data, summary of findings, methods, and recommendations related to findings.

The presentation includes information about process, results and testing methods:
District Cr(VI) ambient air monitoring - School Results and information. September 2017 - 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/m3. Additionally, 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)
Information on Hair Sampling of Children in Paramount
The District received information that there have been reports of hair sampling in children in Paramount, and claims that the testing has resulted in concerning results.

From: Charlene Contreras [mailto:firstname.lastname@example.org] Sent: Wednesday, February 21, 2018 2:26 PM To: John Carver Cc: John Moreno Subject: RE: indoor air sampling results
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.
