Jana Elementary School located in Hazelwood, MO made national news as having “unacceptable high” levels of radioactive waste found near the school. The safety concerns for the Hazelwood School District children required immediate action to assess the risks. Under the FUSRAP umbrella, the AVESI field teams prepared their strategies to provide the necessary answers to the community and performed this accelerated work under the scrutiny of the national media and local organized groups.
AVESI personnel performed expanded soil sampling and structure surveys inside/outside of Jana Elementary School in record time. Field work performed by AVESI personnel included total radiological activity and removable surveys on the interior and exterior of Jana School. This task encompassed parcel soil characterization surveys and sampling; soil remediation verification surveys; air, SW, and sediment environmental compliance monitoring; and safety and health inspections.
Once the investigation and characterization data collection phase were completed, AVESI personnel prepared MARSSIM-based FSS Evaluation (FSSEs), PDI WPs, PDIRs, PRARS, EMPs, and safety audit and QC reports.
This was an extremely high-profile project that was required to be completed on an accelerated schedule under intense public scrutiny:
- The Jana School property borders Cold Water Creek, a known corridor for FURSAP related radiological contamination. This response required extreme urgency to determine if the children in this area were at risk.
- In just under four weeks, AVESI field teams were dedicated to the investigation and characterization activities providing smear, pavement sediment, and soil samples resulting in laboratory-generated data for the Jana School investigation resulting in over 1700 datapoints as detailed under Accomplishments.
- AVESI field crews collected 922 structural measurements and 790 soil samples. Our lab personnel analyzed the samples collected at the on-site lab and our data management group conducted 100% validation/verification of the data packages.
- Interior and exterior radiological surveys were performed equal to 4.7 acres of the total area.
- Performed radiological surveys on 927 structure surfaces.
- Performed GWS, including 305,101 measurements, over an area of 74,709 m2 (18.5 acres).
