or the 20th consecutive year (2020 was cancelled due to the COVID pandemic) the California Section of AIPG presented awards at the California Science and Engineering Fair (CSEF) via a virtual or online pro- gram format on April 13. Mark Rogers and Dave Sadoff, AIPG California Section Southern and Northern Vice Presidents, respectively, judged a
total four (one Junior and three Senior Division) geoscience projects.
The First-Place winner was Ayush Agrawal with his proj- ect entitled “Early Detection of Arsenic Contamination Risk Using Satellite Imagery and Machine Learning”. The purpose of his project was to determine if a significant correlation could be established between hyperspectral imagery satellite wavelengths and arsenic contamination in soil (and to a lesser degree groundwater) at varying landcover locations in the U.S. Ayush’s motive in pursuing this project was improving public health and safety after some of his family members in India ingested arsenic-contaminated water. After making interfer- ence corrections based on errors resulting from satellite-based imagery vs. lab- based imagery, Ayush determined that machine learning (ML) regression model SD-BPNN was the best suited in detecting arsenic in soil (reflectance <0.8 mg/ kg) of the four models studied and 16 correlations completed. Data improvements would include considering more variables (land / crop cover, soil type, proximity to bedrock / water source, elevation) going into the ML modeling that affects arsenic concentrations in soil to check repeatability. Ayush received an AIPG awards certificate and $250 for his efforts.
The AIPG California Section also presented Second and Third-Place Award Certificates (which included $150 and $100, respectively) to the following students (see abstracts at
http://cssf.usc.edu/Current/Panels/):
• Anneli and Mathilde Macdonald for their project “Water Quality Conundrum: The Effect of Rainfall on Septic Levels in Rural Creeks”; and
• Vivian Dang and Elizabeth Conrad for their project “Tsunami Coastal Defenses – What is the Best Coastal Defense Against Tsunamis”.
Once again, it was a pleasure to discuss projects with such bright students who represent our future. We are hopeful we will be conducting in-person interviews at the CSEF in 2022. Congratulations to the winners!
