RECEIVED DIY & LAB PARTICIPANTS KITS
Project Harvest participants were randomly assigned to one of two sampling groups. Participants in the lab group collected rainwater, soil and/or plant samples throughout the year to be analyzed at University of Arizona laboratories. The DIY group was provided materials on how to collect rainwater and soil samples, perform contaminant analyses for arsenic and microbial contamination and interpret results at home. The DIY participants submit their results, rather than samples, to university researchers.

What did we learn?
In 2019-2020 only the first and last winter samples are reported. We had to cancel the first and last monsoon sample seasons due to COVID-19

Please note that metals occur naturally in the environment. While we can measure the level of a metal in certain substances, it is difficult to know the original source of the metal. For example, arsenic may be found in soil in many parts of the state because it naturally occurs in these regions.
