The wastewater in the overground drainage was lead into the underground drainage inside the market and then flow into the wells on the edge of the market. And we did a spot-check sampling across all the overground drainages. To detect for the presence of SARS-CoV-2 RNA, RT-qPCR was performed. The locations of the positive samples were marked in the map of the market within yellow.
