SARS-CoV-2 concentrations measured in NYC Wastewater
Results of sampling to determine the SARS-CoV-2 N gene levels in NYC DEP Wastewater Resource Recovery Facility (WRRF) influent, disaggregated by the WRRF where the sample was collected, date sample was collected, and date sample was tested. RT-qPCR was changed to digital PCR in April of 2023, resulting values are about 10-20 times higher than those of RT-qPCR. Please refer to this supporting documentation for more technical information Data may be used to track trends in SARS-CoV-2 concentrations in NYC WRRF influent. Dataset does not include COVID-19 case rates.

Columns
Each source column, with the name and type we use to store it.
The publisher has not provided a data dictionary.
0 of 9 columns carry a concept; 9 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
