Output Data from the Water-Quality Trends Analysis for Selected Streams Throughout Puerto Rico, Water Years 1958 - 2022
The output data package for this data release includes tables with summary results from trend analysis of water quality data from streams in Puerto Rico. The files in this output data package include a summary of the results of 1) Mann-Kendall tests for the entire period of record for each parameter for each site, 2) Seasonal Mann-Kendall Trend tests on both unadjusted and streamflow adjusted concentrations for the entire period of record for each parameter for each site, and 3) Mann-Kendall Trend tests for the following two time periods for each parameter for each site: 2008-2022 (POR1), and 2013-2022 (POR2).
