Groundwater Trend Map — Mann-Kendall per Well, Drawn on the Site
The question a regulator asks about a monitored site is whether it is getting better. Answering it well by well and then reading the answers off a table loses the one thing that matters: whether the improving wells are in the same place as each other. Each well gets a Mann-Kendall test — non-detects handled as censored data rather than dropped — and the result is drawn where the well is.

One row per well, with coordinates and whatever you want mapped. It is read in this tab and never uploaded.
A made-up site: Kestrel Lane Terminal does not exist. Fourteen wells sampled quarterly for benzene, six rounds from 2024-12-11 to 2026-03-14, on a local grid in metres. Each arrow is a Mann-Kendall test of that one well's record — the source area is falling and the leading edge of the plume is still rising. Two wells end in non-detects and one was installed too recently to test.
Or paste the rows
Copy a block straight out of a spreadsheet — tabs, commas and semicolons all work, and you do not have to tell us which. A workbook you dropped appears here as text; editing it re-reads it as text.
