Is it getting better or worse? A trend for every well.

The question regulators always ask. Statvis runs GWSDAT-style trend analysis on every well, for every analyte, from monitoring data that may span a dozen events and several consultants.

Test every well for a trend. See the plume shrinking, or not.

Run Mann-Kendall trend tests and fitted trends across every monitoring well at once, then isolate any well to see its direction, significance and half-life.

Ready for monitoring reports

Every well, every constituent. One table.

A traffic-light table shows every well against every constituent over time, with trend classes and thresholds, so you can see where the plume is shrinking and where it is not.

Trend classes per well and constituent
Statistical and absolute thresholds
Scrub through monitoring dates

Per-well analysis includes

Smoothed concentrationa local trend line through every event
Linear trendwith confidence interval and half-life
Mann-Kendallp-value for a monotonic trend
Non-detectsmarked, not dropped

Watch the plume over time. Area, mass and average, by date.

Plume animation shows the concentration surface changing across monitoring events, with the plume boundary at your chosen threshold.
