Wellfield

Wellfield map

Color wells by available perf, liquid elevation, health, methane, or vacuum. The liquid isopach is an inverse-distance surface of liquid elevation (top of casing − depth to fluid). The red wash is collection deficit — low unsaturated screen, weak vacuum, nearby SEM.

Liquid isopach

Filled contours of liquid elevation from well soundings. A mound is perched leachate — screen goes underwater and collection drops. Cell 3 is the demo under-drained mass.

Available perf

Unsaturated perforated interval. Below 5 ft the well is a passenger, not a collector. Mean now 11.2 ft.

SEM vs collection

12 exceedance pins. Cluster against the Cell 3 liquid mound and the EW-31 thermal anomaly.
