Monitoring/sampling wells in Weld County

10,978 of the 43,473 well permits in Weld County — 25.3% — are decreed for monitoring/sampling.

How this group compares

Weld County holds 12.1% of Colorado’s 91,022 monitoring/sampling permits, while holding 7.2% of the register overall — so it is over-represented in this use.

Monitoring/sampling means not a water supply at all — a hole drilled to watch the groundwater. These sit on the same register and are not wells anyone drinks from.

What happened to these permits

6,150 of the 10,978 permits decreed for monitoring/sampling in Weld County ended with a well the Division was told about — 56.0%. And 2,282 expired without one: 20.8%.

An expired permit is the trap in a rural sale. A seller can produce a permit that lapsed years ago, and a permit is not a water right — the two are separate, and a purchase turns on both. What an expired permit does and does not mean.
