What stands out among these

The busiest contractor on these records is Associated Environmental, INC, named on 78 of them (22.3%), ahead of Larsen and Associates, INC (61) and Cascade Drilling (44). The oldest record here was completed in 1973 and the most recent in 2026, and the deepest well on file reaches 175 feet — a monitoring well/observation/piezometer well drilled by Strader Drilling Co., INC in 1996.

Plugging records — for monitoring well/observation/piezometer in Jefferson County

61 of the 350 records for monitoring well/observation/piezometer in Jefferson County carry a plugging report (17.4%), filed on form WWC-5P. The other 289 do not.

That is not a list of abandoned wells, and this site never calls them that. Kansas defines abandonment by use — a well unused for two years — and nothing in this register tracks use. What the absence of a plugging report does mean is that the State has never been told the well was sealed. On the 58 records here completed before 1995, that is exactly what a buyer checks. Why it matters and who pays.

Who drilled them

An unplugged well on land in Jefferson County?

289 of the 350 records in Jefferson County have no plugging report on file. If a well on your land is no longer used, Kansas requires it to be plugged and the duty falls on the landowner — with cost-share of up to USD 1,000 per well through the Kansas Department of Agriculture. This site reads the register; it does not drill and it does not plug. Tell us where and we pass the request to licensed Kansas well contractors.

We recommend no contractor and we are nobody's agent. We have no arrangement with any firm today — we are collecting these requests in order to go and find them. What we do with this.
