What this page is, and what it is not
A count of the completion records that name this contractor. It is not a rating, a review, or a comment on anyone’s work — nothing in the WWC-5 register measures quality. What it does show is where a contractor works and what depths they report, which is what somebody comparing quotes actually wants to know.

Plugging records — on this contractor's records
2,898 of the 6,122 records on this contractor's records carry a plugging report (47.3%), filed on form WWC-5P. The other 3,224 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 0 records here completed before 1995, that is exactly what a buyer checks. Why it matters and who pays.
An unplugged well on land in Kansas?
3,224 of the 6,122 records in Kansas 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.
