What stands out among these

The busiest contractor on these records is Larsen and Associates, INC, named on 54 of them (19.6%), ahead of Geocore, INC (31) and Hydro-logic, INC (17). The oldest record here was completed in 1985 and the most recent in 2025, and the deepest well on file reaches 190 feet — a monitoring well/observation/piezometer well drilled by Kgs in 1986.

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

65 of the 275 records for monitoring well/observation/piezometer in Marshall County carry a plugging report (23.6%), filed on form WWC-5P. The other 210 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 32 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 Marshall County?

210 of the 275 records in Marshall 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.
