# Environmental Remediation, Injection water wells in Kansas — 1,827 records > 1,827 Kansas wells are recorded for environmental remediation, injection. Where they are, how deep they go and who drilled them. ## Environmental Remediation, Injection **1,827** of the 314,779 WWC-5 records in Kansas — 0.6%. ### What this use means a use the record files under this heading. *Medians, on the records where the driller reported a figure — never a mean, which a handful of deep irrigation wells would carry away* | Measurement | Median | 90th percentile | Kansas median | |---|---|---|---| | Depth | **36.2 ft** | 67.8 ft | 60 ft — shallower here (1,790 records, 98 %) | | Static water level | **20.9 ft** | 43.2 ft | 24 ft — lower here (903 records, 49 %) | | Estimated yield | **50 gpm** | 100 gpm | 25 gpm — higher here (11 records, 1 %) | ### Where they are | County | Records | Share | |---|---|---| | [Sedgwick](/county/sedgwick/environmental-remediation-injection.md) | 547 | 29.9% | | [Mcpherson](/county/mcpherson.md) | 200 | 10.9% | | [Wyandotte](/county/wyandotte.md) | 192 | 10.5% | | [Saline](/county/saline.md) | 96 | 5.3% | | [Ellis](/county/ellis.md) | 78 | 4.3% | | [Reno](/county/reno.md) | 62 | 3.4% | | [Cloud](/county/cloud.md) | 54 | 3.0% | | [Pratt](/county/pratt.md) | 51 | 2.8% | | [Harvey](/county/harvey.md) | 49 | 2.7% | | [Rush](/county/rush.md) | 48 | 2.6% | | [Phillips](/county/phillips.md) | 44 | 2.4% | | [Rice](/county/rice.md) | 42 | 2.3% | | [Riley](/county/riley.md) | 39 | 2.1% | | [Edwards](/county/edwards.md) | 38 | 2.1% | | [Kiowa](/county/kiowa.md) | 32 | 1.8% | | [Johnson](/county/johnson.md) | 30 | 1.6% | | [Scott](/county/scott.md) | 25 | 1.4% | | [Ness](/county/ness.md) | 20 | 1.1% | | [Pottawatomie](/county/pottawatomie.md) | 19 | 1.0% | | [Ellsworth](/county/ellsworth.md) | 18 | 1.0% | | [Cowley](/county/cowley.md) | 13 | 0.7% | | [Butler](/county/butler.md) | 13 | 0.7% | | [Coffey](/county/coffey.md) | 12 | 0.7% | | [Douglas](/county/douglas.md) | 10 | 0.5% | | [Montgomery](/county/montgomery.md) | 10 | 0.5% | | [Dickinson](/county/dickinson.md) | 9 | 0.5% | | [Cheyenne](/county/cheyenne.md) | 9 | 0.5% | | [Geary](/county/geary.md) | 7 | 0.4% | | [Sumner](/county/sumner.md) | 6 | 0.3% | | [Logan](/county/logan.md) | 5 | 0.3% | ### What stands out for environmental remediation, injection The busiest contractor on these records is **Geocore, INC**, named on 214 of them (11.7%), ahead of Cascade Drilling (194) and Gsi Engineering, LLC (98). The oldest record here was completed in **1980** and the most recent in 2026, and the deepest well on file reaches **1076 feet** — a environmental remediation, injection well drilled by Layne-christensen CO in 1980. ### Plugging records — for environmental remediation, injection **650** of the 1,827 records for environmental remediation, injection carry a plugging report (35.6%), filed on form WWC-5P. The other **1,177** 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 **24** records here completed before 1995, that is exactly what a buyer checks.

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](/privacy.md). ### The records *Environmental Remediation, Injection — « plugging report » reads *yes* where a WWC-5P was filed and a dash where none was, which is NOT a finding that the well is abandoned. A 0 means the driller reported no figure, not a measurement of zero. The legal description is on the record, never on a page.* | WWC-5 | Drilled by | Use | Depth (ft) | Yield (gpm) | Year | Plugging report | |---|---|---|---|---|---|---| | [1057100971](/search.md) |
