Knowing when your well needs professional decommissioning is critical for protecting your property and the groundwater supply that many Douglas County, CO residents depend on. At Hier Drilling Co., we understand that well abandonment for Douglas County, CO is a regulated process governed by the Colorado Division of Water Resources, and skipping it can lead to serious environmental and legal consequences. This article covers five clear signs that your well may need professional closure services now. Call us at (303) 688-3012 to speak with our team today.


1: Your Well Is No Longer in Use


An inactive well still poses a risk, even if it never produces water again. Unused wells can act as a direct pathway for surface contaminants to reach underground water supplies. Colorado rules require that all unused and unpermitted wells be properly abandoned, including water wells and observation wells.


If your property has a well that has sat dormant for years, it may already be out of compliance. Professional well closure in Douglas County is often required even when a well has simply been left unused for an extended period, and waiting longer only increases your exposure to regulatory penalties.


2: Your Water Shows Changes in Quality


Contaminated well water is a serious warning sign. Changes in your water's color, odor, or taste may indicate that the well casing has failed or that nearby contaminants have entered the groundwater. Once contamination is confirmed through testing, professional closure may be the only safe path forward.


Improperly sealed wells can allow nitrates and other harmful substances to migrate into shared aquifers that serve surrounding Douglas County properties. If you recognize this warning sign, pursuing proper well closure promptly can prevent further contamination of your water supply.


3: The Well's Structure Is Deteriorating


A well with physical damage cannot protect the aquifer below it. The following conditions can all allow pollutants to enter the groundwater system and create physical safety hazards for people and livestock on your property:


Cracked or corroded casing is one of the most common forms of structural failure we encounter during inspections. A missing well cap leaves the interior of the well exposed to surface debris, animals, and contaminants with no barrier in place. A sunken or shifted casing compromises the integrity of the well seal and can no longer reliably prevent contamination from migrating downward.


4: You Are Redeveloping or Subdividing Your Property


Land use changes frequently trigger well closure requirements. If you are building new structures, connecting to a municipal water system, or subdividing a parcel in Douglas County, an existing private well may need to be properly decommissioned before permits are issued.



Failing to address an old well during redevelopment can create title complications and delay your project. In these situations, proper decommissioning must be completed and documented before work can proceed.


What Happens If You Skip Professional Well Abandonment?


Improper abandonment can create lasting problems for property owners. An improperly sealed well may allow surface water, agricultural runoff, or septic system effluent to contaminate the aquifer that neighbors and nearby communities rely on. Beyond environmental harm, the property owner may face regulatory violations and potential legal liability.


The Colorado Division of Water Resources requires a formal closure report to be filed after a well is properly plugged and sealed. Our professional well closure services in Douglas County, CO ensure all documentation is filed correctly and that the work meets state construction standards.
