Here are five critical reasons you should consider professional well abandonment now.

 

1. Protecting Groundwater — Preventing Contamination and Pollutant Migration


When a well is no longer in use, failing to properly seal it creates more than an eyesore — it becomes a serious hazard. Proper water well abandonment for Douglas County, CO, is essential because an unsealed well can allow surface water, chemicals, or other pollutants to seep downward, contaminating groundwater aquifers. Since many homes and private wells in Douglas County depend on these shared aquifers, an improperly abandoned or open well can put water safety for multiple properties at risk.

That’s why Colorado law requires proper sealing and abandonment of unused wells. Under 2 CCR 402216 — the state’s regulation for plugging, sealing, and abandoning wells and boreholes — all unused wells, monitoring wells, or boreholes must be properly abandoned to prevent contamination or unwanted migration of water between aquifers.


By choosing a licensed contractor like Hier Drilling Co, you ensure proper water well abandonment for Douglas County, CO. We seal your well according to state standards, using clean, inert materials and correctly placed grout or cement, protecting groundwater quality for both your property and your neighbors.


2. Compliance with Colorado State Regulations — Avoid Penalties and Liability


Water well abandonment for Douglas County, CO, isn’t just a good idea — it’s the law. According to Colorado Revised Statutes § 37-91-110, wells must be constructed or abandoned in a way that ensures natural protection against pollution of water-bearing formations and prevents contamination.


If a well remains unsealed and someone gets injured — or contamination occurs — the property owner could face legal liability. As the licensed well construction contractor, Hier Drilling Co handles proper notification, planning, and execution of abandonment according to state requirements. Doing it right helps you avoid future liability, regulatory fines, and environmental hazards.


3. Safety and LandUse Protection — Preventing Collapse, Injury, and Unsanitary Conditions


Unused, unsealed wells are safety hazards. Over time, casing can deteriorate; wells can become unstable; open wells can be dangerous for children, pets, and wildlife. They can also collect surface water, debris, or stagnant water — creating unsanitary conditions or risk for unwanted standing water.


Proper water well abandonment for Douglas County, CO, eliminates these hazards. At Hier Drilling Co, we safely plug and seal wells so the site can be used for future land development, landscaping, or construction — without worry of hidden hazards beneath the surface.


4. Protecting Aquifers and LongTerm Environmental Health


Proper water well abandonment for Douglas County, CO, protects more than just your property — it safeguards the long-term environmental health of the entire county. When wells are correctly sealed, they prevent unintended connections between aquifers, reducing the risk of cross-contamination and helping preserve valuable water resources for the community.

State regulations under 2 CCR 402216 mandate that if a well penetrates more than one aquifer, plugs must be placed at each confining layer, or casing must be removed or perforated prior to grouting — to ensure a watertight seal.


By meeting all technical standards, Hier Drilling Co provides professional water well abandonment for Douglas County, CO, ensuring that abandoned wells do not form unintended hydraulic pathways that could threaten groundwater integrity today or in the future.


5. Preserving Property Value and Future Development Options


If you plan to sell, build, or develop land in Douglas County, an abandoned but unsealed well can reduce property value or complicate future permits. Real estate buyers, developers, or lenders often view unsealed wells as liabilities — both for safety and environmental compliance. 

By investing in proper water well abandonment for Douglas County, CO, now, you protect your land’s market value and usability. Once sealed by professionals like Hier Drilling Co, your property will be ready for safe development, landscaping, or resale — without hidden complications or potential liability.

At Hier Drilling Co, we have the knowledge, certifications, and local experience to manage water well abandonment for Douglas County, CO, effectively. Here’s how we do it:


  1. Assessment & Documentation — We review your well records (or lack thereof), determine aquifer types, depth, and casing, and plan the appropriate sealing method per regulations. 
  2. Licensed Professionals & Proper Materials — Under Colorado law, only licensed water well construction contractors may perform abandonment — especially for wells that penetrate multiple aquifers. We use clean, inert backfill materials, grout, or cement as required. 
  3. Plugging, Sealing & Grouting — For wells in confined aquifers or multipleaquifer wells, we place proper cement plugs at confining layers, remove or perforate casing when needed, and ensure no hydraulic connection between aquifers. For unconfined aquifers, we fill to the static water level with sand or gravel, then backfill with clay, cement or grout to the surface. 
  4. Surface Restoration & Documentation — After sealing, we cap or permanently cover casing and restore the surface ground — making the site safe and ready for future use. We also provide documentation confirming compliance.
