Water Well Location Map According to States

One of the most important things to do before commencing construction on a private well is to select the well location. All the states in the U.S. have laid out detailed guidelines on where to construct a well on your property.

In this article, we will discuss the water well location map in the following 13 major states.

  1. Texas
  2. Colorado
  3. New Mexico
  4. Utah
  5. California
  6. Michigan
  7. Idaho
  8. Florida

Water Well Location Map According to States 

It is important to highlight that all the 13 states mentioned above have outlined guidelines for locating a water well. These laws and directions are almost the same in all the states. The purpose of laying out these directions is to minimize contamination from other structures on your property like a septic system, chemical storage, animal waste storage, and other sources.

You also need to avoid fetching too much underground water from neighbors’ properties and avoiding contamination from an old well. It is a complicated process, and it is best if you hire a certified well driller to make this plan for you, even if your state allows drilling well on your property.

Minimum Distance from Contamination Sources

Let’s check out the minimum required distances.

Contamination Source Minimum Distance from Water Well (Feet)
Agricultural chemical or fertilizer storage or preparation area 150
Animal waste lagoon or manure storage 150
Animal or poultry yard 50
Brine wells or injection well 150
Building or projection thereof 3
Cemetery and graves 50
Cesspool 50
Chemical Storage 150
Contaminant plumes 300
Drain field 50
Dry well 50
Footing drain 10

 Fuel/chemical storage tanks – Underground or above grade and associated piping 

depot/tank farm 300
1,100 gal. or larger, without secondary containment 300
1,100 gal. or larger with secondary containment 50
less than 1,100 gal 50
located in a basement, regardless of size 50
Grease trap 50
Kennel 50
Landfill or dump sites (Active or Inactive) 800
Liquid waste draining into the soil 50
Metering station for pipeline 300
Municipal wastewater effluent or sludge disposal area (land surface application or subsurface injection) 300
Municipal wastewater lagoon 300
Oil or gas well 300
Other wastewater handling or disposal unit 50
Petroleum product processing or bulk storage 300
Pipeline for gas, oil 50
Privy/outhouse 50
Seepage pit 50
Septic Tank 50
Septage waste (land application area) 800
Sewage holding tank 50
Sewage lagoon serving a single family dwelling 50
Sewage lagoon effluent – land application area 50
Sewage or liquid waste draining into soil 50
Sewage pump chamber, transfer station, or lift station 50
Sewers 10-50 feet
Sump pit 10-50 feet
Surface water (lake, river, stream, pond, ditch, etc.) 10
Unfilled space below ground surface (except an approved basement, basement offset, or crawl space beneath single family dwelling) 10

There might be some variations in these distances from one state to another. Hence, it is best to consult the relevant department in your area before you submit a well permit.

Deviations

Local health and water authorities can issue deviations in special cases upon request. The deviation must be requested in writing prior to well construction. You will need to submit the following documents for a deviation approval.

  • Why the rule cannot be met
  • Water well location
  • Distance to the source of contamination
  • Detailed site plan
  • Geologic conditions
  • Neighboring well details
  • Proposed well construction plan

Final Words

It is in your best interest to consult with the local authorities and certified well drillers before submitting a permit for approval. Local authorities hold the right to bar you from using well water and impose penalties if you are found violating the rules.
