About Well Water Testing in El Paso

Well water testing analyzes your private well water for contaminants including bacteria, nitrates, heavy metals, pH levels, and other substances that can affect health and taste. The EPA does not regulate private wells — the responsibility falls entirely on the homeowner. An estimated 23% of private wells have at least one contaminant exceeding health-based standards according to the USGS. Annual testing is recommended at minimum, with additional testing after flooding, nearby land use changes, or if you notice changes in taste, color, or odor. Basic tests cover coliform bacteria and nitrates — the two most common and dangerous contaminants in well water. Comprehensive panels add testing for lead, arsenic, manganese, iron, hardness, pH, total dissolved solids, volatile organic compounds, and pesticides depending on your region and local geology. Results typically take 5-14 business days from a certified laboratory. If contaminants are found, treatment options range from simple point-of-use filters to whole-house treatment systems depending on what is detected and at what concentration.

What El Paso Homeowners Should Know

Local Soil Conditions: El Paso's soils are dominated by Canutillo loam, Pajarito fine sandy loam, and Harkey silt loam — well-drained Aridisols and Entisols formed on alluvial fans and floodplain terraces of the Rio Grande in the Chihuahuan Desert. The Canutillo series features calcareous loam over a calcic horizon (caliche) at 20-40 inches — the dominant soil on the eastern valley floor. The Pajarito series on upper alluvial fans and bajada slopes has loamy-skeletal profiles with strong calcic horizon development (petrocalcic layers in many locations) that prevents drainage. Franklin Mountain piedmont soils include Anapra and Hueco series — shallow, rocky, gravelly profiles over limestone bedrock within 12-24 inches. The Rio Grande floodplain contains Glendale and Vinton silty clay loams with poor drainage.

Water Table: Water table depth is highly variable. In the Hueco Bolson (the primary aquifer under El Paso) water tables have dropped significantly due to decades of pumping, with the regional water table now at 50-150 feet below grade in most of the city. However, the Rio Grande floodplain has shallow perched water tables at 3-10 feet due to irrigation infiltration and river seepage. Far East El Paso developments on bajada slopes typically have deep water tables that are not a drainfield design constraint, but caliche layers are the primary limiting factor.

Climate Impact: El Paso has a hot desert climate (Köppen BWh/BSh) with low humidity, intense sun, and very low annual precipitation of 9.5 inches. Summers are intensely hot with temperatures frequently exceeding 100°F. The monsoon season (July-September) brings 40-50% of annual rainfall in scattered heavy thunderstorms. Winters are mild with occasional freezes. The arid climate reduces soil saturation risk for drainfields but also means native soil biology is less robust — septic tank bacterial populations can be stressed by low moisture conditions and temperature extremes.

Signs You Need Well Water Testing

  • Annual testing is overdue — all private wells should be tested at least yearly
  • Water has a new or unusual taste, odor, or color
  • Recent flooding or heavy rainfall near the well
  • Nearby construction, agriculture, or land use changes
  • Household members experiencing unexplained gastrointestinal illness
  • Buying or selling a property with a private well

The Well Water Testing Process

  1. 1 Contact a certified water testing laboratory or local health department for test kits
  2. 2 Collect water samples following the lab's instructions for each test type
  3. 3 Submit samples to the lab within the required holding time (usually 24-48 hours)
  4. 4 Lab analyzes samples and compares results to EPA health-based standards
  5. 5 Receive a detailed report showing contaminant levels and whether they exceed guidelines
  6. 6 If issues are found, consult with a water treatment professional for remediation options

Frequently Asked Questions — El Paso

Does El Paso have city sewer or do most homes use septic?
Most of the incorporated city of El Paso is served by municipal sewer through El Paso Water Utilities. Septic systems are primarily found in unincorporated El Paso County communities such as Horizon City, Clint, Anthony, San Elizario, Fabens, and the Lower Valley colonias. If you are purchasing property outside city limits or in an unincorporated community, confirm the wastewater service type before completing the transaction.
What is caliche and how does it affect septic systems in El Paso?
Caliche is a hardened calcium carbonate layer that forms in desert soils when precipitation dissolves calcium from the soil and re-deposits it as rock-hard carbonate at a consistent depth. In El Paso County, caliche can be encountered as shallow as 18-24 inches below the surface. A cemented petrocalcic layer physically blocks effluent from percolating downward, making conventional gravity drainfields impossible in that location. Site evaluators probe and describe the caliche depth and hardness to determine if a lot can support a conventional system or requires an engineered alternative.
How much does septic pumping cost in El Paso?
Septic tank pumping in the El Paso area ranges from $200 to $375 for a standard 1,000-gallon residential tank. El Paso's lower cost of living and generally lower density of septic-dependent homes compared to eastern Texas metros keeps prices competitive. Service providers serving Horizon City and the Lower Valley communities typically charge in this range.
Are there special septic rules near the Rio Grande in El Paso County?
Yes. Properties near the Rio Grande and within the IBWC flood control levee system require coordination with the International Boundary and Water Commission before any ground disturbance including septic system installation. The TCEQ also enforces setbacks from the Rio Grande as a surface water body. Given the transboundary nature of the Rio Grande — shared with Mexico — wastewater discharges affecting the river are subject to international scrutiny under the 1944 Water Treaty.
What are colonias and how do they relate to septic systems in El Paso County?
Colonias are unincorporated border communities that historically developed without adequate infrastructure, including water and wastewater service. Many Lower Valley colonias in El Paso County had no septic systems — residents used outhouses or illegal surface disposal. State and federal programs have invested billions since the 1990s to bring colonias up to code, installing community sewer systems or proper OSSF where central sewer is not feasible. The Texas Water Development Board and TCEQ coordinate colonia wastewater improvement programs.
