About Well Water Testing in Bakersfield
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 Bakersfield Homeowners Should Know
Local Soil Conditions: Bakersfield and Kern County soils include Wasco sandy loam, Cajon loamy sand, and Panoche clay loam — Entisols (Torriorthents and Xerorthents) and Mollisols (Xerolls) formed in alluvial fan, floodplain, and valley deposits from the Sierra Nevada and Tehachapi Mountains. The Wasco series is a well-drained Typic Xerofluvent in the Kern River alluvial fan — deep, coarse-textured sandy loam with rapid to moderately rapid permeability. Panoche clay loam occupies the Tulare Lake bed and western valley floor with heavier texture and lower permeability. Urban expansion in Bakersfield has added extensive Arents and filled land from grading operations. The petroleum-producing Kern River oil fields underlie portions of the metro with hydrocarbon-contaminated subsoils in some industrial zones.
Water Table: The San Joaquin Valley's groundwater has been severely depleted by decades of irrigation pumping; water tables in the Bakersfield area typically range from 50–200 feet below grade depending on location. This deep water table is highly favorable for OWTS drainfield separation requirements. SWRCB requires minimum 5-foot separation from drainfield bottom to groundwater under California's OWTS Policy — easily met in Kern County.
Climate Impact: Bakersfield has a hot semi-arid/Mediterranean climate — one of the hottest cities in the US with average July highs of 100°F and frequent 110°F+ events in summer. Annual rainfall averages just 7.5 inches, almost entirely from November–March. The extreme aridity creates very dry soils that provide excellent drainage during the dry season (April–October) but may limit biological activity. Winter wet periods (December–February) are the primary high-percolation-demand season. San Joaquin Valley tule fog in winter creates cold, damp conditions for weeks at a time.
Signs You Need Well Water Testing
- Annual testing is overdue — all private wells should be tested at least yearly

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