How Mail-In Water Testing Works

Mail-in testing allows customers to collect water samples at their property using appropriate laboratory containers.

The general process includes:

1. Select a testing package. Identify the water source and contaminants to be evaluated.
2. Complete payment. Orders are processed after payment is received.
3. Receive the sampling kit. Laboratory-approved bottles and instructions are supplied for the selected analyses.
4. Collect the samples. Follow the collection procedures for each laboratory test.
5. Complete the Chain of Custody. Record the sampling locations, dates, times, and requested analyses.
6. Package the samples. Follow the supplied preservation and shipping instructions.
7. Ship to the laboratory. Send the samples to the designated laboratory within the applicable holding times.
8. Receive your results. The laboratory report is generally delivered electronically after analysis is complete.

Different contaminants require different collection and handling procedures. Customers should review the instructions before collecting any samples.

Why Choose Mail-In Water Testing in Visalia?

Mail-in testing eliminates the need for a separate field visit when customer-collected samples are appropriate for the testing objective.

This can be especially convenient for:

• Private well owners
• Rural homeowners
• Agricultural-area residences
• Farm and ranch properties
• Home buyers
• Landlords and property managers
• Customers testing a specific faucet
• Commercial property owners
• Customers outside major urban service areas

The samples are still submitted for professional laboratory analysis.

Mail-in testing can also make it easier for customers to arrange sampling around their own schedules, provided they comply with the laboratory’s holding-time and shipping requirements.

Private Well Water Testing in Tulare County

Private wells supply drinking water to some rural residences and agricultural properties throughout Tulare County.

Unlike public water systems, private wells generally require property owners to arrange their own water-quality monitoring.

Common laboratory analyses for private wells include:

• Total Coliform
• E. coli
• Nitrate
• Nitrite
• Arsenic
• Lead
• Copper
• Iron
• Manganese
• Hardness

Testing may be appropriate for routine monitoring, real estate transactions, financing requirements, or specific groundwater-quality concerns.

For more information, visit Well Water Testing California.

Nitrate Testing for Central Valley Groundwater

Nitrate is an important consideration for some private wells in California’s agricultural regions.

Potential sources of nitrate in groundwater include agricultural fertilizers, animal waste, septic systems, and other activities.

Private well owners may request nitrate testing when:

• Purchasing a rural property
• Monitoring an existing well
• Evaluating household drinking water
• Investigating agricultural groundwater concerns
• Completing certain real estate transactions
• Meeting applicable financing requirements

Elevated nitrate concentrations in drinking water can pose health risks, particularly for infants.

Nitrate generally cannot be detected through taste, smell, or appearance.

Laboratory analysis is necessary to determine the concentration in the submitted sample.

Arsenic Testing for Private Wells

Arsenic may occur naturally in groundwater due to geological conditions.

Private well owners may request arsenic analysis when:

• A well has never been tested for arsenic
• Previous results identified arsenic
• Purchasing a property
• Investigating groundwater contamination concerns
• Conducting a broader private-well evaluation

Arsenic generally cannot be identified through taste, odor, or appearance.

Laboratory testing provides a measured concentration for the submitted sample.

Arsenic analysis may be ordered individually or as part of an appropriate metals testing package.

Bacteria Testing for Private Wells

Bacteria testing commonly includes Total Coliform and E. coli.

Testing may be requested for:

• Routine private well monitoring
• Real estate transactions
• Suspected contamination
• Well repairs
• Well disinfection follow-up
• Flooding or surface-water intrusion concerns
• Certain financing requirements

Bacteria samples require sterile laboratory containers.

Customers should avoid touching the inside of the bottle or cap and should never rinse a sterile sampling bottle.

Because microbiological samples have relatively short holding times, collection should be scheduled to allow prompt delivery to the laboratory.

Municipal Drinking Water Testing

Many Visalia properties receive drinking water from public water systems.

Customers may still request independent laboratory testing to evaluate water collected from a particular fixture.

Common concerns include:

• Lead
• Copper
• Metallic taste
• Plumbing corrosion
• Sediment
• Discoloration
• Hardness
• Mineral deposits
• Water quality following plumbing repairs

Water may interact with building plumbing after entering the property.

Laboratory results apply to the submitted sample collected from the identified sampling location and time.

For additional information, visit Drinking Water Testing California.

Testing Water From a Specific Faucet

Mail-in testing can be useful when the concern involves one particular fixture.

Customers may collect samples from:

• Kitchen faucets
• Bathroom faucets
• Refrigerator water dispensers
• Drinking fountains
• Apartment-unit fixtures

• Other designated locations

The sampling location should be clearly identified on the Chain of Custody documentation.

Results from one fixture should not automatically be interpreted as representing every fixture throughout the property.

Lead and Copper Testing

Lead and copper testing may be appropriate when customers are concerned about plumbing materials or fixtures.

Potential concerns include:

• Older plumbing
• Service lines
• Faucets and fixtures
• Metallic taste
• Blue-green staining

• Water that has remained stagnant
• Plumbing repairs

Different testing objectives may require different collection procedures.

For example, a first-draw sample may serve a different purpose from a sample collected after flushing.

Customers should follow the specific laboratory instructions for their selected analysis.

Iron and Manganese Testing

Iron and manganese testing may be useful when customers observe:

• Rust-colored staining
• Black deposits
• Sediment
• Metallic taste
• Discoloration
• Mineral accumulation

Laboratory analysis provides measured concentrations for the submitted samples.

Customers may order these analyses individually or as part of a broader water-quality package.

Water Hardness Testing

Hardness testing measures the concentration of hardness-producing minerals in water.

Customers may request testing because of:

• White mineral deposits
• Scale buildup
• Water-heater deposits
• Spots on glassware
• Reduced soap performance
• Showerhead buildup

Hardness analysis may be ordered individually when mineral scale is the primary concern.

Water Testing for Agricultural-Area Residences

Tulare County includes extensive agricultural activity and rural properties where private wells may be used for household drinking water.

Mail-in testing can be particularly convenient for:

• Farm residences
• Ranch homes
• Rural rental properties
• Agricultural-area housing
• Employee residences
• Private wells

Customers should identify whether the water is intended for drinking, irrigation, agricultural production, or another use.

Different water uses may require different laboratory analyses.

Water Testing After Well Repairs

Private well owners may request laboratory testing following:

• Well pump replacement
