Mail-In Water Testing in San Bernardino, CA

Mail-in water testing gives San Bernardino homeowners, home buyers, landlords, property managers, businesses, rural property owners, and real estate professionals a convenient way to obtain professional laboratory water analysis without scheduling an on-site sample-collection appointment.

5 Microns provides mail-in water testing throughout San Bernardino and San Bernardino County. Customers receive laboratory-approved sample bottles, collection instructions, and Chain of Custody documentation, collect the required samples at the property, and ship them to the designated laboratory for professional analysis.

Testing is available for municipal drinking water, private wells, FHA and VA transactions, bacteria, metals, nitrate and nitrite, hardness, Legionella, and other common water-quality concerns.

What Is Mail-In Water Testing?

Mail-in water testing allows customers to collect their own water samples using laboratory-approved containers and submit them for professional laboratory analysis.

Depending on the selected testing package, analysis may include:

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

Customers may order one individual analysis for a specific concern or select a broader package when several water-quality parameters need to be evaluated.

How Mail-In Water Testing Works

The general process includes:

1. Select the appropriate water testing package.
2. Receive laboratory-approved sample bottles and instructions.
3. Review the collection requirements before sampling.
4. Collect the required water samples.
5. Record the collection date and time.
6. Complete the Chain of Custody documentation.
7. Package the samples according to the supplied instructions.
8. Ship the samples to the designated laboratory.
9. Receive the laboratory report electronically after analysis is complete.

Following the instructions carefully is important because different analyses may have different collection, preservation, temperature, and holding-time requirements.

Municipal Water Testing

Many San Bernardino properties receive water from public water systems.

Independent laboratory testing may still be useful when customers want to evaluate water after it has entered the property and passed through the building’s plumbing.

Customers may request testing because of:

• Older plumbing
• Faucets and fixtures
• Metallic taste
• Cloudy or discolored water
• Sediment
• Plumbing corrosion
• Water quality following repairs
• Concerns about a particular fixture
