Mail-In Water Testing in Stockton, CA
Mail-in water testing gives Stockton homeowners, home buyers, private well owners, landlords, property managers, agricultural property owners, businesses, 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 Stockton and San Joaquin County. Customers receive laboratory-approved sample bottles, collection instructions, and Chain of Custody documentation, collect the required water 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 those samples to a professional laboratory.
Depending on the selected testing package, laboratory analysis may include:
Customers may choose an individual analysis for one specific concern or select a broader testing package when several water-quality parameters need to be evaluated.
How Mail-In Water Testing Works
The general process includes:
- Select the appropriate water testing package.
- Complete payment before the testing kit is shipped.
- Receive laboratory-approved sample bottles, collection instructions, and Chain of Custody paperwork.
- Review the instructions before collecting any samples.
- Collect the water samples as directed.
- Record the collection date and time.
- Complete and sign the Chain of Custody documentation.
- Package the samples according to the supplied instructions.
- Ship the samples to the designated laboratory.
- Receive the laboratory report electronically after analysis is complete.
Following the collection and shipping instructions carefully is important because some analyses have specific sample-handling, temperature, and holding-time requirements.
