What to Know Before You Contact the Lab
Before contacting a certified laboratory, there are a few things to consider when selecting a lab for drinking water testing. Weāve listed the various concepts and procedures itās useful to be familiar with.
Informational vs. Compliance Testing
Compliance testing is a requirement of the Safe Drinking Water Act (SWDA) and applies primarily to public water systems or other agencies that must report their water quality data to comply with U.S. Environmental Protection Agency (EPA) limits. These cases include legal proceedings, regulatory limits, and in some instances, real estate transactions.
Informational testing is for pretty much everyone else. While that means that labs performing informational testing arenāt required to meet EPA approved standardized methods to analyze your samples, itās still a good idea to use laboratories that are accredited and/or certified to test for your analytes of interest.
Accreditation vs. Certification
When it comes to drinking water laboratories, an accredited lab and a certified lab are the same thing. It's just two different ways of saying that an accrediting/certifying agency (like NELAP, the National Environmental Laboratory Accreditation Program) has ensured that the lab meets the requirements to perform the testing they offer.
Additionally, accredited laboratories can also be referred to as state-certified.
Sampling Requirements, Drop-off Procedure, and Turnaround Time
Labs will usually be very straightforward about their requirements and itās your responsibility to pick the lab that best aligns with your needs. However, those requirements are not always easy to understand. Also, some labs may require a minimum number of analytes to test for, which, in turn, can become expensive quickly.
Sampling requirements refers to how the lab would like you to collect your water sample. The lab will inform you when to expect results. How you receive your results depends on the lab (e.g., mailed, emailed, for pickup). Itās worth noting that reports offered directly from the lab are specialized and not easy to read or interpret.
Analyte List
This is a list of analytesāor substances being identified and measuredāthe laboratoryās facilities can test for. Some lists are as simple as a list of items, some offer more detail about each analyte and the testing process or sampling method.
Before initiating contact with a local water testing laboratory, youāll want to know exactly what analytes youād like to test for. Different analytes depend on whether you are a public utility customer or a private well owner, as well as any issues specific to your location.Ā
- Heavy metals (like lead, arsenic, chromium) are always important to test forāno matter the water source
- Well owners will want to test for coliform bacteria and nitrates
- Utility customers will want to test for volatile organic compounds (VOCs)

Between analyte lists, certifications, and the less-than experienced customer service departments, selecting a laboratory on a contaminant-by-contaminant basis can be more cumbersome than it needs to be.

If you are in need of a test that is compliant with the Private Well Testing Act of New Jersey, the state of New Jersey has very specific requirements for home sales and water testing. It is required that lab personnel collect the sample themselves and transport it to the laboratory. Unfortunately, Tap Score cannot assist with this. We recommend contactingĀ EMSL Analytical, Inc. They can perform this kind of testing to meet NJ compliance and should be able to help out.

Where Can I Get My Water Tested for Free?
If you want your water tested for free by a laboratory near you, you should reach out to your local public water utility or health department. Sometimes, free laboratory water testing for a select range of contaminants is available when there are water quality concerns in your region.
For the most part, however, laboratory testing is not free. The equipment and expertise laboratories provide costs a lot of money to maintain. That's why laboratory drinking water test kits cost more than DIY water test strips or color changing kits, which cannot offer the same level of precision or test even a quarter of the contaminants a lab can.
