Frequently Asked Questions

1. How do I know what tests I need?

If you are questioning the quality or safety of your drinking water, you probably already have an idea of the possible contaminates. The following is a guide to selecting tests. Also, be sure to check the list of common contaminants.

Conditions or Nearby Activities:

Test for:

Recurring gastro-intestinal illness

Coliform bacteria

House built before 1986 or live in an older neighborhood


Corrosion of pipes, plumbing

pH, lead, iron reducing bacteria

Nearby areas of intensive agriculture

Nitrates, pesticides, coliform bacteria

Coal or other mining operations nearby

Metals, pH

Gas drilling operations nearby

Chloride, sodium, barium

Dump, junkyard, landfill, factory, gas station, or dry-cleaning operation nearby

Volatile organic compounds, total dissolved solids, pH, sulfate, chloride, metals

Odor of gasoline or fuel oil, and near gas station or buried fuel tanks

Volatile organic compounds

Objectionable taste or smell

Sufate reducing bacteria, sulfate, metals

Stained plumbing fixtures, laundry

Iron, copper, manganese

Salty taste and seawater, or a heavily salted roadway nearby

Chloride, total dissolved solids, sodium

Scaly residues, soaps don’t lather


Rapid wear of water treatment equipment

pH, alkalinity, hardness


Well Water:

If you get your water from a private or shared well, you should have your water tested annually. Well water is susceptible to many contaminants including bacteria, nitrates and Volatile Organic Compounds (VOCs). The potentially dangerous contaminates can go unnoticed for years unless you test your water. Some states like Wisconsin have very specific regulations for private wells, but even if your state does not require testing, you should still test your well water on a regular basis.

2. I have city water. Do I still need to test my water?

Most people receive water from a municipal, community or public water supply also known as city water. Public water supplies are required to test their water on a regular basis by the EPA and make the results available to you in a Consumer Confidence Report (CCR). To find your local drinking water information click here. Even if you receive your water from a public water supply, you should still consider testing your drinking water for a variety of reasons, including:

If your home was built before 1986 or if you live in an older neighborhood you should test for Lead. Lead problems in Chicago, Milwaukee and Flint Michigan have raised this issue to the top of the list of drinking water concerns.

If you are experiencing routine gastrointestinal problems you may want to test for Bacteria

Or if you suspect a broken pipe or just do not trust the results from your public water supply you may want to test your water for a variety of parameters.

3. What is the difference between your tests and “free water tests” offered from Home Depot and other companies?

Nothing is free. Those free tests are often performed by unskilled individuals using test strips or other inaccurate methods. Most of these companies are using the free water test as a way to get you to buy their expensive water treatment systems. Suburban Labs employs trained chemists and microbiologists and uses EPA approved methods in a state-of-the-art laboratory. We only test water quality and will never try to sell you other products.

4. Will you tell me if my water is safe?

The report will identify any contaminants and if they are present at a level above the Maximum Contaminant Level (MCL) as defined by the U.S. Environmental Protection Agency. If a contaminant is found above the MCL, the water should be considered unsafe.

5. How do I order a drinking water test kit?

Ordering a test kit is fast and easy. Simply add the test to the cart and follow the on-screen instructions to purchase. We will need your mailing and billing address and you will need to select how you would like to receive the test kit. You can have it shipped to you or you can pick up the kit from our office.

6. How long does it take to get the water test kit and the final report?

Test kits are usually mailed within a week, and you will have the option to pick up the kit from one of our offices. Most reports are emailed to you within 10-15 business days, however some reports may take longer. Expedited testing is not provided and turnaround time is dependent on the capacity of the laboratory.

8. How do I return the samples to your lab?

You are responsible for the cost and care of returning samples to the laboratory. If using a commercial carrier such as UPS or FedEx, we recommend packing the samples in bubble wrap or other packing material to minimize breakage. Samples for Coliform Bacteria must be returned with 24 hours of sample collection. It is essential that samples are returned ASAP after collection. There are no refunds for damaged shipments or samples received past holding time.
