Frequently Asked Questions

What are your hours?

Email us at biotechlab@verizon.net for current hours and upcoming closures.  Samples are normally accepted Sunday: noon-7pm, and Monday – Thursday: 7am-7pm.  However, we are open most weekends; occasionally we do close, sometimes with short notice.  So, if you’re planning to deliver sample after 7 PM, email us before collecting it. If you’re planning to deliver a sample Friday or Saturday, email us a day or two ahead to confirm that we will be open and thereby avoid wasting your time and effort (and our resources). For simple logistics questions, email us anytime.  For technical questions and discussion, email us or call Dr. Sismour evenings after 7 PM. From 7 AM to 7 PM, you’ll receive a faster response by email than by a phone call

What test(s) do I need - bacteria or chemical?

The Virginia Department of Health recommends that well water be tested at least annually for bacteria (potability) and nitrate. If you are interested in a water test for your own peace of mind, then start with a bacteria test. If you notice an unusual odor or appearance to your water or are interested in discussing water treatment options, please call us (we do not install water treatment systems). We test for lead, nitrate, nitrite, and other chemicals. Email us with any questions.

What test(s) do I need for a loan, whether for a refinance or a real estate transfer?

All loans require a bacteria test (total coliforms, E. coli ).  Specific loan programs may require chemical tests (lead, nitrate, and nitrite) as well as having a third party collect and deliver the sample (chain-of-custody). Although testing may be specified in your contract, we highly recommend that you confirm the requirements with your mortgage officer so there are no surprises at closing. Email us to request our list of companies that collect samples or for any questions.

What are the water test requirements for a VA Loan (Veterans Affairs)?
  1. The VA loan requires that a third party collect and deliver the sample (chain-of-custody).
  2. All loans require a bacteria test (total coliforms, E.coli ).
    Most VA loans also require chemical tests (lead, nitrate, and nitrite).
  3. Test results are valid for 90 days.

Although testing may be specified in your contract, we highly recommend that you confirm the requirements with your mortgage officer so there are no surprises at closing. Email us to request our list of companies that collect samples or for any questions.

See our Resource list on FAQs/Resources page, first item.

Can I use my own container for the water sample?

The answer depends on the test.

    1. Bacteria test – You will need one of our sterile containers for a bacteria test. Sterile containers are available in our dropbox (24/7).
    2. Chemical tests – You will need one clean disposable water bottle (6 to 12 oz.) for chemical tests. One bottle is enough water for all the tests. You can use your own bottle. If you do not have a bottle handy, we maintain a supply of bottles in a cooler near our dropbox, also available 24/7.

Therefore, if you need a bacteria test and chemical tests, you need to submit two samples.


What is the cost for each test?

A bacteria test costs $50. A lead test costs $50. Other chemical tests cost $25 each. Payment is due at the time of processing. Check, cash, or money order. No credit cards.
