is important to check with your bank or lender to see if they have specific water testing requirements. Among the most common is a coliform bacteria test, but some Federal lenders may also request a screening for lead, nitrite, and nitrate. Please check with your lender for more information, and allow 6-10 working days for your tests to be performed.
Total Coliform Bacteria are present in the environment and feces of all warm blooded animals and humans. Total Coliform Bacteria are unlikely to cause illness, however their presence in drinking water indicates that disease causing organisms (pathogens such as E. Coli) could be in your water. If Total Coliform Bacteria is present, the laboratory will also test the sample for E. Coli. Total Coliform bacteria testing costs $22, and the sample must be returned to the laboratory within 24 hours of collection.
Lead (symbol Pb) is a metal found in natural deposits, and is primarily from materials and components associated with service lines and home plumbing. Lead can be toxic to the kidneys and nervous system, and can cause serious health problems, especially for pregnant women and young children. For more information, visit the Washington State Department of Health or the Environmental Protection Agency‘s pages about lead in drinking water. A lead analysis costs $23, and takes 6-10 working days. If done in conjunction with copper, a discounted price of $36 applies.
Nitrite and Nitrate are nitrogen–oxygen chemical units that combine with various organic and inorganic compounds. Nitrite has the molecular formula NO2. Nitrate is a polyatomic ion with the molecular formula NO3. It is a chemical found in most fertilizers, manure, and liquid waste. For more information on Nitrate, visit the Washington State Department of Health. Nitrite/Nitrate testing costs $35, and the sample must be returned to the laboratory within 48 hours of collection.

HOW TO COLLECT A SAMPLE FOR METALS/INORGANICS
Stop by our office or drop box location, and pick up one or more collapsible cube container(s) along with an instruction sheet and a Chain of Custody form. Please do not open
container(s) until sample is to be taken.
Remove cap and inflate cube container completely by blowing into the opening. As this container is for inorganic tests, you will not contaminate the sample by blowing into the container.
If sampling from inside a residence, remove all
attachments and/or filters from the faucet before taking the sample. Turn on cold water only. Do not take sample from a hose or hot water faucet.
Make sure cap is secured tightly. Label container(s) with name, address, or other identifier. Keep sample(s) in the refrigerator or on ice until returned to the lab.
Complete the Chain of Custody / Water Sample Information form with name, address, phone number, date and time of collection, location and source of sample(s), analysis requested, and public system information if required. Standard turn-around time for results is 6-10 working days from receipt of sample, unless arrangements are made (this time may vary depending on the analysis performed).
HOW TO COLLECT YOUR TOTAL COLIFORM BACTERIA SAMPLE
Use an inside faucet. Use faucets that have separate hot and cold handles. Bath fixtures are a good choice. Avoid swivel taps, such as those found on kitchen sinks, as these faucets have a greater chance of harboring bacteria. Remove all attachments from the faucet, including aerators, screens, hoses and/or filters.
Turn on cold water only and let it run with a steady stream for at least 5 minutes. Before collecting the sample turn the water down so that the stream is about the width of a pencil, then let the water run for one minute.
When you are ready to take the sample hold the bottle near the bottom and unscrew the cap. Avoid touching the edge of the cap, and avoid splashing it as the sample is collected. Do not touch the inside
of the cap or bottle.
Fill the water to the 100 mL line, do not allow it to overflow.
Do not rinse the bottle before taking sample. The bottle contains a small amount of white powder (dechlorinating agent) that is a necessary chemical for the analysis.
Replace the lid as soon as the bottle is filled and removed from the flow. Keep sample in the refrigerator or on ice until it is returned to the lab. Samples must be tested within 24 hours of collection.
Fill out the lab slip with name, address, phone number, time and date of collection.
