Frequently Asked Questions?
Can I test for everything?
 Yes, but there are hundreds of water tests and it would cost thousands of dollars. Coliform bacteria, nitrate, arsenic, and lead tests cover most common health issues in drinking water. Iron is a nuisance, not usually a health issue, and is often found in well water.
How much does it cost for a water test?
 Call AddyLab for current fee information (360) 750-0055.
How long does water testing take?
The turn around time for coliform bacteria test is one day. Nitrates and fluoride are tested once a week. Other tests, like the arsenic and lead, may require 8-10 working days. Extra costs may be paid to rush samples to 4-6 days.
How do I know if the water from my well is safe to drink?
Only by laboratory testing for bacteria or chemicals can you assure your water is safe. If coliform bacteria are present, dangerous bacteria and viruses may be in your drinking water. In the Pacific Northwest another concern is the naturally occurring contaminate arsenic. The only way to determine if you have a safe level of arsenic, or any arsenic at all, is to test your water.
What causes rotten-egg smell from my well water?
 Hydrogen sulfide, the rotten-egg smell, may be caused by sulfate-reducing bacteria, water heaters, natural sources or contamination.
