  1. What happens next?
    Once payment is received, ALS will post sterile water containers to your address. When you receive them please follow instructions when filling them up with water and deliver or post to the lab. You will receive your certificates within 7-10 working days.
  2. Why have I received 2 water bottles?
    Your water sample will be sent to the Microbiological Lab and Chemistry Lab for testing, we therefore need 2 separate containers to perform the testing.
  3. I have received certificate of analysis only for microbiological tests, the chemical tests are missing, when will I receive them?
    Microbiological testing takes 2-3 days to complete and chemical 7-10 days. You will receive 2 separate certificates for your water sample. Once you received your microbiological certificate, the chemical one will follow within the week.
  4. How will I know if my water is okay to drink?
    We provide a list with guidelines for your results so that you can interpret them yourself. But if you are unsure what your results should be or have a question please contact us directly and a member of staff will be happy to answer them for you.
  5. Can you tell me what water filtration system I should use?
    No, but you can bring your results to a company dealing with water filtration systems and they will suggest a suitable treatment system.
  6. I have paid for and sent my water for testing 2 weeks ago and haven’t heard anything back?
    Please give us a call to make sure we have the correct email address for you, as your results will be automatically sent to you by email once they are available.
  7. I have a water filtration unit installed and want to check if it’s working. What should I do?
    We suggest you take 2 water samples: before and after the treatment unit and compare the results.
  8. How often should I test my water?
    There are no specific requirements but we suggest you check your water yearly or as soon as you notice any abnormality or change in water quality/taste/colour.
  9. My plumber advised I should test my water, why is that and what should I test it for?
    If your plumber noticed your pipes are getting blocked or corroded he will most likely suggest you check your water hardness as lime scale is a common cause of blockages in the plumbing systems and appliances. He might also suggest to test for Langelier Index which would be an indicator of corrosion.
