We will need a minimum of 1L of water to give to the Lab.
Make sure that you use either a sterilized sample bottle we have available if you need or alternatively you can buy a 1.5L bottle of water from a reputable brand like 62 Waters or Bonaqua. You can then open and empty the bottle when you take the sample, fill it with no air gap and immediately seal it again.
Lab testing typically takes 2 to 3 weeks to complete.
