Chloride in Water

Chloride occurs naturally in areas of saltwater intrusion. However it can also be present in industrial waste and sewage and therefore can be used as an indicator of pollution.
Taking a water sample
  • The analytical result is only as good as the sample submitted for analysis. Collecting a representative sample is the first step of the analytical procedure.
  • Clean tap thoroughly, including the inlet with a flame or disinfectant wipe.
  • Turn on the tap and allow water to run for a minimum of 2 minutes.
  • Take the cap off the sterile bottle and immediately fill the container.
  • Replace the bottle cap as soon as the bottle is full (leaving a small headspace) and record the site and date of sampling.
  • Deliver to the IEC as soon as possible.
  • Maintain the water samples at 1-5°C if storing overnight.
