For Chemical Analysis (At least 1 liter required - or see table below)

​

• Clean plastic or glass containers or bottles are suitable for sampling (Clean, sealed containers is available from the laboratory upon request)

• Keep container closed until is will be filled

• Filling procedures:

  • Potable/Borehole water - open tap and let it flow for a minute.  Open the bottle cap and fill the bottle to the top avoiding any air above the sample.   Important:  Ensure that nothing else comes into contact with the bottle, except for the sample when filling.  Close bottle cap tightly, place in a cooler box to prevent temperature fluctuations (preferably kept below 10C) and send to the lab within 6-24h of sampling time.​

  • Source water - open bottle and rinse twice with sample. Plunge bottle under water at elbow length if possible, away form the inlet.  Fill bottle to the top, avoiding any air above the sample.  Close bottle cap tightly, place in a cooler box to prevent temperature fluctuations (preferably kept below 10C) and send to the lab within 6-24h of sampling time.

• Please label all samples as descriptive as possible - include sampling site and date.

• Please note:

  • incorrect sampling procedures may lead to inaccurate results
