Water quality for spraying operations

Key points

  • Poor water quality can adversely affect many products. Always consult product labels and the manufacturer’s technical information about water quality requirements.
  • Water testing should be done on a regular basis when using bore water, water from streams and rivers, reticulated (piped) water sourced from ground water, and water stored in unlined dams or concrete tanks.
  • Water tests should analyse the following to be useful: pH, total hardness (including a measure of bi-carbonate levels) and total dissolved salts (TDS) or salinity (electrical conductivity).
