The dipperLog 64 is a highly accurate groundwater data logger used by hydrogeologists, hydrologists, environmental technicians, water well contractors and other groundwater professionals. The dipperLog 64 is a reliable and cost effective solution to long and short term monitoring of groundwater levels and temperature in wells, boreholes and open bodies of water.

PFAS (Per- and Polyflouroalkyl Substances) are used in products such as repellent/non-stick coatings or fire retardants. These chemicals are not known to break down and proven very persistent in the environment. Their potential to impact human health has prompted legislations of set maximum acceptable PFAS concentration levels in drinking water.

Numerous health studies have shown that certain PFAS may:

  • Interfere with the body’s hormones
  • Affect the immune system
  • Contribute to birth defects and/or learning disabilities in children
  • Increase cholesterol levels
  • Increase cancer risk
