Dental Unit Waterline Quality Testing Services

Waterlines used in any dental unit that has a water supply, such as syringes and ultrasonic scalers, can become contaminated with biofilm, a coating of microorganisms. To prevent infection, the CDC recommends that dental unit water used in non-surgical procedures is maintained at the same cleanliness standard set for drinking water by the Environmental Protection Agency (EPA). That is, the water must measure less than or equal to 500 colony forming units of heterotrophic bacteria per milliliter (≤500 CFU/mL) of water.

In order to ensure the water in your dental units meet this quality standard, dental unit waterline systems must be regularly maintained with water treatment and monitoring done per the manufacturer’s instructions.
