Mobile Unit Water Testing Requirements

18 AAC 31.500 states that the operator of a mobile food unit or kiosk, except a pushcart, must:

At least annually and before seasonal setup:
Superchlorinate each potable water tank for at least two hours with a 50ppm chlorine solution. (Use bleach (unscented): 1oz (2TBL) per 5 gallons of water);
Drain, thoroughly rinse, and refill the tank.
Submit water samples to a Certified Laboratory for coliform analysis:
Before initial startup and before seasonal startup; and
Every 3 months during operation.
Take the following actions if notified that a water sample exceeds the maximum contaminant level (MCL):
Immediately superchlorinate the tank as described in (1)(a) and (b) above; and
Submit another water sample to a Certified Laboratory for coliform analysis within 24 hours after superchlorination.

All laboratory results must be forwarded to the operator's local ADEC Food Safety and Sanitation Program office.
