Absence in 100 mL

Total coliforms in systems or collective alternative solutions that supply less than 20,000 inhabitants:

Only one sample, among the samples examined during the month by the person responsible for the system or by a collective alternative water supply solution, may present a positive result

Total coliforms in systems or collective alternative solutions that supply less than 20,000 inhabitants:

Absence of 95% of the 100 mL samples examined during the month by the person responsible for the system or by an alternative collective water supply solution.

Observation

¹Maximum value allowed; ²Indicator of fecal contamination; ³Treatment efficiency indicator.

The established values refer to:

  1. SAI;
  2. SAA e SAC

Been:

  • SAA (water supply system): has a distribuition net.

  • SAC (Collective alternative solution): has not a distribuition net.

  • SAI (Individual alternative solution of water supply for human consumption) is defined as each and every alternative solution of water supply that caters to a single home.
