Observation

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

The established values refer to:

• 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.
