The Guidelines are prepared by SESAI in line with the guidelines created by the Health Surveillance Secretariat (SVS, acronym in Portuguese) that are aimed at indigenous health and sanitation agents linked to the Indigenous Health Care Subsystem.

To meet the demand for monitoring the quality of drinking water, there are partnerships with municipal and regional laboratories coordinated by the state's Central Public Health Laboratory (Lacen, acronym in Portuguese), linked to the State Department of Health, as well as Funasa's laboratories and Reference Units for Water Control and Quality (URCQA, acronym in Portuguese).

To verify potability and assess risks in supply systems and alternatives, the guidelines emphasize the importance of correctly defining sampling collection points for monitoring.

The most effective strategy for ensuring water quality is the combination of selecting the optimal catchment location, subsequent treatment, and systematic quality monitoring.

1. Implementation and standardization of treatment technologies: Adapt the types of treatment required by the legislation and technical regulations in force.

2. Strengthen the operational capacity of water analysis laboratories,
through the constitution of the MQAI laboratory network: Organize the existing laboratory structure for monitoring water quality, as established in current legislation.

The sampling plan to be carried out within each DSEI highlights the importance of analyzing turbidity, pH, color, coliforms, totals and free residual chlorine.

DSESI/SESAI/MS monitoring actions:
a) Designate, in the organizational structure of DSESI/SESAI/MS, a multidisciplinary technical team of water quality in indigenous communities.
b) Coordinate the network of water quality laboratories for human consumption in indigenous communities.
c) Enable financial support for the provision of the necessary infrastructure for water quality monitoring activities.
d) Technically support the Service for Constructions and Environmental Sanitation (Sesani)/DSEIs in the development of water quality monitoring actions in indigenous communities, including on the occurrence of water-borne outbreaks.
e) Evaluate and propose strategies to solve possible health risks related to water quality in indigenous communities.
f) Promote the improvement of the team and instructional instruments.
g) Prepare a quarterly report template to receive information on the water quality monitoring activities developed by DSEI. 

SESAI provides overall financing.

DSEIs are allowed to hire private companies or establish partnerships, through coordination with the partner laboratories of the federative units to carry out analyses.
