Water Quality Analysis — Industrial Processes, Cooling Towers and Potable Water in Brazil
Water quality directly impacts industrial process reliability, equipment lifespan and public health compliance. ES Engenharia collects samples and coordinates accredited laboratory analysis covering physicochemical and microbiological parameters for boiler feedwater, cooling towers, process water and potable water systems in Espírito Santo.
Water quality in industrial operations — why it matters and what the law requires
Poor water quality causes scale, corrosion and biofouling in boilers, heat exchangers and cooling towers — reducing efficiency, triggering unplanned shutdowns and creating Legionella risk in recirculating systems. Brazilian ANVISA Resolution RDC 60/2016 and ABNT NBR 14605 set mandatory monitoring requirements for cooling towers.
For potable water, Ministerial Order GM/MS 888/2021 defines the microbiological and physicochemical parameters that must be met in self-supply systems (artesian wells, reservoirs) used in workplaces and commercial buildings. Non-compliance exposes companies to Health Surveillance notifications and fines.
ES Engenharia collects water samples following chain-of-custody protocols and coordinates analysis at accredited laboratories. We deliver a technical report with ART CREA-ES that specifies parameter exceedances, their probable causes, and corrective treatment recommendations compatible with Brazilian and international standards (ASHRAE 188, CTI, CONAMA 357).

Frequently asked questions about water quality analysis
When is water quality analysis mandatory? +
Analysis is mandatory in several situations: residential and commercial condominiums with their own reservoir (municipal Health Surveillance requirement); food and beverage industries (MAPA/ANVISA registration); hospitals and clinics (ANVISA RDC 63/2011); companies with artesian wells supplying water to workers (NR-24 and Ministerial Order GM/MS 888/2021); and establishments with swimming pools (Pseudomonas and coliform analysis). In buildings with PMOC, cooling tower water analysis is also mandatory due to the Legionella risk.
Which parameters are analysed in water quality testing? +
For potable water (Ministerial Order GM/MS 888/2021): microbiological — total coliforms, Escherichia coli (E. coli); physicochemical — turbidity, apparent colour, pH, free or combined residual chlorine, fluoride; and where applicable — nitrate, iron, manganese, aluminium, lead, arsenic and pesticides. For swimming pools: additionally Pseudomonas aeruginosa, Staphylococcus aureus, turbidity and pH.
How often should water be tested? +
The frequency depends on use: for self-supply systems (well or reservoir), Health Surveillance typically requires semi-annual or annual analysis. For food industries, the frequency may be monthly. Cooling towers require monthly monitoring (temperature) and quarterly analysis (Legionella). For swimming pools, microbiological analysis should be semi-annual and physicochemical analysis more frequent. A specific monitoring plan must be developed according to the risk profile of each facility.
Can a water quality report be used for environmental licensing? +
Yes. When an artesian well or surface water intake is part of the company's environmental licensing, the water quality report is one of the documents required by environmental agencies (IEMA in Espírito Santo). The report must be issued by an accredited laboratory and signed by a technical manager with ART.
What happens if the water quality report fails? +
If results exceed the limits of Ministerial Order GM/MS 888/2021, the company must immediately cease using the water for potable purposes, identify the contamination source, carry out treatment (hyperchlorination, UV, filtration) and collect a new sample after treatment to confirm compliance. Health Surveillance must be notified in cases of contamination in collective supply systems.
Does ES Engenharia perform sampling at artesian wells? +
Yes. We perform technical sampling at artesian wells, building reservoirs, internal consumption points and water treatment systems for industries and condominiums throughout Espírito Santo. The report includes all mandatory parameters of Ministerial Order GM/MS 888/2021 and is signed with ART by the Technical Manager.
