The quality of consumed waters in Professor José da Silveira Netto City University from the
drinkers of the (local) was subjected to qualitative analysis, in which 15 samples from 12
drinking fountains and 3 deep wells located in the basic and professional sectors (ETA)
Campus were collected respectively for physic-chemical water analysis, it was analyzed the
following of ions and parameters: pH, total hardness, conductivity, total solids dissolved,
turbidity, chloride, fluoride, sulfate, total iron, sodium, potassium, calcium, magnesium,
ammonium, nitrate and total alkalinity. The sedimentary packages that accumulate
groundwater in the study area are three sets of trainers major aquifers: Barreiras, Upper and
Lower Pirabas. The ETA well 3 is the one which has a larger volume of water. This water is
treated and destined to points of consumption on campus UFPA whose flow is 200 m³/h.
Based on the physic-chemical results achieved in the wells and troughs in the study area, it is
observed that there are restrictions for human consumption according to the Decree n.°
2914/2011 of the Ministry of Health and OMS for the parameters iron and turbidity.
However, if we consider only the troughs for the classification of water quality, it appears that
75% of the samples show good water quality, with no further restrictions in general for human
consumption. Regarding the hardness of the water fountains and wells exhibit similar patterns
of classification, ranging from "Moderately Hard" to "Hard" (smaller amount in both), in
which all had values within the limit established by Ordinance No. 2914 MS up to 500 mg/L
CaCO3. According to Art 3 of CONAMA Resolution No. 396/2008, the groundwater in the
study area can be classified as Class 2. And according to CONAMA Resolution No.
357/2005, 100% of the sampled groundwater wells are the sweet type. It is recommended that
some actions in the Campus area UFPA such as: qualitative monitoring water analyzed to
better control, perform preventive and corrective maintenance of treatment units, as well as
the exchange (respecting the validity) and maintenance of filters and equipment, in the case of
troughs, in order to ensure water quality for all users.
