RESUMO:

The central question of this research was to analyze the physical-chemical data of water quality in the Jauquara

River Basin (BHRJ) for water use in irrigation and for human consumption, verifying that they are within the limits

established by the literature. To this end, methodological strategies were adopted to be applied at 21 BHRJ collection

points using the variables of Hydrogenionic Potential (pH), Electrical Conductivity (EC), Chloride (Cl-),

Calcium (Ca2 +), Magnesium (Mg2 +), Potassium (K +), Sodium (Na +), Hardness (Dur), Bicarbonate (HCO3-),

Phosphorus (P), Nitrogen (N) and Dissolved Oxygen (OD). Some of these variables were used to calculate the water

quality indexes for irrigation, such as: the Kelly Index (IK), the Percentage of Soluble Sodium (PSS), the Hardness

expressed in French Hydrotimetric Degrees (GHF), the Index of Permeability (IP), Magnesium Adsorption Ratio (RAMg)

and Sodium Adsorption Ratio (RAS), and the classifications of these ratios were based on the existing literature. While

the acceptable data for human consumption will be evaluated by Annex XX of Consolidation Ordinance n. 05 from the

Ministry of Health. The statistical techniques used were the average, the maximum and minimum values, normality

test by the Shapiro-Wilk methods and the Chi square test (X2) and multivariate analysis, namely Cluster Analysis

( AA) and Factor Analysis / Principal Component Analysis (AF / ACP). The results referring to the general analysis

of BHRJ, reveal that AA has three predominant groups, and that of ACP three Main Components, in which the

highlighted element were HCO3-, Ca 2+, Mg2 +, Dur and CE both in the dry and in the dry season. in the rain.

In the irrigation analyzes, he observes that the means that had changes were in the variables K +, pH and RAMg,

in addition to presenting low and medium risk of salinity (C1-C2) and low sodicity (S1). Therefore, this research is

partially concluded that contamination of BHRJ is given by a set of environmental factors, whether these activities

are anthropic and / or the dissolution of rock ions in water bodies.
