This study was focused on the determination of the water quality in the Hardy River. The aptitude of the water for recreational uses was assessed according to the current standards. Fifteen sampling sites were established, of which five of these are designated for recreational primary activities. Water samples were collected and analyzed using the concentration of Escherichia coli as bacteriological quality indicator, and determining pH, dissolved oxygen, temperature and electrical conductivity. Results show that only five sites meet the maximum allowable value of of 126 NMP/100 mL, three of them designated as recreational. The concentration of Escherichia coli was observed in a range of 8 to 7100 NMP/100mL. From augustto novemberthe water was polluted in all sites along the river.
