EVALUATION OF THE MICROBIAL CONTAMINATION OCCURRENCE IN THE AQUIFER UNDER VÁRZEA CEMETERY IN RECIFE CITY, BRAZIL
Abstract
Occurrence of microorganisms in the aquifer under Várzea Cemetery located in Recife city (Brazil) was evaluated. From January to August of 2003, samples from well waters of eight wells of residences surrounding the cemetery and three wells of the cemetery field were analyzed. Analysis were divided in five sets. Most Probable Number of coliform bacteria, thermotolerant bacteria, Pseudomonas aeruginosa, Clostridium perfringens and proteolytic bacteria were estimated by using the multiple tubes technique. Heterotrophyc bacteria were counted by using pour-plate technique. It was observed decreasing of coliform populations in presence of Pseudomonas aeruginosa. The results indicated microbial contamination of the aquifer by the leachate.
