Abstract

Hospital records showed that gastrointestinal disease was prevalent in Barangay Mayondon, Los Banos, Laguna. Most of the patients were young children aged from one to five years old and infants aged below one year old. Sampling sites in the barangay were identified with the help of the Rural Health Unit personnel. Ten samplings were done from August 1991 to February 1992. The rainfall average, distance of lake water from the reference point indicating lake water level, the number of gastrointestinal disease incidence and bacterial counts of water samples were monitored. Water samples obtained in deep wells near the lake (approximately 2 m) and away from the lake (approximately 2 km) turned positive for the presence of Escherichla coil while the water samples obtained from the faucets in the same areas turned negative for E. coil tests. Highest bacterial counts (214 cells/ml) of the sample obtained from the well near the lake were recorded during the first sampling (August 18. 1991) when the highest rainfall average (504.6 mm) and the shortest distance of the lake water from the reference point indicating highest lake water level were noted. However, the highest number of gastrointestinal disease incidence (27) were recorded during the month of September, 1991. The water samples obtained from the well near the lake had a higher bacterial counts compared to the water samples obtained from the well away from the lake. These results proved that water from well has fecal contamination especially during rainy season. Multiple Linear Regression Analysis showed that the number of gastrointestinal disease incidence, the rainfall average, the distance of lake water from the reference point indicating lake water level, and the bacterial counts of water samples were significantly correlated.
