Sixteen (16) bathing beaches in Manila Bay were monitored for total and fecal coliform count., DO, and pH. (Figure 1) Data derived from the monitoring showed that of the sixteen (16) stations monitored, 4 stations passed the SB criteria for Fecal Coliform of 200mpn/100ml and 5 stations passed the SB Criteria of 1000mpn/100ml for total coliform, Fourteen (14) stations passed the DO criteria and 9 stations passed the pH criteria for Class SB water. Table 1 showed the detailed results of monitoring.



•9 stations baywide (samples collected at surface, mid-depth and bottom) monitored
•A decreasing trend of DO from top to bottom in all stations

•Except for station 7 DO level in the surface conformed the SB criteria of 5mg/L
