Monitoring of Bathing Beaches

Bathing-Beaches

 

To determine pathogens contamination of bathing beaches in Manila Bay, nineteen (19) stations were monitored for total and fecal coliform count, (Figure 1). Data derived from the monthly monitoring from 2011 to 2015 for fecal and total coliform are shown in Table 1 and 2 respectively. In summary, Table 3 showed the number of stations that passed the fecal coliform criteria of 200 mpn/100 ml and 1000 mpn/ml for total coliform from 2011 to 2015.

High levels of pathogens may result from on-site sanitation systems (septic tanks, pit latrines) or inadequately treated sewage discharges. In some areas, combined sewers also discharge untreated sewage during rain storms. Pathogen contamination may also be caused by poorly managed livestock operations. Coliform bacteria, which are not an actual case of disease, are commonly used as a bacterial indicator of water pollution.
