Microbial analysis has long been used as an indicator of water quality. Since the
passing of the Safe Drinking Water Act in 1974, microbial standards have been
strictly set by the Philippine National Standards for Drinking Water 2007 to

ensure that the public health is protected from bacterial pathogens. This study
determined and compared the most probable number (MPN) of heterotrophic
and coliform bacteria from the ice samples collected in Trece Martires City
and Tanza public market. The PNSWD were used as a reference to analyze the
samples. The two ice samples from Trece Martires City and Tanza public

market in Cavite were analysed in DOST Water Testing Laboratory in Trece
Martires City using presumptive, confirmed, and completed tests. There is a
high MPN of heterotrophic, coliform, and fecal coliform from ice collected from
the two sampling sites. The heterotrophic, coliform and fecal coliform bacteria
from the ice collected in the two sampling sites were higher compared to the
PNSWD standard. The bacteriological quality of ice did not meet the criteria
guidelines of PNSWD standards in terms of the heterotrophic and coliform

bacteria most probable counts.
