| Summary: | Earthquakes can cause damage to water and sanitation infrastructure and even
impact public health. The clean water piping system that has been provided by the
Institute for Research and Community Service (LPPM) ITB in the aftermath of the
earthquake disaster in Wangunjaya Village Cianjur Regency, needs to be evaluated
for health risks related to the provision of clean water after the earthquake disaster.
The membrane filter method and observation of environmental infrastructure were
conducted to determine the condition of clean water supply and sanitation. Data
analysis used Spearman correlation and QMRA. The results of water source tests
in areas that received ITB piping assistance did not generally find Total Coliform
and E. coli contamination that exceeds the quality standards of Minister of Health
Regulation No. 2 of 2023. A total of 68% have latrine facilities but do not have a
fecal distribution or treatment system. There was a significant correlation between
the variable well depth (p-value = 0.001) with Total Coliform contamination, a
distance of latrine facilities (p-value=0.009 and 0.049) with E.coli, and Total
Coliform contamination. Quantitative microbial risk assessment showed that there
is an annual infection probability of Pinf, which is higher than the risk level for
E.coli < 10-4
. This study is expected to provide an overview of the condition of water
supply, sanitation, and public health risks related to the bacteriological quality of
water that can affect the success of water supply after the earthquake disaster. |
