Even though we are facing the COVID-19 pandemic, we must not ignore other health problems. Therefore, we will implement a PKM program to check the quality of drinking water for residents in the Sukasari, Pulosari, Pandeglang, Banten Village areas. "We do not yet have the courage to invite residents, even for medical purposes." In connection with this, we need to convey that our PKM officers will only have 2 people to take drinking water samples from sources in RW 04 and 05 (± 20 houses). We will check the quality of the drinking water, and the results can provide input for the health of the population. Drinking water quality checks include levels of Cl, Mn, nitrate, detergent, dissolved solids, pH, organoleptics and coliform bacteria.
