“…Furthermore, drinking water in upland and coastal communities in Misamis Oriental, Philippines, was reported to be contaminated with fecal coliform [16]. Lastly, surface waters in Marawi [17] and Dugwells water sources in Zamboanga, Philippines [18,19] were also detected with coliforms.…”

The study aimed to determine the presence of fecal and nonfecal coliforms in selected drinking water sources of Santa Maria, Davao Occidental. Three (3) barangays were purposively identified as sampling sites, namely: Barangay Pongpong, Barangay San Isidro, and Barangay San Roque, where spring water, Jetmatic, and manual water pump are the sources of drinking water. The study was conducted at Sta Maria, Davao Occidental Philippines from August 2021 to December 2021.The water samples were collected aseptically from the identified reservoir in the drinking water of the selected barangay of Sta Maria, Davao Occidental. The collected samples were brought to the SPAMAST Microbiology Laboratory. One (1) mL of sample was plated aseptically in the coliform Petrifilm. The plated water samples were incubated at 35-37 degrees Celcius for 24 hours. Colonies in the Petrifilm were counted manually and recorded as colony-forming units (CFU). Microbial analysis detected the presence of total coliforms on the drinking water reservoir from the spring water source from barangay Pongpong, manual water pump and spring water source from barangay San Isidro and the manual water pump from barangay San Roque. Meanwhile, noOccidental, Philippines. Generally, the drinking water sources of the three (3) barangays exceeded the national standard set by the Department of Environment and Natural Resources (DENR) and the World Health Organization (WHO). Periodic monitoring on the drinking water sources in the identified barangays is highly recommended.

“…The daily NDWQS suggestions were at odds with this. Tonog and Poblete (2015) reported the bacteriological property all sampling are positive for fecal coliforms in drinking water supply in the Phillipines. This implied that all water sources are no longer impervious for drinking.…”

The study objective is to evaluate the current drinking water quality in Baglung Bazar. In this investigation, the physio-chemical characteristics of water samples were assessed using tried-and-true techniques. To gauge the degree of bacterial contamination, the total number of coliforms was measured using a conventional membrane filtering method. Random water samples were taken and examined from a number of locations close to Baglung Bazar. The mean water sample’s temperature was 22.3°C. Maximum and minimum temperatures were reported in S6 (24.7°C) and S10, respectively (18.9°C). In filtered water samples, the pH was found to range from 7.29 to 8.1, which is within the acceptable range at the time of the study. The S7, S3, and S8 taps’ electrical conductivity measurements showed minimum and maximum values of 70 S/Cm and 145 S/Cm, respectively. All of the samples were within the 20 to 35 mg/L range for hardness. The iron readings typically recorded ranged from 0.10 to 0.35 mg/L. The S2, S4 and S8 contained the highest concentrations (0.30 mg/L and 0.35 mg/L, respectively). It was found that none of the samples in the current investigation contained Arsenic. Out of 10 sources examined, six (60%) were Coliform-free, while 40 (40%) were determined to be contaminated with total Coliform. The results of the investigation back up the claim that the drinking water in Baglung Bazar is currently unsatisfactory and unsafe for direct consumption. To prevent the spread of waterborne diseases, drinking water must be frequently tested and cleansed before use.

“…Highest Cd concentration (0.1560 ppm) was recorded in the science center faucet whereas the sample from the IT faucet had the lowest Cd concentration (0.1254 ppm). The high levels of Pb and Cb can be associated to impurity or leaching of zinc galvanized pipes, lead fitting-solder pipes, cadmium-containing solders in fittings, water heaters, water coolers, and taps (Tonog and Poblete, 2015). …”

The study evaluated the quality of drinking water sources in the University of Science and Technology of Southern Philippines (USTP). The main objective was to determine drinking water quality of different water sources in the university. Six sampling stations were identified which included faucets and water fountains in the different departments of the university, namely engineering, science center, education, and information technology. Physicochemical analyses included pH, temperature, dissolved oxygen (DO), total dissolved solids (TDS), alkalinity, lead (Pb), and cadmium (Cd). Sampling periods commenced on July to September 2014. Overall the university's drinking water sources were within allowable limits set by the Philippine National Standard for Drinking Water (PNSDW). However, Pb and Cd concentrations were beyond the permissible limits. Risk assessments for both metals showed potential contamination. The results of the study is preliminary by nature and further monitoring be implemented.
