Abstract

Even today, many rural and remote communities still do not have access to safe drinking water, which is a basic right of every human. To address this problem, the effectiveness of the Benguet pine tree (Pinus kesiya) xylem as a sustainable water filtration method for well water was investigated. The physical and chemical properties of the filtered and unfiltered deep well water were tested: the total dissolved solids (TDS) and the electrical conductivity using a 5-in-1 electronic water quality tester and the pH level using pH strips. On the other hand, the microbiological metrics, such as heterotrophic plate count (HPC) and the total coliform count, were tested using the Pour Plate Method and the Multiple Tube Fermentation Technique, respectively. The properties of both water samples were compared with each other and with the acceptable values. The results show that the two water samples contain TDS and pH within acceptable levels. Notably, the Benguet pine tree xylem is highly effective at filtering the deep well water and lowering TDS (M=84.7, SD=7.50), electrical conductivity, and HPC (M=325, SD=31.1) within acceptable levels without affecting the pH level, but demonstrated limited effectiveness in removing microorganisms such as coliforms. Furthermore, it can filter 52.9 mL of deep well water every hour. Overall, the results suggest that the Benguet pine tree xylem has the potential to improve the deep well water quality significantly. While these findings highlight the potential of the Benguet pine tree xylem for addressing specific physical water quality parameters, further research is necessary to enhance its overall water treatment capabilities in filtering coliforms and explore its applicability in diverse water quality conditions.

Abstract in Filipino [Abstrak]

Nanatili pa ring suliranin sa maraming rural at liblib na komunidad ang kakulangan sa ligtas na inuming tubig, na isang batayang karapatan ng bawat tao. Bilang tugon dito, sinuri sa pag-aaral na ito ang bisa ng Benguet pine (Pinus kesiya) xylem bilang isang sustainable na paraan ng filtration ng tubig galing sa deep well. Pinag-aralan ang physical at chemical properties ng filtered at unfiltered na tubig, kabilang ang total dissolved solids (TDS) at electrical conductivity gamit ang 5-in-1 electronic water quality tester, at ang pH level gamit ang pH strips. Samantala, ang mga microbiological metric tulad ng heterotrophic plate count (HPC) at total coliform count ay sinuri gamit ang Pour Plate Method at Multiple Tube Fermentation Technique. Pinagkumpara ang properties ng dalawang sample sa isa’t isa batay sa mga pamantayan. Makikita sa mga resulta na ang parehong sample ay nagtataglay ng TDS at pH sa angkop na lebel. Kapansin-pansin na epektibo ang Benguet pine xylem sa filtration ng tubig sa deep well at sa pagpapababa ng TDS (M = 84.7, SD = 7.50), electrical conductivity, at HPC (M = 325, SD = 31.1) sa angkop na lebel nang hindi naaapektuhan ang pH level, ngunit limitado ang kakayahan nito sa pagtanggal ng mga microorganism tulad ng coliforms. Bukod dito, kaya nitong mag-filter ng 52.9 mL ng tubig sa deep well bawat oras. Sa kabuoan, batay sa mga resulta, may potensiyal ang Benguet pine xylem na makapagpabuti ng kalidad ng tubig sa deep well. Bagama’t may potensiyal ito sa physical water quality parameters, kinakailangan pa ng karagdagang pananaliksik upang mapahusay ang kabuoang kakayahan nito sa water treatment, lalo na sa pagtanggal ng coliforms, at upang masuri ang paggamit nito sa iba’t ibang kondisyon ng kalidad ng tubig.
