The Content of Coli Bacteria In Shallow Well Water In Surabaya Small Type Housing Is Very High. Why?

Abstract

—This research is motivated by the fact that the quality of groundwater in small type housing in Surabaya is low, with a high content of E-Coli bacteria. By this fact, it is necessary to study what factors are causing the high content of E-Coli bacteria. Continuing the previous research as a target of the study, this study was conducted in Pondok Benowo Indah Housing (PBI) Pakal subdistrict West Surabaya. From the PIB housing area, four houses/ shallow wells were selected as the center of the study site. This study analyzed several variables such as water quality with several parameters, the distance between septictank and the wells, soil density, soil permeability, many quality of septictank construction of surrounding community activities, channels situation, and frequency of flood. Data were collected by means of measurements in the field, laboratory tests, news on social media, and interviews with local communities. Data processing was done descriptively. This study found that the main factor of the high content of e-Coli bacteria originated from the quality of septictank, there may be damaged, broken, leaking, and the wall is permeabel, so that by the times, it become absorbed and by the soil and run into the well.
