The Bekasi City Environmental Agency (DLH) collected water samples\nfrom the river flow in the Bojong Rawalumbu area, Rawalumbu District,\nBekasi City, on Monday (18\/05\/2026). This action was taken following\nallegations of waste pollution that caused the river flow along the\nRawalumbu Bridge to turn a deep blue colour.<\/p>\n
Wulan Agustina Triwardani, Head of the Pollution and Environmental\nDamage Control Division at the Bekasi DLH, stated that a team had been\ndeployed to conduct on-site inspections. Based on the examination\nresults, the water\u2019s acidity (pH) was recorded at 7.54, indicating\nneutral conditions. The water temperature was 30 degrees Celsius, with\ndissolved oxygen (DO) levels at 4.5 mg\/L.<\/p>\n
Furthermore, the electrical conductivity (DHL) was recorded at 644.35\n\u00b5S, indicating the presence of dissolved substances in the water, while\nfree chlorine levels were found to be 0.08 mg\/L. Although several\nparameters remain within reasonable limits, the DLH noted that the\nphenomenon of the water turning blue still requires further\ninvestigation to confirm the presence or absence of hazardous waste.<\/p>\n
\u201cFurther examinations are necessary to ensure whether there are\nchemical waste contents or other hazardous materials in the river flow,\u201d\nsaid Wulan. She added that the current condition of the water appears\nturbid, though no sediment or pungent odours were detected.<\/p>\n
Observations at the site showed that the river flow from Bridge 0 to\nBridge 9 in Rawalumbu is no longer deep blue, as seen on Friday\n(15\/05\/2026) and Saturday (16\/05\/2026). The water now appears\ngreyish-black with a fairly strong current.<\/p>\n
Previously, a video showing the deep blue river flow in the Bojong\nRawalumbu area went viral on social media after being uploaded by the\n@bekasiterkini<\/span>\nInstagram account. Local resident Ari (55) suspects that the change in\nwater colour originated from ink or screen-printing paint waste from\nhome industries in the surrounding area.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/bekasi-environmental-agency-samples-deep-blue-water-in-rawalumbu-river-results-released-1780914470", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
