Parameters tested

• pH4.2Std 6–9Acidity of the water. Central Kalimantan peat rivers are naturally acidic (pH 4–6).ⓘ Peat rivers are naturally acidic (pH 4–6). pH below the standard here is usually not a pollution signal.
• BOD (mg/L)2Std 3Biochemical Oxygen Demand — oxygen bacteria use breaking down organic matter. High = heavy organic waste load.
• COD (mg/L)41Std 25Chemical Oxygen Demand — oxygen needed to break down pollutants. High = industrial or wastewater contamination.
• TSS (mg/L)9Std 50Total suspended solids. High = turbid water, usually from sediment, mining, or spills.
• DO (mg/L)3Std min 4Dissolved oxygen. Higher is healthier for fish. Low = oxygen-starved water.
• Fecal coliform (MPN/100mL)40Std 1000Fecal bacteria. High = human/animal waste contamination — diarrhea risk if swallowed.
• Nitrate (mg/L)1Std 10Nitrate (NO₃-N). Often from fertilizer runoff or domestic waste.
• Total phosphate (mg/L)0.04Std 0.2Total phosphorus. High values trigger algal blooms (eutrophication).
• TDS (mg/L)43Std 1000Total dissolved solids — salts & minerals. High = brackish or wastewater-contaminated.
• Water temp (°C)28.5Surface water temperature. Affects oxygen solubility.
• Flow (m³/s)3,483.48Volume per second. Context for scaling pollutant load.
