The comprehensive study, which analysed water quality across 11 major rivers in Odisha, found high levels of biochemical oxygen demand (BOD), dissolved oxygen (DO), total coliform (TC), faecal ...

However, effluent samples were taken from both the discharge end of the farm and the discharge pipe in the river area, and these samples have been sent for testing of Biochemical Oxygen Demand (BOD). ...

Most of these samples contained dead bacteria so the fifth-graders viewed little to no movement. Blockler said he routinely conducts biochemical oxygen demand and chemical oxygen demand tests on the ...

The treated water must meet BOD (Biochemical Oxygen Demand) standards of under 20 milligrams per liter. The clean water will be repurposed for non-potable uses such as watering plants and cleaning ...

However, levels of chemical oxygen demand (COD) and ammonia found to be at high level, which exceeded acceptable limits for navigable water. The Cebu City Environment and Natural Resources Office ...
