Potential Pollution Sources

Organic Pollution

Organic Pollution

Safe LimitsBOD ≤ 3.00 mg/L
Highest ObservedBOD: — mg/L
Observed At

High organic load from untreated sewage. Promotes microbial growth, reduces dissolved oxygen.

Pathogen Risk

Pathogen Risk

Safe LimitsFaecal Coliform ≤ 500 MPN
Highest ObservedFaecal Coliform: — MPN
Observed At

High faecal contamination from untreated sewage poses serious health hazards.

Chemical Pollution

Chemical Pollution

Safe LimitsCOD ≤ 30 | TSS ≤ 100
Highest ObservedCOD: — | TSS: —
Observed At

Chemical residues, fertilizers, oils alter water chemistry and harm aquatic life.

Turbidity

Turbidity

Safe LimitsSafe Limit: ≤ 25 NTU
Highest ObservedTurbidity: — NTU
Observed At

Suspended solids reduce light penetration and disrupt photosynthesis.

Salinity
