How pH, Turbidity and TDS affect the quality of water?

1. pH – Chemical safety and taste

What it is: pH measures how acidic or alkaline water is (scale 0–14).

Why it matters for drinking water:

• Health & safety

  • Very low pH (acidic) water can corrode pipes and leach harmful metals like lead, copper, iron into drinking water.

  • Very high pH (alkaline) water can cause irritation to skin, eyes, and digestive system.

• Taste

  • Low pH → sour or metallic taste

  • High pH → bitter or soapy taste

• Disinfection effectiveness

  • Chlorine and other disinfectants work best within a proper pH range.

Acceptable range for drinking water: pH 6.5 – 8.5 (WHO & most national standards)

2. Turbidity – Microbial risk and appearance

What it is: Turbidity measures how cloudy water is due to suspended particles like clay, silt, organic matter, algae, and microbes.

Why it matters for drinking water:

• Microbial contamination

  • Particles can shield bacteria, viruses, and parasites from disinfection (chlorine/UV).

• Disease risk

  • High turbidity is often linked to waterborne diseases (diarrhea, cholera, typhoid).

• Appearance & acceptability

  • Cloudy water looks dirty → people avoid drinking it even if treated.

• Filter efficiency

  • High turbidity clogs filters and reduces treatment efficiency.

Acceptable level for drinking water: ≤ 5 NTU (preferably <1 NTU for treated water)

3. TDS (Total Dissolved Solids) – Taste and long-term health

What it is: TDS represents dissolved substances such as:

• Salts (calcium, magnesium, sodium)

• Minerals

• Metals

• Organic compounds

Why it matters for drinking water:

• Taste

  • Low TDS → flat or tasteless water

  • High TDS → salty, bitter, or metallic taste

• Health effects

  • Excess sodium can be harmful for people with high blood pressure

  • Certain dissolved metals may be toxic at high levels

• Scaling & corrosion

  • High TDS causes scale buildup in pipes and appliances

  • Very low TDS water can be corrosive

• Indicates pollution

  • High TDS may indicate agricultural runoff, sewage, or industrial waste

TDS classification (approx.):

• <300 ppm → Excellent

• 300–600 ppm → Good

• 600–900 ppm → Fair

• 900–1200 ppm → Poor

• 1200 ppm → Unacceptable
