Water Pollution

Water pollution is the contamination of water bodies like lakes, rivers, oceans, aquifers and groundwater. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.

Main Causes

  • Disposal of untreated municipal liquid waste
  • Leaking sewer lines
  • Industrial waste water

Effects

  • Drinking water contamination
  • Pollution of Water Bodies i.e River Ravi, Hudiara drain, Lahore Branch Canal
  • Sub-soil water pollution
  • Loss of aquatic life
  • Crop damages
  • Heavy metals in food chain
  • Increased rate of water borne diseases

Remedies

  • Treatment plants for municipal and & industrial effluents before disposal to water bodies
  • Adequate collection, recycling and disposal
  • Application of “Clean Technology” at the industrial units
  • Segregate sewage lines to avoid mixing with drinking water supply
  • Fitter plants for clean drinking water
  • Application of 3R formulas i.e. Reduce, Reuse, and Recycle 

How to conserve water

  • Don’t pour water down the drain. Instead, use it to water your plants or garden
  • Fix dripping faucets, one drop per second wastes 2700 gallons of water per year
  • Take shorter showers and turn off the water while you lather up
  • Turn off the water while brushing your teeth or washing your face
  • When hand-washing dishes, use two containers-one with soapy water for washing and the other with plain water for rinsing
  • Don’t water your lawn too much. Grass only needs to be watered about once a week in the summer. Lawns can go two weeks without water after a heavy rain
