  • The well-known stories about environmental problems tend to focus on big, recognizable targets such as smoking industrial facilities, leaking toxic waste dumps, and messy oil spills. As a result, people often forget about water pollution caused by smaller nonpoint sources--especially pollution at the household level. Although individual homes might contribute only minor amounts of NPS pollution, the combined effect of an entire neighbourhood can be serious.
  • These include eutrophication, sedimentation, and contamination with unwanted pollutants.
  • Prevent flushing down oily and greasy substances through kitchen basin. It can lead to contamination of ground water and other water bodies too.
  • Prevent flushing down oily and greasy substances through kitchen basin. It can lead to contamination of ground water and other water bodies too.
  • Paved surfaces also transfer heat to runoff, thereby increasing the temperature of receiving waters. Native species of fish and other aquatic life cannot survive in these warmer waters.
  • Paints, used oil, cleaning solvents, polishes, pool chemicals, insecticides, and other hazardous household chemicals. Many of these products contain harmful substances -- such as sodium hypochlorite, petroleum distillates, phenol and cresol, ammonia and formaldehyde and if disposed off into drains, sinks, and toilets can end up in nearby water bodies.

  • We should primarily reduce the use of non-degradable products but non-degradable products such as disposable diapers and plastic bags and other harmful substances like drugs and medicines – should never be flushed down the toilet. They can damage the sewage treatment process and end up littering beaches and waters.
  • Urban and suburban landscapes are covered by paved surfaces like sidewalks, parking lots, roads, and driveways. They prevent water from percolating down into the ground, cause runoff to accumulate, and funnel into storm drains at high speeds. When quickly flowing runoff empties into receiving waters, it can severely erode stream banks.

  • Over-watering lawns can increase the leaching of fertilizers into groundwater which could then contaminate the groundwater or nearby oceans. It is preferable to use slow-watering techniques on lawns and gardens.
  • Grasses and natural ground cover can be attractive and practical substitutes for asphalt driveways, walkways, and keep the natural ground cover intact and allow rainwater to slowly seep into the ground.

  • Planting Non-Native plants that need fertilizer and extra water can increase the potential for higher runoff volumes, increase erosion, and introduce chemicals into the path of runoff By using native plants that are well-suited to a regions climate and pests, we drastically reduce the need for irrigation and chemical applications.
  • It is not only the duty of government and large corporations to work on environmental issues like water pollution. Even kids and every individual can contribute to water pollution.

  • Water Pollution From Households
    • A Presentation By Karan Rajpal
  • Households as a source of water Pollution The combined effect of an entire city or town can be serious.
  • Its Effects
    • Eutrophication, Sedimentation, and Contamination with chemical pollutants.
  • Kitchens and Water Pollution Prevent flushing down oily and greasy substances through kitchen basin
  • Kitchens and Water Pollution Reduce overuse of soaps and detergents. The phosphates in the cleaning agents can aid eutrophication in surface water bodies, if the waste from your home goes untreated to a lake or a stream.
  • Water Pollution from bathrooms 6 Use natural soaps and shampoos as far as possible. Not only are they good for your skin and hair, they reduce the amount of phosphates in the waste water. Try ‘shikakai’ instead of shampoo and ‘besan’ instead of soap.
  • Water Pollution from bathrooms Try to use natural cleaners for sinks and toilets.
    • Excessive organic wastes and phosphates in wastewater can cause eutrophication of lake
    This results in the death of the entire lake ecosystem
  • Proper Chemical Use, Storage, and Disposal
    • Paints, used oil, cleaning solvents, polishes, insecticides, and other hazardous household chemicals.
    Can end up in nearby water bodies.  Reduce, Reduce, Reduce  
  • Proper Chemical Use, Storage, and Disposal
    • Donate medicines that you have no use for but still have a way to go before expiry.
    Reduce, Reduce, Reduce  
  • Segregate your wastes Segregate your wastes. Compost food wastes. Give away every bit of recyclable waste to the kabadiwallah . This includes paper, junk mail and envelopes, pet bottles, glass containers, plastic boxes and lids, plastic covers in which your groceries are packaged, metallic items etc. The kabadiwallah network will ensure that these wastes are recycled, instead of them ending up in a landfill or a drain and contaminating groundwater or blocking storm water flows. When rainwater falls on a municipal solid waste dump, chemicals in the dump mix with the rainwater and this polluted water seeps into groundwater aquifers over time.
  • Recycle and Dispose of Trash Properly  Non-degradable products – Plastic Bags, Disposable Diapers Other Dangerous Waste – Drugs and Medicines
  • Between Households When it rains, clean rainwater gets polluted with all these contaminants. The polluted rainwater flows into lakes and streams and impacts the water quality of these water bodies as well. Paved surfaces like sidewalks, parking lots, roads, and driveways have oil, grease, garbage, dirt and a host of other pollutants. ` `
  • Rainwater Harvesting Harvest as much rainwater as you can from your rooftop, before it gets mixed with contaminants from the street or the storm water drain.
  • Rainwater Harvesting Look for alternatives to cement and concrete for paving the front yard. Use materials that will allow the rainwater to seep through into the ground.
  • In The Garden
    • Avoid over-watering lawns and gardens.
    Use organic manure and herbicides instead of chemical fertilizers and pesticides Increases the leaching of fertilizers into groundwater
    • Grasses and natural ground cover can be attractive and practical substitutes for asphalt driveways, walkways.
    • But pesticides and fertilizers used on these lawns, leach into groundwater and pollute it.
  • In The Garden Non-Native plants need fertilizer and extra water They can increase the potential for higher runoff volumes, increase erosion,and introduce chemicals into the path of runoff Check with the forest department in your town or city for a list of plants native to your region.
  • So let’s get together and Make a Difference
