Change in water quality due to Automotive Lubricants penetration

[Hidam Tonsana]

Water quality is the physical, chemical and biological characteristics of water. The most common standards used to assess water quality relate to drinking water, safety of human contact and for the health of ecosystems. The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for human consumption or in the environment.

Environmental water quality, also called ambient water quality, relates to water bodies such as lakes, rivers, and oceans. Water quality standards vary significantly due to different environmental conditions, ecosystems, and intended human uses.

Some people use water purification technology to remove contaminants from the municipal water supply they get in their homes, or from local pumps or bodies of water. For people who get water from a local stream, lake, or aquifer (well), their drinking water is not filtered by the local government.

A lubricant (sometimes referred to as "lube") is a substance (often a liquid) introduced between two moving surfaces to reduce the friction between them, improving efficiency and reducing wear. They may also have the function of dissolving or transporting foreign particles and of distributing heat.
One of the single largest applications for lubricants, in the form of motor oil, is to protect the internal combustion engines in motor vehicles and powered equipment.

A Motor Servicing Centre performs lots of activity which includes all kind of Cleaning, Mechanical, Electrical Work & Denting / Painting. Taking care of Private / Passenger Cars involves heavy utilisation of water resources and the washed away water becomes the source of contaminants in local water bodies. AC servicing and other servicing is also the source of contaminants. Car Wash may be Interior or Exterior Cleaning.
• Small Car = Maruti 800, Esteem, Indica, Indigo, Ikon, HondaCity Etc.
• Big Car = Tavera, Qualis, Innova, Scorpio, Sumo, Bolero Etc.
Every Motor Company has their own Servicing Centre and the effective utilisation of water resources differs from company to company. The effluent of the washed water is either disposed to local water bodies or goes underground.
The complexity of water quality as a subject is reflected in the many types of measurements of water quality indicators. The following is a list of indicators measured for the study:
Chemical assessment
• Conductivity
• Dissolved Oxygen (DO)
• Chemical oxygen demand (COD)
• Biochemical oxygen demand (BOD)
• Dissolved metals and metalloids (lead, mercury, arsenic, etc.)
• Dissolved metals and salts (sodium, chloride, potassium, calcium, manganese, magnesium)
Physical assessment
• pH
• Temperature
• Total suspended solids (TSS)
• Total dissolved solids (TDS)
• Turbidity
• Colour of water.

[Mohammad Jawaid]

people required to think about pollution they are creating indirectly.

[pankaj panwar]

yes it is a great problem and one of the major causes of the water pollution.we have to take step against this.

[Unnikrishnan]

Yes this is a matter that has to be taken up. All the servicing stations need to have a treatment plant which consists of a sedimentation tank and a tank for removing the floatable namely Oil and grease, but in reality these plants is not working or is neglected due to the lack of knowledge by the owners of the servicing station. This matter has to be taken up and the Srevicing station owners should be educated regarding this.
