Lead in Drinking / Groundwater



Possible sources of lead in groundwater
Places well known for lead-zinc (Pb-zn) deposits are in danger of having their groundwater contaminated with Lead.
Lead is a known silent killer especially in infants and children as it has high affinity for Hemoglobin. Another reason it is a silent killer is because it accumulates (bioaccumulation) in the body gradually stealthily.
The fatality of lead is that it gets stored in the bones (as Calcium is stored) and becomes part of the body. From there, it gets released directly into the body. Pregnant and nursing women are the most hit because the Calcium which their bodies require for the growth of the fetus and for breast milk production may be mixed with Lead.
The detrimental effects of lead are enormous and felt among infants / children, pregnant women and adults.
Among the children, these (but not limited to the following) are pronounced:
Ø  Anemia
Ø  Slowed / stunted growth
Ø  Poor body development
Ø  Poor in learning
Ø  Nervous disorders
Ø  Death
Among Pregnant Women, these (but not limited to the following) are pronounced:
Ø  Stillbirth
Ø  Underdevelopment of the fetus

Among adults (men and women), these (but not limited to the following) are pronounced:
Ø  Kidney problems
Ø  Increased blood pressure
Ø  May result to death

Sources of Lead in Groundwater:
·         From mines
·         Buried Lead wastes
·         Intrusions from Lead-zinc ores

Sources of Lead in Public Drinking Water:
o   Lead service pipes
The pH and temperature of your water play a key role as it determines to a great extent how it reacts with the reticulation system.
You can bath with water containing lead because it is not absorsed by the skin. Be that as as it may, care should be taken when bathing children with this water because they are known to be swallowing bath water in the process of bathing.
What to do?
o   Get your groundwater tested for Lead before you start drinking it after drilling
o   Get a good water treatment plant.

THE AGE OF THE EARTH - THE OLDEST MAN ON EARTH IS THE EARTH

THE AGE OF THE EARTH Hey … Just as we celebrate our birthdays to commemorate the day we were born, has it ever occurred to you to ponder on the age of the earth? Don’t you think that there was a day (way back) when the earth was formed? Don’t get it twisted!!! This is no myth. It is a reality. It is REAL!!! The Earth is approximately 4.6 billion years old!!! Sounds absurd??? Well, this figure did not come as a result of fiction or imagination – but by radiometric dating in the early 20 th century. Lead in uranium-rich minerals when dated by early scientists,  were able to discover that they were billions of years old. Another pointer to this is that small crystals of Zircon obtained from Jack Hills, Western Australia when dated, was around 4.4 billion years old. One may ask: “How is this possible”? Rocks are aggregate of minerals. Some of these minerals have radioactive elements like Uranium and Thorium. In the process of their decay (radioac...

Principles and limitations geophysical method of exploration

Geophysics simply means the application of principles of physics in the study of the earth. The application of geophysics is vast. It can be used to study the entire Earth (Global geophysics), or for localized survey of the crust e.g for Engineering purposes. Geophysical survey is broadly classified into two based on the source of energy. 1.        Natural field: This uses the electric, magnetic,  electromagnetic and gravitational fields of the Earth 2.        Artificial source: Involves the generation of artificial electrical or electromagnetic fields into the earth by a means of a D.C. Magnetic method is applied when searching for buried magnetite ores because of their high magnetic susceptibility. Electrical method is used when exploring for ground water because rocks resistances differ according to their water saturation levels. Seismic method is used for hydrocarbon exploration. It is worth noti...
