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.

COMPARISON BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY

COMPARISON   BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY Find below the pros and cons of Schlumberger Array over Wenner Array and vice versa Are you a young geologist? Click HERE NOW!!! Advantages of using Schlumberger Array over Wenner                 It requires less manpower and time than Wenner soundings.                 It is less sensitive to lateral variations in resistivity. The potential electrodes are moved only occasionally; In a Wenner sounding the potential and the current electrodes are always moved after each measurement. It is faster in field operation. Types of VES Curves Requires less physical movement of electrodes than the normal Wenner array because only the current electrodes must be moved between readings. The effects of near surface, lateral inhomoge...

CAUSES OF WATER BOREHOLE FAILURES IN NIGERIA

HAVE YOU HEARD ABOUT OIL SHALES BEFORE?? Water is one of the most (if not the most) essential requirements for life existence on earth. It is a well known fact that the human body is made up of about 75% water. Apart from water for drinking, it is relied on for industrial and domestic chores. It is available in the surface and sub-surface. But the surface water is usually not enough and in most cases not available all year round due to seasonal variations namely: Rainy and Dry Seasons . During the Rainy Season, the Surface water becomes readily available (though may or may not be enough depending on the need) but the contrast is the case during Dry Season. Hence the resort to Boreholes . Let’s start by defining a Borehole. In the simplest term, as the name implies: Bore Hole.  It means to ‘ bore a hole’ ; or simply put: ‘to drill a hole’, ‘to sink a hole’, ‘to punch a hole’ on the ground to create a cavity inside the ground where water can accumulate, be sto...

Vasquez Rocks

Have you heard of Vasquez Rock? Credit: The above picture will be alien except to those within the vicinity of Aqua Dulce, California or perhaps, those that have visited here at one time or the other. Just watch the arcs and the angles formed by this deposit!! In case you do not know, the image you are seeing is Vasquez Rocks. Am fascinated about the arcs and the acute angles formed by this deposit.. Your groundwater may be polluted!!! Nature is indeed wonderful!!!! For emphasis sake, this is in Aqua Dulce, California, north of Los Angeles. Research has it that the ‘arcs’ formed (i.e. tilting was as a result of the North American Plate collision with the Pacific Plate) along the San Andreas fault. We can see that the collision resulted in the uplift.
