Many areas of Africa are affected by water pollution and microbial water-bound contaminants like Cholera . The increased demand on water suppliers has often lead to water that is unfit for human consumption, being inadvertently supplied to your tap. This is often the case in many smaller towns throughout South Africa. Were river water is consumed: upstream contamination, via sewerage and human use ( washing of clothes etc. ) is an important consideration for water quality.

Concerns about personal and family health may lead you to question the safety of the water you are using. Recent publicity about water pollution problems and their effect on water used in the home for drinking, cooking,washing and many other purposes. You may be particularly concerned about the quality of your drinking water if you rely on your borehole or other private water supply. With the availability of modern water treatment equipment and the often aggressive marketing of these devices, you may wonder about the need to install such equipment in your home and what if anything some of these filters do. Agricultural water requirements are often neglected. Suitable water leads to improved livestock production.

Why Test Your Water

There is no such thing in nature as "pure" water. Nearly all water contains contaminants, even in the absence of nearby pollution-causing activities. Many dissolved minerals, organic carbon compounds, and microbes find their way into your drinking water as water comes into contact with air and soil. When pollutant and contaminant levels in drinking water are excessively high, they may affect certain household routines and/or be detrimental to human health.

Obvious problems, such as staining of plumbing fixtures and laundry, as well as many objectionable tastes and odors, may be evidence of excessive levels of contaminants in your water supply. Many of these impurities are naturally present and are considered a nuisance, presenting no hazard to human health. The presence of most harmful contaminants, however, is not always obvious and such contaminated water may not cause health-related symptoms for many years. As a result, the only way that you can ensure that your water supply is safe is to have a periodic laboratory water analysis done on your drinking water.

SMI Analytical offers a comprehensive water analysis service,utilizing GC and GC/SAW as well as ICP/AA equipment.

SMI Analytical can test Drinking Water for the requirements of SABS 241 ( Drinking and Potable Water for Human Consumption ). Long term exposure to contaminated water can lead to serious health risks.

An example of natural water contamination: The mineral Flourspar occurs in many areas and can lead to excessive Fluorine in drinking water taken from borehole's. Chronic Fluoride poisoning is manifested by weakness, weight loss, general ill health, joint stiffness, brittle bones, discoloration of teeth ( during tooth formation ), and anemia.
Pesticide residue and industrial pollution in drinking water is a constant problem.

What to Test For

The list of potential water contaminants is very lengthy and impractical to test for in its entirety. Such water testing would be very expensive and unnecessary. In the event that you could have every potential contaminant tested for, relatively few have established standards, or recommended levels, to allow you to evaluate how serious the contamination may be. Knowing which contaminants are most likely to be a problem and being aware of the warning signs of certain contaminants can make such testing more meaningful and less costly.

Several basic tests not only reveal the severity of specific impurities, but also indicate the likelihood of other contaminants being present. For example, low pH, a measure of the acidity of water, may lead to corrosion of plumbing materials, such as copper and lead, which may dissolve and reach unhealthy levels in drinking water. In addition, high nitrate levels indicate contamination by surface water or seepage which may convey other harmful contaminants, such as pesticides, into household water supplies. For this reason, it is a good idea to conduct routine water testing, as often as annually, for the following:

    Total coliform bacteria
    Total dissolved solids (TDS).
    Organic Carbon Contaminants (Pesticides, Industrial Pollution etc.)

Borehole water tests should be performed during spring or summer, and preferably after a rainy period. When considering the purchase of a new home, at the very least, these tests should be performed on the existing water system. Banks and other lending agencies may require these and/or additional tests before approving a loan.

Water in Agriculture

SMI Analytical has helped many Agricultural Companies and farmers with there water requirements. Drinking water for livestock is just as important for animals as it is to humans .The following industries have been served.

    Chicken Farming
    Crop Farmers

Hydroponic farmers often buy pre-mixed soluble fertilizers, These fertilizers do not take into account the total dissolved solids (TDS) in there mixing water. This leads to incorrect fertilization programs, and peak plant growth is not achieved.

Water molecules Ice Model

Water is almost unique among the more than 15 million known chemical substances in that its solid form is less dense than the liquid. The plot at the right shows how the volume of water varies with the temperature; the large increase (about 9%) on freezing shows why ice floats on water and why pipes burst when they freeze. The expansion between –4° and 0° is due to the formation of larger clusters. Above 4°, thermal expansion sets in as thermal vibrations of the O—H bonds becomes more vigorous, tending to shove the molecules farther apart.
