How is Water Tested for Contamination

Water become susceptible to contamination due to the diverse avenues it has to go through before being consumed. A contaminant is any substance whether chemical, physical or biological that forms the total volume of water. Research indicates that not all contaminants are harmful to human health.

Let’s look at the various types of contaminants and how they can be identified. In addition, I will talk about the need for getting your water tested for contamination. Types of water contaminants Major water contaminants include: solid, bacterial, gases, biological, metal, chemical, physical and radioactive contaminants, in each one of them I will give one example.


Chemical contaminants include herbicides. Biological contaminants include viral or fungal contaminants which may originate from for instance dead bodies. Gases contamination may include sulphur. Radioactive contaminants may be resulted from chemical contamination as listed above. Physical contamination is categorised in refuse contamination such as plastic materials and cans. Metal contaminants include, lead, iron, mercury zinc, etc. Bacterial on the other hand include sewage contaminants such as coliform.

Ways of testing

There are several ways of testing water contamination that include domestic and commercial options. At the domestic level, one can identify water contaminants by simply filtering the water and researching the residue. To identify bacterial elements that are in water, one can carry out aerobic and sulphate reducing bacteria tests. This test identifies a bigger percentage of elements associated with bacteria in water.

Another common way of identifying contaminants is lab consultation. Almost every town has water authorities who take water samples and carry out tests. Public water supplies are taken to water treatment plants and tested for availability of contaminants.  Here is how to test your water.

Need to test

Water contaminants lead to pollution and consequently results to illnesses. Viruses, bacteria, parasites, chemicals and toxins found in water pose a major threat to the health of the consumer. When consuming untested water, one should be worried about vices such as Salmonella, Staphylococcus, Cryptosporidium, Hepatitis A, Shigella and E. coli.

Water testing whether, domestic or commercial, must be tested basically so as to regulate and safeguard health risks among the consumers. Water authorities should stay updated on the various issues causing water contamination and apply the necessary methods of control and treatment in their water supply plants. Water supply authorities and health departments should create awareness on health risk associated with contaminated water. Many of the risks associated to water contamination are sourced from the major sources of water that include oceans, streams, ponds and lakes among others.

3 Reasons to Get Your Soil Tested

It is important to sample your soil in order to know the component of the soil before planting any crop. Agricultural production largely depends on the contents in term of mineral, acidity and the structure of the soil. There are three types of soils; Loom soil, clay soil and sandy soil. All the three soils can grow a plant, but it will produce different results when it comes to harvesting, this is because soil type influences crop production. You can use a soil testing Kits that are available in agriculture shops or you can involve a soil doctor to test the soil for you in the laboratory.Here are 3 reasons to get your soil tested.

To determine the soil Fertility

Fertility of the soil is the level of the nutrients contained in that soil which determines the yield of the crop. Different crops required different nutrients to grow. Soil testing will determine the type of crop to plant and the nutrients need of that crop in order to know the right type and quantity of fertilizer to use for that crop. This enables the farmer to achieve the maximum yields from that crop.

To determine the PH level of the soil

PH determines the acidity of the soil.The acidity level of the soil means that one of the nutrients is lesser than the other. For example, a soil with 7.8 PH means that the percentage of the phosphorus in that soil is lesser than the soil with 6.8 PH. which requires the farmer to know what nutrient require improvement than the other hence the use of the right fertilizer for a particular crop.

To determine the soil borne diseases

Soil borne diseases can be very frustrating, the farmer can do everything right but get disappointed during harvesting due to these diseases. The only way to know what disease your soil is suffering from is by doing soil testing. The soil Borne disease can affect the entire field to an extent of producing zero yields. It is, therefore, a serious factor to watch in crop production and use the right method to eliminate the disease.

In summary, Soil fertility is determined by the percentage of minerals in the soil. The right composition of the soil should contain the right percentage of Nitrogen, Phosphorus, Potassium, and Magnesium when there is a deficiency of any of the mentioned mineral the crop will not form properly affecting crop yield. The mentioned mineral can be added to the soil by using the right fertilizer and by balancing the level of acidity by applying lime in the soil.
