Analysis Request – Borehole Water
Boreholes are created by drilling holes into the ground to get to the bedrock where underground water may be found and bought to the surface. This water is generally rich in minerals and dependent on the area in which you are going to drill, these underground streams may be flowing abundantly providing you with a lifetime of “free” natural water. This borehole water may, however, contain varying levels of chemical and microbiological contaminants. At Vinlab H2O borehole water is conducted as per client requirements as this water may serve several purposes, be it for drinking water, irrigation water, construction projects or filling of your swimming pool.
The list of both potential chemical and microbiological contaminants in water is lengthily and often impractical. Knowing the purpose of your borehole water will narrow this testing down. If the intended use is as drinking water microbiological indicator organisms, as well as, the critical chemical parameters of pH, total dissolved solids, nitrates, sulphates, iron and manganese should be tested. If the intended use will be for irrigation the critical chemical analyses shifts to Electrical conductivity, sodium absorption ratio and Boron, while microbiological parameters would include Faecal coliforms and E. coli.
Testing the quality of your borehole water is an important part of maintaining a safe and reliable water source. It enables the identification of existing problems, ensures the water is suitable for its intended use, enables you as the borehole owner to track any water quality changes over time and is vital in determining the effectiveness of your treatment system.
Various water quality tests should be performed on boreholes at least once a year. However, if your water supply is contaminated more frequent water testing should take place until well after the problem is addressed.
Although testing can take place all year round, borehole water testing should preferably be performed after a rainy period – particularly if it is to be used as a drinking water source.
The responsibility of delivering microbiologically and chemically safe water falls on any homeowner, farmer or organisation making use of borehole water.
