Commercial water boring is a smart investment for any commercial property because it ensures reliable water supply without attracting monthly water bills. But if the water in a commercial bore gets contaminated, it may not be suitable for the intended use. There are many potential causes of bore water contamination; some are natural processes, others occur as a result of human activities. While there's nothing that water bore owners can do to prevent chemicals, minerals, bacteria and viruses in aquifers from contaminating the groundwater, they can definitely do something to control contamination that occurs due to human activities.
The following points will explain some human activities that lead to contamination of water in commercial bores and what can be done to manage each one of them.
Excessive use of chemicals
The widespread application of chemical products, such as fertilisers, weedicides, pesticides, and insecticides at the land surface is one of the most common causes of bore water contamination. When these chemicals are used excessively, they can filter through the soil and end up at the aquifers. It is, therefore, imperative for businesses to avoid using such chemicals or to only use appropriate quantities when need arises.
Accidental chemical spills
Another cause of bore water contamination is accidental spillage of chemicals into the ground. When chemicals leak from a point source, diffuse through the soil and reach a shallow water table, the contaminated water can follow the path of groundwater flow and also contaminate aquifers located deep below the ground. This kind of groundwater contamination is typically more severe than that caused by excessive application of chemicals onto the soil.
Accidental chemical spills can be minimised by ensuring that any machine or storage tanks containing chemicals are leak-proofed. What's more, there should be controls to ensure leaks are identified as soon as possible. This will help reduce the severity of chemical spills from leak sources.
Poor waste disposal systems
If hazardous waste generated on a commercial property is not properly removed or disposed of, it has the potential to reach underground water. This is common in septic waste management systems whereby inappropriately maintained septic tanks, poor leach field filtration, and leaky sewage drains can allow bacteria and other pathogens to reach the groundwater.
The best way to prevent this form of groundwater contamination is to make sure that waste disposal systems on the property are regularly inspected and properly maintained.
Commercial bores that are used in a responsible manner are good for the environment, so make sure you take steps to avoid human activities that may contaminate the water in your private bore.
