Water Supply Testing
Water Supply Testing
Pollution is a real concern in many locations worldwide so the need for water supply testing has intensified as part of government efforts to keep public water supplies clean. When one remembers that today, every facet of human life is exposed to some sort of pollutant, paying more attention to the quality of water that flows through our faucets is a very critical mandate that requires the utmost of efforts by everyone involved.
In the case of water supply testing, there are essentially two proven methods of doing this. The first lies with government-owned laboratories that sample water from various sources and gives their verdict as to the compliance of that water to government standards. The second lies with independent laboratories typically commissioned by corporations to test their effluent water before it is dumped into the sewers or sent to open bodies of water for disposal. A third but largely unexplored area has to do with D-I-Y water supply testing kits sold in retail stores and over the internet which can give a comprehensively assess of the water quality going into a household.
Of course, at the crux of the continuing challenge for water supply testing is the wide expanse of variables and indicators that need to be monitored and tested. These include:
TDS or Total Dissolved Solids. This refers to particulate contaminants that may be present in the water. TDS testing applies to both incoming and outgoing water streams and is important because it measures how much foreign particulate are suspended in the water and whether or not these comply with public health standards for potable or effluent water streams. It bears repeating that potable and effluent water has their own respective standards when it comes to acceptable TDS levels.
Biologically Dissolved Oxygen or BDO. This only applies to effluent water and is a critical indicator for water dumped into open bodies. For example, there are companies that employ their own water treatment facilities to treat industrial waste water before dumping it into a river or lake. BDO ensures that the water has sufficient oxygen levels so it does not suffocate marine life when it is mixed with the water in these open bodies.
Specialized water supply testing. This can cover a wide range of substances depending on the regulations in place. Lead and chlorine are typical elements that are being tested but there are many others that can pose health hazards and must be regularly monitored so it does not enter the potable water supply. Bacterial or microbial presence is also important as there are a lot of ailments that can be transmitted through water. A few life-threatening ones include diarrhea, dysentery, cholera and typhoid fever.
Water supply testing ensures that we remain safe from the effects of polluted or contaminated water. Government regulations ensure that this is an area that is given proper attention, else it can be a serious public hazard whenever the level of pollution in potable or effluent water streams exceed those mandated in public health codes.
