  • Is It Possible to Test for Methane in Water?
  • What is Methane?Methane is a gas that is both colourless and odourless,meaning it is impossible to distinguish when you comeinto contact with it.Methane is lighter than air, and while it is not considereda toxic substance, there are still precautions that mustbe taken when dealing with it.Methane can be found naturally in several differentsituations.
  • Where Is Methane Found?Some of the places that methane gas may be found,include:• Decomposed plant and animal matter• Landfills• Coal mines• Waste water treatment facilitiesEven though methane isn’t toxic on its own, it can bedangerous, and methane gas testing is an importantdiscipline.
  • Is Methane Dangerous?When methane comes into contact with othersubstances, the ‘harmless’ tag can get thrown out thewindow.Methane is highly flammable, and when introduced toheat, sparks or flames it may ignite. In the air, methaneis explosive when volumes reach 5 to 15 percent.When contained in confined spaces, methane has thepotential to displace oxygen, which in turn makes for adangerous situation.
  • What Are the Risks?If you aren’t careful with methane and don’t respectwhat it can do, some of the risks include:• Asphyxiation - if methane displaces oxygen to thepoint where oxygen levels fall below 10 percent,asphyxiation is a possibility.• Explosion - oil rigs and mining projects haveencountered deadly explosions in the past, when themethane levels have risen too high. Methane gastesting is a must when any type of ignitor is present.
  • Risks cont…• Carbon Monoxide Poisoning - natural gas consists of 97 percent methane, and without proper ventilation it’s possible to suffer carbon monoxide poisoning from your residential heating system.
  • Methane in Well WaterIt is possible to find methane gas in well water, whenthe right circumstances are present. If a well is notproperly cased, methane can migrate into the wellwater. In some cases, the gas might also be presentnaturally.Methane may also be present in an aquifier, existing asa dissolved gas within the water. As the well ispumped, the water level gets lower which lowers thewell pressure, releasing more gas from the water.Methane gas testing in water is important in thesesituations.
  • Testing for Methane in WaterIt is possible to test for methane in water, but it must behandled carefully and by highly trained technicians.Collecting the water sample is of the utmost importancebecause the methane moves into the gas phase quicklyand easily, which will give a false impression of howmuch is actually in the water.If you require methane gas testing from water samples,it’s always best to consult a qualified lab as as first step. Lab results will indicate the percent concentration ofmethane in the water.
  • How to Remove Methane From Well WaterVenting pressure and heating water are two ways to get themethane out. Using a galvanized pressure tank along withan automatic air vent lets the gas escape into the air.However, larger volumes of methane may be too much forjust a vented pressure tank, and a cistern with a vent andspray unit might be necessary. Whatever the situation,respect the gas and get professional advice before youproceed.
