Sampling For Bacteria at home
Anyone who is on their own water supply in the home invariably has – or should, take samples to be tested for bacteria all the time. Taken for a quarterly basis, this kind of check keeps an eye on the effectiveness of a water treatment system and/or the grade of your water supply.
We are now living in a bacteria world. There’s bacteria for us, in us, and around us. The process you use for sampling your household has a huge effects on the reliability of the results. You might want to sample in such a manner as to exclude outside interferences.
Sample location has become the most important considerations. It is advisable to choose a place that’s clean of dirt and clutter on a regular basis, such as a kitchen tap. This is a better choice than say a basement laundry room tub that probably has a great deal of accumulated dirt, grime and grease.
The species of tap is very important too. The most beneficial tap to take a sample from is but one that has separate hot/cold faucet handles, rrnstead of one hot/cold faucet handle. Aforementioned uses a mixer valve, and older time those mixer valves can leak difficulties into the cold water side, regardless if not asking for hot water. Trouble tanks and heaters usually grow bacteria, so could skew your results.
Make sure you run your water not less than two minutes. You would like to make sure that your water is fresh, water that is clean, and not stagnant water that was sitting in your pipes long.
Before you take your sample, remove your aerator. Aerators can collect sediment that may harbor bacteria. Clogging your gutters sample bottle, turn your water off. Warm the tip of your tap by using a propane torch, just unless you hear a squelching noise if the water is turned back on. This tends to kill any bacteria that is on the surface to your tap from life-style that will skew your result.
Finally, you should definitely inspect your sample bottle. Bottles should because of your lab or health unit pre sealed and sterilized. Give your bottle a squeeze. If air enters or escapes, toss the bottle out and become another one. If you are sampling, accept the cap off carefully. Will not touch the interior of the cap, don’t stuff it down, and be sure that you keep the cap usual manner (downwards), so nothing can fall into it.
When submitting your sample, make use of a small cooler and ice pack. Most laboratories prefer it at refrigerator temperature. It’s to ensure that when there is any bacteria inside sample, get wasted grow when it is in transit, skewing the actual outcome.
Follow these simple measures when taking your bacteria samples, and you can be sure that you have accurate results.
