How To Test
HOW TO TEST YOUR WATER
The best time to take a rain sample is in the initial stages of a developing rain storm. A migrating low pressure system is best as apposed to an isolated convective cell such as a thunderstorm. Try to collect the sample from the very beginning of the rain event.
Metals testing is not typically expensive, Basic Lab. in Redding California charges 21 dollars per element.
RAIN AND SNOW
- Any clean glass or plastic container can suffice for the collection of a rain sample, try to gather about 8 ounces of rainwater or melted snow.
- Keep your sampling container AWAY FROM roofs, trees, plants, or any other elements that can drop contaminants into the collection container. Any overhead structure, branches from trees, etc, can causal splashing from the ground which again can contaminate the sample.
- Its best to get samples delivered or mailed to the lab of choice soon after the sample is taken. If the sample sits for extended lengths of time, the contaminants can settle out and adhere to the inside of the collection container in a film, this will skew your test results. Particulates must be suspended in the rain sample just prior to testing. If the sample has been stationary for any significant length of time, the inside of the container should be swabbed with a sterile instrument to make sure there is not “film” from the settled out contaminants.
- There are labs around the country that test water. Ask the lab what their “minimum detection levels” are. Many labs have radically raised their detection levels and this now also skews the tests.
- The best primary elements to test for are aluminum and barium. If you wish to do further testing you can include barium and strontium.
- Get the results, hang onto the original and send us a copy, email etc….firstname.lastname@example.org.
Again: When transferring from one container to another, IT IS CRITICAL TO RE-SUSPEND the sample…shake the jar with the lid on, or stir with a sterilized instrument. Aternatively, you can ‘back and forth’ the samples, allowing a little “fall” to create enough turbulence to re-suspend any contaminents that may be stuck to the glass.
