Laboratory test kits are the only way to test your water for PFAS. Whether you’re purchasing them from a provider or receiving one from a public utility or health department, you will be collecting a sample of your water for analysis. ...
While there are more than 12,000 PFAS chemicals, labs are only capable of testing for a tiny fraction of them. And there’s constantly new data emerging about the dangers of PFAS. After reviewing our test results, we asked Birnbaum what she found most troubling. “That they’re every...
. quantified using MacConkey and M-FC media, respectively (HiMedia Labs Pvt. Ltd.). Analyses were conducted by the Wellcome Research Laboratory at CMC. Three dilutions were initially performed for TC (direct, 1:10, and 1:100) and two for FC (direct and 1:10) using a single sample for...
In Brian’s drawing the chimney stands splendidly on the hill like a round tower and its medieval resonance is echoed by the distant castle across the water. My thanks to Mark and Terri O’Mahony for allowing me to use their photographs and drawings in this post, and to Brian Lalor for ...

Porifera, a spin out of Lawrence Livermore National Labs, has come up with a way to skirt the manufacturing problem and devise a product that leverages the unique thinness of single walled nanotubes. It has made a water filter of single walled carbon nanotubes. The tubes are packed closely ...
Assuming that some of the nitrogen in the 398 eV bonding energy state could come from N-protonated amide fragment, the increased amount that was observed for sample JK39 (see the green line in Fig. 2C, for sample JK39, it was 22% of all of the nitrogen, for HexakisaminoC60—13%) ...
If your freezer isn't very cold--say -10C--and you have a sample of water that will supercool to -5C before freezing starts, then the latent heat of fusion will be transferred slowly, proportional to the 5C difference. If you also have another sample of water that is crystallizing at ...
What else may be inside the refrigerator affecting circulation(s)? Etc., etc Let say I infer wrong. May be the two beakers were at the same spot and test one after the other. Again, conditions will be different for the two of them because they were there at different time. Immediately...
