Vermont finds PFAS in 95% of waste samples, as states increase landfill scrutiny | Waste Dive

  • Testing from the Vermont Department of Environmental Conservation (DEC) released recently showed per- and polyfluoroalkyl​ substances (PFAS)​ were in 95% of waste samples from throughout the state. This included the Coventry landfill, owned and operated by Casella Waste Systems, where the toxic "forever chemicals" were found in all samples.
  • Despite the evident contamination, the DEC found "that a small fraction of the PFAS entering the landfill in wastes leave it in leachate." But VTDigger reported high readings for PFAS have been found at two local wastewater treatment plants. One, in Montpelier, took significant levels of leachate from Coventry. The other in Newport no longer accepts the landfill's leachate, but did during the period measured by DEC. 
  • Kasey Kathan, an analyst with DEC, told Waste Dive some of Vermont's PFAS monitoring reports have been completed "in collaboration with Casella" and the state is working with the company on the issue.

Inductive chargers work on the same principle that switch-mode power supplies work in your tiny cellphone wall charger works -- it's just a transformer with two loops of wire -- and while each cycle might not move a lot of current and magnetic fields are very weak -- if you cycle fast enough you can move a significant amount of current with relatively small losses.

Northview Diary: Know Before you Go…..Solar

With the wild proliferation of solar arrays across valuable farm land, scrub land, and pretty near everywhere else, and with solar companies approaching and pressuring farmers to lease or sell, it is important to know the potential ramifications of signing a deal.

Below is an excellent article, which brings up some issues I hadn't previously considered. We have been approached by at least seven or eight companies, so there has been a lot of research done by Northview folks. The solar company reps who call, write, or stop by in pickup trucks don't seem to like that very much.
