NH arsenic limit in drinking water.


And I forgot to write about HB 261 concerning arsenic limits in drinking water.  It would establish a limit of 5 micrograms per liter for arsenic.  That’s really low.  I asked the advocates for this bill (Sen Feltes and Sen Sherman) where this limit came from.  Who or which organization recommended this VERY low limit. Neither of them knew where this VERY low limit came from. We are talking 5 parts per TRILLION here.  Back when I took chemistry in college it was felt than anything less than 1 part per MILLION (1000 parts per TRILLION) wasn’t going to hurt anybody.  Anyhow this cute little bill was adopted on a voice vote (all ayes, no nays).  Dunno how much it will increase everyone’s costs, first to make a measurement that delicate and second to reduce the arsenic content that much.
