The pH of the water supply depends greatly on the source, and this can change from day to day, to balance usage of the reservoirs. I have seen pH change from 6.0 to 9.5 in a day. It certainly had to

The topic has become focused on chemical contamination. But what about wasting a precious resource? That is water. Perfectly good drinking water is being used to dye, at a local level. Commercially

Since we built our house 12 years ago, we just put in two lines to the drain in the garage sink, one goes to a small rock lined, with plastic under, pond in the side yard, so the effluent can either

Hi Everyone and Ian I enjoy to weave a great deal and I weave a lot, and as I enjoy to weave there are people that like to dye fiber just as much. I have been a weaver for just under 50 years so lets

Dear Joe, I’m retired from a regional water supplier in New york State after 45 years, so I’m a bit more informed. 1. No level of lead is safe, but there are “allowable”. quantities by law.

Because one never knows the PH of city water which is treated with things to make it safe, it is better not to keep on using the old fashioned lead pipe. Fond du Lac has a similar replacement policy

Hi Everyone If what I am reading is true. That led pipe is safe as long as the calcified lining stays in place. Then why would a city the size of Milwaukee be removing all of the led pipe? It is just

Thank you Ian Bowers, For your educated view and calm good sense. We have so much of "Chicken Little" these days,as regards pollution, COVID-19, and other panics, spread via social media and many

This is becoming somewhat off topic, but since contamination of water supplies is of general interest, I would like to add this. The events that Joe is referring to results from water from a city

As you say, it depends on what you are disposing. The waste from dyeing is low risk, should be well diluted and poured onto unused ground away from livestock. Batteries, computers etc need their own

I have a question about disposing on rough land. Doesn’t it still make its way into the ground water and eventually in our drinking water. Be sure to dispose of old medications at your local

Joe First, lead is a well-known and well understood cumulative poison. Over time it builds up in the body to the point where it is causing damage and can be fatal. Most developed countries

Hi Everyone Michigan changed the chemicals they used in the water treatment plant. In doing so the new chemicals and in the older homes the led pipe had some kind of reaction. I do not remember all

I believe it was in the 80’s in Westchester NY - a guild workshop or it could’ve been at a class held at a MAFA or at a shop like WEBS. I will try to find out more.

I weave in Martha's studio with several other weavers and have done so for many years now. I posted the 4-selvedge video on U-Tube with her consent several years ago. Her bother filmed it and it was

The area of Michigan just north of where I live has a severe and widespread problem with ground and well water contamination from treating shoe leather with waterproofing agents. Children have

Yes I do. Unfortunately Martha now has alzheimers. She lives in Watsonville, Ca, with I believe full time care, by family and beloved guild members. It is a huge loss to our weaving community but she

The video is dated 1992.

The date on the video is 2018. Is that accurate for the filming? Louise in NorCal ------

I was talking to a friend about a class we took with Martha Stanley in the late 80's in NY. I was wondering if anyone has any information on her.
