Lead pipes and processing film/paper

[Kirk Gittings]

I've owned the house I am in since 1978. It was built in the early 40s. From a previous owner I found out that previously he had replaced lead pipes with the galvanized. One of the DIY things I did when I first bought it was replace the galvanized pipes with copper with lead solder many of those (ones that supply drinking water) I have now been replaced too with the new lead free solder. Fairly recently I had the supply line from the street replaced. Because of a huge tree that grew over the supply line (removed for the pipe replacement) it was all twisted and bent. It was lead and was probably the original supply line. So just curious..........I'm not really asking about safety concerns, my wife is a food safety expert and we are pretty well versed in such.......

What affect, if any, might trace amounts of lead have had on film and paper processing?

We have a lead line into our house. We've been told that since only cold water runs through that very little lead goes into the water. In addition, depending on the water in your area, the inside of the pipes get coated with a mineral deposit very quickly. So unless there's something unusual going on, the amount of lead in you water should be extremely small. I doubt that it has any noticeable effect on your film processing.

Our previous house had a lead supply line which were very common in our area—homes built between 1875-1920s. Our town added something to the water that bonded with the lead pipes to prevent any problems.

We need measure the lead level in your house water and mimic it in our house because your films developed in your house are nicer.

Do you have chlorinated water or another disinfectant or nothing?

Chlorinated.

I never noticed anything to be honest except my failing memory

You are getting excellent results with your negs and prints now. Why would you want to change?

[Kirk Gittings]

As I said I'm just curious. For example I didn't know if lead might create a situation that would compromise archival processing. I had never heard of such but someone might know something I don't.
