    Of course you could send a sheet/roll out to a good lab to wipe out non-procesing issues on your end.

    Well I do think it is my processing, or something related.

    I am going to look into what I need to filter my water. My darkroom is in a shed out back with a very old water system. A lot of possibility there for yucky stuff in the water. Might even try just some filtered tap water from my Brita in the house first.

    Aaah.... I'd bet that's the problem....I'd install a cartridge type filter in the darkroom. I found a clear housing type at Home depot (so I can see the stuff in our city water) or You might just try letting the water run some to clear the line before applying it to film.

    What I would suggest:
    1. load two sheets of film into a holder in your normal manner
    2. expose one sheet of fresh film to daylight (you won't get more highlights than that)
    3. do not expose one sheet of film at all
    4. ship the holder to a top of the line professional lab in New York (eliminates local water issues)
    5. mark the shipment that these are tests so the lab won't freak out when they see blank sheets
    6. examine the results when you get them back

    For the cost of 2 sheets of film + shipping you will have a fairly good indicator of what is going on.

    A true story:

    Back in the '80s I did a lot of 35mm film photography for an advertising agency that was located in a suburban office park. From time to time I used their in-house darkroom. (BTW, it was NOT light tight but, grasshopper, that is another story.)

    If I put some of the tap water in one of the clear darkroom beakers and let it quietly sit for about an hour, you could see a layer of sediment sitting on the bottom. Yuck! This is what people drank every day at work!!
