Whether or not this is a common source of persistent contrails, I am not sure. However, I do feel relatively safe saying that the source of at least some "chemtrails" is aerial cloud seeding and weather modification. Cloud seeding and weather modification in general have been used for decades for various purposes, and this is no hidden fact. I wouldn't venture to call it a conspiracy theory. It just is what it is. Aerial cloud seeding and weather modification occur through various means, using various chemicals (silver iodide and dry ice are common ingredients). I don't claim to know the long term health or environmental effects of this. I am just throwing it out there as a source of debate.
Here are a few links to companies that specialize in this:

Aerial chemical dispersion is also used for other things from time to time, including insect control. After Hurricane Floyd ravaged eastern NC in 1999, aerial insecticide spraying was conducted using Sumithrin, Malothian, Resmethrin, and Naled. This spraying was conducted over 4 million acres in 35 counties (approximately 1/10th of the total acreage in the state). Again, I don't claim to know what the long term implications are from a health and environmental perspective. However, Phenothrin (same thing as Sumithrin) has been discontinued as an ingredient in flea and tick products for pets due to health concerns for the animals. It is considered a neuropoisin that can damage the kidneys and liver. Malothian and Naled are organophosphates, which are generally considered highly toxic, with Naled apparently being considered the worse of the two. Additionally, studies have shown that Malothian is a common cause of insecticide related illness (Of the 133 reported cases of pesticide-related illness, 95 (71.4%) cases were associated with organophosphates, primarily malathion).

I'm sure aerial spraying is used for other purposes not covered here. These are just the purposes that I know of off the top of my head. Again, I don't claim to know the long term health or environmental effects of any of this. I am just saying that aerial spraying does in fact occur for various reasons. I don't think any of it is being done directly for nefarious purposes, however, there may be evidence that some of this may not be completely safe.
