A year or two ago they had to change the chemicals in pressure treated wood due to environmental concerns.[/b]
Yes, that's right... I wonder if it will also take 40 years for them to realize the new stuff has also been poisoning rivers & lakes and water supplies too.
Hopefully the new green stuff doesn't persist and breaks down harmlessly.
It's due time for everyone to evolve from the 50's to 60's kind of thinking & ignorance about persistant toxic chemicals.

The copper-based green stuff isn't a pesticide or insecticide, it's a 'bacteriacide'. Bacteria is what rots the wood and breaks it down, not insects.
Either way... If anyone reading this lives in the country and enjoys drinking their well water, please be careful about what you end up drinking.
Anything you spray on your lawn, fluids that leak from vehicles, preservatives in wood, etc... If any of these can't biologically break down into harmless states, they end up in the water table. They end up in your well too.
Used motor oil is a known carcinogen. Many additives in new motor oil are carcinogens as well.
If you drink your well water you will get regular small doses of these pesticides, bacteria-inhibitors, motor oil/automotive fluids, etc. Even the stain on your siding or decks can end up in your drinking water.
People wonder why cancer runs rampant these days. Many who drink their own well water never make the connection to things they're releasing into the the water table feeding their well. Just because the human eye can't see it, doesn't mean it isn't happening.
Sorry for getting off topic folks, AB's comment about the motor oil made me think of the connection to drinking water from well sources, as that's what my water supply is. But it's really not a good idea to release toxic substances into the environment anyway, even if you have a municipal water supply.
