Hi. I am a retired electrical engineer who suffers from OCD. As you may know OCD is when one lets emotional thinking overcome rational thinking. A few days ago. I checked my car battery fluid and decided it was low, so I added some distilled water.  A few hours later my OCD thinking thought maybe I added too much. I then removed about 2 to 4 oz. Because it was raining hard outside, I dumped the small amount on the outside ground thinking it would be safely diluted. I then made the mistake of looking up spilled battery acid on the internet. From that I learned that the main danger in battery acid is the lead content. My rational thinking tells me the amount of lead in the 3 oz is too small to cause a problem. My OCD emotional thinking tells me that I contaminated the whole neighborhood including my vegetable garden. I now realize I should have just bottled the acid and dropped it off at a proper hazard center. Since this is a chemical forum, any thoughts or comments on this would be appreciated.

The amount is too less. Of course you contaminated somehow your ground, but it will be so low that nobody get harmed.

Solubility of the lead in sulfuric acid is very low, there were only traces present in the liquid. No reasons to worry.

Thanks for the comments. This agrees with my rational thinking.
