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.
