Considering the bug spray, I was suggesting a common bug spray product for mosquitoes and ticks. Additionally, perhaps "Clorox" could also include chemical products/services to rid residential/commercial lawns of ticks as well, for Lyme disease is a great concern and due to the mild winter season experienced in some parts of the country this past year the tick population is growing and becoming more threatening to humans’ health. To address your second question concerning dumping bleach into public water systems would not only seem extremely irresponsible, but also at the same time not seem too far-fetched either. Bleach, being a common household object, aids itself to the laundry machine, kitchen floors and countertops, and various other uses that eventually lead to the bleach washing down into septic systems and by any various means of transportation, such as leaching, finds its way to a water source as well.
