Lake Ontario has a volume of $3\mathrm{.}0$x$10^65$ cm$^3.$ Toronto hospitals have poor water quality processing. The effluent water coming from the hospitals is mainly uric acid $($ka$=2\mathrm{.}7$x$10^-3)$ The average human urinates $1\mathrm{.}27$ L$/$day with a $[]$ uric acid $0\mathrm{.}13$mM$.$ All Toronto hospitals have $12,312$ patients on average. Additionally, Premier Doug Ford has approved mining effluent water into Lake Ontario. The mining process has Fe$($OH$)2$ as a solid being thrown into the lake as a part of this policy. Lake Ontario's indigenous animals and plants need a pH of $7\mathrm{.}4$ to thrive. If the mines release $1\mathrm{.}0$x$10^-8$ kg of Fe$($OH$)2/$ week, and you need to counterbalance the addition of Fe$($OH$)2$ and uric acid thrown into the lake over the course of one year, how much H$3$O$+$ or OH$-$ would you need to add to bring it back to pH $7\mathrm{.}4?$
