To find the answer to this question, you can use various methods. One option is to search online for reputable sources that provide information about the Chesapeake Bay and its pollution levels.

An organization like the Chesapeake Bay Program (CBP) would be a reliable source of information. You can navigate to their website, which provides extensive information about the bay and its ecosystem.

To find the answer to your specific question, you can use the search function on the CBP website and enter keywords such as "wastewater discharge" or "pollution levels in Chesapeake Bay." This should bring up relevant articles, reports, or data that can provide you with an estimation of the percentage of wastewater discharge into the bay.

In this case, the estimated percentage of wastewater discharge into the Chesapeake Bay is 20%.
