In his view, water quality cannot be meaningfully addressed without examining what happens when water is used. According to Dr. Shahady, water moves through a continuous cycle across urban, suburban, and rural America, which is often overlooked by residents. Dr. Shahady emphasizes that improving water quality begins with everyday sanitation behavior inside the home. Those nutrients can contribute to algal blooms and water degradation before eventually cycling back into drinking water systems downstream. Ultimately, Dr. Shahady argues that responsibility for water quality must be shared across households, communities, and public institutions.
