# Plain Language Summary: Public Water Supply Invasive Species Compliance Act of 2021

This bill requires public water systems across the country to take action against invasive species that can damage water infrastructure and contaminate drinking water supplies. Invasive species like zebra mussels and certain types of algae can clog pipes, foul water treatment equipment, and make water unsafe or expensive to treat. The law essentially tells water utilities they need to develop and follow plans to prevent these organisms from getting into their systems and to manage any infestations if they occur.

The bill affects anyone who gets water from a public water system, which includes most Americans who don't have private wells. Water companies will need to spend money on prevention measures like screening intake pipes, treating water to kill invasive organisms, and monitoring for problems. These costs might eventually show up in water bills, though the exact impact depends on how serious the invasive species problem is in each region. Areas near the Great Lakes or other bodies of water with known invasive species problems will likely feel this impact more than others.

The practical effect is that water utilities will have to be more proactive about protecting their systems from biological threats. Instead of waiting for a major problem to develop, they'll need to implement prevention strategies upfront. This is similar to how water companies already test for bacteria and chemicals—this law just adds invasive species to the list of things they need to monitor and manage. For most people, this means their water should remain safer and more reliable, though they may see modest increases in water costs to cover these new protective measures.

Specifically, the prohibitions do not apply to covered water transfers containing prohibited species if <ul> <li>the species are present in both public water supplies before the transfer, the water is subject to effective mitigation measures, and the water is transferred directly between the supplies; or</li> <li>the water is transferred in a closed conveyance system, such as a pipe system, and sent directly to treatment facilities where the species will be destroyed.</li> </ul> The costs of the mitigation measures must be borne by the entity that sells the water for financial gain.
