House lawmakers will consider a range of water sector challenges this week, with hearings on both cybersecurity threats to infrastructure as well as a recent massive sewage spill in the Potomac River.

The House Science, Space and Technology Subcommittee on Environment will convene Thursday to discuss cybersecurity threats facing the nation’s water infrastructure and new research on how to prevent them.

The House Energy and Commerce Subcommittee on Oversight and Investigations is meeting Wednesday to scrutinize the causes of a massive sewage spill in the Potomac River. Experts say the spill highlights the risk of aging, underfunded water infrastructure.
