Requires landlords of certain properties providing child care services who refuse lead service line replacements to install and maintain water filters.

This bill requires landlords of properties used for child care services (like daycares caring for 6+ children under 13) to install and maintain NSF/ANSI-certified water filters at all fixtures used for drinking, food, or baby formula if they refuse to allow public water systems to replace lead service lines. Landlords must certify annual filter compliance to the Department of Environmental Protection and face civil penalties of up to $500 per day for violations. The requirement applies until lead lines are replaced and for six months afterward, with tenants able to seek court-ordered rent escrow if landlords fail to act. The bill targets lead exposure risks in child care settings where landlords block infrastructure upgrades.
