		<ns0:BillSection id="id_4CD5AF8B-8B4F-4B70-8156-F89E5892E7B8">
			<ns0:Num>SECTION 1.</ns0:Num>
			<ns0:Content>
				<html:p>The Legislature finds and declares all of the following:</html:p>
				<html:p>
					(a)
					<html:span class="EnSpace"/>
					Wastewater surveillance is a proven and cost-effective tool for public health monitoring, allowing for the early detection of infectious diseases, including COVID-19, influenza, mpox, norovirus, and antimicrobial-resistant pathogens.
				</html:p>
				<html:p>
					(b)
					<html:span class="EnSpace"/>
					Wastewater monitoring played a crucial role during the COVID-19 pandemic, providing early warnings of infection trends, guiding public health responses, and reducing the burden on
				hospitals and testing systems. 
				</html:p>
				<html:p>
					(c)
					<html:span class="EnSpace"/>
					The State Department of Public Health has demonstrated leadership in disease monitoring and response by establishing a wastewater-based epidemiology program in partnership with the Centers for Disease Control and Prevention, the National Wastewater Surveillance System, academic institutions, local health departments, and wastewater treatment agencies. This program is critical for ongoing disease tracking and the infrastructure must remain in place and at the ready in anticipation of future outbreaks of infectious diseases. 
				</html:p>
				<html:p>
					(d)
					<html:span class="EnSpace"/>
					Despite its effectiveness, wastewater surveillance infrastructure remains inconsistent across California, with significant gaps in rural, underserved, and high-risk areas, including counties reliant on
				septic systems, tribal lands, and regions with vulnerable populations. 
				</html:p>
				<html:p>
					(e)
					<html:span class="EnSpace"/>
					California’s agricultural economy and food supply chain depend on proactive disease monitoring, particularly in the face of outbreaks, including avian influenza, which has already infected over two-thirds of California’s dairy herds and 90 percent of commercial and backyard poultry flocks.
