Risk Category	Score (0-100)	Description
Water Stress Exposure:	${results.scores.waterStress.toFixed(1)}	Risk from regional water scarcity.
Operational Water Risk:	${results.scores.operational.toFixed(1)}	Risk from direct water use in operations.
Supply Chain Water Risk:	${results.scores.supplyChain.toFixed(1)}	Risk from water intensity in upstream supply chain.
Water Quality Impact Risk:	${results.scores.quality.toFixed(1)}	Risk from potential water pollution/discharge.
