Commercial properties face significant liability exposure from heavy metals contamination that affects employees, tenants, or visitors. Property managers need professional testing to identify contamination sources and demonstrate due diligence for insurance and regulatory compliance. Older buildings with lead plumbing, properties near industrial sites, or facilities using well water require regular monitoring to protect occupants and avoid workers’ compensation claims. Environmental contamination can impact property values, insurance coverage, and sale transactions. Professional testing provides essential documentation for liability protection and helps identify remediation needs before contamination causes health problems or regulatory violations.
