each year• Principle source: lead-based paint• NYS Physicians are required to test• Current emphasis: primary prevention

History of NCDOH CLPPP• 1970’s-CDC grant to identify children with lead

poisoning, 9 positions, assigned to community testing

• 1980’s - funding, 1 employee, case management• Late 1980’s - grant from NYSDOH-case

management and Head Start testing • 1990’s – present - expanded grant from NYSDOH

– expanded case management, education, environmental assessment
