The New York State Department of Health (NYSDOH) conducted a cancer incidence study that examined cancer registry data from 1976 through 1984 for the Village of Middleport. The study concluded that the cancer incidence for 17-19 different organs or for all cancers combined in men, women, or children was similar to the expected incidence for areas of similar population density for 1978-1982 in New York.

NYSDOH also conducted a biomonitoring study in May and June of 1987 with students from Royalton-Hartland school to evaluate whether students had increased arsenic exposure from the arsenic soil levels detected on school property. Samples were also collected from students from the Albany area (East Greenbush Central School District) as a control group.

No significant differences were found between the Middleport students and those from East Greenbush; however, only total arsenic levels were measured in urine, which can be confounded by dietary organic arsenic sources. None of the total arsenic levels in urine for Middleport students exceeded 50 μg/L; whereas, five students from East Greenbush had levels exceeding 50 μg/L and were retested. Questionnaires from these five students indicated recent ingestion of seafood. Results of Biological Monitoring Program for Arsenic and Lead: Middleport Elementary and Roy-Hart Jr/Sr High Schools (1987)
