Changes in Exposure to Arsenic Following the Installation of an Arsenic Removal Treatment in a Small Community Water System

Lorraine C. Backer, Dorothy Stearns, Johnni H. Daniel, Rebecca Tomazin et autres

Arsenic in drinking water poses a threat to public health world-wide. In March 2001, the EPA revised the maximum contaminant level (MCL) for arsenic in drinking water downward from 50 µg/L to 10 µg/L and required all U.S. small community water systems …

Arsenic in private well water and birth outcomes in the United States

Catherine M. Bulka, Molly Scannell Bryan, Melissa A. Lombard, Scott M. Bartell et autres

BACKGROUND: Prenatal exposure to drinking water with arsenic concentrations >50 μg/L is associated with adverse birth outcomes, with inconclusive evidence for concentrations ≤50 μg/L. In a collaborative effort by public health experts, hydrologists, and geologists, we used published machine learning model estimates …

Evaluation of Syndromic Surveillance Data for Studying Harmful Algal Bloom-Associated Illnesses — United States, 2017–2019

Amy M. Lavery, Lorraine C. Backer, Virginia A. Roberts, Jourdan DeVies et autres

Harmful algal and cyanobacterial blooms (harmful algal blooms) are large colonies of algae or cyanobacteria that can harm humans, animals, and the environment (1-3). The number of algal blooms has been increasing in the United States, augmented by increasing water temperatures and …

Evaluation of Electronic Health Records to Monitor Illness From Harmful Algal Bloom Exposure in the United States.

Amy M. Lavery, Lorraine C. Backer, Johnni H. Daniel

Harmful algal blooms (HABs) are the rapid growth of algae that can produce toxic or harmful effects in people and animals. Potential health effects include respiratory illness, gastrointestinal illness, skin and eye irritation, and sometimes more severe toxic effects such as liver …

Machine Learning Models of Arsenic in Private Wells Throughout the Conterminous United States As a Tool for Exposure Assessment in Human Health Studies

Melissa A. Lombard, Molly Scannell Bryan, Daniel K. Jones, Catherine M. Bulka et autres

Arsenic from geologic sources is widespread in groundwater within the United States (U.S.). In several areas, groundwater arsenic concentrations exceed the U.S. Environmental Protection Agency maximum contaminant level of 10 μg per liter (μg/L). However, this standard applies only to public-supply drinking …
