Childhood Lead Poisoning

A Hidden Problem: Lead Poisoned Children in the United States

A recent study by the California Environmental Health Tracking Program, a program of the Public Health Institute takes a close look at the surveillance and reporting of lead poisoning within the United States. This study takes a fresh look at childhood lead poisoning and the assumption that all children are tested. Learn more at

Legal Epidemiology

Laws and policies are essential to environmental health issues. Legal epidemiology is an emerging field that blends the practice of developing and implementing health laws with the scientific evaluation of how laws can affect health. Legal epidemiology is defined as: The scientific study of law as a factor in the cause, distribution and prevention of disease and injury. 

Legal epidemiological research can cover a wide variety of environmental health law topics such as:

  • Laws limiting exposures to disease-causing substances
  • Laws that regulate the use and disposal of harmful chemicals and materials
  • Laws creating parks and other community spaces
  • Laws establishing new frameworks like Health in All Policies (HiAP)

Local environmental health professionals, in particular, should be aware of legal epidemiological tools because it is harder for them to look across jurisdictions for best practices, due to lack of current information on law and policy. Using legal epidemiology can help with these barriers. Local environmental health professionals who conduct surveillance on their own laws and policies can use that information for evaluation and future program planning.

Webinar Series: An Introduction to Legal Epidemiology

NEHA, in collaboration with CDC's Public Health Law Program, is hosting a 3-part webinar series that examines the use of legal epidemiology to address environmental health. The first webinar will serve as an introduction to legal epidemiology and a discussion of the relationship between environmental health and policy. The second webinar will serve as legal epidemiology training for environmental health practitioners. The third webinar will offer a primer on the Health in All Policies (HiAP) approach and demonstrate how legal epidemiology can be used as a tool in tracking the growth of HiAP laws, policies and programs across the country and identifying current trends.

EPH Tracking Virtual Conference

Environmental Public Health Tracking Virtual Conference The National Association of Chronic Disease Directors (NACDD) has partnered with the Centers for Disease Control and Prevention (CDC)/Environmental Health Tracking Branch (Tracking Branch) to host a virtual conference to 1) raise awareness and knowledge about the environment’s role in asthma and other chronic diseases and 2) highlight collaboration opportunities between state leaders, decision makers and practitioners working in environmental health and chronic disease prevention.

Informatics Resources

The Informatics Resources available here serve to support environmental health informatics programs and data-use activities. These resources showcase data collection, sharing, and use stories and serve to support the implementation of these activities within your own program.  Amongst these resources, you will find online education, a searchable repository of free and low-cost tools, case studies, tools to support the request for proposal process, and more. Through the utilization of these resources, we hope that data can be used to inform and improve programs, policies, and public health.

Environmental and public health informatics is an emerging field that focuses on standardized data collection, sharing, and use. Data is transformed into information that is then used to better inform and develop programs. By moving towards the wider adoption and use of informatics systems, we can expect data-informed decision making that will improve population health.

Local, state, and federal agencies collect environmental health data that may not always be routinely analyzed or used to inform public health initiatives, especially at smaller local-level agencies. Environmental health professionals collect data through inspections, complaint investigations, and community interactions. The incorporation of this data with other public health data has the potential to inform programs in ways that have not yet existed. Imagine a physician taking a patient’s home environment into account when making a diagnosis. Or, imagine using an app to easily assess the safety of an aquatic facility, restaurant, or body art studio. 

Emerging Issues

Environmental health and public health programs, as well as healthcare facilities, have the potential to make an even greater impact on community health through increased data collection and sharing. Opportunities include increased advocacy for resources, establishment of data standards, easier sharing of data internally and across agencies, and development of tools and trainings.

Open Data ImageData and Environmental Health Best Practices Webinar Series: October/November 2020

Build foundational knowledge on open data for your environmental health agency through this new webinar series. If you’ve ever wondered what open data are or how to get more results from the information your agency collects, this webinar series is for you. This 4-part webinar series will feature top open data experts and dive into open data, data management, and data standards for environmental health. 


Environmental Public Health Tracking 

Environmental and public health tracking and informatics is an essential piece of local, state, tribal, and federal agencies as it relates to the status of public and environmental health in this country.  Data is the holy grail of information for local health departments and federal agencies alike for determining what projects to take on next and how to better the community. Some would even suggest that data has been responsible for diverting illness and potentially saving lives. Well, environmental health does save lives, money and protect the future, right? So why wouldn't data

NEHA and the CDC have partnered to help engage local health departments to start sharing data to better inform the community while contributing to a nation-wide network. Environmental Health tracking is about engagement and access and NEHA is constantly working with EH professionals to use data effectively, and share data efficiently. 

CHAT Webinar SeriesCommunications in Environmental Health and Tracking (CHAT) Webinar Series: October 2018–February 2019

In partnership with CDC’s NCEH, NEHA hosted the Communication in Environmental Health and Tracking (CHAT) Webinar Series. This 5-part webinar series explored different communication and outreach strategies to facilitate a tracking program's engagement with traditional and nontraditional partners, impact policy, and work effectively across divisions.

Webinar 1: Communication Tools and Strategies for Tracking Programs to Engage With Local Health Departments: Wisconsin’s Use of Mini-Grant Program

Webinar 2: Communication Tools and Strategies for Tracking Programs for Working Across Divisions: Vermont's Testing for Lead in School Drinking Water Pilot Project

GREAT Programs Webinar logoGREAT Programs 

NEHA partnered with CDC Tracking on the GREAT Programs webinar and resources focused on utilizing student interns in program activities. The webinar highlighted two CDC grantee tracking internship programs at the New York State Department of Health and the Wisconsin Department of Health Services. The speakers discussed their experiences developing and supervising internship programs, one of which has developed into a funded program with promotional materials.

Advances in Causal Understanding

New molecular and bioinformatic approaches have advanced understanding of how molecular pathways are affected by exposure and the molecular networks involved in disease. However, these advances are often not yet deemed sufficient to establish causality for public health risk assessments; regulators still rely primarily on traditional apical endpoints, such as those endpoints observed in animal studies.
