During October, drought improvement is favored for parts of the Southern Great Plains and northern Minnesota and North Dakota along with drought areas of the Virgin Islands and Puerto Rico. In contrast, drought persistence or intensification is forecast for a vast majority of the drought areas affecting the contiguous US and Hawaii. Drought development is forecasted by the end of the month in the Southeast and parts of the Northwest and Hawaii. Drought persistence is also forecasted across the Northwest, Southwest, Midwest, parts of the Southeast, and Hawaii. Drought can have direct and indirect impacts on health—increasing incidence of illness among those living in the affected area and worsening mental health outcomes as livelihoods are challenged.
Drought Affects Health in Many Ways
Drought increases the risk for a diverse range of health outcomes. For example:
Low crop yields can result in rising food prices and shortages, potentially leading to malnutrition.
Dry soil can increase the number of particulates like dust and pollen that are suspended in the air, which can irritate the bronchial passages and lungs.
Dust storms can spread the fungus that causes coccidioidomycosis (Valley Fever).
If there isn’t enough water to flow, waterways may become stagnant breeding grounds for disease vectors like mosquitos as well as viruses and bacteria.
Drought's complex economic consequences can increase mood disorders, domestic violence, and suicide.
Long-term droughts can cause poor-quality drinking water and leave inadequate water for hygiene and sanitation.
As indicated in the map to the left, 1392 counties across 39 states are projected to have persistent/remaining drought or drought development in October. In these counties, the total population at risk is 102,266,696 people and, of those, 1,158,574 people work in agriculture. Of these counties:
332 (24%) have a high number* of people aged 65 or over, living alone.
327 (23%) have a high number of people living in rural areas.
357 (26%) have a high number of people living in poverty.
414 (30%) have a high number of people with frequent mental distress.
288 (21%) have a higher number of adults with asthma.
262 (19%) have a high number of people without health insurance.
222 (16%) have a high number of uninsured children.
388 (28%) have a high number of Black or African American persons.
299 (21%) have a high number of people with severe housing cost burden.
360 (26%) have a high number of people in mobile homes.
360 (26%) have a high number of people with one or more disabilities.
351 (25%) are identified as highly vulnerable by CDC's Social Vulnerability Index.
*“A high number” indicates that these counties are in the top quartile for this indicator compared to other counties
Drought and Arsenic in Domestic Wells

![Map showing the probability of having high arsenic in domestic wells during drought](https://public3.pagefreezer.com:443/content/HHS.gov/17-10-2023T05:13/https://www.hhs.gov/sites/default/files/population-arsenic-concentration.png)
Figure: Map showing the probability of having arsenic >10 μg/L (“high arsenic”) in domestic wells during drought. Arsenic occurs in groundwater due to chemical reactions between the rocks and water, lowering of water levels due to drought may cause chemical changes that release more arsenic from the rocks. Less water could also concentrate existing arsenic in the water. Hotspots generally reflect areas in the U.S. with high observed concentrations including New England (predominantly Maine and New Hampshire), a band in the upper Midwest, the southwest (most notably Nevada, southern Arizona, southern and central California, and isolated regions in all western states), and southern Texas.
Drought conditions can lead to elevated levels of naturally occurring arsenic in the water we drink. The risk of contamination increases the longer that a drought persists. In a study done by U.S. Geological Survey and Centers for Disease Control and Prevention in 2021, researchers estimated that over 9% (4.1 million) of the 44.1 million people in the lower 48 states who use private domestic wells were potentially exposed to unsafe levels of arsenic during drought conditions compared to about 6% (2.7 million people) during non-drought conditions. Chronic exposure to arsenic from drinking water is associated with an increased risk of several types of cancers, developmental issues, cardiovascular disease, adverse birth outcomes and impacts on the immune and endocrine systems.
Resources to Reduce Health Risks Associated with Drought
Drought poses many and far-reaching health implications. Some drought-related health effects occur in the short-term and can be directly observed and measured. But the slow rise or chronic nature of drought also can result in longer term, indirect health implications that are not always easy to anticipate or monitor.
The Centers for Disease Control and Prevention (CDC) Drought and Health site and Ready.gov Drought site have information on the health implications of drought and how to prepare. The U.S. Drought Portal provides data, decision-support products, resources, and information on drought.

The Department of Agriculture offers programs that can help with drought recovery as well as those that can help farmers manage risk and build resilience. The Department’s Climate Hubs feature regional resources including vulnerability assessments and tools and a Climate, Agriculture, and Forest Science Webinar Series.
The U.S. Drought Monitor is an online, weekly map showing the location, extent, and severity of drought across the United States. The Department of Agriculture uses the Drought Monitor to determine a producer’s eligibility for certain drought assistance programs. You can report drought-related conditions and impacts within the U.S. and associated territories to the Drought Monitor.
The Department of Agriculture’s Natural Resources Conservation Service can help farmers conserve water and build resilience to drought, through conservation practices that improve irrigation efficiency, boost soil health, and manage grazing lands.

Drought is a slow-moving hazardous event, so the psychological effects of living through this type of disaster are more subtle and last longer than with other natural disasters. The Substance Abuse and Mental Health Services Administration (SAMHSA) Helpline and Text Service is available 24/7, free, and staffed by trained crisis counselors. Call or text 1-800-985-5990 to get help and support for any distress that you or someone you care about may be feeling related to any disaster.
Funded by the Federal Office of Rural Health Policy within the Health Resources and Services Administration, the Rural Health Information Hub offers several resources about drought and other stressors farmers face, as well as information and resources about farmers' mental health and prevention of suicide among farmers.
Learn more about drought and mental health at the SAMHSA’s Drought site. SAMHSA also has other disaster behavioral health resources, including newsletters and tip sheets. Check out SAMHSA’s newly launched Climate Change and Health Equity site for more information on the behavioral health impacts of climate change, preparing for a disaster, and resources for disaster planning and climate change education.
The CDC’s When Every Drop Counts: Protecting Public Health During Drought Conditions—A Guide for Public Health Professionals is intended to assist public health officials, practitioners, and other stakeholders in their efforts first to understand and then to prepare for drought in their communities. It provides information about how drought affects public health, recommends steps to help mitigate the health effects of drought, identifies future needs for research and other drought related activities, and provides a list of helpful resources and too.
The CDC’s Preparing for the Health Effects of Drought: A Resource Guide for Public Health Professionals supplements When Every Drop Counts and is based on the results of a qualitative analysis of in-depth interviews with public health professionals, a review of state drought plans, and a literature review.
OCCHE’s Referral Guide summarizes resources that can address patients’ social determinants of health and mitigate health harms related to climate change. These resources include social services and assistance programs to which patients can be referred, as well as references for anticipatory guidance and counseling to help patients prepare for potential hazards.
