Ensuring the safety and quality of drinking water is vital for every household. In Delaware, recent data has highlighted various concerns about water quality, from industrial pollutants to harmful chemicals like PFA's. This article will explore the sources of Delaware's drinking water, the significance of maintaining water quality, and how residents can get a free water test from Aerus Delaware to identify and address potential contaminants.

Overview of Delaware Drinking Water Sources

Delaware's drinking water sources include surface waters such as rivers, lakes, and reservoirs, with the Delaware River and its tributaries being significant contributors. Groundwater from aquifers like the Columbia and Potomac is also crucial for both urban and rural areas, although it can face contamination risks. Municipal water supply systems in Delaware blend surface water and groundwater, managed by local utilities who are responsible for regular testing and treatment processes.

Importance of Drinking Water Quality

Contaminated water poses severe health risks, including gastrointestinal illnesses, reproductive problems, and neurological disorders, making high water quality crucial for public health and the prevention of waterborne diseases. Poor water quality can disrupt daily life, increase healthcare costs, and put vulnerable populations, such as children and the elderly, at greater risk. Ensuring access to clean water is essential for maintaining overall well-being and preventing the spread of harmful pathogens and toxins. This is the reason why Aerus Delaware has launched a program that tests Delaware residents water for free! Find out more here

Recent Data on Delaware Drinking Water Quality

Water Quality Reports (2021-2023)

Recent water quality reports have revealed concerning levels of various contaminants in Delaware's drinking water. For example, the Environmental Working Group (EWG) found that several water systems in Delaware contain levels of PFAS and other harmful chemicals that exceed health guidelines . Additionally, the Delaware Department of Natural Resources and Environmental Control (DNREC) has reported elevated nitrate levels in certain areas, primarily due to agricultural runoff .

Significant Contamination Incidents

Over the past few years, Delaware has experienced several significant contamination incidents. In 2021, elevated levels of PFAS were detected in the water supply of New Castle, leading to widespread concern and calls for improved testing and treatment . Another incident in 2022 involved the detection of high arsenic levels in the groundwater of southern Delaware, prompting immediate action to protect public health .

Areas with Recurrent Issues

Certain areas in Delaware have recurrent water quality issues. For instance, communities near industrial sites often face higher levels of heavy metals and chemical pollutants. Agricultural regions frequently struggle with nitrate contamination from fertilizer runoff. These ongoing problems highlight the need for regular water testing and intervention.

Common Contaminants in Delaware Drinking Water

Industrial Chemicals

Industrial activities can introduce harmful chemicals into water sources. These include solvents, heavy metals, and other toxic substances that can pose serious health risks to consumers.

Pesticides and Herbicides

Agricultural runoff often contains pesticides and herbicides that can contaminate water supplies. These chemicals can affect both human health and aquatic life, making it essential to monitor their levels in drinking water.

Heavy Metals

Heavy metals like lead, mercury, and arsenic can enter drinking water through natural deposits or industrial pollution. These metals are toxic and can cause various health problems, including developmental issues in children.

Bacterial Contaminants

Bacterial contamination, such as E. coli and coliform bacteria, can occur due

to sewage leaks, agricultural runoff, or poor sanitation practices. These bacteria can cause severe gastrointestinal illnesses and other health issues.


Nitrates are often found in water supplies due to agricultural runoff and the use of fertilizers. High nitrate levels can be particularly dangerous for infants, causing a condition known as methemoglobinemia or "blue baby syndrome." It's essential to monitor nitrate levels to ensure they remain within safe limits.


Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals found in various industrial and consumer products. PFAS are persistent in the environment and have been linked to adverse health effects, including cancer, liver damage, and immune system disruptions. Regular testing is crucial to detect and manage PFAS contamination.


Arsenic is a naturally occurring element that can seep into groundwater from geological formations. Chronic exposure to arsenic in drinking water has been associated with skin lesions, cancer, cardiovascular diseases, and diabetes. Ensuring arsenic levels remain below the EPA's maximum contaminant level is critical for health safety.
