Alabama's water systems face significant challenges, with 111 contaminants found within the state's 509 water systems. These contaminants affect millions of residents, posing potential health risks that cannot be overlooked. Among these contaminants, six stand out due to their prevalence and dangers: Total trihalomethanes, Haloacetic acids, Manganese, Nitrate, Nitrate and nitrite, and Chloroform. Each of these substances presents unique threats to public health, from organ damage to increased cancer risks. Delving deeper into these contaminants unveils the widespread impact and the urgent need to address water quality concerns in the state.
Number of water systems affected: 487
Number of people impacted: 5,862,781
Total trihalomethanes are chemical byproducts formed when chlorine, used to disinfect drinking water, reacts with natural organic matter. Prolonged exposure to these compounds has been linked to an increased risk of cancer, reproductive issues, and developmental challenges in children.
Number of water systems affected: 471
Number of people impacted: 5,667,616
Like trihalomethanes, haloacetic acids are a group of byproducts formed during water disinfection processes. Regular exposure to these acids can increase the risk of cancer and lead to liver, kidney, and nervous system damage over time.
Number of water systems affected: 444
Number of people impacted: 5,421,636
Manganese is a naturally occurring element often found in groundwater. While essential in small amounts, excessive levels in drinking water can impact brain development in children, lower cognitive functions, and cause neurological symptoms similar to Parkinson’s disease.
Number of water systems affected: 362
Number of people impacted: 5,334,963
Nitrate contamination often arises from agricultural runoff, fertilizers, and septic systems. Elevated levels in drinking water are especially dangerous for infants, leading to a condition called methemoglobinemia or "blue baby syndrome," which reduces oxygen delivery in the blood.
Number of water systems affected: 399
Number of people impacted: 5,212,871
Combining the risks of nitrates and nitrites, these contaminants can be traced to similar sources like agricultural practices and wastewater systems. Long-term exposure may increase risks of cancer and adversely affect cardiovascular and reproductive health.
Number of water systems affected: 327
Number of people impacted: 5,063,536
Chloroform is another disinfection byproduct formed when chlorine interacts with organic matter in water. Classified as a probable human carcinogen, prolonged exposure is associated with liver damage, kidney failure, and an elevated risk of cancer.
While many contaminants pose specific risks, the broader implications for public health are alarming. Increased cancer rates, developmental issues in children, and damage to major organs like the liver and kidneys are among the most concerning health impacts. Vulnerable populations, including children, pregnant women, and the elderly, face heightened risks due to their increased susceptibility to these toxins. Additionally, the long-term effects of exposure to multiple contaminants simultaneously remain a significant area of concern, emphasizing the need for urgent intervention.
Alabama’s water health data reveals both a pressing concern and an opportunity to take action. With over 111 contaminants detected across 509 water systems, millions of Alabama residents face potential health risks daily. Focused efforts on stricter water quality regulations, adoption of advanced filtration technologies, and public awareness about contaminants can pave the way for a safer and healthier future. Protecting access to clean, safe water is an urgent priority that requires both community action and informed decision-making.
