Indiana's water health is a critical issue that deserves attention. Across the state, 80 distinct contaminants have been detected in the water systems, affecting a considerable portion of the population. With 778 water systems in operation, millions of residents rely on these sources for their daily water intake. However, the presence of harmful contaminants such as Total Trihalomethanes, Haloacetic Acids, Nitrate, Molybdenum, and Barium reveals significant vulnerabilities in water quality. Among these, Total Trihalomethanes and Haloacetic Acids alone impact nearly five million residents, underscoring the urgent need to address these threats. Understanding the source and risks of these contaminants is essential for safeguarding public health.

People Impacted: 4,897,229
Total Trihalomethanes are byproducts of water disinfection processes where chlorine interacts with organic matter. While this process helps kill bacteria, TTHMs accumulate as harmful residues. Prolonged exposure to TTHMs has been linked to an increased risk of bladder cancer, liver and kidney damage, and adverse pregnancy outcomes. The staggering number of Indiana residents affected makes TTHMs one of the top contaminants to watch.

People Impacted: 4,875,911
Similar to TTHMs, Haloacetic Acids are another disinfection byproduct formed during the treatment of drinking water. Their presence has been associated with higher risks of reproductive and developmental health issues, as well as potential cancer. With over 4.8 million people in Indiana exposed to HAAs, their prevalence poses a persistent risk to public health and safety.
Water Systems Affected: 426
People Impacted: 4,093,512
Primarily introduced into water supplies through agricultural runoff and fertilizer use, nitrate contamination is a serious concern. High nitrate levels in drinking water are particularly harmful to infants, as they can cause a potentially fatal condition known as "blue baby syndrome." Long-term exposure has also been linked to thyroid dysfunction and some forms of cancer. Nearly 4.1 million Indiana residents face risks from this pervasive pollutant.

People Impacted: 4,044,865
Molybdenum is a naturally occurring metal that can enter water systems through industrial processes and mining activities. While it is essential in trace amounts, excessive consumption can lead to health issues such as gout-like symptoms and kidney dysfunction. With over four million individuals in Indiana potentially exposed, the risks associated with molybdenum are far-reaching.
Water Systems Affected: 565
People Impacted: 3,518,855
Barium is a naturally occurring contaminant that finds its way into water supplies through drilling and mining activities. Elevated barium levels can negatively impact cardiovascular health, causing high blood pressure and weakening of the heart. In Indiana, more than 3.5 million residents are impacted by this contaminant, emphasizing its role as a public health concern.
Exposure to these contaminants has lasting consequences for public health. Cancers, particularly bladder and colorectal cancer, are among the most serious risks linked to Total Trihalomethanes and Haloacetic Acids. Reproductive and developmental health issues, including birth defects and increased miscarriage rates, have been associated with long-term exposure to HAAs. Infants and young children are especially vulnerable to the effects of nitrate contamination, which can lead to life-threatening conditions such as "blue baby syndrome." Additionally, kidney damage, cardiovascular issues, and bone weaknesses are potential risks posed by contaminants like Molybdenum and Barium. Vulnerable populations, such as pregnant women, young children, and the elderly, face elevated risks due to their heightened sensitivity to these pollutants. The state-wide impact of poor water health underscores the urgent need for preventative measures.
Indiana faces significant challenges in maintaining its water quality, with over 80 contaminants detected across 778 water systems. Key areas of concern include disinfection byproducts, agricultural runoff, and industrial pollutants. Addressing these issues requires a multifaceted approach that encompasses stricter water quality standards, advanced filtration technologies, and increased public awareness. By being informed about the risks, Indiana residents can take proactive steps to protect their health and the health of their families. Understanding the scope of the problem is the first step toward building safer and cleaner water systems for all.
