Nuclear waste, but depends on what you mean...
Unpolluted freshwater supplies are commonly referred to as "pristine" or "clean" water sources. These include natural springs, glaciers, and untainted lakes and rivers that have not been contaminated by pollutants or human activities. Such sources are crucial for maintaining ecosystems, human health, and providing safe drinking water. Protecting these pristine waters is essential for environmental sustainability and biodiversity.
Water quality affects human health. One should consume clean water.
Water Security is the protection of adequate water supplies for food, fiber, industrial, and residential needs for expanding populations, which requires maximizing water-use efficiency, developing new supplies, and protecting water reserves in event of scarcity due to natural, manmade, or technological hazards.
An underwater volcano can potentially create tsunamis, disrupting coastal communities and posing a threat to human life. The release of gases and chemicals from the volcano can also affect water quality, impacting marine ecosystems and potentially affecting human health if contaminated seafood is consumed. Additionally, underwater volcanic activity can create hazardous conditions for ships and divers in the vicinity.

It has too much salt; it can be toxic.
Some examples of toxic materials that can pose a threat to human health and the environment include lead, mercury, asbestos, pesticides, and certain types of industrial chemicals. These substances can cause a range of health problems, from respiratory issues to neurological damage, and can also contaminate soil, water, and air, leading to environmental harm.

There is less fresh water available due to factors such as increased demand for consumption, pollution, climate change leading to altered precipitation patterns, and mismanagement of water resources. These factors have contributed to dwindling supplies of fresh water for human use and ecosystem health.

Shrinkage
some threats would be no water because it is all frozen and you need water to live.
The greatest threats to groundwater supplies include contamination from agricultural activities, industrial processes, and improper waste disposal. Over-pumping of groundwater, leading to depleted aquifers, is also a significant threat. Climate change can exacerbate these issues by altering precipitation patterns and increasing the risk of contamination events.
Climate change has led to increased temperatures and changes in precipitation patterns, affecting water availability and quality. Human activities such as pollution and over-extraction have also significantly degraded water quality in many regions. These changes pose a threat to ecosystems, human health, and agricultural productions that rely on clean water sources.
