Drinking Water

Drinking water every day is important for good health.

Water keeps the mind and body healthy. It is important to drink water each day so that your body can keep a normal temperature, lubricate and cushion joints, protect your spinal cord and other sensitive tissues, and get rid of wastes through urination, perspiration, and bowel movements. The amount of water you need depends on your age, health, and lifestyle.

Sometimes drinking water contains substances that can affect our health.

About two-thirds of Wisconsinites use groundwater as their drinking water source. Groundwater is part of the water cycle. When it rains or when snow melts, water seeps into pores and cracks in the soil and is stored underground in aquifers. Aquifers can contain harmful substances from natural and human-made sources from activities that happen on the land.

About one-third of Wisconsinites get their drinking water from Lake Superior, Lake Michigan, or Lake Winnebago. These lakes can also be affected by contamination through storm water runoff and .. disposal.

We all have a part to play in making sure our drinking water is safe and healthy.
