How does water quality affect food?

Water quality can be affected by poor planning of industrial sites, animal farms, and barnyards and feedlots.

Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. Groundwater, for example, has been considered one of the safest sources of water. However, depending on field location and field size, it may not be possible to use water from these sources for irrigation.
