Arsenic is a naturally-occurring metal found in many water supplies
throughout the country. The Environmental
Protection Agency (EPA), which oversees federal water quality
standards, lowered the acceptable level of arsenic in municipal
water supplies from 50 parts per billion (roughly a pinch of salt
in an Olympic-size swimming pool) to 10 parts per billion.
This new standard is not expected to affect the
Las Vegas Valley Water District. Our water already surpasses
the revised standard.

Report to learn more about arsenic and our water supply, or
