Severity Level Guide

None

CONTAMINANT LEVEL

0 parts per billion (ppb) (ug/L)

At this level, there is no lead reported in your area’s water. While it is still a good idea to take preventative measures and make sure your water filtration system is up to date, you can be confident that your water is safe.

Additional Facts:
The World Health Organization and other public health organizations such as the US Environmental Protection Agency (USEPA) have concluded that there is no safe level of lead in drinking water, and that even low concentrations can cause negative health effects, especially for infants and children.

Trace

CONTAMINANT LEVEL

1-5 parts per billion (ppb) (ug/L))

At this level, a base amount of lead has been reported in your area’s water. Though relatively minimal, the World Health Organization and other public health organizations such as the US Environmental Protection Agency (USEPA) have concluded that there is no safe level of lead in drinking water. It is recommended that a water filtration system be installed to eliminate any possible harm.

Additional Facts:
In Canada and the European Union, the current public health lead limit is under 5 parts per billion (ppb) in drinking water. This is also the level that an NSF International Certified Drinking Water Treatment Unit is required to reduce lead levels to.

Moderate

CONTAMINANT LEVEL

5-10 parts per billion (ppb) (ug/L)

At this level, a large enough amount of lead has been reported in your area’s water that it could be dangerous to your health. It is recommended that you check with an expert or find a water filtration system that will ensure your water is as safe as it can be in your home.

Additional Facts:
This range was formerly considered safe by many public health organizations but now requires an NSF International Certified Drinking Water Treatment Unit for reliable lead reduction.

Problematic

CONTAMINANT LEVEL

10-15 parts per billion (ppb) (ug/L)

At this level, a substantial amount of lead has been reported in your area’s water and is considered a danger to your health. This water should not be consumed if unfiltered. It is recommended that you check with an expert or find a water filtration system that will ensure your water is as safe as it can be in your home.

Additional Facts:
This range requires an NSF International Certified Drinking Water Treatment Unit for reliable lead reduction.

Serious

CONTAMINANT LEVEL

5-10 parts per billion (ppb) (ug/L)

At this level, an excessive amount of lead has been reported in your area’s water. It is extremely unsafe and should not be consumed, especially if unfiltered. It is recommended that you check with an expert at this level or find a water filtration system that will ensure your water is as safe as it can be in your home.

Additional Facts:
This is the US Environmental Protection Agency (USEPA) treatment limit. If lead concentrations exceed 15 ppb in 10% of area sampled taps, the local municipality must undertake a number of additional actions to control lead levels. If the treatment options have been exhausted, the municipality must also inform the public about steps they should take to protect their health.

Keep you and your family safe.
