FAQ

• Odd taste, coloration or smell can indicate the presence of contaminants.
• Homes built before 1986 are more likely to have lead plumbing and fixtures that can leach into tap water.
• Because private well water is not monitored by testing at a treatment facility, the EPA recommends testing twice a year.
• Stains in sinks and around fixtures can indicate the presence of iron, copper and other minerals.
• Monitor news reports and TBD websites to learn of contamination outbreaks in your area.
• Water quality is constantly changing. Regular retesting recommended.

Not necessarily. While some contaminants, like iron and copper, will produce discoloration, an unpleasant taste, or leave a mineral residue around sinks and fixtures, dangerous contaminants, like lead, bacteria and pesticides can be invisible, odorless and colorless and can only be detected through testing.

Contaminants enter the water supply from many sources, including:

• Naturally-occurring contaminants in soil
  and groundwater.
• Pipes and plumbing fixtures within the home.
• Industrial waste from factories, mining operations, and oil drilling.
• Agricultural pesticides and fertilizers from farms, parks or lawns.

Again, not necessarily. In some cases, drinking contaminated water will produce immediate symptoms, like stomach cramps, diarrhea and nausea. In other cases, such as lead poisoning, the toxin builds up in the body over time, and ill effects can take months or years to become apparent. This is particularly true with pregnant women, where lead can cause birth defects, and young children, who can suffer from developmental problems such as stunted growth and lower IQ.

Hardness is not a health concern, but it can have other undesirable consequences, such as preventing soap from lathering, scaling pots and pans, and damaging water heaters.

How are contaminants regulated?

The Environmental Protection Agency (EPA) regulates the allowable levels of over 90 drinking water contaminants in accordance with the Safe Drinking Water Act. In addition, states are allowed to set their own standards as long as they meet the EPA’s minimum requirements.
Public water systems are required by the EPA to notify customers if they violate EPA or state drinking water regulations, or if they provide drinking water that may pose a risk to consumers’ health. However, in the case of lead, an alert is only issued when more than 10% of a system’s tap water samples show lead concentrations above EPA limits of 15 ppb (parts per billion).

That depends on several factors, including the contaminant, the source, and the concentration. Some options include:

• Call the EPA safe drinking water hotline at 800-426-4791
• Use bottled water for drinking, cooking and brushing until the contamination is removed.
• Install a filtration system certified to remove your specific contaminant.
• Identify the source of the contamination.
• If the source is within the home, consider replacing affected pipes and fixtures.
• If the source is outside the home, contact your local water system.

Bacteria | None
Lead | Below 15 ppb
Pesticides (atrazine) | Below 3 ppb
Pesticides (simazine) | Below 4 ppb
Copper | Below 1.3 ppm
Iron | Below 0.3 ppm
Total Nitrate/Nitrite | Below 10.0 ppm
Nitrite | Below 1.0 ppm
pH | 6.5 to 8.5 ppm
Total Hardness | 50 ppm or less
Total Chlorine | Below 4 ppm

Unfortunately, the crisis in Flint, Michigan is not a unique occurrence. Recent news reports have shown that water systems across the country are in violation of government safety standards.
According to a USA Today investigation, excessive lead levels have been found in almost 2,000 water systems across all fifty states. These systems collectively supply water to over 6 million people. The same investigation revealed that in 180 cases water systems failed to notify consumers as required by law.

CNN recently reported that 18 million Americans live in communities where water systems are in violation of the EPA’s lead and copper rule. The report asserts that many utilities “game the system” by using “flawed or questionable testing methods in order to avoid detecting high levels of lead.”

Bottom line: You can’t assume that your water is free of contaminants unless you test it.

The EPA has created the Drinking Water Mapping Application to Protect Online Source Waters (DWMAPS), an online mapping tool that provides information on water supply conditions across the country.
