Whatever you learn from the Consumer Confidence Report for your tap water, remember, there is a simple solution. Pure Berkey is the gold standard of water purification, removing 99.99% of Lead, VOCs, Bacteria, Viruses and Drugs. Pure Berkey even removes radiological waste like uranium. Pure water for pennies a gallon. No matter what.

How to Interpret your CCR

Look for the key of abbreviations and familiarize yourself with them. Here’s a common list:

  • Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
  • Maximum Contaminant Level (MCL): The highest level of contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
  • Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
  • Maximum Residual Disinfectant Level (MRDL): The highest level of a drinking water disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
  • Highest Level Detected: This column represents the highest single sample reading of a contaminant of all the samples collected in this calendar year.
  • Range of Detections: This column represents a range of individual sample results, from lowest to highest that were collected during the CCR calendar year.
  • Date of Sample: If a date appears in this column, the Illinois EPA requires monitoring for this contaminant less than once per year because the concentrations do not frequently change. If no date appears in the column, monitoring for this contaminant was conducted  during the Consumer Confidence Report calendar year.
  • Action Level (AL): The concentration of a contaminant that triggers treatment or other required actions by the water supply.
  • Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
  • ND: Not detectable at testing limits
  • N/A: Not applicable
  • Locational Running Annual Average (LRAA): The average of 4 consecutive quarterly results at each monitored sample location. The LRAA should not exceed 80µg/L for TTHM and 60µg/L for HAA5.

There is a difference between Safe and Legal.

Safe are results closer to the MCLG (Maximum Contaminant Level Goal).

Legal are results closer the MCL (Maximum Contaminant Level), the maximum allowed by law.

Water companies frequently say the water is safe to drink, when what they mean is the water is legal to drink. Example: the MCLG for lead is 0; your water company can say they are meeting EPA’s MCL guidelines with 90% of readings at 15 parts per billion (ppb). That’s 15 times1 more than anyone should consume.

1 Pure Berkey understands that you can’t multiply by 0. We hope you get our intended point -15 ppb is a lot more than 0.
