What does DLR mean?
DLR stands for Detection Limits for Purposes of Reporting.
DLRs are levels for constituents set by SWRCB-DDW
based on scientific testing capabilities. Values below
DLR are reported "ND," meaning "Not-Detected."
TIP: Utilize the DLR when “ND” is listed in the tables to
determine the highest value possible for a constituent.
What is the Maximum
Contaminant Level (MCL)?
The MCL is the highest level of a contaminant that is allowed
in drinking water, as determined by regulatory standards.
To evaluate a contaminant, review the report tables, find the
specific contaminant, and check its allowable MCL. Next,
compare this MCL to the level listed in the data chart.
TIP: Compare the MCLs for each contaminant to the levels
noted in the data charts. MCLs are drinking water standards,
i.e; required limits, while PHGs are recommendations.
What does the PHG column mean?
The PHG column represents the Public Health Goals
set by the California Environmental Protection Agency.
These goals indicate the level at which a contaminant
poses no known or expected health risks.
TIP: Compare the PHGs for each contaminant to the
levels noted in the data charts. Public Health Goals can
differ from MCLs and not all PHGs have a corresponding
maximum level stated. MCLs are drinking water standards,
i.e; required limits, while PHGs are recommendations.
What does ND mean?
ND means the constituent being tested
was “Not Detected" above DLR.
