Wkat are Public Healtk Goals?
i0i0o*'
J
•Public Health Goals (PHGs) are water quality values
established by Cal/EPA
• Unlike the Maximum Contaminant Levels (MCLs) that
water systems are required to comply with, PHGs do not
consider analytical detection capabilities, available
treatment technologies, benefits or costs.
• PHGs are non -enforceable and are not required to be
met.
• PHGs are goals identifying extremely small risks that are
posed by constituents tested in potable water.

RecommeKdatiovis for Furtker Actiovt
The City's drinking water meets all State and Federal
drinking water quality standards set to protect public
health.
• To further reduce the levels of the constituents that are already
significantly below the health -based Maximum Contaminant Levels
(MCLs) established to provide "safe drinking water", additional costly
treatment processes would be required.
• The effectiveness of the treatment processes to provide any
significant reductions in constituent levels at these already low
values is uncertain.
• The health protection benefits of these hypothetical reductions are
not at all clear and may not be quantifiable.
• Therefore, no further action is proposed.;;
