Protection Agency (EPA) has a wealth of important
data regarding clean drinking water. These links will
connect directly to specific
pages that are useful for Sonoma County residents. As our
water resource continues to shrink, we run ever greater
risks of contamination. Below are links to lists of known
contaminants, unfortunately some contaminants are regulated
and some are not.

Water Regulations (NPDWRs or primary standards) are legally
