Water Debate!!

[doc111]

my tap is 350ppm and it works great.

people way overthink this weed growing thing. like you need a phd to grow the shit.

Mine is over 600 ppm. I had issues that I couldn't seem to solve. I switched to RO water...Presto, no more problems.

thats illegal if its tap water. they have to pump water thats 500ppm or less through municipal lines according to law. unless thats your well water.

I disagree. TDS is considered a secondary standard by the EPA, at 500 ppm. It is not enforceable. It is considered a cosmetic inconvenience. States may individually make law regarding water qualiy, but the EPA doesnt care if your municipal TDS is 1200 ppm. Because TDS doesnt tell us what the individual ppms are (could be arsenic, could be calcium), they dont enforce it.

And even if the municipality violates a primary drinking water standard, such as arsenic, cyanide, etc, the municipality can still serve the water to the public as long as they inform them what contaminants they have and what the risks are. They do this by sending a letter to every address they service saying "the EPA requires us to inform you that you have xyz contaminant at 123 ppms above the mcl. The known side effects are abc and you may want to consider an alternative source for your drinking water such as bottled water"

Here maybe this will help:

National Secondary Drinking Water Regulations


National Secondary Drinking Water Regulations (NSDWRs or secondary standards) are non-enforceable guidelines regulating contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does not require systems to comply. However, states may choose to adopt them as enforceable standards.

• National Secondary Drinking Water Regulations - The complete regulations regarding these contaminants available from the Code of Federal Regulations Web Site.
• For more information, read Secondary Drinking Water Regulations: Guidance for Nuisance Chemicals.

It's municipal and you would think it's illegal but our water is so hard it's ridiculous.

Also silkwill13, we try to take some pride in our grow and do the best for the best smoke. But if you want to just do little and get what you get thats cool. But not for us (or at least me).
But thanks for you info...

As for everyone else thanks for the help. I will just stick with my RO water that I have been useing.
