    Unhappy

    Hi Guys & Gals,
    I just got my local tap water qualtiy table. I've been buying my water since the beginning, but now I'm not so sure I need to. Check this out:

    Nitrate: .63 ppm
    Copper: .249 ppm
    Lead: 12 ppB

    These are the only possible contaminants listed in the report. Other comounds they list that were not found are nitrites, total coliform, inorganic compounds, Volatile organic compounds and radioloical (I assume compounds, but they don't say).

    Is there anything they didn't test for that I sould be concerned about? My tap water seems pretty pure, and it would sure save me a lot of aggrivation if I could just use it.
    Thanks for any input,

    Question

    Hi Schloaty,

    What did it say about calcium content? What did it say about pH? Even with the low content on the mineral and nitrogen elements you mention, you still might have hard (high calcium) and alkaline (high pH) water. Plus the total dissolved solids (tds) or conductivity of the water might be high due to adding up all the various minerals in the water. Soft acid water fish not only like low calcium in the water and a low pH but they need low tds too. I have a sneaky feeling cp's are similar as rain water is soft and acid with a low tds count.

    Thanks for the response. I know that our PH is 7 (neutral) because we just tested it. However, I don't know about the calcium. We may have hard water, as the previous owners put in a water softener....I'll have to check with our water company on our TDS.

    Never ever water plants with water processed through a water softener. The sodium will poison the plants.

    Question

    Hi Schloaty,

    Yeah, if they put in a water softner (the salt exchange kind) they would pretty much condemn your water as being hard (full of calcium). A 7 pH reading is pretty good so maybe the calcium is fairly low too which would mean that you'd get alot of mileage out of a home RO unit.

    One method to increase RO performance is to run the water through a sodium water softener first. The RO filter has a much easier time blocking sodium than it does calcium. My only fear is if something goes wrong with the RO unit and the softened water hits the plants there would be a huge problem. So if you set up a system running softened water through an RO unit you really need to be diligent about monitoring quality.

    OK! I got a more detailed report from the water dept:
    There is also in our water:

    Calcium .2 ppm
    Hardness(CaCO3) .911 ppm
    Magnesium .1 ppm

    Do you guys know if these levels of these mineral will have an impact?

    Hey Shloaty,
    Here's my water, which I drink and use for all my plants, though I think it is one reason the vft's always die [img]http://www.**********.com/iB_html312/non-cgi/emoticons/biggrin.gif[/img] :

    Nitrite: 0.5-0.8 ppm
    Copper: 0.17 ppm
    Lead: 2 ppB
    Calcium: 23 ppm
    Hardness: 120 ppm
    Magnesium: 15 ppm

    I'm not sure why some of the our numbers are so different (especially the hardness), but yes this is what I use for all the plants.
