     Could someone help me determine if my town tap water is acceptable for
     growing & rearing CP's (esp. Sarracenia, Nepenthes, Cephalotus,
     Heliamphora, Drosera & Dionea)? Listed below are values relating to
     hardness, pH, and some salts; no info on total solids. The water is
     fairly soft, but the water treatment plant adds sodium ash to buffer
     the naturally low pH. If this water isn't great, would RO work well
     under these conditions?
     
     pH 7.2 - 7.3
     Alkalynity 18-20 mg/L
     Hardness <30 mg/L
     Sulfates 10 mg/L
     Sodium 8.3 mg/L
     Nitrate 1.3 mg/L
     Nitrite <0.1 mg/L
     
     Thanks in advance,
     
     Ted DeWitt
