PurTest� BACTERIA, NITRATE, NITRITE test kits use EPA standards to easily check the safety of water. PurTest� has been used and tested by health departments, utilities and inspectors.
PurTest� is laboratory certified to accurately detect the presence of coliform bacteria, including E. coli. One test per kit.
Water experts recommend testing home water at least:

   * Once a year for municipal water users
   * Twice a year for well water users
   * Four times a year for those with low immunities (such as HIV patients), or for anyone on chemotherapy
   * Whenever you suspect a problem or a problem is reported in your area

     The cleanest, best tasting water may contain undetected contaminants. Water contaminated with harmful bacteria, nitrates or nitrites can cause diarrhea, cramps, nausea, headache, serious illness, even death.
     PurTest� NITRATE & NITRITE instantly detect potentially harmful levels of these pollutants, which for infants may cause a sometimes fatal "blue baby" condition.

     Nitrate and Nitrite results within 60 seconds; Bacteria test results within 48 hours.
