PWTA Contaminants
Below is a brief list of contaminants that are tested for by RAdata’s well water test. Many of these contaminants are required to be tested by the 
Prive Well Testing Act. For more information about which tests are required for your home, please see our County Parameters Checklist.

| Treatment: | UV Light |
Nitrate
| Effects: | Infants who drink water containing nitrates could become seriously ill and, if untreated, die. |

Iron

| Treatment: | Water Softener |
Manganese
| Effects: | Manganese is generally not considered a health problem in drinking water. It is more of an aesthetic issue because it causes brownish water and stains clothing and bathtubs. |

pH
| Effects: | Low pH water is acidic and could eat away at the plumbing system, leaching metals such as lead or copper in the plumbing into the drinking water. |
| Treatment: | Neutralizer |
VOC’s

Lead
