Testing Your Water for Nitrates

Wells in Lancaster County and other agricultural areas often contain nitrates above the allowable level of 10 mg/l. High nitrates are considered a health concern for infants less than 6 months of age, pregnant women and nursing mothers, so most people need not be concerned. Removal of nitrates can be expensive and therefore it is often easier to use bottled water until the baby is older than 6 months. People in Lancaster County who want to subdivide are often asked to test for nitrates. If this is the case, you need to find out how many samples you need and whether or not you can collect them yourself. To test for nitrates, you will need special containers (small vials, one of which has a preservative in it) and instructions. You can pick up these containers at Lancaster Laboratories at no charge. There is a $29 fee for the test. Your report should be mailed to you in about 2 weeks.
