Drinking Water Tester

For a science project, I test 3 lakes, Rappahannock River, Potomac River, the Bay and my Chespeake control variable, I'll be drinking water analysis. I am looking for a tester kit water under $ 30 that tests up to 12 times and testing for nitrogen and phosphorus. I just want a straight forward easy to use kit! Thank you! 10 points to best!

You gotta be kidding. For a kit that tests for a single parameter, you must pay more than you want. The only chance to go to an aquarium shop and see what they have in the way of testing. You receive the accuracy or precision, but the results could be sufficient for your needs.
