[APD] Re: tapwater NO3 survey

The water from my 150 foot deep well 40 miles NW of Philadelphia, PA, is 
about 20 PPM.  The water is hard and alkaline, and there is no runoff 

The water from a small coldwater stream that drains a swamp also shows
20 ppm.  That water is soft and acid.

I use Jungle "Quick Dip" test kit.   Are there better alternatives?
