| We've done this before out of curiosity. One sample pulled by us. Use a 8 foot PVC pipe with a valve at the bottom and dip the pit. One sample pulled from one pump out spot. Another sample was pulled by the local coop. I'm not sure how they pulled the sample but was told they pulled samples from 4 different pump outs. Last sample was pulled by the owner of the site. He took a cup and scooped some out of a pump out. All 3 samples came back within 5lbs/1k of N | |
