Went with T A&M for this round of testing. Two samples taken. One right from dock near lime pile, the other out 150 yds away from it. Very minor differences between the two.

Alk 20/20
PH 5.15/5.23
Cond 20/18
Hardness 9/10

P <.01/<.01
N .03/.02

These samples were not preserved or kept cool, just a quick grab in recycled multi rinsed Powerade bottles.
