Yesterday I received the water sample lab results for the pond. The sample was taken at 8:00 a.m. on 9-7-06, air temp 57 degrees, surface water temp 67 degrees, pH 8, cloudy skies and a secchi disc reading of > 5'.
Interesting note about the secchi disc reading. Last month the reading was around 22". A week prior to the sample, our area received a couple of rainstorms. In another thread,
http://www.pondboss.com/ubb/ultimatebb.php?ubb=get_topic;f=17;t=000084;p=1#000010 I talked about taking a water sample after a rainstorm figuring the turbidity would be affected. I was very surprised by the reading.
Test results are :
Alkalinity 114 mg/l
Calcium Hardness 140 mg/l
D.O. 9.0 mg/l
Turbidity 1.6 NTU (nephelometric turbidity units.)
Next summer I will take another sample for comparison. Costs for all 4 tests, $70. I took the sample and delivered it to the lab. Onsite sampling by the lab would of added $30 to the cost.
