FIELD TRIP TO HOBBLE CREEK MIDDLE SITE
Tuesday 23, Oct 2007
TEST RESULTS (Overall Sampling Time: from 1:53 pm to 3:40 pm)
		NUMBER OF SAMPLE
PARAMETER	READINGS	1	2	3	OBSERVATIONS
Silica	1	> 8	> 8	> 8	Minimum detection limit: 0.05 ppm.                                              Readings of silica were out of range. The kit used to measure this parameter was low range and the contents of silica in the river exceeded 8 ppm, even after diluting the sample 2:1
	2	> 8	> 8	> 8
	3	> 8	> 8	> 8
Nitrate	1	6.99	6.38	6.60	Minimum detection limit: 0.1 ppm.                                           Sampling time: 2:03 pm
	2	6.95	5.63	6.82
	3	6.55	6.07	6.73
Phosphate	1	0.04	0.04	0.05	Minimum detection limit: 0.05 ppm.
	2			0.05
	3			0.06
Lead	1	0	0.00	0.10	Minimum detection limit: 0.1 ppm.                                              There was no  presence of lead in the water. These results seem reasonable because we do not know of any potential sources of metals polluting Hobble Creek

	3	0.32	0.09	0.15
Iodine	1	0.61	0.22	0.4	Minimum detection limit: 0.2 ppm.                                          Sampling Time: 3:20 pm
	2	0.54	0.21	0.31
	3	0.53	0.22	0.39
