TABLE 3.
Oocyst recovery efficiencies from seeded 10-liter samples that required no pH adjustment prior to IMS capture
| Water sample source | pH during oocyst capture | Oocyst seed densitya | Turbidity (NTU)b | Recovery efficiency (%)c |
|---|---|---|---|---|
| San Juan River | 7.00 | 983 | 5.7 | 68.3 |
| Fountain River | 7.00 | 146 | 6.9 | 62.0 |
| Arkansas River | 7.00 | 7,079 | 12.0 | 84.0 |
| Rio Grande | 7.00 | 83 | 3.9 | 74.1 |
a
Values are numbers of oocysts per 10 liters.
b
NTU, nephelometric turbidity units.
c
The mean oocyst recovery efficiency was 72.1% (SD = 8.0%).
