2.0 Materials and Methods
2.1 Teet Effluent
The test effluent vas delivered to ERT via Greyhound Bus
Lines on May 18, 1988. The 20-liter sample, labeled "Pond 002B,
G.E. Mine Discharge" was received packed in ice and vas
designated ERT sample 8 361. The effluent was chemically
characterized as follows: hardness, 8 mg/L ae CaCO,; alkalinity,
717 mg/L as CeCO,; and conductivity, 1,150 umhos/cm.
2.2 Dilution Water
Dilution water vas reconstituted water prepared to obtaln a
hardness end alkalinity similar to the actual receiving eater
(Purgatoire River). A 500-mL sample of the Purgetoire River
voter (ERT sample 8362) wee delivered to ERT with the effluent
end characterized as follows: hardness, 110 mg/L es CeCO,; and
alkalinity. 94 mg/L ee CaCO,. The reconstituted dilution water
(ERT RW 875) vas prepared according to the USEPA (1985) method
for preparation of synthetic freshwater (modified to match the
characteriatice of the receiving water) and had the following
cheracteristlce: hardness, 122 mg/L es CeCO,; elkelinlty, 107
mg/L ea CeCO,; and conductivity, 385 umhos/cm.
2.3 Test Oroanisme
Ceriodaohnie sp. were obtained from ERT's in-house culture
(ERT lot 8051788). On the day prior to test initiation, gravid
females were isolated in culture water at teat temperature. On
the day of teat initiation, < 24-hour old neonates were collected
