Procedure: 1  Divide the slide into two sections with grease pencil. 2  2Place a small drop of distilled water on each area. 3  Emulsify one or two colonies of Staphylococcus on blood agar plate on each drop to make a smooth suspension. 4  The test suspension is treated with a drop of citrated plasma and mixed well with a needle. Do not put anything in the other drop that serves as control. The control suspension serves to rule out false positivity due to auto agglutination. Clumping of cocci within 5-10 seconds is taken as positive.
The IOM report did not specify requirements for water but made general fluid intake recommendations based on survey data of 91 ounces (that's 11-plus cups a day) for women and 125 ounces (15-plus cups a day) for men.

In the OECD countries, the average domestic consumption is approximately 180 litres per capita and per day. range of 20 to 40 liters of freshwater per person per day is generally considered to be a necessary minimum to meet needs for drinking and sanitation alone, according to Peter Gleick, president of the Pacific Institute for Studies in Development, Environment and Security.
