Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems.

Remember that the glomerulus is the initial filtering sieve of the nephron.
Mars2501 [29]
Filtration rate = 125 mL/minute = 0.125 L/min
Minutes in a day = 24 hours x 60 minutes per hour
Minutes in a day = 1440 
Total filtrate per day = 0.125 x 1440 = 180 L

Number of 2 L bottles to be filled = 180 / 2
= 90 bottles

This value is very large and we do not produce this much urine in a day. This means a portion of the fluid is being reabsorbed.

Absorption.
