What is the difference between the floor to ceiling height and the floor height? Solution The difference between the floor to ceiling height and floor height is that the floor to ceiling high is measured from the floor to the underside of the roof, and floor height is measured from the floor to the underside of the lowest hanging object on the ceiling, whether that be a light or a sprinkler or a beam..

1. What is the difference to be found between surface waters and the waters
underground ?
Solution
SURFACE WATER: Surface water is just what the name implies: it is water found in a river,
lake or a superficial cavity of some kind, including dug wells. Surface water is exposed to many
different contaminants, such as animal wastes, pesticides, insecticides, industrial wastes, algae
and many other organic materials. Even surface water found in a pristine mountain stream
possibly contains giardia or coliform bacteria from the feces of wild animals, and should be
boiled or disinfected by some means prior to using it. Many residents of Vancouver Island have
dug wells that they’ve been using without incident, but as our area becomes denser in
populations, the risk of contamination grows. We can treat ground water with an ultra-violet
filter that uses light to kill off harmful bacteria.
GROUND WATER: Ground Water is that which is trapped beneath the ground. Rain that soaks
into the ground, rivers that disappear beneath the earth, melting snow are but a few of the sources
that recharge the supply of underground water. Because of the many sources of recharge, ground
water may contain any or all of the contaminants found in surface water as well as the dissolved
minerals it picks up during its long stay underground. Waters that contains dissolved minerals,
such as calcium and magnesium above certain levels are considered "hard water".
