22. Water clarity and turbidity Secchi disc Secchi depth is a measure of the clarity or turbidity of the water. Secchi depth is measured using a circular plate, called a Secchi disk, which is divided into quarters painted alternately black and white. The Secchi disk is lowered into the water until it is no longer visible, and that depth is measured. Secchi depth values that are high indicate clearer water, and low Secchi depths indicate high turbidity.
23. pH Level pH, in simple terms, is a chemical measure of whether or not something is an acid or a base. It is measured on a log scale of 0 to 14, with each unit representing a ten-fold change. A pH of 7 is considered neutral and a range of 5.5 to 8.5 is usually tolerated by most aquatic organisms.
24. Dissolved oxygen An example from the deep-water mid-Channel Chesapeake Bay showing low dissolved oxygen (DO) in the summer. The amount of oxygen dissolved in water is probably the single most important measure of habitat quality; without oxygen, all of the living resources familiar to us perish. Dissolved oxygen (DO) is measured as a concentration (mg/l – milligrams per liter). A measure of 5 mg/l is considered low; most of the more visible organisms will not survive in water of less than 1 mg/l for more than a few hours.

26. Biological water quality monitoring Biological monitoring or bio-monitoring evaluates the presence, absence, and abundance of certain organisms in the stream. This type of monitoring gives an overall assessment of the health of the stream based upon the ecological conditions of the stream--what critters are making the stream their home.
41. To Join the GLOBE Program Teachers and other educators who wish to lead students in GLOBE need to attend special workshops in order to fully participate in the program. Look up currently scheduled workshops and if you do not find a workshop you can attend, contact a Partner . Click here to see an agenda.
50. If I Could Be Water If I could be water I wouldn't be a pond Muddy and brown, I wouldn't be an ocean Big and alone, I wouldn't be rain Falling again and again, I wouldn't be ice Cold and frozen, I would be a river Long, wide and free.

WATER, Our Planet’s Most Precious Resource. Welcome to today’s presentation on WATER, Our Planet’s Most Precious Resource. This presentation provides a brief overview of some basic water resource concepts, with particular emphasis on nonpoint source pollution. The presentation will identify our water demands, define point and nonpoint pollution as well as identify ways we can address water quality concerns in our own community.
