Water with a high total dissolved solids value will necessarily have a high turbidity value. T. F.

If water has high salinity, it will also have high hardness. T. F.

COD is a parameter used to quantify the total organic matter in water. T. F.

The BOD5 test is carried out using chemical oxidizing agents. T. F.

Water turbidity is caused by suspended solids and colloidal particles. T. F.

Hardness, conductivity, and pH are important parameters to control in water intended for industrial use, in cooling circuits and boilers. T. F.

Given a discharge of domestic wastewater, the dissolved oxygen content will be equivalent to that of natural waters. T. F.

Suspended matter in water is removed by coagulation processes followed by filtration. T. F.

Phosphates contained in urban wastewater will be reduced primarily in the tertiary stage of a conventional wastewater treatment plant. T. F.

Coagulation-flocculation processes decrease water turbidity. T. F.

In tertiary water treatment, activated carbon is used to remove undegraded organic compounds. T. F.

Facultative lagoons have areas that function under aerobic conditions and others under anaerobic conditions. T. F.

Within lagoon processes, aerobic lagoons are usually very deep to increase the amount of dissolved oxygen in the water. T. F.

CFCs are very stable compounds, and their bonds are broken by ultraviolet radiation. T. F.

Ozone is a tropospheric pollutant. T. F.

A concentration of SO2 in air of 2000 ppm means that there are 2000 cm³ of SO2/m³ of air. T. F.
