Study Notes

Hydrologic Cycle

Represents the natural circulation of water in various forms on, in, or above the Earth's surface.

Evaporation

Process where water vapor enters the atmosphere from surface bodies of water.

Transpiration

Release of moisture into the air by plants through their leaves, similar to sweating.

Precipitation

Water returns to the Earth in forms such as rain, snow, sleet, or hail.

Infiltration

Process whereby water penetrates the soil and ground layers.

Runoff

Water from precipitation that moves over the land and replenishes lakes, rivers, and streams.

Classifications of Water Sources

Surface Water: Includes rivers, streams, and lakes.
Ground Water: Found in wells and springs.
Sea Water: Includes the saline bodies of water.
Precipitation: Encompasses rain, snow, and ice.

Contact Time (CT)

Refers to the duration chlorine is in contact with water for effective disinfection.

Turbidity

Indicates water clarity, where higher turbidity reflects muddy or unclear conditions.

Dissolved Solids

Refers to invisible gases and other substances dissolved in water, essential for water quality assessment.

Total Dissolved Solids (TDS)

Represents the total amount of dissolved solids in water, quantified in parts per million (ppm).

Characteristics of Water

Key indicators include turbidity, color, odor/taste, and temperature.

Color

The color of water is attributed to various colored substances present in it.

Odor/Taste

There is no established standard for odor and taste in water quality.

Temperature

Water temperature affects perception; warm water can taste flat, while cooler water is often more palatable.

Chemical Properties

Key chemical properties include acidity/alkalinity, hardness, corrosiveness, and TDS.

Acidity/Alkalinity

Measured by pH levels; indicates the balance of acids and bases in water.

Hardness

Caused by the presence of salts such as calcium, magnesium, iron, manganese, and various anions.

Corrosiveness

Refers to water's tendency to dissolve metals and other substances due to dissolved gases.

Contamination of Water

Can arise from organic/microbial sources, industrial waste, or chemical, biological, radiological, and nuclear (CBRN) contamination.

Field Water Purification

Aims to ensure water is safe for human consumption through several purification processes.

Multimedia/Ultra/Micro Filters

Filters designed to remove large and small solids using polymer chemicals.

Cartridge Filter

Utilizes a filtration system to eliminate suspended solids after multimedia filtration.

Reverse Osmosis

Separation technique that effectively removes dissolved and suspended solids from water.

Contaminated Water

Water that contains harmful organisms or substances that pose health risks.

Polluted Water

Water laden with hazardous substances such as waste or industrial pollutants.

Palatable Water

Clean in appearance but may not be safe for consumption; lacks undesirable elements like color, turbidity, and odor.

Potable Water

Safe for human consumption; devoid of harmful microorganisms, chemicals, and toxins.

Warning

Alerts users about hazardous situations that may lead to severe injury or death.

Caution

Alerts users to potential equipment damage or mission compromise due to non-compliance.

Water Reconnaissance

A specialized survey to collect data on water sources and storage/distribution options.

A comprehensive approach for managing army maintenance activities.

Field Level Maintenance

Basic operator or crew-level maintenance focused on immediate equipment upkeep.

Sustainment Level Maintenance

Involves repairing components and systems at a more extensive repair level.

Fault

Describes defects in equipment that do not entirely hinder operation.
