Water droplets that fall over land may soak into the ground, fall as snow on the mountain tops, or collect in lakes. True False - Answer True The amount of available surface water depends largely upon groundwater. True False - Answer False In lakes and reservoirs the rapid growth of algae (blooms) will occur when the temperature is right and the water contains enough nutrients to support rapid algal growth. True False - Answer True Proposed groundwater recharge projects must be investigated on an individual basis where the use of reclaimed water involves a potential risk to public health. True False - Answer True Precipitation in the form of rain, snow, hail, or sleet contains few impurities. True False - Answer True Objectionable tastes and odors in the domestic water supply are often related to the occurrence of algal blooms. True False - Answer True By controlling algal blooms and silt loading, it may be possible to consider using direct filtration only instead of complete treatment. True False - Answer True In some cases it may be much more feasible and economical to correct the problems major algal blooms cause by application of chemicals than to limit nutrient availability True False - Answer False Mixing algicide chemicals in their solid forms is a good method of application when citric acid is combined with copper sulfate to prevent the precipitation of copper in alkaline waters.
