,Safe Drinking Water Act
Give this one a try later!
Passed by congress in 1974 creating uniform national standards for drinking
water quality to ensure every public water supply would meet minimum
health standards. Set primary and secondary regulations. Created the Total
Coliform Rule, Surface Water Treatment Rule and Lead and Copper Rule
among others.

, A=ordinary combustibles. Wood, paper, cloth trash and plastic.
B=Flammable liquids. Gasoline, petroleum oil and paint.
C=Energized electrical equipment. Motors, transformers and appliances.
D=Combustible metals. Potassium, sodium, aluminum and magnesium.
K=Cooking oils and grease.
How is alkalinity measured?
Give this one a try later!
Alkalinity is measured in terms of carbonate hardness expressed as mg/L of
equivalent calcium carbonate.
Annular Seal(grout casing for deep wells)
Give this one a try later!
To a minimum of 50 ft deep.
Benefit of unidirectional flushing over conventional?
Give this one a try later!
It creates higher velocities that are better able to clean the pipe.
Different types of surface stream flows.
