Arsenic Poisonin Chronic arsenic poisoning results from drinking contaminated well water over a long period of time. Many aquifers contain high concentra tion of arsenic salts.The World Health Organization recommends a limit of 0.01 mg/L (10ppb) of arsenic in drinking water.

What is in your water?
Stage 1ClarificationRiver water passes through a process called “clarification,” in which silts and clays are removed. This stage involves the addition of treatment chemicals (coagulants) which form clumped particles called “floc,” which are then physically removed by gravity sedimentation. During this phase the water is also treated withpowdered activated carbon to improve the taste. Stage 2FiltrationThe clarified water next passes slowly through coal, sand and gravel filters in order to remove the fine particles and microorganisms. PWSA draws its water from the Allegheny River. No ground or well water is used. Approximately 70 million gallons of water are treated each day at our drinking water treatment plant. The plant is capable of producing over 100million gallons of water per day. The treatment process takes 3 full days and consists of 3 separate stages:
Stage 3 DisinfectionThe filtered water is treated with chlorine in order to ensure removal of any harmful microorganisms. During this process, several additional chemicals are added to complete treatment. These include sodiumcarbonate to adjust the pH of the water and fluoride to prevent cavities in children’s teeth.

CLIMATE Similar to a Sponge Filter, the Allegheny River site allows for a downward water flowage and an upward wind flow allowing for a push of filtered water perpendicular to the river.

PRECEDENT Indian Step Wells The wells hold water that may be reached by descending a set of steps. They are covered and protected by the multi-storied structure. These stepwells are are perfect examples of storage and irriagation tanks that provide a facility to obtain water. Although this precedent is a great system, the Allegheny river is collected by a flat topography.
