Introduction

From swimming pools to wells, chlorine is a common chemical used to disinfect water sources.

Microbial agents

Helicobacter pylori

Helicobacter pylori is known to cause gastritis and peptic ulcers.
Studies done in Peru1 and Japan 2 have shown the presence of the bacteria in public water sources, proving its possibility as a waterborne microbe.

Cryptosporidium

Cryptosporidium parvum is a type of parasite capable of causing gastrointestinal illness. Unlike Helicobacter pylori, however, Cryptosporidium has been proven to be unresponsive to chlorination (citation needed).

Methods

Success rates

Alternative methods

Scientists are not content with shock chlorination. As technology advances, methods to improve both testing and disinfection are created.
