1. A portable liquid purification system comprising:a container having a surface defining an interior volume, said container having a bottom with a recess defined therein and a top including a opening for introducing liquid into the interior volume;an ultraviolet light source comprising a housing having an upper surface that is at least partially transparent to ultraviolet light, said source configured to be inserted into said recess such that said source is disposed substantially within said recess, said source further comprising a power supply disposed within said housing and an ultraviolet light bulb disposed within said housing and selectively powered by said power supply, said source being selectively operable to project ultraviolet light through said upper surface and into said interior volume; andan ultraviolet light sensor disposed on said surface of said container such that a portion of the ultraviolet light passing through said interior volume is detected by said sensor, said sensor having an indicator operable to indicate when a predetermined quantity of ultraviolet light has been detected by said sensor such that the liquid in the container has received a predetermined dose of ultraviolet light. 2. The portable liquid purification system according to claim 1, wherein said source is disk shaped and said upper surface is generally flat. 3. The portable liquid purification system according to claim 1, wherein said container is generally cylindrical and said bottom comprises an end of said cylindrical container and has a diameter, said recess extending across substantially the entire diameter of said bottom. 4. The portable liquid purification system according to claim 1, wherein said recess is open to said interior volume such that said upper surface of said source is in contact with said interior volume and said source seals said bottom of said container. 5. The portable liquid purification system according to claim 1, further comprising a rigid, liquid impermeable material reflective of ultraviolet light lining the inside of said container. 6. The portable liquid purification system according to claim 1, said container being formed from a material generally opaque to ultraviolet light. 7. The portable liquid purification system according to claim 1, wherein said upper surface of said housing comprises a transparent lens, the remainder of said housing being generally opaque to ultraviolet light. 8. The portable liquid purification system according to claim 1, wherein said recess includes threads and said housing includes threads such that said housing threadingly engages said recess. 9. The portable liquid purification system of claim 1, wherein said ultraviolet light source extends into said container such that said source is immersed in liquid during operation and is in thermal contact with the liquid.
