1. An apparatus for containment of collected materials, the apparatus comprising: at least one storage tank, the storage tank having a hollow interior region with a first section, a second section and an engagement line therebetween;a bladder disposed at the engagement line, the bladder being operable to contain the material therewithin;at least one opening formed in the bladder to allow the materials to enter or exit the bladder;an access port disposed on the storage tank and accessible to the hollow interior region of the tank;a vacuum pump attachable to the access port and operable to regulate the pressure of the hollow interior region of the tank, external to the bladder; anda mounting ring disposed on an interior surface of the tank at the engagement line, wherein the bladder is affixed to the mounting ring and the position of the mounting ring is adjustable along the interior surface. 2. The apparatus of claim 1, wherein the vacuum pump is operable to pull a vacuum on the hollow interior region of the tank, external to the bladder. 3. The apparatus of claim 1, wherein the vacuum pump is operable to pressurize or depressurize the hollow interior region of the tank, external to the bladder. 4. The apparatus of claim 1, wherein the bladder is impermeable to and compatible with the material. 5. The apparatus of claim 1, wherein the bladder is emptied when the vacuum pump pressurizes the hollow interior region of the tank, external to the bladder. 6. The apparatus of claim 1, wherein the bladder is filled when the vacuum pump depressurizes the hollow interior region of the tank, external to the bladder. 7. The apparatus of claim 1, wherein the engagement line divides the hollow interior region such that the first section and the second section of the storage tank have substantially the same volume. 8. The apparatus of claim 3, wherein the bladder is substantially disposed within the first section when the storage tank is pressurized and the bladder is substantially disposed within the second section when the storage tank is depressurized. 9. The apparatus of claim 1, wherein the storage tank is disposed on a vacuum truck. 10. The apparatus of claim 1, further comprising one or more carbon scrubbers disposed on a exhaust stream of the vacuum pump to absorb collected materials from the exhaust stream. 11. A method of loading materials into a bladder located within a vacuum tank, the method comprising: providing a hollow interior region within the vacuum tank, the hollow interior region having a first section and a second section;providing a mounting ring on an interior surface of the tank, wherein the bladder is affixed to the mounting ring and the position of the mounting ring is adjustable along the interior surface;locating the bladder within the first section of the hollow interior region;providing at least one opening on the bladder for the materials to enter the bladder;depressurizing the hollow interior region external to the bladder to fill the bladder; andpulling the materials into the bladder such that the bladder relocates from the first section to the second section. 12. The method of claim 11, further comprising: providing an engagement line within the hollow interior region that divides the first section and the second section into approximately equal volumes. 13. A method of unloading collected materials from a bladder located within a vacuum tank, the method comprising: providing a hollow interior region within the vacuum tank, the hollow interior region having a first section and a second section;providing a mounting ring on an interior surface of the tank, wherein the bladder is affixed to the mounting ring and the position of the mounting ring is adjustable along the interior surface;locating the bladder within the second section of the hollow interior region;providing at least one opening on the bladder for the collected materials to exit the bladder;pressurizing the hollow interior region external to the bladder to empty the bladder; andpushing the collected materials from the bladder such that the bladder relocates from the second section to the first section. 14. The method of claim 13, further comprising: providing an engagement line within the hollow interior region that divides the first section and the second section into approximately equal volumes.
