| Argonide Corp./ | Under a Phase I EPA SBIR we have developed a       |
|                 | sorbent for Arsenic III and V consisting of a nano |
| Aflox GR-3      | alumina fiber enhanced with a form of iron. The    |
|                 | sorbent has a high dynamic capacity @ 50 ppb over  |
|                 | pH ranges of 6.5-8.5. Dynamic sorption capacity    |
|                 | has been modeled and there is good agreement       |
|                 | between experimental and predicted data over the   |
|                 | concentration and pH range of interest, and as a   |
|                 | function of bed depth and flow velocity.           |

| ARCTECH, Inc./  | Humasorb (2), a U.S. patented technology based on  |
|                 | natural organic humic acid removes arsenic and     |
| HUMASORB        | other multiple toxic metals and organics in a low  |
|                 | cost system for small scale and home use.          |

| HydroGlobe/     | MetSorb is a patent pending nonregenerable         |
|                 | adsorbent, with extremely high capacity (20%) for  |
| Metsorb         | removal of both Arsenic III and V from water. The  |
|                 | kinetic performance is also excellent with over    |
|                 | 40,000 bed volumes of capacity at 50 ppb As and 1  |
|                 | minute EBCT.                                       |

| Magnesium       | MEI has developed a series of novel adsorbent      |
| Elektron, Inc./ | media for the purification of contaminated water.  |
|                 | These zirconium-based media exhibit a wide range   |
| Isolux          | of improved performance in removing arsenic,       |
|                 | chromium (III & VI), copper, and other metal and   |
|                 | non-metal ions from drinking water, industrial     |
|                 | process streams, and groundwater applications.     |

| Kinetico Inc.   | Kinetico provides several technologies including   |
|                 | Coagulation Macrolite ceramic media filtration,    |
|                 | iron based and modified activated alumina          |
|                 | adsorptive media, Ion exchange and POU cartridges  |
|                 | and RO's. This wide variety of products allows us  |
|                 | to evaluate a water supply and determine the best  |
|                 | fit.                                               |

| Univ. of        | Polymer enhanced ultrafiltration (PEUF) consists   |
| Oklahoma        | of complexating arsenic ions with a cationic       |
|                 | water-soluble polymer, followed by removal of the  |
| Norman, OK      | complex by an ultrafiltration membrane. The        |
|                 | retained complex is precipitated with barium       |
|                 | chloride to regenerate the polymer. This           |
|                 | technology can remove up to 99% of the arsenic     |
|                 | while achieving permeate concentrations below 10   |
|                 | ppb and wasting less than 5% of the water.         |
