The present invention relates to methods of controlling contaminant flow into a water reservoir, reducing bacterial counts in a water reservoir, and reducing a count of dissolved constituents in a water reservoir, which methods include installing within a reservoir, about an inlet thereof, a boom comprising a support system and a curtain connected to the support system, the curtain being formed of a flexible fabric that allows movement of water therethrough and the curtain having a lower end and an upper end, the boom defining an artificial settling pond into which water, dissolved constituents and particulate matter from the inlet enters. The installation allows for settling of particulate matter larger than a minimum size and consumption of organic materials and dissolved constituents by aquatic vegetative flora and/or bacteria within the artificial settling pond.

What is claimed is: 1. A boom comprising: a support system, a curtain connected to the support system, the curtain being formed of a flexible fabric that allows movement of water therethrough and being sized and configured such that, upon introduction into a body of water, the curtain extends substantially the entire water column; and first and second sample ports positioned on opposite sides of the curtain, each comprising a conduit that has an upper end and a lower end, whereby upon introduction of the boom into the body of water the lower end of each sample port is below the water level. 2. The boom according to claim 1 further comprising ballast secured to a lower end of the curtain. 3. The boom according to claim 1 wherein the boom curtain includes first and second sheets of the flexible fabric and the boom further comprises a gas injection system that includes an outlet positioned between the first and second sheets of flexible fabric. 4. A method of controlling contaminant flow into a water reservoir comprising: defining a critical settling velocity for particulate matter entering into a reservoir at an inlet; determining a required surface area for a portion of the reservoir which is to function as an artificial settling pond; and installing within the reservoir, about the inlet, a boom comprising a support system, a curtain connected to the support system, the curtain being formed of a flexible fabric that allows movement of water therethrough and being sized and configured such that, upon introduction into a body of water, the curtain extends substantially the entire water column, and first and second sample ports positioned on opposite sides of the curtain, each comprising a conduit that has an upper end and a lower end, whereby upon introduction of the boom into the body of water the lower end of each sample port is below the water level; wherein the boom defines the artificial settling pond into which water and particulate matter from the inlet enters; wherein particulate matter larger than a minimum size settles from suspension within the artificial settling pond and at least a portion of particulate matter smaller than a minimum size is filtered by the curtain; and wherein water samples obtained from the opposite sides of the curtain, via the first and second sample ports, allow for assessing efficacy of the boom in controlling contaminant flow into the reservoir. 5. The method according to claim 4, wherein the boom curtain includes first and second sheets of the flexible fabric and the boom further comprises a gas injection system which includes an outlet positioned between the first and second sheets of flexible fabric, said method further comprising: injecting gas into the water between the first and second sheets of flexible fabric, said injecting removing particulate matter impinging upon one or both sheets of flexible fabric. 6. A method of reducing bacterial counts in a water reservoir into which bacteria and other pollutants are introduced from storm water runoff via natural or man-made inlets, the method comprising: defining a critical settling velocity for particulate matter entering into a reservoir at an inlet; determining a required surface area for a portion of the reservoir which is to function as an artificial settling pond; and installing within the reservoir, about the inlet, a boom comprising a support system, a curtain connected to the support system, the curtain being formed of a flexible fabric that allows movement of water therethrough and being sized and configured such that, upon introduction into a body of water, the curtain extends substantially the entire water column, and first and second sample ports positioned on opposite sides of the curtain, each comprising a conduit that has an upper end and a lower end, whereby upon introduction of the boom into the body of water the lower end of each sample port is below the water level, wherein the boom defines the artificial settling pond into which water and particulate matter from the inlet enters; wherein organic particulate matter larger than a minimum size settles from suspension within the artificial settling pond, a bacterial population in the artificial settling pond feed upon and decompose the organic matter, and upon partial depletion, the population thereof diminishes; and wherein water samples obtained from the opposite sides of the curtain, via the first and second sample ports, allow for assessing efficacy of the boom in reducing bacterial counts in the water reservoir on the downstream side of the curtain. 7. The method according to claim 6, wherein the total quantity of organic matter passing into the reservoir is diminished by the presence of the artificial settling pond and the bacterial population within the reservoir is substantially reduced. 8. The method according to claim 6, wherein the boom curtain includes first and second sheets of the flexible fabric and the boom further comprises a gas injection system which includes an outlet positioned between the first and second sheets of flexible fabric, said method further comprising: injecting gas into the water between the first and second sheets of flexible fabric, said injecting removing particulate matter impinging upon one or both sheets of flexible fabric. 9. A method of controlling contaminant flow into a water reservoir comprising: defining a critical settling velocity for particulate matter entering into a reservoir at an inlet; determining a required surface area for a portion of the reservoir which is to function as an artificial settling pond; installing within the reservoir, about the inlet, a boom comprising a support system and a curtain connected to the support system, the curtain including first and second sheets of a flexible fabric that allows movement of water therethrough and the curtain having a lower end and an upper end, the boom defining the artificial settling pond into which water and particulate matter from the inlet enters, and the boom further comprising a gas injection system which includes an outlet positioned between the first and second sheets of the flexible fabric; and injecting gas into the water between the first and second sheets of flexible fabric, said injecting removing particulate matter impinging upon one or both sheets of flexible fabric; wherein particulate matter larger than a minimum size settles from suspension within the artificial settling pond and at least a portion of particulate matter smaller than a minimum size is filtered by the curtain. 10. A method of controlling contaminant flow into a water reservoir comprising: defining a critical settling velocity for particulate matter entering into a reservoir at an inlet; determining a required surface area for a portion of the reservoir which is to function as an artificial settling pond; installing within the reservoir, about the inlet, a boom comprising a support system and a curtain connected to the support system, the curtain being formed of a flexible fabric that allows movement of water therethrough and the curtain having a lower end and an upper end, the boom defining the artificial settling pond into which water and particulate matter from the inlet enters; wherein particulate matter larger than a minimum size settles from suspension within the artificial settling pond and at least a portion of particulate matter smaller than the minimum size is filtered by the curtain; defining a critical settling velocity for particulate matter that is smaller than the minimum size of the artificial settling pond and passes through the curtain of the boom; determining a required surface area for a second portion of the reservoir which is to function as a secondary artificial settling pond; and installing within the reservoir, about the first boom, a second boom comprising a support system and a curtain connected to the support system, the curtain being formed of a flexible fabric that allows movement of water therethrough and the curtain having a lower end and an upper end, the boom defining the secondary artificial settling pond into which water and particulate matter from the artificial settling pond enters; wherein particulate matter smaller than the minimum size of the artificial settling pond but larger than a minimum size for the secondary settling pond settles from suspension within the secondary artificial settling pond. 11. A method of reducing bacterial counts in a water reservoir into which bacteria and other pollutants are introduced from storm water runoff via natural or man-made inlets, the method comprising: defining a critical settling velocity for particulate matter entering into a reservoir at an inlet; determining a required surface area for a portion of the reservoir which is to function as an artificial settling pond; installing within the reservoir, about the inlet, a boom comprising a support system and a curtain connected to the support system, the curtain being formed of first and second sheets of a flexible fabric that allows movement of water therethrough and the curtain having a lower end and an upper end, the boom defining the artificial settling pond into which water and particulate matter from the inlet enters, and the boom further comprising a gas injection system which includes an outlet positioned between the first and second sheets of flexible fabric; and injecting gas into the water between the first and second sheets of flexible fabric, said injecting removing particulate matter impinging upon one or both sheets of flexible fabric; wherein organic particulate matter larger than a minimum size settles from suspension within the artificial settling pond, a bacterial population in the artificial settling pond feed upon and decompose the organic matter, and upon partial depletion, the population thereof diminishes.
