Waste stream management system and method

A contaminant management system, comprising:

• a scouting unit including a signal receiver configured to receive at least one signal indicative of a geospatial location of the scouting unit relative to a land area, at least one processor, and a non-transitory computer readable medium storing processor executable code, which when executed by the at least one processor, causes the at least one processor to map one or more georeferenced points indicative of a perimeter including a portion of the land area where a volume of fluids including a concentration of at least one contaminant is to be applied, and to transmit a first signal over a computer network indicative of the one or more georeferenced points indicative of the perimeter;
• a control center including at least one first processor and a first non-transitory computer readable medium storing first processor executable code, which when executed by the at least one first processor, causes the at least one first processor to:
• receive the first signal via a computer port coupled with the computer network;
• access data indicative of a contaminant profile of the at least one contaminant in the portion of the land area in the perimeter;
• access data indicative of a maximum allowable amount of the at least one contaminant in the portion of the land area in the perimeter;
• generate a contaminant capacity profile for the portion of the land area in the perimeter based at least in part on the contaminant profile of the at least one contaminant in the portion of the land area in the perimeter and the maximum allowable amount of the at least one contaminant in the portion of the land area in the perimeter;
• an applicator unit including:
• a movable container;
• a valve assembly including a variable flowrate valve and an actuator operably coupled with the variable flowrate valve and configured to incrementally open, close, or maintain a position of the variable flowrate valve;
• a controller operably coupled with the actuator and including a location signal receiver configured to receive at least one signal indicative of a geospatial location of the applicator unit relative to the land area, at least one second processor, and a second non-transitory computer readable medium coupled with the at least one second processor and storing second processor executable code which when executed by the at least one second processor, causes the at least one second processor to access the contaminant capacity profile, access data indicative of a concentration of the at least one contaminant in a volume of fluids loaded in the movable container;
• and provide a control signal to the actuator to cause the actuator to incrementally open, close, or maintain the position of the variable flowrate valve based at least partially on the geospatial location of the applicator unit relative to the land area.
