No. 16/434,607 filed Jun. 7, 2019, now U.S. Pat. No. 11,407,660; which is a division of U.S. application Ser. No. 13/774,956, filed Feb. 22, 2013, now U.S. Pat. No. 10,358,361. The entire disclosures of each are hereby incorporated by reference. FIELD OF THE INVENTION The invention relates to a system and method for the remediation of wastewater. The remediation includes aerobic and electrocoagulation treatment. SUMMARY Over the last several years, an increase production of livestock and dairy products has resulted in a large quantity of waste that affects air and water quality in the surrounding areas. In addition, mining production also produces waste that is costly and difficult to remediate. Additionally, regulations on carbon dioxide and other byproducts have increased costs for power due to costly remediation methods. In addition, a challenge in municipalities is the treatment of wastewater, including sewage water, stormwater runoff and septic tank waste. Domestic wastewater contains a plethora of residues from cooking, to cleaning to sanitary waste. A growing population puts additional challenges on an already strained system and municipalities struggle to economically and efficiently deal with wastewater. Wastewater treatment facilities play an important role in protecting water quality and the health of the community. Regulations on the federal, state and local levels assist in meeting this important role, but are often times difficult to meet. The present invention addresses these and other problems by meeting the increasingly strict discharge permit requirements set forth by different government regulations. In addition, this present invention relates to a system and method to treat wastewaters from various sources. In addition, the system and method and system may be used to remediate waste that has built up in the bottom of bodies of waters, such as lagoons or tailing ponds, without costly shut downs. The present invention relates to a wastewater treatment system comprising a biological treatment system and an electrocoagulation system. The combination of these systems eliminates a wide spectrum of wastes. Furthermore, each system is complimentary to the other. The biological treatment system eliminates wastes that the electrocoagulation system may not sufficiently remove, while the electrocoagulation system eliminates wastes that the biological treatment system may not sufficiently remove. An aspect of the present invention relates to a system for remediating wastewater. The system comprises a primary cell, a finishing cell and an electrocoagulation cell or unit. The primary cell comprises treatment media that may be used to remove organics, inorganics, simple carbon compound comprising less than six carbon, phosphates, nitrates, ammonia, selenium and combinations thereof. The finishing cell may be used to remove solids, that may have been produced in the primary cell, from the treated water. The electrocoagulation cell reduces at least one secondary contaminant, including but not limited to, organics, inorganics, pharmaceuticals, bacteria, viruses, fecal chloroforms, phosphates, nitrates, metals, radioactive materials (radds) and combinations thereof. The water exiting the electrocoagulation cell may be discharged into public streams or may be recycled within the wastewater treatment system. An aspect of the present invention relates to a method for remediating wastewater. The method comprises processing the wastewater in a primary cell to reduce the biological oxygen demand (BOD) in the wastewater. The finishing cell may decrease the total suspended solid (TSS) in the wastewater. The TSS may have increased due to treatment in the primary cell. The electrocoagulation cell may be used to remove a secondary contaminant. An aspect of the invention is a wastewater treatment system for treating wastewater, the system comprising a primary cell, having a treatment media to treat the wastewater to produce a treated wastewater, the primary cell further having a plurality of plate diffusers and a plurality of baffles for directing flow of the wastewater through the primary cell, and wherein the primary cell reduces BOD in the wastewater by at least about 50%; a finishing cell, to separate the treated wastewater from the treatment media and to reduce TSS in the treated wastewater to produce a further treated wastewater; and an electrocoagulation unit, to further treat the further treated wastewater to produce a purified water. An aspect of the invention is a method of treating a wastewater, the method comprising treating the wastewater in a primary cell, by a treatment media to produce a treated wastewater; separating the treatment media from the treated wastewater; and purifying the treated wastewater in an electroc
