A mobile treatment system is provided for treating contaminates in water, particularly during emergency situations such as natural disasters and planned attacks. The mobile treatment system includes a mobile framework; one or more treatment modules mounted on the mobile framework; a piping system in fluid communication with the one or more treatment modules, said piping system comprising one or more pumps configured to convey water to and from the one or more treatment modules; and at least one power source to provide power to the one or more pumps and one or more treatment modules. The treatment modules may include pre-filtration, chlorination treatment that generates chlorine by electrolysis, activated carbon treatment, and treatment using a disinfecting, silver coated composite material.

Aspects of a detention pond retrofit device for detention basin outlet control provide structures designed to throttle stormwater flow and maintain the rate at which water is discharged from the system below Qcritical, the flow rate at which erosion and down cutting of the receiving stream would begin, based on channel morphology and bed material resistance. The primary goal of the device is to induce increased flow detention during low to moderate rain events, while providing similar hydraulic performance during large events to that of the detention basin performance prior to the installation of the retrofit unit. This is achieved through a 'T' or 'Y' design with split flow paths, in which the lower path is hydraulically restricted through the installation of structures while the upper path is unrestricted.

A method for monitoring water in a distribution system is disclosed where the sensor sampling schedule is changed in real time in response to a contaminant or other chemical passing through the sampling location. This results in finer determination of where the contaminant is located in the water distribution and identification of the contaminant with a lower false rate than random or scheduled sampling.
