The ambient groundwater monitoring network collects samples for contaminants of emerging concern such as pharmaceuticals, insect repellents, bisphenol A, and alkylphenol detergent breakdown products. This project will fill a data gap by collecting water samples for organophosphate flame retardants and PFAS. Samples will be collected from 135 wells and tested for organophosphate flame retardants and selected wells for PFAS.
Residents of Oronoco historically depended on individual wells for all of their potable water needs. Most of these wells are shallow or sand point types and may have elevated levels of nitrates.The City of Oronoco recently completed the first phase of a municipal water system project that will lessen the citizen dependence on individual wells. As residents are connected to the municipal system their existing wells are no longer needed. The wells should be sealed to prevent possible contamination of the city wells.Grant funds will be used to assist with the cost of sealing these wells.
