Is seems, this also affects public roads. Here is, for example, methodology of application of these waste products to road surfaces in California: https://dot.ca.gov/-/media/dot-media/programs/research-innovation-system-information/documents/preliminary-investigations/brine-application-pi-a11y.pdf https://dot.ca.gov/-/media/dot-media/programs/research-innov... Doesn't seem there is much there on controlling amounts of lead, cadmium and radium in the material. No on the gradual accumulation on the road. As per the following paper, not much research had been done on the health effects of applying it on the roads and risks of dust particles lifted by vehicles being inhailed. https://www.researchgate.net/publication/325460511_Environmental_and_Human_Health_Impacts_of_Spreading_Oil_and_Gas_Wastewater_on_Roads https://www.researchgate.net/publication/325460511_Environme... And from its abstract: "Currently, state-by-state regulations do not require radium analyses prior to treating roads with O&G wastewaters.". So it looks like there is a loophole that doesn't specifically disallow to accumulate unlimited amounts of radioactive material with 1600 years decay half-life on public roads.

> methodology of application of these waste products Linked document is interesting, however it is "Brine Application Equipment and Methodology" - methodology of deicing paved roads. Only mention of toxic or waste is an aside of brine use motivation - granular material in California is for some reason regulated as toxic waste. Mentioned in the document are NaCl, MgCl₂, CaCl₂ brines and beet juice, and in the survey section, some agencies also report use or discontent with proprietary deicing products. Going by the second document, O&G wastewater use on roads is not permitted in California. In the 13 states that do allow its use, the study mostly mentions use on unpaved roads as a dust suppressant in lieu of salt brine (neither a particularly good idea IMO).
