Welcome to PB Big Bass. When one talks about riprap, I envision material used for bank/erosion stabilization. Greg, Eric or Bob, if lime riprap was placed in the current of a stream, that supplied water to a pond, do you feel this would accelerate the effects (to water pH)?
Side bar: Eric, I've come to the belief that you are a research computer and there is no doubt that you will provide a link to some study that addresses this exact question.
Good question Big Bass
