Limestone Stream Map of Pennsylvania
The average limestone stream has a pH of 6.5 to 8.0, where the non-limestone stream ranges from a pH of 4.0 to 5.5. Limestone is a natural buffer against the problem of acid rain and other acid sources like acid mine drainage. Water with an acidic pH is harmful to trout. An extreme alkaline pH is also harmful to trout.

Limestone: The Calcium Carbonate Chemical Sedimentary Rock
Some deposits have chemical grades as high as 95% CaCO 3. However, some areas are completely without any suitable limestone deposits. Most of the cost of limestone to the customer is determined by how far away it comes from and how it is shipped. Shipping by barge on water is cheaper than by train which, in turn, is cheaper than shipping by truck.
