Passive Water Treatment Systems: What You Need to Know
There are many kinds of passive treatment systems, including: Limestone diversion wells: The main purpose of a limestone diversion well is to naturally reduce the acidity of water by using limestone as a neutralizing agent. This process begins with groundwater flowing through a pipe into a well or pit filled with crushed limestone.

Sand, charcoal, gravel water filtration question | Survivalist Forum
To get good clean water you need to get down to the micron level. Sand filter get down to ~10 microns. Still to large for many bacteria and things like Giardia and Cryptosporidium, which aren't affected by Chlorine. Ceramic filters, like the ones in a Berkey, get it down to ~5 microns.

How to Remove Sediment From Well & Spring Water
Micron cartridge filters: 0.5 to the 100-micron range, remove fine sediment; Sediment backwash filters: filter down to 5 to 10-micron range and are self-cleaning. Often used in conjunction with 1 to 5-micron cartridge filters. Ultrafiltration membranes (UF): filter down to less than 0.15 microns. Remove bacteria; very fine colloidal sediment.

PROCESS DESCRIPTION
Using equations 12 and 13, Letterman, Haddad and Driscoll (1991) developed a steady-state model that relates the depth of limestone required in the contactor to the desired effluent water chemistry, influent water chemistry, limestone particle size and shape, bed porosity, water temperature and superficial velocity (Equation 14). Equation 14.
