How do municipal utilities screen for water purity?
Depends on local conditions
Household water treatment and safe storage (HWTS) interventions are proven to improve water quality and reduce diarrheal disease incidence in developing countries. Four of these proven HWTS options – chlorination, solar disinfection, ceramic filtration, and flocculation/disinfection – are widely implemented in developing countries.
Organizations wanting to develop HWTS programs are often faced with the difficult decision of selecting which option or options are appropriate for their particular circumstances. The most appropriate HWTS option for a location depends on existing water and sanitation conditions, water quality, cultural acceptability, implementation feasibility, availability of HWTS technologies, and other local conditions.

I guess they screen is based on directives given by the European Commune in Europe.
The EC gets the directives maybe from the WHO, the EC just passes on the directives (without checking the what, why and how) to the countries with 'gentle pressure' to execute accordingly (if compliance, you get some budget, if you don't follow the directive, tough luck ..), then the countries impose these directives on the municipals, again not checking what needs to be checked, why and how..
This is an impression, a guess, so this may be totally wrong (which I hope it is :-) )
