One or several of the following corrective procedures may be
required:
Repair or reconstruct the complete water system to keep out
pollutants; then disinfect and retest. If the test results
are satisfactory from 3 or more samples taken 2 weeks apart,
use water. If results are unsatisfactory, either;
Develop new water source; or
Install and properly operate continuous disinfection
equipment.
Install a softener, but only if the water is clear; or
Install a potassium permanganate regenerated oxidizing filter and
a softener. If the water pH is below 7, the acid must be neutralized ahead of the filter.
