Too little lead to measure
8 public water companies list Casa Grande as a place they supply. The biggest is Arizona Water County - Pinal Valley, with about 134,432 people. None of the 8 with results was above 15 at its latest test. 8 found too little lead to measure. 3 are small systems serving fewer than 500 people each, such as a mobile home park, a subdivision or a business with its own well.
