WATER TESTING RESULTS

The water from the system is tested both onsite by church deacons and offsite by an accredited water testing lab. The First Trinity deacons have been instrumental in the bottled water service since 2014. They were involved from the very beginning in landing on what an appropriate testing and reporting structure should be.

Tests for Lead, PH and Dissolved Solids are conducted daily with use, as are measurements of pressure at each filter

Tests for microbiological contaminants are conducted by a certified lab outside of Flint every 1-2 weeks

Additional validation tests for lead and other heavy metals are conducted quarterly.

EXPLANATION OF TEST RESULTS

PH: A measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. Drinking water must have a pH value of 6.5-8.5 to fall within EPA standards.

TDS (Total Dissolved Solids): A measure of the combined total of organic and inorganic substances contained in the water. These solids are primarily minerals, salts and organic matter that can be a general indicator of water quality. ‘Excellent’ drinking water should have a TDS under 300mg/L. The EPA’s recommended maximum level of TDS in water is 500mg/L

Lead: EPA has set the maximum contaminant level goal for lead in drinking water at zero because lead is a toxic metal that can be harmful to human health even at low exposure levels. The lowest threshold we can measure is 0.001mg/L, and we will report any values about this. If levels above .0015mg/L are detected, service from The Water Box will be suspended.

Coliform: A group of 16 species of bacteria used to indicate water quality.  The presence of Coliform indicates bacteria that may be harmful. We will report the presence of any coliform in the water, and conduct further test to determine if the species is a harmful one. If coliform are detected, water service from The Water Box will be suspended.

PSI: A measurement of the pressure at each filter, which we track and use to determine if the filters requires maintenance.

GAL: Indicates the number of gallons of water that have been processed through the system.

NOTES include if the test were conducted by an outside laboratory.
