INTERPRETATION OF RESULTS FOR DRINKING WATER lire analysis performed on this drinking water sample is an examination for the presence of coiifoum organisms in the water and indicates the bacteriological quality of the sample. The presence of coliform organisms la used by health organizations worldwide as an indicator for the possible presence of other disease causing organisms. Two types 01 tests are used to determine the presence of conforms in drinking water- MPN (5 tube method) and MF tests. SATISFACTORY RESULTS: Results of 015 tubes positive from an MPN Coliform analysis and less tttan 2)100 ml from an MF Coliform analysis are SATISFACTORY. Proper system maintenance and bacteriological monitoring should be continued routinely to insure the satety of the water supply. UNSATISFACTORY RESULTS: A, 115 and 215 tubes positive Irom an MPN Coliform analysis and 2/100 mi - 41100 ml from an MF Coliform analysis are UNSATISFACTORY results for a single sample and may be an MCL (Maximum Contami- nant Level) violation as defined in WAC 248-54-740. The presence of coliforms indicate the system is not properly pro- tected against contamination and may bo unsafe for human consump- tion. Unsatisfactory samples should be investigated IMMEDIATELY and follow-up samples submitted. Contact your local health depart- ment or DSHS Regional Office for assistance in determining the source of contamination and corrective procedures. D. 315,4/5 and 5/5 tubus positive from an MPN Colilorrn and 41100 mi and Qraater from an MF Coliform analysis are UNSATISFACTORY results and DO NOT CONFORM with the Slate Board of Health bacteriological standards. For further definition of unsatisfactory and non -conforming samples and MCL violations, see WAC 248.54.740. In this case, the IMMEDIATE ACTION REQUIRED by a Public System 18: 1. Investigate to determine the cause and correct the situation. Your local health derailment or DSHS Regional Office can assist you. 2. Submit at teal two (2) Ioliow-up check samples, or more as spoci- fled in WAC 248.54-710, 3. Publicly notify the users of public water systems as specified in WAC 248-54.750. TEST UNSUITABLE: "Confluent Growth" means bacteria have grown into a continuous mass which makes counting impossible. "TNTC" mes . tcteria are too numerous to count. "Excess debris" means that particulates in the wale* interfere with the interpretation of test results If any box indicating an un- suitable test is checked, the presence of coliform bacteria could not be determined and a new sample must be obtained for testing by another procedure. SAMPLE ro edure- SAMPLE NOT TESTED: The sample was not icsted tor the reason checked and does nut coup' toward fulfillment of any bacteriological mcnitoring requirements. To fulfill the monitoring requirements, another sample must be submitted.
