Summary of Water, Air, and Fecal Coliform Sampling Results from July 2-9, 2007

Water Results

July 2, 2007 - Three flood water samples were collected and tested for Volatile Organic Chemicals (VOCs), Semi-volatile Organic Chemicals (SVOCs), Poly-chlorinated Bi-phenyls (PCBs), pesticides and metals. Low levels of the following metals were found in the 3 water samples:  aluminum, barium, calcium, copper, iron, magnesium, manganese, mercury, potassium, titanium, vanadium and zinc.  None of the levels of metals in water exceeded drinking water criteria. Sample #3533-003 contained bis(2-Ethylhexyl)phthalate, an SVOC, at a level of 5.1 ug/L. The EPA Region 9 PRG value for bis(2-Ethylhexyl)phthalate is 4.8 ug/L. This does not pose a public health hazard. Sample #3533-003 contained benzene, a VOC, at a level of 3.4 ug/L, ethyl benzene at a level of 2.1 ug/L, naphthalene at a level of 2.3 ug/L, toluene at a level of 13 ug/L, and m and/or p-Xylene at a level of 6.7 ug/L. These VOCs are not expected to pose a health hazard because the concentrations are lower than health comparison values.  No SVOCs were detected in the samples.  

Comments:
No contaminants of concern were identified for analytes which have health screening criteria.

July 4, 2007 - Three flood water samples were collected and were tested for Volatile Organic Chemicals (VOCs), Semi-volatile Organic Chemicals (SVOCs), Poly-chlorinated Bi-phenyls (PCBs), pesticides and metals. Low levels of the following metals were found in the 3 water samples:  aluminum, barium, calcium, cobalt, copper, iron, magnesium, manganese, mercury, potassium, titanium, vanadium and zinc.  None of the levels of metals in water exceeded drinking water criteria. Low levels of the following VOCs were found in Sample #3535-5:  acetone and methylene chloride. These VOCs are not expected to pose a health hazard because the concentrations are lower than health comparison values. No SVOCs were detected in the samples.

Comments:
No contaminants of concern were identified for analytes which have health screening criteria.

July 5, 2007 - Three flood water samples were collected and were tested for Volatile Organic Chemicals (VOCs), Semi-volatile Organic Chemicals (SVOCs), Poly-chlorinated Bi-phenyls (PCBs), pesticides and metals. Low levels of the following metals were found in the 3 water samples:  aluminum, barium, calcium, cobalt, copper, iron, magnesium, manganese, mercury, potassium, titanium, vanadium and zinc.  None of the levels of metals in water exceeded drinking water criteria. Sample # 3535-7 contained acetone, a VOC. This VOC is not expected to pose a health hazard because the concentration is lower than health comparison values. Sample # 3535-7 contained pentachlorophenol, an SVOC. This SVOC is not expected to pose a health hazard because the concentration is lower than health comparison values.

Comments:
No contaminants of concern were identified for analytes which have health screening criteria.

Air Results

July 2, 2007 – Air sample 3533-101 was collected in a summa canister, and was analyzed for VOCs. This sample contained two VOCs at levels that exceeded health comparison values. At these levels, though, no health threat is expected.

Air sample 3533-102 was collected in a summa canister, and was analyzed for Volatile Organic Chemicals (VOCs). This sample contained levels of VOCs below health comparison values. These levels of VOCs do not pose a health hazard.

Air sample 3533-103 was collected in a summa canister, and was analyzed for VOCs. This sample contained three VOCs at levels that exceeded health comparison values. At these levels, though, no health threat is expected.

July 3, 2007 – Three air samples (3533-104, 3533-105, 3533-106) were collected in summa canisters and analyzed for VOCs. These samples contained levels of VOCs below health comparison values. These levels of VOCs do not pose a health hazard.

July 4, 2007 – Three air samples (3533-107, 3533-108, 3533-109) were collected in summa canisters and analyzed for VOCs. Sample 3533-108  contained 1,2,4-Trimethylbenzene at a level which slightly exceeded health comparison values. At this level, no health threat is expected.

July 5, 2007 – Three air samples (3533-110, 3533-111, 3533-112) were collected in summa canisters and analyzed for VOCs. All three samples contained no VOCs above health comparison values, and no health threat is expected.
July 6, 2007 - Three air samples (3536-114, 3536-115, 3536-116) were collected in summa canisters and analyzed for VOCs. All three samples contained no VOCs above health comparison values, and no health threat is expected.
July 7, 2007 – Four air samples (3536-117, 3536-118-FD, 3536-119, 3536-120) were collected in summa canisters and analyzed for VOCs. All three samples contained no VOCs above health comparison values, and no health threat is expected.
July 8, 2007 –Three air samples (3536-121, 3536-122, 3536-123) were collected in summa canisters and analyzed for VOCs. All three samples contained no VOCs above health comparison values, and no health threat is expected.
July 9, 2007 –Four air samples (3536-124, 3536-125-FD, 3536-127, 3536-128) were collected in summa canisters and analyzed for VOCs. All three samples contained no VOCs above health comparison values, and no health threat is expected.

Fecal Coliform Results

July 4 – 7, 2007 – Thirteen fecal coliform samples were collected. Fecal coliform bacteria in flood waters exceeded the recreational waters standard of 200 CFU/100 ml. These bacterial levels posed a potential health hazard for people coming in contact with the water.

Comments:
If citizens come into contact with flood water contaminated with fecal coliform, the water can cause symptoms such as stomach-ache, fever, vomiting and diarrhea. Persons exposed to fecal coliform (bacteria) can become ill if they have an open cut, wound, or scrape that comes into contact with contaminated water. Symptoms include fever, redness, and swelling at the site of an open wound. If these symptoms occur, a doctor should be consulted.

EPA and Agency for Toxic Substances and Disease Registry (ATSDR) advise citizens to avoid direct contact with standing water when possible. If contact with contaminated water is made, citizens should apply soap and water to clean exposed areas.
