2 Karl Environmental Group Project Lauck Road Mohnton, PA Tel: (800) Fax: (610) Web: February 23, 2017 Ms. Antoinette Kelly Business Administrator Cresskill Board of Education One Lincoln Drive Cresskill, NJ Re: Lead in Drinking Water - Post Remediation Sampling Edward Bryan Elementary School: 51 Brookside Avenue, Cresskill, NJ Merritt Memorial Elementary School: 1 Dogwood Lane, Cresskill, NJ Cresskill Jr./Sr. High School: One Lincoln Drive, Cresskill, NJ Karl Environmental Group Project #: Dear Ms. Kelly: Thank you for selecting Karl Environmental Group ( Karl ) for this project. This report details the methods and findings of the lead in drinking water post-remediation sampling performed for the Cresskill Board of Education at the Edward Bryan Elementary School, the Merritt Memorial Elementary School, and the Cresskill Jr./Sr. High School (the Facilities ), located in Cresskill, New Jersey on February 9, PROJECT BACKGROUND In the Spring of 2017, Karl identified eighteen (18) locations throughout the Cresskill School District that exhibited elevated lead levels after first-draw sampling (see Karl reports and dated May 16, 2016 and July 26, 2016, respectively). Remediation was recommended for these drinking water outlets, after which sampling was necessary to determine the efficacy of the remedial activities. The purpose of the sampling event on February 9, 2017 was to determine if the remediated drinking water outlets were ready to be placed back into service. 2.0 LEAD IN DRINKING WATER Lead is a toxic substance that can be harmful to human health. As compared to adults, children are more susceptible to the detrimental health effects of lead, as their nervous systems are not yet fully developed. VOICE: (610) LAUCK ROAD, MOHNTON, PA FAX: (610)

3 Karl Environmental Group Project Exposure to lead can occur in a variety of ways including through food, soil, deteriorating leadbased paint, and drinking water. Lead can leach into drinking water from plumbing materials such as pipes and solder, as well as brass plumbing fixtures. Post-remediation sampling was conducted after the adoption of N.J.A.C. 6A:26: Educational Facilities requiring the sampling of drinking water for lead in public schools, but was not intended to put the Client in compliance with those regulations. 3.0 DRINKING WATER SAMPLING METHODOLOGY Karl collected drinking water samples from the remediated drinking water outlets throughout each of the Facilities. At each collection point, Karl filled a 250 milliliter (ml) wide-mouth high density polyethylene (HDPE) sample collection bottle. Samples were collected after the water in each building had not been used for at least 8 hours, but not more than 48 hours, and prior to the building s daily opening. The post-remediation sample at each collection point represents a first draw sample. The first draw sample is representative of the water from the end point of the water source (i.e. the bubbler or tap). The samples were recorded under proper chain of custody and couriered to Suburban Testing Labs (Suburban), a New Jersey certified laboratory (NJ Lab ID #PA081) located in Reading, Pennsylvania for analysis by EPA method Karl collected the following number of water samples: Edward Bryan Elementary School Nine (9) First Draw Samples One (1) Field Blank Sample Merritt Memorial Elementary School Two (2) First Draw Samples One (1) Field Blank Sample Cresskill Jr./Sr. High School Five (5) First Draw Samples One (1) Field Blank Sample 4.0 DRINKING WATER ANALYSIS RESULTS The analytical lead in drinking water results for each post-remediation first draw sample are listed in Tables 1-3, below: VOICE: (610) LAUCK ROAD, MOHNTON, PA FAX: (610)

5 Karl Environmental Group Project Laboratory analytical results were compared to the New Jersey Department of Environmental Protection (NJDEP) Drinking Water Quality Standard of 15 ppb for lead. This value coincides with the EPA s Action Level of 15 ppb. Analysis of lead in the first draw post-remediation drinking water samples indicated that at the time of the screening event, four (4) of the samples collected in the Edward Bryan School exhibited a lead level above the Action Level of 15.5 ppb. None of the post-remediation samples exceeded the lead Action Level at Merritt Memorial School and therefore those drinking water outlets can be placed back into service. Four (4) of the drinking water samples from the Cresskill Jr./Sr. High School exceeded the Action Level. Those drinking water outlets that continue to exhibit elevated lead levels should be further remediated by the addition of a lead-removing filter. One (1) sample in the Edward Bryan School (right-hand side porcelain water fountain outside Room 201) exhibited a lead level of 15.4 ppb. While this value is not technically over the 15.5 regulatory Action Level, Karl recommends the addition of a lead-removing filter to this drinking water outlet out of an abundance of caution. All drinking water outlets that receive further remediation should be tested again prior to being placed back in service. 6.0 CONCLUSIONS & RECOMMENDATIONS Karl collected first draw post-remediation water samples from water sources that had been remediated throughout Edward Bryan School, Merritt Memorial School, and the Cresskill Jr./Sr. High School in Cresskill, New Jersey. A total of eight (8) sample results indicated lead levels above the EPA Action Level of 15.5 ppb. Based on the findings of the lead in water screening and observations made during sample collection, Karl offers the following recommendations at this time: Install point-of-use lead-removing filters on the drinking water outlets in the locations from which samples continue to show an exceedance of the Action Level. Regularly replace spent water filters according to manufacturer recommendations to prevent contaminants from passing through to the drinking water port. All plumbing downstream from the filter up to and including a drinking water end point should be lead-free. Sample the left-most fountain at the Cresskill Jr./Sr. High School outside Room B-5 which was not functioning at the time of the initial sampling event in 2016 and therefore has not been sampled during this or any other Karl lead in water screenings. Comply with all requirements set forth by the ammendment to N.J.A.C. 6A:26 Educational Facilities pertaining to Lead in Drinking Water, adopted on July 13, VOICE: (610) LAUCK ROAD, MOHNTON, PA FAX: (610)

6 Karl Environmental Group Project Additional Recommendations: In the event that water drinking source(s) are remediated, the source(s) should be resampled before being placed back into service to ensure the efficacy of the remedial actions. Replace any known or discovered lead piping with with lead-free piping. If a collection point is not used for drinking water, but exhibited elevated lead concentrations above the EPA Action level, place a sign at each collection point indicating the that collection point is not to be used for drinking water. If small children are likely to have access to that collection point, the use of pictures indicated that location should not be used to drink from is recommended. Continue to monitor lead in drinking water levels as part of a regular sampling and maintenance plan. It is recommended that this include sampling any remaining untested drinking water outlets in the Facilities. Additional parameters may also be considered for analysis, such as: Antimony, Asbestos, Cadmium, Copper, Mercury, Nickel, Silver, Zinc, and biologicals. Where in use, regularly clean aerators to prevent the build-up of debris behind the screen which may contribute to elevated lead levels. Use only cold water for food and beverage preparation. Hot water is more likely to contribute to the corrosion of plumbing materials and thefore contain a greater level of contaminants from the plumbing system. Check piping for ground wiring for electricity. Such wiring may cause premature corrosion of the affected piping and lead to contamination of the water contained within. 7.0 LIMITATIONS The purpose of the sampling event outlined within this report was to provide a general screening of potable water sources for potential lead contamination. No other heavy metals or additional contaminants were sampled for or analyzed. Lead concentrations can change as water continues to move through the water system. Each sample was a grab sample and represents lead concentrations only at the specific time of collection and may vary based on the water usage in the facility. Interpretation of these results is only valid if the facility is serviced by a municipal water supplier or water utility. VOICE: (610) LAUCK ROAD, MOHNTON, PA FAX: (610)

7 Karl Environmental Group Project This lead screening event was not intended to comply with the newly adopted amendments to N.J.A.C. 6A:26, Educational Facilities, effective July 13, 2016 which requires testing for lead in the drinking water of public school districts. 8.0 CLOSING Thank you for using Karl to assist you with this project.
