22� <br /> C <br /> ONCLUSIONS AND RECOMMENDATIONS <br /> test results for this sampling event indicate slight reductions in the ammonia nitrogen, TKN <br /> pH constituents between the second compartment of the septic tank and all three <br /> nv iroServers. The nitrate-nitrogen concentration was non-detect(ND), but the intermediary <br /> nitrite-nitrogen was present. <br /> The BOD test has significant limitations that may be the cause of the extraordinary test results. <br /> First, the arbitrary 5-day period does not always correspond with the point where all of the waste <br /> material is consumed. Therefore, it is unknown as to where the 5-day BOD value exists on the <br /> curve. Secondly, the requirements of acclimated seed and the potential for nitrification to occur <br /> are questionable. Thirdly, BOD is an aggregate parameter, meaning the individual waste <br /> constituents that constitute the measured BOD value are unknown. Any, or all of these <br /> limitations may prove the reason for the high test results. <br /> The Automatic Distributing Valve (ADV) will be cleaned and serviced when Flow Meter#1 is <br /> replaced, and again in the Fall when the 2°d biannual inspection will occur. The ADV may be <br /> replaced if inspection warrants replacement. As referenced, the faulty Flow Meter#1 will be <br /> replaced as soon as possible. <br /> If there should be any questions regarding the information contained within this Report, please <br /> contact the undersigned. <br /> Respectfully submitted, pFESs� <br /> CHESNEY ENGINEERING, INC. <p�r CH�Sq�� <br /> � Z <br /> C 75479 rn <br /> Don Chesney, PE s�qr CIVIL <br /> Registered Civil Engineer#C75479 OF CA1�Fo <br /> Page -3- <br /> Chesney Engineering, Inc. <br />
