Alpha Analytical Laboratories Inc. www.alpha4abs.com WATERS,SEDIMENTS,SOLIDS Homeowner Expanded Analyses Package Collection Procedures: Sample from a sink in the house or a spigot close to the well head, never from a hose. If the tap has an aerator, it should be removed. Sterilize the sampling point with flame or bleach, and then flush for 2 minutes. Fill up the provided bottles, being certain to fill the clear plastic bottle with the banded cap to slightly over the 100ml-fill line. Keep the samples on ice during transport to the laboratory. Arsenic(As)by EPA 200.9 CDPH regulates a maximum of.01 mg/L for public water systems Boron (B) by EPA 200.7 EPA has no drinking water guidelines. For agricultural purposes, below 0.5 mg/L is satisfactory for all crops. Many sensitive crops are affected by 0.5 mg/L—2.0 mg/L, and only tolerant crops produce yields in the 2.0 mg/L—10.0 mg/L range. Ca&Mg(Hardness)by SM2340B Soft=0 to 50mg/L Medium =50 to 100mg/L Hard = 100 to 200mg/L Very Hard=>200mg/L Conductivity by SM2510B <900 umhos/cm is acceptable,while>900 umhos/cm indicates that the water is very high in dissolved minerals. Iron (Fe) by EPA 200.7 CDPH suggests a maximum of.30 mg/L for public water systems Manganese(Mn) by EPA 200.7 CDPH suggests a maximum of.05 mg/L for public water systems Sodium (Na) by EPA 200.7 No official guidelines. The American Heart Association suggests a maximum of 20.0 mg/L for sodium restricted diets. Nitrate(as NO3) by EPA 300.0 CDPH regulates a maximum of 45.0 mg/L for public water systems Nitrite(as N) by EPA 300.0 CDPH regulates a maximum of 1.0 mg/L for public water systems pH by SM4500 Acidic= under 6.5/6.5—8.0=acceptable/Alkaline=over 8.0 Total Dissolved Solids by SM2540C CDPH suggests a maximum of 500 mg/L for public water systems Sulfate by EPA 300.0 CDPH suggests a maximum of 250 mg/L for public water systems Total Coliform and E-Coli Absent/Absent= No coliforms detected. Ideal for treated water. by SM9223 Colisure Present/Absent=Total coliform bacteria was detected, and the water is potentially unsafe, and suitable to disinfect. Present/Present= E-Coli bacteria present, and the water is unsafe.
