The Central Ground Water Board (CGWB) has stated successful its Annual Ground Water Quality Report-2025 that Andhra Pradesh is 1 of the States facing wide contamination of groundwater arsenic per the BIS standards.
However, the study notes that the monsoon play has shown immoderate betterment successful h2o quality, peculiarly successful the areas affected by precocious Electrical Conductivity (EC) and fluoride.
Post-monsoon, a humble simplification successful EC levels and fluoride has been observed successful immoderate regions, indicating that monsoon recharge tin temporarily amended h2o prime by diluting salts.
“Elevated uranium concentrations exceeding 30 parts per cardinal (ppb) were detected sporadically successful Andhra Pradesh and 4 different States, including Telangana,” the study mentioned.
High incidences of residual sodium carbonate beyond permissible limits were recorded successful Andhra Pradesh (26.87% of the samples analysed).
The groundwater prime alerts issued by the CGWB during June 2024–March 2025 highlighted the precocious incidence of nitrate, iron, fluoride, chromium, cobalt, manganese, nickel, zinc, arsenic, selenium, cadmium, lead, and uranium, with notable concerns successful Andhra Pradesh and 8 different States.
Andhra Pradesh and immoderate different States were recovered to beryllium facing seawater intrusion successful coastal aquifers, which was attributed to precocious levels of electrical conductivity.
Elevated fluoride levels
The CGWB detected elevated fluoride levels successful parts of Andhra Pradesh among different States, which bespeak that fluoride enrichment was mostly confined to circumstantial regions.
High nitrate concentrations were prominently observed successful northwestern and cardinal India, peculiarly successful Rajasthan, Haryana, Punjab, Gujarat, Madhya Pradesh, and Maharashtra, extending further into parts of Andhra Pradesh, Telangana, Karnataka, and Tamil Nadu.
It was established that intensive cultivation practices, excessive fertilizer application, and improper disposal of home and carnal wastes contributed to nitrate enrichment successful those States.
Sixteen villages - Galiveedu, Boreddygaripalli, Basanikonda, Chinnamandyam, Sanipai and Chintaparthi successful Annamayya district, Karivemula and Naganathapalli successful Kurnool district, Alampur, Madakasira, Kambalaparthi, Tanakallu and Asvattharayapuram successful Sri Sathya Sai district, and Damalacheruvu, Mungiliputtu and Balijepalli successful Tirupati territory were recovered to beryllium uranium hotspots exceeding 30 ppb.
Arsenic hotspots
Similarly, 5 villages successful Andhra Pradesh, namely Mulapalem (Bapatla district), Varagami (Guntur), Kartamodu (Nellore), Rompicherla (Palnadu), and Kurichedu (Prakasam) were identified arsenic arsenic hotspots, wherever the attraction of the dense metals exceeds 10 ppb.
Fluoride contamination supra 1.50 mg/L successful areas, particularly hard stone aquifers successful Andhra Pradesh, wherever over-extraction enhances the mobilisation of fluoride-bearing minerals was 1 of the large findings.
